To provide a brake of a winding machine for an elevator in which collision sound is reduced when a braking piece 23 abuts on a rotary body 9.

A braking piece 23 is attached to a first moving-iron 21, a first elastic body 24 presses the braking piece 23 onto the rotary body 9 through the first moving-iron 21 to generate a braking force, a second elastic body 26 presses the braking piece 23 with a pressing force smaller than the first elastic body 24 through a second moving-iron 25 separated from the first moving-iron 21. Based on a start instruction of the elevator, an electromagnet is energized so that pressing of the braking piece 23 by the first elastic body 24 and the second elastic body 26 is released to open a winding machine 1. When a stop instruction of the elevator is issued, energization of the electromagnet 27 is stepwise reduced chronologically, thereby individually operating the first moving-iron 21 and the second moving-iron 25.
