WIPER MOTOR

Document Type and Number:

WIPO Patent Application WO/2012/029608

Kind Code:

A1

Abstract:

A wiper motor is provided with: a reduction mechanism (26) for reducing the speed of rotation of the motor shaft (17) and transmitting the rotation having the reduced speed to a worm wheel (35); and a motion conversion mechanism (29) for converting the rotational motion of the worm wheel (35) into a rocking motion and outputting the rocking motion to an output shaft (28). The reduction mechanism (26) is contained within the reduction mechanism containing chamber (27) of a gear frame (21), and the motion conversion mechanism (29) is contained within the motion conversion mechanism containing chamber (30) of the gear frame (21). A support surface (37) is formed on the inner surface of the bottom wall (30a) of the motion conversion mechanism containing chamber (30). The support surface (37) is flush with the other end surface (35b) of the worm wheel (35) in the axial direction, the worm wheel (35) being rotatably contained within the reduction mechanism containing chamber (27). The support surface (37) is formed on the bottom wall (30a) of the motion conversion mechanism containing chamber (30) so as to expand over the entire area of the bottom wall (30a), the area facing a pinion gear (40) and the motion conversion member (41).
