Abstract
A gear side feeding terminal (73U, 73V, 73W) connected to a motor side feeding terminal (36U, 36V, 36W) provided to the end portion of a stator (32) in the axial direction of the stator (32) from the axial direction of a rotor (38) is provided on a control board (70) for controlling the rotor (38), housed in a gear case (61) so as to be stacked on a speed reduction mechanism (SD) from the direction crossing the axial direction of the rotor (38). In this manner, the wiper motor is composed of a brushless wiper motor (20), and it is unnecessary to provide the gear side feeding terminal (73U, 73V, 73W) so as to avoid the control board (70). Accordingly, it is possible to prevent electric noises, and provide a wiper motor reduced in size and weight, and since it is unnecessary to form a clearance in the control board (70), it is possible to provide a wiper motor further improved in degree of freedom for designing the control board (70).
