<p><P>PROBLEM TO BE SOLVED: To provide a shock absorber including a novel piston stopper mechanism good in assembling efficiency and capable of stopping a piston at a required position. <P>SOLUTION: In the shock absorber 11, an elastic pawl 45 as a structural member of a piston stopper 19 engages with a circumferential groove 35 engraved in the inner periphery wall of a cylinder 13 to constrain the axial movement of the piston stopper 19. At this time, when the tensile force of a load operates on the piston 15 via a piston rod 17, the tensile force is supported by an abutment face 41a of the piston stopper 19 but the axial movement of the piston stopper 19 remains constrained. Thus, the piston 15 can be reliably stopped at a required position. <P>COPYRIGHT: (C)2010,JPO&amp;INPIT</p> |
