Patent ID: 7385327

Claim:
A motor actuator structured such that a coupler provided with a motor accommodating hole and terminals is integrally formed within a motor case, a motor is arranged so as to be accommodated within said motor accommodating hole, and flat base plates extending to an outer side from an outer periphery of the motor are electrically connected to said terminals, wherein the motor accommodating hole ( 2 ) formed within said motor case is formed by a pressure insertion hole ( 2 a ), which is formed at the side of a bottom portion ( 1 a ) of the motor case ( 1 ) and formed so as to have a smaller diameter than the outer periphery ( 3 a ) of the motor ( 3 ), and an insertion hole ( 2 b ), which is continuously provided at the side of opening ( 1 c ) of the motor case ( 1 ) from the pressure insertion hole ( 2 a ) and formed so as to have a larger diameter than the outer periphery ( 3 a ) of the motor ( 3 ), wherein the terminals ( 5 , 6 ) formed in the coupler ( 4 ) are arranged in parallel to a longitudinal axis (X-X) of the motor accommodating hole ( 2 ) and is arranged so as to protrude toward the opening portion ( 1 c ) of the motor case ( 1 ), and wherein the flat base plates ( 7 , 8 ) connected to a coil of the motor ( 3 ) are arranged so as to protrude sideward from the outer periphery ( 3 a ) of the motor ( 3 ) while being orthogonal to a longitudinal axis (Y-Y) of the motor ( 3 ), and wherein, the terminals ( 5 , 6 ) are arranged so as to be inserted into the connection holes ( 7 a , 8 a ) provided in the flat base plates ( 7 , 8 ) in a free state that an insertion side bottom portion ( 3 c ) of said motor is inserted into the insertion hole ( 2 b ) of the motor accommodating hole ( 2 ) from the opening portion ( 1 c ) of the motor case ( 1 ) so as to form a gap (S) between the outer periphery ( 3 a ) of the motor ( 3 ) and the insertion hole ( 2 b ), and the insertion side bottom portion ( 3 c ) of the motor ( 3 ) is pressure-inserted toward the pressure insertion hole ( 2 a ) of the motor accommodating hole ( 2 ) in a state that the terminals ( 5 , 6 ) are inserted to the flat base plates ( 7 , 8 ), whereby the outer periphery ( 3 a ) of the motor ( 3 ) is fixedly arranged in the pressure insertion hole ( 2 a ).
