PROBLEM TO BE SOLVED: To provide a hinge device which will not be deviated by external force when a cover is in a closed position and can be attached/detached easily at the time of replacement or the like. SOLUTION: This hinge device is constituted of an engaging hole 12c which is fitted at a housing 12 and an engaging part 13a which is fitted at a cover 13 so that it may be rotatably-engaged with the engaging hole to permit the cover 13 to be oscillatably-supported around an oscillating shaft to the housing 12. The engaging part 13a is formed relatively shortly so that it may deviate from the engaging hole 12c easily when an impact is given. The engaging part 13a is also provided with a guide groove 12d which is formed at least in the vicinity of the closed position of the cover 13 in the housing 12 and has an arc shape whose center is the engaging hole, and a guide pin 13b which is formed at a prescribed distance from the engaging hole so that it may engage with the guide groove. |
