By ensuring a long distance between the mating end surface and the link plate that supports the power transmission block closest to the mating end surface, and utilizing the flexure of the power transmission block portion, the power can be transmitted closest to the mating end surface. It is characterized by reducing the load on the link plate that supports the transmission block.
