Abstract: A selecting switch includes a case; a slider; a first actuator that rotates downward as pushed down by the slider; a second actuator holding a movable contact; a contact to be contacted by the movable contact; a cam protruding portion that is rotatably born by the second actuator and that contacts a lower inclined surface of the first actuator; a cam that rotates downward upon the cam protruding portion being pushed down while sliding on the lower inclined surface; and a biasing member that biases the cam upward. Upon the first actuator being rotated downward by an angle, the cam protruding portion slides up toward a top of the lower inclined surface by biasing force from the biasing member, and the cam pulls up the second actuator, and a conductive state between the movable contact member and the fixed contact is to be switched.

Abstract: A movable unit is to be provided in an interior of a switchover switch that includes a casing and a slider. The movable unit includes: a cam configured to be rotationally moved downward by a tip end portion of the cam being depressed in response to the slider being depressed; a retaining member configured to retain a movable contact member and support a rotational movement pivotal portion of a base end portion of the cam so as to be movable rotationally and slidable in an upward-downward direction; and a biasing member interposed between the cam and the retaining member and configured to bias the cam upward.

Abstract: In a fluid pressure cylinder, a piston is displaced in an axial direction under the action of a pressure fluid. A circular protrusion, which projects toward the piston along an axial direction of the cylinder tube, is formed on an inner end surface of a collar member constituting part of the fluid pressure cylinder, a concavity, which can be fitted externally over the circular protrusion, is formed on the piston, and an annular groove is formed on an inner circumferential edge of an end plate. By the piston coming into contact with the end plate, a pressure receiving chamber is formed between the piston and the annular groove, together with an opening of a second port on an inner side of the cylinder tube being closed to a maximum of 90%.

Abstract: The piston 4 comprises a fixing ring 8 mounted on a piston rod 6, and a piston body 10 fixed to the fixing ring 8. The fixing ring 8 is comprised of two semi-circular plated members 8A, 8B having plural threaded holes 8a for bolt-fastening of the piston body 10. When they are abutted against each other and formed into a circular-annular shape, a hole portion 8c which is to be tightly fitted in a fixing groove 6a of the piston rod 6 is formed. The piston body 10 has a hole portion 10a which is to be fitted over the piston rod 6, and plural bolt holes 10c corresponding to the threaded holes 8a. Moreover, the piston body 10 has a concave portion 10d on a side of one surface thereof, in which the fixing ring 8 is fitted in an embedded state.

Abstract: The present invention has a spool mounted on a spool shaft and rolled thereon with a fishline, a rotor rotated by a rolling operation of a handle and enabling to roll the fishline round the spool via a fishline guiding part, and a changeover mechanism installed between the spool and the spool shaft for changing over the spool to the dragging operation state and the dragging free state, characterized in that the spool is rotated in an opposite direction to a fishline drawing direction when the spool is under a spool dragging condition, thereby to release a connecting state of the changeover mechanism and to change over the spool under a dragging free state.

Abstract: A rodless cylinder has adjusting mechanisms, each comprising a gear shaft rotatably mounted in a hole defined in an outer wall of a slide table and having a first gear on an end thereof, an adjustment shaft having a second gear on an end thereof which is held in mesh with the first gear at a predetermined angle, and a rod coupled to an opposite end of the adjustment shaft out of alignment with a central axis of adjustment shaft, with a guide roller being rotatably supported on the rod. When the gear shaft is turned by a screwdriver bit inserted in the hole, the adjustment shaft is turned to displace the guide rod for optimum rolling contact with a rail on a cylinder tube. The rolling contact between the guide rod and the rail can be adjusted from the outer side of the slide table.

Abstract: A rodless cylinder for feeding a workpiece has a cylinder having a cylinder tube with a bore defined therein and a piston reciprocally movably disposed in the bore. The cylinder tube has a slit defined therein and extending longitudinally therealong, the slit communicating between the bore and an exterior space. The slit is closed by a first seal member engaging the piston and a second seal member engaging a slide table. The piston has a separator separating the first and second seal members from each other. The cylinder tube has a pair of slanted first surfaces positioned one on each side of the slit. A pair of slide members is disposed on the slide table and have respective second surfaces engaging the first surfaces, respectively, for guiding the slide table when the piston reciprocally moves in the bore and bearing a load applied to the slide table.
