SUPPORTING STRUCTURE FOR DOOR

PROBLEM TO BE SOLVED: To easily detach a door. SOLUTION: A bearing metal fitting 40 in which a bearing hole 44 is formed is attached on a box body 1 side. A supporting member 20 for supporting a shaft member main body 10 having a shaft part 11 inserted in the bearing hole 44 is fixed to a door 2. A coil spring for energizing the shaft member main body 10 is stored in the supporting member 20 so that the shaft part 11 is inserted and a top end part 11a of the shaft part 11 is journalled to the bearing hole 44. An operative hole 24 is formed on the supporting member 20, and the operative hole 24 is provided with a guide hole 24a formed along in a moving direction of the shaft part 11 to advance and retract the shaft part 11 in the bearing hole 44 by operating a handle 13 protruded from a side surface of the shaft part 11, and a holding hole 24b formed in a direction perpendicular to a guide hole 24a to hold the shaft part 11 against energizing force of the coil spring at a position where the shaft part 11 is left from the bearing hole 44 by operating the handle 13.
