摘要： A shock absorber includes a cylinder housing including a piston chamber in which oily liquid is disposed, a piston movable in the piston chamber, a rod connected to the piston and protruding out from the cylinder housing, and a return mechanism for the rod. In the shock absorber, a cylindrical bearing made of a synthetic resin having a shock-absorbing property, a dust collecting member for avoiding entry of dust particles, and a lubricating member for supplying a lubricating oil to a surface of the rod are disposed in a rod guiding hole in the cylinder housing. A leading end of the bearing protrudes outside with respect to an outer end surface of the cylinder housing and acts as a contact portion that allows a moving object to come into contact therewith, and thus the bearing functions to guide the rod and also functions as a stopper for avoiding the moving object from coming into contact with the outer end surface of the cylinder housing.

摘要： A bidirectional shock absorber includes a cylinder housing including a liquid chamber, a shock-absorbing mechanism located inside the liquid chamber and supported by a rod sticking out of the cylinder housing. The shock-absorbing mechanism includes a pair of pistons located in the liquid chamber and attached to the rod on the respective sides of a liquid storage chamber constituting an accumulator, resistance paths formed between an outer circumferential surface of the pistons and an inner circumferential surface of a piston chamber, to apply flow resistance to the liquid, and unidirectional flow paths formed along the respective pistons and configured to block the liquid flow toward the liquid storage chamber when the corresponding piston is pressed toward the piston chamber, but to permit the liquid to flow in the opposite direction.

摘要： An actuator is equipped with a body and a slider. Body side rail grooves are formed in side wall portions that constitute the body. On the other hand, slider side rail grooves are formed in the slider. Body side guide rails and slider side guide rails are provided in the body side rail grooves and the slider side rail grooves, respectively. Circular arc grooves serving as ball grooves are formed by body side ball receiving portions of the body side guide rails, and slider side ball receiving portions of the slider side guide rails.
