Abstract: A driving force transmission device includes a rim having a toothed outer periphery, with bottom lands being formed between respectively adjacent teeth and top lands being formed at teeth crests. Outer ribs are disposed at positions on an inner peripheral surface of the rim corresponding to the bottom lands, whereby there is neither variance in angle speed nor uneven rotation of a member driven by the transmission device. Moreover, the outer ribs are radially offset from inner ribs, whereby tensile forces generated between the outer and inner ribs and caused by material shrinkage cancel each other out and defective molding of teeth crests can be minimized. Accordingly, the radius of an imaginary circle formed by joining the top lands is uniform in a circumferential direction.

Abstract: A clip for attaching an ornamental member to a wall member such as a vehicle body panel. The clip has a head continuously connected with a portion locking the ornamental member. The head is pressed against one surface of the wall member. The clip also has a leg extending from the head and is inserted into a through hole in the wall member. Pawls are formed at a maximum diameter portion of the leg and pressed against the other surface of the wall member to fixedly hold the leg onto the wall member. Pliable thin-walled resin is coated through secondary forming around the respective outer peripheries of the pawls and the leg for preventing damage of an inner periphery of the through hole when the leg is inserted into the through hole.

Abstract: A fastener includes a female body and male body. By forcibly inserting the male body into a male body insertion hole of the female body, the two bodies are temporarily coupled together. By further inserting the male body into the female body from this state, leg portions of the female body are caused to flare outwardly so that overlapped plates are fastened together between the flared leg portions and a head portion of the female body. By further inserting the male body into the female body from this state, the leg portions are released from the flared state, so that the plates can be unfastened. When and only when the leg portions are inserted through a hole of a plate to be fastened by means of the fastener disposed in the temporarily coupled state, can the male body be further inserted within the female body so as to fasten the two plates to each other.

Abstract: A visor/mirror assembly comprising a visor subassembly having a visor, and a vanity mirror subassembly mounted to the visor. The vanity mirror subassembly comprises a mirror supported by a mirror frame on the visor, and a mirror cover hingedly mounted to the mirror frame for swinging between a closed position and an open position with respect to the mirror. A locking mechanism normally holds the mirror cover in the closed position against the force of a spring energizing the mirror cover toward the open position. Connected between the mirror frame and the mirror cover is a fluid damper which acts in opposition to the force of the spring for retarding the pivotal displacement of the mirror cover from the closed to the open position when the mirror cover is unlocked by finger pressure on the locking mechanism. With its momentum so reduced, the mirror cover comes to rest in the open position without shock or noise.

Abstract: A device for fastening bar-like objects upon a mounting surface as a result of being mounted upon a stud projecting downwardly from the mounting surface includes a body having a holding section for holding a bar-like object and a stud insertion hole which extends in a direction substantially perpendicular to the longitudinal direction of the bar-like object and which has a locking shoulder portion upon an inner wall thereof, and a belt like holding sheet provided around the body and having at least one end portion capable of being inserted through the stud insertion hole along an inner wall surface thereof.

Abstract: A drink container holder comprises a storage case built within the body of an automobile, a base framework having an annularly perforated portion able to enter and leave the storage case, an annular holding framework disposed within the perforated portion of the base framework, an intermediate swingable body interposed between the base framework and the holding framework and pivotably attached to the base framework and the holding framework respectively, and a cup holding frame pivotably attached to the holding framework in a suspended fashion.

Abstract: A drink container holder comprises three members: a mounting base having a mounting device for mounting within a vehicle such as an automobile, a holding framework for holding a cup, and an intermediate pivotable framework interposed between the mounting base and the holding framework, the three members being pivotably connected to one another through means of pivotable shaft bearing portions. The mounting device comprises a substantially inverted U-shaped bracket, and the mounting base has dependent bearing portions integrally suspended therefrom. A substantially U-shaped bail member is provided upon the holding framework, and the mounting base, holding framework, and intermediate framework are pivotable with respect to each other about two axes orthogonally arranged with respect to each other such that the three members define in effect gimbal rings for supporting the drink container.

Abstract: An oil damper is disclosed which comprises a cylindrical case open at one end and having a first engagement section formed upon the inner periphery thereof, an intermediate rotor having an inner cylinder and an outer cylinder, these cylinders being coaxial with respect to each other and defining an annular space open at one end, the outer periphery of the outer cylinder being provided with a second engagement section to be engaged with the first engagement section, the intermediate rotor being accommodated within the cylindrical case for rotation in only one direction, a cylindrical shaft rotor rotatably accommodated within the annular space, and viscous oil sealed within the annular space.

Abstract: A screw grommet has a flange and a leg extending therefrom and has cantilever-like engagement projections extending tangentially with respect to the outer periphery of the leg. A panel can be held clamped between the flange and engagement projections. When inserting the leg through an opening in the panel, the engagement projections are easily flexed to facilitate the insertion.

Abstract: A hook device for an ornamental button on a seat cover comprises a C-shaped main hook to be hooked on a spring rod disposed on the inner side of a cushioning material, an auxiliary hook extending integrally from the end of the main hook in the opposite direction thereto to be hooked on a lock piece of the ornamental button, and a closing piece extending from the end of the main hook toward a free end thereof and having elasticity. The opening of the main hook is closed by the closing piece at all times.

Abstract: A locking device has a slide accommodated in a stationary casing and spring biased in the direction causing it to project out of said stationary casing. When the slide is retracted into said stationary casing, a locking arm which is pivotally coupled to the slide is turned to a position facing the exposed end of the slide where it catches an engagement member between itself and the end of the slide. The slide can be locked in a retracted state by a cam member. When the slide is released from the locked state by the cam member, the locking arm can be brought away from the end of the slide.

Abstract: A ball joint in which the ball of a ball stud is accommodated in an accommodating section of a socket. The accommodating section has an annular seat on which a stopper is provided and a cap to be fitted in the accommodating section has another stopper. The two stoppers are received in a gap in an elastic ring-like member mounted in the annular seat such that a turning of the cap will increase the width of the gap to increase the diameter of the elastic ring-like member. In this state, the ball of the ball stud can be accommodated in the accommodating section of the socket.

Abstract: A rotary damping device has a shaft provided at one end with a rotor and the shaft also has a damping portion extending radially. The shaft is rotatably housed and accommodation spaces in the device are filled with oil. Located near to the opening of the shaft bearing is a radially extended sucker-shaped flange having a surface sloped axially forward. When the flange is contained within the accommodation space the rim portion of the flange presses against the front wall of the space to prevent damping oil leaking from the housing.
