Abstract
In a structure where the lid portion is mounted on the main housing body comprising apertures and in such a manner as to turn freely thereon, the concave lock portion and the locking protrusion adjacent thereto capable of locking the lid in the closed state are located in the aperture side of the main housing body. The lid portion is provided with the hooking piece comprising the spring portion and the arc-shaped protrusion. When the lid portion turns to open or close the aperture portion, the arc-shaped protrusion comes into contact with the locking protrusion under pressure with the spring portion, in order that a force opposing to the turning direction may be applied thereto before and after it passes through the locking protrusion, to keep the lid portion in two states i.e. the open state and the closed state.
