Abstract: A stopper mechanism includes: an arm part which is a part of a cover; an arc-like projection part at the end of the arm part; and a sliding member slidably provided in the cover. When the sliding member flanks the projection part, the arm part is prevented thereby from being bent and a stopper mechanism is locked. When the sliding member is allowed to slide and to be removed from behind the projection part, the arm part is allowed to be bent, and the stopper mechanism is unlocked.
