Title:
WIPER MOTOR
Document Type and Number:
Japanese Patent JP2018183039
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a wiper motor which can effectively block a noise component caused by the rotation of the wiper motor and can easily implement a configuration that blocks the noise component.SOLUTION: A circuit includes a low voltage line 58 that connects a Low terminal 36L of a connector 36 and a positive electrode terminal 40L of a brush 40 via a choke coil 38L, a negative electrode terminal 40N of the brush 40 connected to a conductive partition wall 50 of a housing in which one end covers an opening of a yoke, a ground line 54 that connects an end portion 54A connected to the partition wall 50 and a ground terminal 36N of the connector 36, and a capacitor 48 in which one end is connected between the choke coil 38L of the low voltage line 58 and the Low terminal 36L of the connector 36 and the other end is connected between the first connection terminal 50 of the ground line 54 and the ground terminal 36N of the connector 36.SELECTED DRAWING: Figure 1
