In a brake mechanism (110) for a traction machine, a plurality of braking members (20) are arranged so as to face to an internal wall of a bowl-shaped portion (12) of a brake drum (2) whose one surface is open. An elastic member (30) is provided which is connected to each of the braking members (20) and is arranged so that an elastic force acts in a radial direction from the center of the bowl-shaped portion (12) and in the direction such that the braking member (20) is pressed on the internal wall of the bowl-shaped portion. Also, the brake mechanism (110) includes a supporting member (8) for fixing a portion of the elastic member (30), the portion being opposite to a portion in which the elastic member (30) is connected to the braking member (20), and a control mechanism (42, 50) for controlling the elastic force by generating a resisting force opposing to the elastic force. <IMAGE> |
