PROBLEM TO BE SOLVED: To enable the rotary inspection of a hinge device before the installation by eliminating the rotary friction by a hinge lock mechanism. SOLUTION: A tongue 5 at a front end of a spring member 4 fixed to a holder 2 of the hinge device is put out of a groove 6 installed in a casing 3, and a shaft 1 is penetrated into the casing 3 and the holder 2 to be rotatably fitted. The rotary inspection of the hinge device before the installation can be carried out because of free rotation in this state. Since the tongue 5 is engaged with the groove 6 installed in the casing 3 to assemble so that the casing 3 and the holder 2 are locked so as not to relatively rotate, it easily enables the positioning with a hinge receiver of the casing at assembly. The hinge device in locked state is inserted into the casing, a contact part 7 is pressed against the casing to remove the tongue 5 from the groove 6, and the locking is released so that it can relatively and freely rotate. Since the spring member 4 is not involved in the rotation, there is no rotation friction in the hinge lock mechanism. COPYRIGHT: (C)2006,JPO&NCIPI
