Miniature motor with brush pieces forming different angles with commutator

A minature motor comprising:

• a housing including a bottomed hollow cylindrical member defining an inner circumferential surface;
• a permanent magnet fixedly fitted to said inner circumferential surface of said housing;
• an end plate engaged with an open end of said housing;
• a rotor rotatably supported by bearings provided on said housing and said end plate;
• a commutator connected to said rotor;
• brush means for providing power to said commutator, said brush means including a plurality of brush pieces, each of said brush pieces including a brush intermediate part extending in a brush piece longitudinal direction and a brush tip with bent portion defining a V-shape providing open legs, each tip of said each of said brush pieces making contact along a tangential line with respect to said commutator wherein said tangential line of each tip is different from an adjacent tip with one tangential line at a first angle with respect to said longitudinal direction and another tangential line at a second angle with respect to said longitudinal direction, said first and second angles being in different directions with respect to said longitudinal direction wherein each tip of said brush pieces has sides disposed at a different angle with respect to said line extending in said longitudinal direction as compared to adjacent tip.
