PURPOSE: An ABS motor for a vehicle is provided to reduce costs by applying one concentric bearing. CONSTITUTION: An eccentric bearing(12) is inserted into a concentric part(11b) formed on the lower side of an axis(11). A concentric bearing(13) is inserted into an eccentric part formed on the upper side of the axis. A separation preventing member prevents the separation of the eccentric bearing and the concentric bearing from the axis. The axis rotates with a motor unit(10). The eccentric bearing inserted into the concentric part is eccentrically rotated according to the rotation of the axis. A plunger of a return pump moves by the eccentric rotation of the concentric bearing and the eccentric bearing.
