Abstract
PURPOSE:To extend the substantial life of a piston by making a lock pin on the top end part of a piston pin exchangeable at need against other parts. CONSTITUTION:A piston shaft 3 is inserted into the inner part of a cylinder 1, and on its top end part, a lock pin 4 capable of engaging and disengaging to a through hole provided on a chassis 19 is mounted through a pin stopper body 14. The lock pin 4 is fixed to the piston shaft 3 by a pin stopping lock body 15. When the top end part of the lock pin 4 is damaged by actions such as impact forces thereto and unexpected directional local forces at the time of protruding and recessing during the use of the piston, the lock pin 4 is isolated from the chassis 19 as occasion demands, and the part of the lock pin 4 is exchanged against other parts. Hence, the substantial life of the piston can be significantly extended.
