STRUCTURE FOR MOUNTING LOCK DEVICE

PROBLEM TO BE SOLVED: To easily produce a bracket which is capable of preventing a lock device from protruding from a side face of a frame side and has sufficient rigidity.SOLUTION: A mounting structure of a lock device includes a bracket 4, 5 and a lock device 50. The bracket 4, 5 includes: a frame side 2a; frame-side fixing parts 12, 15 which are mounted to a frame side 2a at an edge of a lock device protruding opening 25; lock-device-side fixing parts 11, 14 which are provided away from the frame-side fixing parts 12, 15; and a connection supporting part 13, 16 which connects the lock-device-side fixing parts 11, 14 and the frame-side fixing parts 12, 15. The brackets 4, 5 are mounted to upper and lower ends of the lock device protruding opening 25, respectively. The lock device 50 includes a lock case 55, and lock device mounting pieces 51, 52 which can be mounted to the lock-device-side fixing parts 11, 14. The brackets 4, 5 are formed by separating the lock-device-side fixing parts 11, 14 with respect to the frame-side fixing parts 12, 15 in such a manner that the lock device mounting pieces 51, 52 can form a plane inside of a side face of the frame side 2a or the approximately same as the side face.
