That is, when the tip portion of the guide rod enters the receiving hole portion and a reaction force acts on the outer peripheral surface of the tip portion of the guide rod from the inner surface near the inlet of the receiving hole portion, the guide rod moves the root portion. The root portion slides in the vertical direction while rotating about the center in the vertical direction. In addition, the guide rod rotates in the horizontal direction in the horizontal plane about the root portion, and the root portion slides in the horizontal direction in the horizontal plane. Therefore, the guide rod has an inclination of the receiving hole (an inclination caused by the movable unit not being accurately positioned, and the relative positions of the movable unit and the fixed unit in the vertical and horizontal directions and their parallelism being out of a desirable state). Tilt to fit. As a result, the guide rod can be inserted into the inside of the receiving hole, and the relative positional relationship between the movable unit and the coupler mounting plate of the fixed unit is regulated to an accurate facing position.

According to the present invention, when the tip of the guide rod enters the receiving hole of the moving unit and a reaction force from the receiving hole acts, the reaction force causes the guide rod to swing around the root portion. Since the guide rod moves and slides, the guide rod can be inserted into the inside of the receiving hole by inclining so as to match the inclination of the receiving hole. Further, when the guide rod is inserted into the inside of the receiving hole, the relative positional relationship between the moving unit and the coupler mounting plate of the fixed unit is set to an accurate facing position. That is, even if an error occurs in the parallelism or relative position between the moving unit and the fixed unit, the error can be reliably and automatically absorbed. In addition, since members having the above-mentioned effects are integrated on the fixed unit side and environmental conditions are better than those of the moving unit, there is also an effect that trouble of the device hardly occurs. Moreover, since the above-described operation is automatically performed, there is an effect that a complicated operation is unnecessary.
