The present invention relates to a friction washer for preventing sintered bearing oil from being scattered. In particular, a plurality of circular blocking films is formed on one cross section of a body corresponding to the sintered bearing. Therefore, the apparatus can prevent oil, impregnated in the sintered bearing, from being scattered while preventing the oil in the sintered bearing from flowing from the surface of the friction washer to a commutator. The friction washer, for preventing sintered bearing oil from being scattered, is installed between the commutator in a motor and the sintered bearing; reduces friction between the commutator and the sintered bearing, and vertical vibrations of the commutator; and thus extends the life span of the motor. |
