It is also rotatably supported by a ball bearing 5 fixed to the trunk casing 4. A spline 6 that meshes with a gear of a reduction gear device is provided at the tip of the rotating shaft on the one end side that protrudes into the reducer housing beyond the corresponding ball bearing. A brake barrel 8 equipped with a centrifugal speed governor 7 is integrally fixed to the rotating shaft on the other end side that protrudes into the brake barrel housing by using a key. Reference numeral 10 denotes two through bolts provided parallel to the rotating shaft at an interval, and the electric motor is sandwiched between the bolts and the two casings are fixed together, so that the two casings are integrated into one body. A box-shaped base 9 with an open bottom plate portion is fixed to the lower side thereof. A limit switch device 12 and a brake device 14 are attached to the lower surface of the top plate portion of the base using screws, respectively. A gear 11 that meshes with the gear of the gear device is provided through the opening, and the brake device 1
4 is provided with a brake piece 13 that slides into contact with the brake cylinder from the outside through corresponding openings provided in the base and the brake cylinder housing.
