特徴とする建設車両のピン結合装置。 In a pin coupling device in which a bracket and a boss are rotatably connected by a connecting pin, a stepped portion is provided on the outer diameter of the flanged bush, and an inner diameter opposite to the stepped portion of the flapped bush is provided on the inner diameter of the boss. Provide a stepped part, fit the bushing with a flange into the inner diameter part of the boss in a loose state, and install a rotation stopper to prevent mutual rotation of the boss and the bush with a flange,
Furthermore, the pin for a construction vehicle is characterized in that a sealing member is provided to keep the stepped portion in an oil-tight state, and a grease passage is bored in the boss to communicate the outer diameter portion of the boss with the stepped portion. Coupling device.
