Abstract

A work implement includes a ground engaging tool with a first through-hole, an adapter with a second through-hole, a retaining pin, a metal bushing and a metal retainer. The retaining pin is inserted into the first and second through-holes disposed in a state in which the ground engaging tool is in contact with the adapter. The retaining pin is inserted in an inside of an cylindrical member of the bushing, which is disposed at an end portion of the retaining pin inside the first through-hole. The metal retainer prevents the bushing from coming loose from the retaining pin by sandwiching the bushing between the metal retainer and the adapter at the end of the retaining pin. The bushing is disposed in a state that allows movement in an axial direction of the retaining pin between the adapter and the retainer on an outer peripheral face of the retaining pin.
