Abstract (en)
Provided is a brake release mechanism capable of reducing effort required for a brake releasing operation. The brake release mechanism includes amovable lever (13) and a fixed lever (15) provided so as to be rotatable relative to each other, and a plurality of rolling bodies (17) provided between the levers. On one surface (13a) of a pair of surfaces of the levers which face each other, a plurality of supporting holes (19) are formed, and on another surface (15a) thereof, a plurality of elongated holes (21) each extending in an arc-like manner so as to enable the rolling bodies to move while rolling are formed. Each of the elongated holes is formed so that a depth for housing a corresponding one of the rolling bodies changes when the rolling bodies move along the elongated holes. A distance between both the levers in a direction of a relative rotation axis changes in accordance with the relative rotation of the levers. The brake release mechanism further includes a release bolt (43) which avoids securing a position of the fixed lever in the direction of the relative rotation axis and secures a position of the movable lever in the direction of the relative rotation axis. Through the rotation of the movable lever, the fixed lever applies a traveling force to a movable body in the direction of the relative rotation axis, to thereby release a brake.
