Abstract: Provided is a motor device in which the entire length of a motor can be shortened as much as possible while the positional deviation of a shaft in a thrust direction is prevented and a shaft length sufficient to suppress the inclination of the shaft can be ensured. A motor device provided with a shaft with a rotor fixed on the outer surface thereof, and a thrust pressurization unit that supports an end opposite the output side of the shaft while pressurizing the end in an axial direction may be configured so that the thrust pressurization unit may be provided with a coil spring that pressurizes the end opposite the output side of the shaft in the axial direction and the thrust pressurization unit may be disposed inside the rotor.

Abstract: The invention relates to a pivot joint structure of the motor rotor including a spindle and a snap ring. The spindle is centrally disposed in the rotor and the end thereof near the urging part has a scoop channel with smaller outer diameter. The urging part has at least one plane surface along the axial direction and the cross section is formed in a non-circular shape. The center hole of the snap ring takes the shape corresponding to that formed by the cross section(s) of the urging part and the gap therebetween provides a minimum space for the inserting in the urging part. Consequently, regardless of the assembly or disassembly of the rotor, the snap ring structure won't be affected and the deformation or fracture thereof won't take place.

Abstract: A bushing structure 10 is constructed and arranged to be operatively associated with a shaft 24 of an electric motor 22. The motor has a housing 30 including a generally elliptical recess 32 therein defined along an axis C of the shaft. The bushing structure includes a generally cylindrical bushing member 12 constructed and arranged to engage an end of the shaft so as to locate the shaft with respect to the housing and to prevent lockup of the motor. An endplay member 20 is associated with the bushing member and with the end of the shaft. The endplay member includes a spherical portion constructed and arranged to be received in the elliptical recess so as to control endplay of the shaft.

Abstract: A bearing structure for a stepping motor including a stepping motor, a screw shaft integrated with the stepping motor, and a bearing member formed of a molding resin material for supporting a distal end of the screw shaft, wherein a cone-shaped recess is formed in the distal end of the screw shaft, and a dome-shaped projection to be in abutment with the recess is formed on the bearing member.

Abstract: The invention relates to a drive device for a vehicle rearview mirror, the positioning of which is achieved by means of a worm gear mounted by means of a coupling part in a single bearing, which is provided with an annular collar that engages in an upper annular slot of the coupling part. The intention is to improve the retaining force of the bearing.

Abstract: A method for making a first object (1) which can be fixed with great precision with respect to a second object (2) comprises the steps of pressure-casting the first object from a plastically deformable, relatively soft metal such as light metals and zinc alloys, sizing the first object (1) at least in the area of desired surfaces (12, 13, 14) of contact between the first object (1) and the second object (2) by pressing the first object (1) into a sizing tool which consists of a hard material and has in the area of the contact surfaces (12 to 14) a negative form with respect to the desired form of the first object (1), the first object (1) undergoing a plastic deformation at least in the area of the contact surfaces (12 to 14). The additional step is performed of applying a relatively hard metal surface coating to the first object (1) at least in the area of the contact surfaces (12 to 14) (FIG. 1 ).

Abstract: A shaving apparatus comprises a housing; an external shaving member formed with hair-entry apertures and engaging the housing; and an internal shaving member associated with the external shaving member and rotatable relative thereto. A drive shaft couples the internal shaving member to a motor, the drive shaft having a hub. A pin engages the hub for rotatably supporting the drive shaft. Two separate radially acting cylindrical bearing surfaces of different diameters are provided on the pin. Two separate cylindrical radially acting bearing surfaces of correspondingly different diameters are provided on the hub for cooperation with the respective separate radially acting cylindrical bearing surfaces provided on the pin. A supporting plate is provided within the shaving apparatus housing, the pin and the supporting plate being formed as a one-piece plastic unit.

Abstract: The trackball device includes two supports for the trackball, each of which has a code wheel associated therewith. The journals on the end of each shaft and the bearing surfaces of the pillow block associated with the shaft are constructed to have substantially point contact and thereby minimize friction.

Abstract: A support assembly for a washing machine includes a mount secured to the assemblage of working parts of the machine and adapted to move with the assemblage during operation of the machine and a cabinet structure enclosing the assemblage of working parts and having a base. An intermediate member is positioned between the mount and the base for movably supporting the mount and the assemblage of moving parts from the base. The base and intermediate member are formed with a first set of mating support surfaces for sliding movement therebetween and the mount and the intermediate member are formed with a second set of mating support surfaces for sliding movement therebetween. One set of the support surfaces is smoothly curved with a relatively short radius of curvature to form a first node for movement of the mount and the other set of support surfaces is smoothly curved with a relatively long radius of curvature to form a second node for movement of the mount.

Abstract: A support assembly for a washing machine includes a cabinet structure for enclosing the various working parts of the machine and a mount secured to the assembly of working parts of the machine for movement therewith. The cabinet base has an upwardly facing generally spherical bearing surface and the mount includes a generally spherical lower support surface. An intermediate member is positioned between the bearing surface and support surface and is formed with opposed spherical faces complimentary to the bearing surface and to the support surface respectively.
