PROBLEM TO BE SOLVED: To provide a hoisting machine of an elevator capable of coping with different directions of installation by the same equipment. SOLUTION: This hoisting machine 5 is provided with a brake drum 14 constituted by arranging an electric motor 6, a sheave 8, and a brake 10 linearly and connecting the brake 10 with the electric motor 6, braking arms 16a, 16b having braking pieces 15a, 15b abutted on the brake drum 14 and rotated and supported, braking springs 18a, 18b for pressing the braking pieces 15a, 15b against the brake drum 14, and braking release means 20a, 20b for driving the braking arms 16a, 16b. A substantially L-shaped surface of projection is formed by the electric motor 6 and the braking arms 16a, 16b, the braking release means 20a, 20b are provided in parallel with the electric motor 6 along the direction of extension of the braking arms 16a, 16b, and height of the brake 10 is less than height of the electric motor 6. The electric motor 6 and the brake 10 are rotated in any direction by 180 degrees by using an output shaft 9 of the electric motor 6 as an axis for use. COPYRIGHT: (C)2008,JPO&INPIT
