ことを特徴とするピン固定装置。 A boss member is rotatably connected to the bracket member via a pin, and a rotation stopper boss into which one end of the pin can be inserted is fixedly provided on the outside of the bracket member, and the rotation stopper boss and the pin are connected in a diametrical direction. A through hole is provided, a lock pin is inserted into the through hole, and an elastic ring is fitted to the outer periphery of the locking boss to hold the lock pin. A V-shaped groove whose opening outside width is smaller than the diameter of the through hole is formed around the entire circumference on the outer periphery of the rotation stopper boss at the position provided, and an elastic ring can be fitted into the V-shaped groove. When the lock pin is inserted into the through hole and the pin connection is performed, the outer diameter of the elastic ring fitted in the V-shaped groove is set to be slightly larger than the outer diameter of the rotation stopper boss. A pin fixing device characterized by:
