A spring and a coil are provided to connect and separate the brake wheel attached to the end of the brake shaft and the support body rotatably provided on the brake shaft, while the support body is connected to the brake wheel through a second reduction gear. In a hoist with a slow speed mechanism, which is connected to a second rotating shaft of a slow speed motor and is provided with a brake for braking the second rotating shaft, a disk portion of a movable core is disposed between the support body and a bracket that covers the first reduction gear. Arranged so as not to rotate, the inner side of a cylindrical part integral with the disc part is slidably supported in the axial direction on the brake shaft via a bearing, and the support body is supported on the outside of the cylindrical part via a bearing. A hoist with a slow speed mechanism, characterized in that the bracket is provided with a coil that attracts the movable core, and a spring that biases the coil in a direction opposite to the direction in which the coil is attracted.
