摘要:
In a ball screw device, a ball screw linear-movement member is screwed with a ball screw rotary member and configured to linearly move in accordance with a relative rotation with the ball screw rotary member. A housing is holding the ball screw rotary member. A motor is disposed in a motor chamber of the housing, and configured to rotate the ball screw rotary member with a rotor coupled to the ball screw rotary member. A stopper is configured to collide with a brake when an amount of a relative linear movement between the ball screw rotary member and the ball screw linear-movement member becomes no less than a prescribed amount. The brake is configured to decelerate rotation of the rotor by the collision of the stopper with respect to the brake.
