As shown in FIG. 14, conventionally (especially the housing mounting structure shown in Patent Document 2), when the cover member 2 is removed from the base 1, the distance between the pressing force point 50 and the fulcrum 52 is the cover. Since the distance between the action point 51 and the fulcrum 52 where the member 2 and the base 1 are engaged is smaller and the distance between the force point 50 and the action point 51 is separated, a large force is applied to the force point 50. Otherwise, the action point 51 cannot be disengaged. However, in the present invention, since the pressing portion 2t is formed on the edge surface of the cover member 2 at a position corresponding to the cover member-side engagement protrusion 2f, as shown in FIG. 14, the force point that is the place where the elastic portion 2m is pressed. 56, and the action point 56 where the engaging piece 2j and the engaging portion 1u are engaged are configured at almost the same position, so that the engaging portion 55 does not require a large force as compared with the conventional case. Can be disengaged. In the present invention, the fulcrum 57 is the base end of the elastic part 2m. When the elastic part 2m is pressed, the elastic part 2m bends inward with the base end of the elastic part 2m being the fulcrum 57 as a base point. ing.
