According to the first characteristic configuration of the present invention, as the slide mechanism, a wedge shape that secures a reaction force to the box body and guides the holding portion into a contact state by causing the inclined wedge surface to enter the sliding portion while being in sliding contact with the holding portion. Since the member and the pressure receiving surface that is formed on the holding portion and receives the inclined wedge surface in a state of contact with the surface, the contact state between the inclined wedge surface of the wedge-shaped member and the pressure receiving surface of the holding portion is determined. The terminal can be connected by sliding the wedge-shaped member while maintaining it.
Therefore, since the operation of the slide mechanism can be transmitted in a state in which the operating force is distributed over the entire wide contact surface as compared with the conventional one in which the operation of the slide mechanism is performed only by point contact between the rod member and the inner periphery of the elongated hole, The holding portion can be slid smoothly.
