Therefore, there is no obstacle above the flange 15 connected to the upper end of the lock pin 14, and the lock pin 14 can freely move up and down. Therefore, when the door 2B is opened and closed, the inclined contact surfaces 17a and 17b in the contact portion 17 of the engaging member 1B pass while pushing up the lock pin 14, so that the lock pin 14 opens and closes the door 2B. The door 2B can be freely opened and closed without hindering operation.

  On the other hand, when the cabinet 2 is shaken with the occurrence of the earthquake, as shown in FIG. 12A, at least one steel ball 16 out of the three steel balls 16 retracted in each retreat space. Rolls on the flange 15 to prevent the lock pin 14 from rising, as shown in FIG. 5B, even if the door 2B is opened, the engagement member 1B attached to the door 2B The contact portion 17 is locked to the lock pin 14, and the door 2B hardly opens. Here, when the shaking of the cabinet 2 due to the earthquake stops, the steel ball 16 located on the flange 15 rolls the inclined upper surface of the flange 15 to the peripheral side as shown in FIG. Since it will return to the evacuation space, it will be in the state which can open and close the door 2B freely, as shown to Fig.11 (a)-(c).
