A bushing is fitted in a lower end portion of a cylindrical hole of a pin tip having the cylindrical hole opened at a lower end side, and the bushing is vertically movably inserted onto the small diameter portion of the pin. A stopper portion for retaining the bushing is provided at a front end of the small diameter portion.
