PROBLEM TO BE SOLVED: To provide a thin hoisting machine for an elevator capable of easily obtaining required braking release action by an electromagnet mechanism in a braking machine. SOLUTION: A housing 1 and a stator winding of an electric motor are integrated, and a rotary body 6 constituting the electric motor and a drive sheave are integrated. A movable iron core 16 of the braking machine 12 operates in the longitudinal direction of a shaft 4 to transmit its displacement to a braking shoe 22 through operation of an L-shaped operation piece 19. Consequently, a suction area for obtaining a suction force of the electromagnet mechanism 17 for operation of the braking shoe 22 can be ensured, and depth of a recessed part 5 of the rotary body 6 is reduced to make the hoisting machine thin further. For this reason, an installation space for the hoisting machine is further reduced to save and reduce a hoistway space to facilitate the installation of the elevator and reduce construction cost for a hoistway.
