と、扉が開放されてケース内の高圧ガスが噴出するとと
もに、その高圧ガスとともに構造部品が飛出して、人
的、物的被害のおそれがあり、きわめて危険である。[Problems to be solved by the invention] However, since the lock piece is supported by only one shaft, if the internal pressure of the case rises due to, for example, an internal short circuit, the shaft and other parts are destroyed by the load applied to the door. There was a risk of being. When the lock is broken in this way, the door is opened and high-pressure gas in the case is ejected, and structural parts are ejected together with the high-pressure gas, which may cause human or property damage. It is a danger.
又、前記軸を太くすると、扉の外側面においてその軸の
端部に形成されるキー操作部が太くなってケースの外観
を損うものである。Further, if the shaft is thickened, the key operation portion formed at the end portion of the shaft on the outer side surface of the door becomes thick and the appearance of the case is impaired.
［課題を解決するための手段］ 以上の問題点を解決するために、この考案においては、
扉の内側面には保持部材を固着するとともに、同保持部
材には前記掛止片に対してロック片が掛止状態にあると

ことができる。Locks 3 are provided on the upper and lower ends of the open ends of the doors 2, respectively. The lock 3 and its related configuration will be described in detail below. A reinforcing plate 4 is fixed to the inner surface of the door 2, and the lock 3 is attached and fixed through the reinforcing plate 4 and the door 2. An end portion of the lock 3 on the outer side portion of the door 2 serves as an operation portion 5 for opening and closing the lock 3 by using a key (not shown), and a shaft 6 at an inner end portion of the lock 3 is rotated by this key operation. It A lock piece 8 is fixed to the shaft 6 via a bracket 7. When the lock piece 8 is locked by a locking piece 9 fixed to the case body 1 as the shaft 6 rotates, the lock piece 8 is positioned. The door 2 is moved to a position away from it, and the door 2 is locked so that it cannot be opened at the hooking position. The locking portion of the lock piece 8 and the lock piece 9 is a contact plate 10.
It is composed by. A spacer 11 is interposed between the bracket 7 and the lock piece 8, and the spacer 11 can be locked by selecting an appropriate thickness or an appropriate number of spacers, and further by adjusting the thickness of the contact plate 10. The positional relationship between the piece 8 and the hooking piece 9 can be adjusted to an appropriate one.

側から保持される。The holding member 15 is provided on the inner surface of the door 2 in the vicinity of the lock 3.
Is fixed, and a holding groove 16 into which the lock piece 8 that has been rotated in the locking direction enters is formed in the holding member 15, and the protrusion 17 on the side surface of the lock piece 8 at the entry position.
Is brought into contact with the inner end surface of the holding groove 16 and its position is regulated. 18
Is a holding piece formed by providing a holding groove 16 in the holding member 15. Then, when the lock piece 8 enters the lock piece 8, the back surface of the lock piece 8 is held by the holding piece 18 from the opposite side of the door 2.
従って、内部短絡等により内圧が急上昇したりした場

め、扉２の外面に表われる操作部５が大きくなることは
なく、外観が損われるおそれはない。Therefore, when the internal pressure suddenly rises due to an internal short circuit or the like, a large force is applied to the door 2 in the outward opening direction, and a force in the direction away from the door 2 is applied to the lock piece 8, which force is strong. In this case, the part between the lock piece 8 and the shaft 6 may be destroyed, the door may be opened, and the parts and the like in the case body 1 may fly out violently, causing human and physical damage. Since the lock piece 8 is held from the rear surface thereof, the lock piece 8 is opened between the door 2 and the lock piece 8 and the shaft 6.
There is no fear that the portion between the door and the like will be destroyed, the opening of the door 2 can be prevented, and the safety is excellent. Further, since the breakage of the lock 3 can be prevented without increasing the size as described above, the operating portion 5 appearing on the outer surface of the door 2 does not become large and the appearance is not damaged.
