<P>PROBLEM TO BE SOLVED: To provide an auxiliary machine for a vehicle capable of suppressing the shortening of the life of a bearing accompanied by the deformation of an outer ring raceway surface of the bearing. Ž<P>SOLUTION: In an alternating current generator 100 for the vehicle provided with a front side frame 1 for holding the bearing 15 for rotatably supporting a rotation shaft 14 in which a pulley 19 attached to the rotation shaft 14 rotatively driven by a belt 110, the front side frame 1 has a bearing storing part 7 having an inner circumferential surface facing an outer circumferential surface of an outer ring 15a of the bearing 15 and a clearance between the inner circumferential surface of the bearing storing part 7 and the outer circumferential surface of the outer ring 15a or a fastening margin is irregular along a circumferential direction.
