<P>PROBLEM TO BE SOLVED: To achieve brake releasing of a shutter opening/closing machine more excellently and stably even in application to a plurality of types of opening/closing machines having different configurations (especially, projection lengths of brake release levers from casings of the shutter opening/closing machines). <P>SOLUTION: A brake release mechanism includes a casing having a surface part 8A close to an opening/closing machine 5, a long hole 80a which is formed in the surface part 8A and has a length allowing a brake release lever 50 of the opening/closing machine 5 to be displaced, and a brake release body 84 which is positioned in the casing, and provided movably in a length direction of the long hole 80a, the brake release body 84 includes an abutting part 8421 which projects into the long hole 80a, and the abutting part 8421 moves while projecting into the long hole 80a, abuts against the brake release lever 50 received in the long hole 80a from outside the casing, and displaces the brake release lever 50 to release a brake of the opening/closing machine 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
