Patent ID: 8242648

Claim:
A control circuit member provided in a motor including a motor main body having a rotary shaft and a gear housing, which is integrated with the motor main body and accommodates a reduction gear for reducing rotation speed of the rotary shaft, the control circuit member comprising: a circuit substrate, which is accommodated in a circuit accommodating portion provided in the gear housing; a rotation detecting element mounted on the circuit substrate, the rotation detecting element being arranged to face a detector magnet that is provided on and rotate integrally with the rotary shaft; and a substrate support member for supporting the circuit substrate in the circuit accommodating portion; wherein the control circuit member is configured to be insertable into the circuit accommodating portion along an insertion direction parallel to the axial direction of the rotary shaft, wherein the circuit substrate is configured to be arrangeable inside the circuit accommodating portion while being inclined with respect to the axial direction of the rotary shaft, so as to cause the rotation detecting element to approach the detector magnet, wherein the substrate support member includes a substrate attaching portion, which extends in a direction perpendicular to the axial direction of the rotary shaft, the substrate attaching portion has a distal end surface, which is inclined with respect to the axial direction of the rotary shaft so as to be in surface contact with an surface of the circuit substrate in a state where the circuit substrate is assembled to the substrate support member while being inclined with respect to the substrate attaching portion.
