Abstract
This electric braking device transmits power generated by an electric motor to a pressing member and causes pressing force to be generated by the pressing member with respect to a friction member. The electric braking device includes a lock mechanism. A locked state (in which movement of a locked section in a direction in which pressing force decreases is impossible) is achieved in the lock mechanism by: performing 'supplied power amount reduction control' in which the amount of power supplied to the electric motor is reduced while a locking member is maintained in a lockable position; causing the locked section to move in the direction in which pressing force decreases; and causing the locking member and the locked section to engage. When performing supplied power amount reduction control, the amount of power supplied is first reduced by a large reduction gradient and then reduced by a small reduction gradient.
