ン結合部のがた除去装置。 At the pin joint where the bracket and boss are rotatably connected by a connecting pin, a bushing with a flange is slidably inserted in the hole of one side of the bracket in the axial direction, and a bushing with a flange is inserted into the inner diameter of the bushing with a flange. A stepped portion is provided so that the inner diameter of the inner diameter of the bushing with a flange becomes larger, and an outer diameter portion of the head of the connecting pin is formed so as to be able to come into contact with the stepped portion of the inner diameter portion of the bushing with a flange. A grease cylinder part is bored at the end on the head side, and a lid body is provided on the head side of the connecting pin, and a piston part having a greasing passage is provided protruding from the lid body. The piston part of the body can be fitted into the grease cylinder part at the end of the connecting pin to form a grease chamber, and the lid body is fixed to the outer part of the bracket, so that it is possible to supply grease to the grease chamber from the outside. A device for removing play in a pin joint portion, characterized in that:
