FASTENING DEVICE FOR RAIL-INSTALLED APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a fastening device for a rail-installed apparatus wherein it is unnecessary to manufacture a movable lug separately from the casing of an apparatus and no spring is required. SOLUTION: The fastening device is for a rail-installed apparatus provided with a rail 1 installed on equipment and on the casing 2 of the apparatus with a pair of lugs 5 and 6 fit onto an overhang of the rail 1. In the fastening device for the rail-installed apparatus, the casing 2 of the apparatus is made of flexible synthetic resin. One of the pair of the lugs 5 and 6 is a shape-fixed lug 5 hard to deform, and the other is a movable lug 6 in such a shape that the movable lug can be deformed in the direction of overhanging of the overhang of the rail 1. A hook 8 is formed for externally deforming the movable lug 6. A hollow portion 7a is formed in the movable lug formation portion 7 and a connecting portion 9 to be fit into the hollow portion 7a of the movable lug formation portion 7 of the casing of the adjoining apparatus coupled with the rail 1 is connected to the movable lug formation portion 7.
