In particular, the first flange member 11 and the second flange member 12 positioned at the upper end and the lower end of the base frame 1 are formed on the housing convex portion 32 on the inner side of the top plate of the cabinet 30 and the housing convex portion 33 on the bottom plate. Since it is locked, the closing property of the edge part of the upper part of the front door 31 and a lower part can be improved. Therefore, when an unauthorized tool such as a bar is inserted between the upper edge or the lower edge of the cabinet 30 and the front door 31 and the force is opened forcibly, the gap is difficult to spread, and unauthorized unlocking is effectively performed. Can be prevented. Moreover, since each hook member 11-14 tilts independently, even if it inserts a wire etc. in the clearance gap of the front door 31, and hooks any one hook member with a wire etc. and tilts it in the unlocking direction, The other hook member does not move in the unlocking direction, and this type of unauthorized unlocking can be prevented.

  When the front door 31 is unlocked, the lock shaft 7a of the cylinder lock 7 is rotated by the key, and the cam member 8 is rotated counterclockwise in FIG. As a result, the first engaging convex portion 8a of the cam member 8 engages with the engaging portion 15c of the first unlocking operating rod 15 and slides downward, and at the same time, the second engaging convex portion of the cam member 8 The part 8b engages with the engaging part 16c of the second unlocking operating rod 16 and slides it upward.

  At this time, the cam member 8 is located on a diagonal line in which the first engaging convex portion 8a and the second engaging convex portion 8b pass through the center of the cam. 2 The load for sliding the unlocking operation rod 16 acts in a balanced manner, and the first unlocking operation rod 15 and the second unlocking operation rod 16 can be slid in the unlocking direction with a relatively light force. .

  During the unlocking operation, the first unlocking operating rod 15 slides downward, the second unlocking operating rod 16 slides upward, and the first and third hook members 11 and 13 tilt downward. Then, the second flange member 12 and the fourth flange member 14 tilt upward. By the tilting of the four first to fourth collar members 11 to 14, the engagement between the housing convex portion 32 and the housing convex portion 33 of the cabinet 30 and the locking portions 22 and 23 of the receiving metal fitting 21 are performed. Is disengaged, and the front door 31 becomes openable.
