Abstract
Components of a jig are suppressed from coming into contact with a pin hole when a coupling pin is removed from the pin hole, and a length of the jig in a coupling pin axial direction is held down. A coupling pin attaching/detaching apparatus (a coupling pin extracting apparatus) includes a cylinder and a connection member. The cylinder is arranged outside a coupling pin in a radial direction of the coupling pin and is extensible. The connection member is connected to the coupling pin and the cylinder. Extension of the cylinder causes the coupling pin to be extracted from a pin hole via the connection member.
