PURPOSE:To prevent the stop part of a stopper fixed to the housing from being engaged again with a cover when the operation for pushing the stopper is released. CONSTITUTION:A stopper 17 is provided with a stop part 25 being engaged with an engaging part 38, and an operating part 18 for disengaging the stop part 25 and the engaging part 38 upon pushing into a box body 11. The stopper 17 is provided with a part 20 which comes into contact with the engaging part 38 when the operating part 18 is pushed into the box body 11 and pushes a cover 12 against the box body 11 to open the cover 12. Since the cover 12 is pushed against the box body 11 and opened when the operating part 18 is pushed, the stop part 25 is not engaged again with the engaging part 38 even it the pushing operation of the operating part 18 is released. |
