PROBLEM TO BE SOLVED: To provide a motor device having a connector unit and a brush holder housed individually in a casing, which can improve positioning accuracy of the brush holder in the casing and improve yield.SOLUTION: A positioning concave portion 71d is formed near an end along a housing direction in which a brush holder 70 is housed in a gear case 31. A positioning protrusion 34f for positioning the brush holder 70 in a proper position of the gear case 31 is arranged in the gear case 31 in engagement with the positioning concave portion 71d. A connector unit 50 and the brush holder 70 are connected in the gear case 31 when a rear wiper motor is assembled. This enables the brush holder 70 to be high-accurately positioned in the gear case 31, thereby inhibiting characteristic variation of the rear wiper motor caused by reduction of positioning accuracy to improve yield. |
