えたところの牽引補助具。 A towing aid that connects the towing vehicle with the handcart by providing a connecting member at one end that is pivotally connected to the towing tool of the towing vehicle, and a locking member that locks the towing hook of the handcart at the other end. The locking member includes a towing hook gripping portion with one side open, and an opening/closing claw for opening and closing the opening of the towing hook gripping portion, and the opening/closing claw is linked at a base end to the opening claw. , the operating rod whose tip extends obliquely upward toward the connecting member can be opened and closed in conjunction with the advancing and retracting operations, and the operating rod acts in a direction to reverse an appropriate portion thereof with respect to the connecting member side. It is supported by the support member and is biased by the bias member that biases in the opposite direction to the acting force of the support member, and when the opening opening is closed by the opening/closing claw, the direction of the locking member at the support point is A traction aid that is equipped with a stopper that prevents it from moving.
