。 A bushing member with a flange that can be slid in the direction of the pin axis is provided at both ends or one end of the boss member, and when the bracket member and the boss member are connected by a pin, the end face of the flange portion of the bushing member is applied with grease pressure. In the pin joint part that can be pressed against the inner end surface of the bracket member, a spacer is installed around the entire outer circumference of the pin on the inner circumference of the flanged bushing member, on the opposing end surface side of the flanged bushing member and the bracket member. A spacer piston is fitted into the spacer chamber so as to be able to slide in the direction of the pin axis, and a greasing port is provided at the end of the pin, and an oil passage is connected between the greasing port and the spacer chamber. When the pin is installed, the spacer piston can be pressed against the end face of the bracket member by the grease pressure from the greasing port, and the bushing member with a collar can be slid inward of the boss member along the outer circumference of the pin. A pin coupling device characterized in that it is configured to be movable.
