構成したことを特徴とするピン固定装置。 A pin joint part in which one bracket member having a connecting pin insertion hole and a boss member serving as the other member are rotatably connected to each other by a connecting pin, and a stopper boss for fixing the connecting pin is provided protruding from the outer side of the bracket. A recessed groove extending all the way around the outer periphery of the stopper boss is provided, and a stepped through hole for the lock pin is formed in the stopper boss and the connecting pin, passing through the recessed groove and penetrating in the diametrical direction. A stepped part is provided on one thick part of the stopper boss,
The diameter of the hole near the outer periphery of the thick part is set to be smaller than the diameter of the lock pin to form a small diameter hole, and when fixing the connecting pin, the lock pin is inserted into the stepped through hole, and then the groove is inserted into the groove. A pin fixing device characterized in that a ring with an elastic locking portion can be fitted therein, and the locking portion of the ring can be inserted into the small diameter hole of the through hole.
