Task It is towing surely without leaving the balance. Solution The rotational motion of the motor 32 is converted into the reciprocating motion in the vertical direction of the moving plate 62 through the roller cam 60, and based on the reciprocating motion in the vertical direction of the moving plate 62. The pair of hook levers 26a and 26b are rotated. By the rotation of the pair of hook levers 26a and 26b, the hook levers 26a and 26b are brought into either a state where engagement with the frame 92 of the trolley 90 and a state where engagement is avoided. Moreover, the spring force of the coil spring CS acts on the pair of hook levers 26a and 26b through the moving plate 62, and the hook levers 26a and 26b are framed in the state which was urged by the said spring force. It is associated with (92). Thereby, even when the up-down direction vibration generate | occur | produces in the unmanned carrier 1 and the trolley | bogie 90, the release | release of engagement with the frame 92 of a pair of hook lever 26a, 26b can be prevented favorably.
