  • Patent number: 11183904
    Abstract: A motor includes a motor body, a speed reduction unit, a brush holder, and a circuit board. The motor body rotationally drives a rotation shaft. The speed reduction unit reduces speed of rotation of the rotation shaft. The brush holder is held by a motor case of the motor body and a gear housing of the speed reduction unit. The circuit board is arranged in a board receptacle that is open in a direction orthogonal to a motor flattened surface. The brush holder includes a terminal that is directly and electrically connected to the circuit board.
