<p>PROBLEM TO BE SOLVED: To prevent a bush from slipping off by forming a thrust washer whose pin hole diameter is smaller than the outside diameter of the bush and larger than the outside diameter of a pin, fixing the inner surface to the boss end surface to which the bush is fitted, and facing the outer surface to the boss end surface. SOLUTION: In a pin connecting part in which a boss member 11 on which a cylindrical bush 16 is mounted and a bracket member are rotatably connected to each other through a pin 22, a thrust washer 12 whose pin hole diameter (d) is small than the outside diameter D0 of the bush 16 and larger than the outside diameter D1 of the pin 22 is formed by forming an axial pin hole 18 in the center part. The inner surface O of the washer 12 is fixed to the end surface of a boss 15L of a boss member 11, and the outer surface M is faced to the boss end surface of the counterpart bracket member. Accordingly, the bush 16 can be prevented from slipping off toward the boss of the counterpart boss bracket member even if force in the thrust direction acts on the bush 16.</p> |
