摘要： PROBLEM TO BE SOLVED: To provide a brake release device which can operate a brake individually at each braking part, and can easily release the brake by a small force.SOLUTION: The brake release device includes: a first bracket 11 which is disposed at the side of the other end of a brake spring 5a having one end thereof locked and urging a brake lever by the other end, and resists an urging force of the brake spring 5a; a second bracket 12 which is disposed at the side of the one end of the brake spring 5a, and faces the first bracket 11; a support 13 which fixes a distance between the first and second brackets; and an actuator 14 which is attached to the second bracket 12, and has a movable part 14b movable in the direction of making the first bracket 11 and second bracket face each other. The brake release device makes the brake spring 5a sandwiched between the first bracket 11 and the movable part 14b, and brings the movable part 14b closer to the first bracket 11 to compress the brake spring 5a.
