置。 a first collar and a second collar fitted into holes penetrating the first members installed on the left and right, respectively;
A pin is inserted into a bushing fixed to a second member fitted between both collars, and a spacer ring is provided in a counterbore formed between both end faces of the second member and an outer end face of the bushing. In addition to attaching the seal, the first collar for positioning the pin is fixed to the outer periphery of one side of the pin, and the second collar is fitted to the outer periphery of the other side of the pin. In a pin joint device in which the bushing and both collars are mutually rotatable by protruding into respective counterbores so as to make ends thereof come into contact with the seals, the second collar is divided into an inner part and an outer part, An oil-filled work machine pin joint device characterized by integrally baking rubber between them.
