A force multiplying member (30) is mounted rotatably on supports of a first housing (10) and is guided slidably relative to the first housing (10). In a connecting process of the two housings (10, 20), the force multiplying member (30) successively performs a rotational movement that displays a force multiplying action by causing tracks (39) for rotational movement and cam followers (23) to slide and a sliding movement that displays a force multiplying action by causing tracks (40) for sliding movement and the cam followers (23) to slide.
