Abstract
An electric brake device includes: an electric brake being configured such that a shaft is moved forward by diving of an electric motor, and the forward movement of the shaft brings the electric brake into an acting state in which brake friction members are pushed against a brake rotary body so as to suppress rotation of a wheel; and a motor controller being configured to control the electric motor, wherein through a rotation speed control on the electric motor, after the shaft reaches a set position before the electric brake comes into the acting state, the motor controller controls a forward speed of the shaft to be smaller than that before the shaft reaches the set position.
