  • Patent number: 9909639
    Abstract: 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.

  • Patent number: 9677639
    Abstract: 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.

  • Patent number: 8857583
    Abstract: A hydraulic shock absorber that can reduce outflow amount of oil by maximally removing an oil film attached to an outer periphery of a rod and that can achieve securement of high slidability between the rod and a rod packing and prevention of wear of the rod packing. A rod packing interposed between an outer periphery of a rod and an inner periphery of a rod-side end wall includes a first lip for scrapping off an oil film attached to the outer periphery of the rod, and a ring-shaped grease holding member for supplying holding grease to the outer periphery of the rod. The grease holding member is in contact with the outer periphery of the rod at a position closer to a rod distal end than the first lip.
