Beschreibung
Zusammenfassung:	A linear motion device includes: a bearing mounted to the outer periphery of a ball screw; a nut holder through which the ball screw passes; and a bearing pressing member which is fixed to a motor housing with the ball screw inserted in a through hole and which restricts the movement of the bearing in the motor housing in the axial direction. The bearing pressing member has a cutout portion extending from the inner peripheral surface of the through hole over to the outer peripheral surface of the bearing pressing member in the radial direction.
