To provide a vehicular component member capable of suppressing the degradation of a ground contact property of a tire and ride quality caused by an increase of an unsprung mass, in a vehicle with an in-wheel motor mounted therein.

Teeth 31, 31A and 31B are embedded in a case 20 of an in-wheel motor 3 from the outside of a vehicle. A stator coil 30A (30B) is coiled around the teeth 31A(31B) arranged in the vertical direction. A coil spring 36 (38) is mounted between the tip of the tooth 31A (31B) and the lower side of the stator coil 30A (30B), and a coil spring 37 (38) is mounted between a base of the tooth 31A (31B) and the upper side of the stator coil 30A(30B).
