PURPOSE: A motor for a vehicle is provided to be capable of reducing the resonance of a brush holder and preventing chattering noise(brush noise) being transferred to a housing. CONSTITUTION: The motor has a pair of friction washers(8a,8b) inserted onto its armature shaft(S) for reducing the vibration of sintered bearings(5a,5b) supporting the armature shaft and preventing oil from being sprayed. Each friction washer(8a) has a circular dish shaped extension surrounding a respective bearing, and protrusions(80) received in grooves associated with the shaft(S) or with a commutator(4) carried thereby. The use of such friction washers reduces the number of parts in the motor and prevents slippage whereby the thrust gap is maintained. A brush holder stay(31), to which a brush holder(30) is fixed, is fixed to the motor housing(1) by way of a rubber damper(9).
