- the distance between the movable lever 13 increases and the movable lever 13 is allowed to rotate relative to the relative rotation axis CL (particularly in the direction away from the fixed base 5). It is limited by the release bolt 43. Therefore, an increase in the distance between the movable lever 13 and the fixed lever 15 appears as a movement in the direction of the relative rotation axis CL in a direction in which the fixed lever 15 is separated from the movable lever 13.
- the movable body 3 receives a pressing force in the direction of the relative rotation axis CL from the fixed lever 15 and moves so as to approach the fixed base 5 against the elastic force of the elastic body 11. Thereby, the movable body 3 is integrated with the movable body 3.
- the brake shoe 9 provided as a result is separated from the inner peripheral surface of the rotor 7 to achieve manual release of the brake.
- the relative movement between the movable lever 13 and the fixed lever 15 is ensured appropriately by setting the collar 39 as follows.
- the height of the collar 39 is X
- the depth of the support hole 19 of the movable lever 13 is a
- the thickness of the movable lever 13 is b
- the movable body 3 necessary for releasing the brake is
- the moving distance is g, g + d ⁇ Xmin ⁇ a ⁇ X ⁇ (d ⁇ Xmax) + b ⁇ (d / 2) It is appropriate to set so as to satisfy.
- the distance between the movable lever 13 and the fixed lever 15 can be changed so that the movable lever 13 and the fixed lever 15 do not interfere during the brake release operation. Even in a state where the distance from the roller 15 is maximized, it is possible to prevent the rolling elements 17 sandwiched between the two from falling off.
- the brake release mechanism when the brake release force is applied to the movable body, it is not necessary to generate a large frictional force due to wide surface contact on the movable portion. More specifically, friction due to rotation of the movable lever can be absorbed by rotation of the rolling element itself. Thereby, the labor of manual brake release work can be greatly reduced. In addition, because the brake can be forcibly released by applying only the vertical rotational force to the hoisting machine, there is no need to provide a large space for releasing work on the side of the hoisting machine. It can be connected to the space saving of the room.
- the restraining portion restrains the position of the other relative rotation axis CL direction without restraining the position of the movable lever (first member) and the fixed lever (second member) in the relative rotation axis CL direction.
- Any device that provides a restraining action may be used. Therefore, as long as the restraint portion can provide such an action, it is not limited to being an independent single member as in the above embodiment, but may be a part of the first member or the second member, or a part of the fixed base. Or it may be part of other elements.
