摘要： The axial direction of a worm wheel is defined as a motor short-transverse direction, and a plane orthogonal to the motor short-transverse direction is defined as a motor flat plane. An imaginary plane contacting a first end of a sensor magnet in a motor short-transverse direction and parallel with the flat plane is defined as a first imaginary plane. An imaginary plane contacting a second end of the sensor magnet in the motor short-transverse direction and parallel with the flat plane is defined as a second imaginary plane. A control circuit board is provided with a rotation detecting element that detects rotation of the rotary shaft of the motor. The control circuit board is arranged to be parallel with or inclined relative to the flat plane, and is provided between the first and second imaginary planes.
