Patent ID: 7855479

Claim:
A noise suppression structure of a blower motor, comprising: a bottomed, substantially cylindrical-shaped end bracket member including a peripheral wall part and a bottom surface part, the peripheral wall part being provided between the bottom surface part and a housing and an end edge of the peripheral wall part being configured to be mounted to an one end opening of the housing, and the bottom surface part being integrally formed with the peripheral wall part, rotatably supporting one end of a motor rotary shaft part and covering the one end opening of the housing; a connector part disposed in the end bracket member, provided in the peripheral wall part, and to which electric power is externally supplied; a metal terminal member provided in the end bracket member, coupled to the connector part, and including an extension part being extendedly provided along the bottom surface part in a circumferential direction of the bottom surface part and having a connection part; a brush member provided in the end bracket member and opposing a commutator mounted to the motor rotary shaft part; and a noise reduction member disposed in the end bracket member in a position opposite to a side of the peripheral wall part to which the connector part is provided, and inserted between the metal terminal member and the brush member to be connected with the connection part of the extension part of the metal terminal member and the brush member; wherein the noise reduction member includes a choke coil; wherein the noise suppression structure of the blower motor further comprises a guide member having guide side walls extending in a direction from the bottom surface part toward an inside part of the blower motor, wherein the guide side walls which extend in the direction from the bottom surface part toward the inside part of the blower motor are configured: to guide a conductor of the choke coil of the noise reduction member along the bottom surface part in the circumferential direction of the bottom surface part, and to slide and guide the metal terminal member to mount the metal terminal member to the connector part from the inside part of the blower motor.
