An elevator hoisting machine includes a first rotary part having a sheave, a brake-side end plate, and a brake disk integrally formed together, a second rotary part having a rotor with a permanent magnet and a motor-side end plate integrally formed together, wherein the second rotary part is coaxially coupled to the first rotary part with the sheave abutting on the rotor. A sheave casing serves to cover the first rotary part and support the inner periphery of the brake-side end plate, and includes a brake main body which makes contact with the brake disk body to provide braking. A frame serves to covers the second rotary part and support the inner periphery of the motor-side end plate, and includes a stator arranged to face the permanent magnet. The sheave casing and frame are coupled together to form an external enclosure.
