抜止め構造。[Scope of Claim for Utility Model Registration] In a towing pin that is vertically movably attached to a vertical pin hole provided in a connecting part at the end of the vehicle body of a construction vehicle, a stopper is horizontally supported near the lower end of the pin. A locking position in which the locking part at one end of the pin is rotatably supported by a shaft and protrudes outside the pin's outer periphery, and a retracted position in which the locking part is swung upward and retracted into the pin's outer periphery. The stopper is urged toward the locking position by its own weight, and when the stopper is in the locking position, the other end on the opposite side of the locking part is moved upward with respect to the support shaft. A towing pin retaining structure characterized in that a receiving part for receiving the pin is provided near the lower end of the pin.
