<P>PROBLEM TO BE SOLVED: To provide an electric motor device and an electric motor device for driving a wiper which improve the transportation efficiency and thereby reducing logistic costs. <P>SOLUTION: An electric motor device 1 includes: a transmission mechanism 20 transmitting torque of an electric motor part 10 to an output shaft 45; and a gear case 21 (case) having an opening 21b. The transmission mechanism 20 is housed in the gear case 21 and the electric motor part 10 is attached to the gear case 21. The electric motor device 1 has a bracket closing the opening 21b and used for fixing the gear case 21 to a vehicle (attached body); and a tentative cover 90 which has an outer shape smaller than the bracket and may close the opening 21b. In the gear case 21, a screw fastening hole 22b (engagement part), which may engage with the bracket, and a claw part 31 (tentative engagement part), which may engage with the tentative cover 90, are formed at a periphery of the opening 21b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
