Embodiment Construction

[0013] One embodiment of the motor will be described below.

[0014] Such as figure 1 As shown, the motor 10 of this embodiment is used as a drive source for a automatic window device of a vehicle, and includes a motor body 11 and a deceleration unit 12 that decelerates the rotational speed of the motor body 11 .

[0015] The yoke housing 13 of the motor main body 11 includes a cylindrical body portion, a bottom, an open end, and a flange portion 14 . The flange portion 14 extends radially outward from the open end. The flange portion 14 has a flat plate shape perpendicular to the axial direction. A field magnet 15 is fixed to an inner peripheral surface of the yoke case 13 , and a rotor 16 is disposed inside the field magnet 15 .

[0016] A rotor core 18 and a commutator 19 are integrally fixed to a rotating shaft 17 of the rotor 16 . A winding 18 a is wound around the rotor core 18 . To the commutator 19, the end of the winding 18a is connected. The rotor core 18 is ra...

Abstract

A motor and a method for manufacturing the motor are provided. The motor comprises a motor main body having a magnetic yoke housing with a flange part provided with a screw fixing part, a deceleration part having a gear box provided with a screw fixing part, and a resin brush rack fixed via a screw when clamped by the flange part of the magnetic yoke part and the gear box of the deceleration part. A link of the brush holder is located between a screw fastening portion of the flange and a screw fastening portion of the gear housing. A connector is linked to a holder main body by the link. The link includes a screw insertion hole and first and second bridges. A metal terminal, which electrically connects the holder main body and the connector, is embedded in each of the first and second bridges.

Description

technical field [0001] The present invention relates to a motor with a reduction mechanism provided with a brush holder and a method of manufacturing the motor. Background technique [0002] Conventionally, for example, a motor with a speed reduction mechanism disclosed in Japanese Patent Application Laid-Open No. 2012-244851 includes a motor main body including a yoke housing and a speed reduction unit including a gear box. In a state where the resin brush holder is sandwiched between the flange portion of the yoke case and the gear case, the screw fixing portion of the flange portion and the fixing portion of the gear case are fastened with screws. The brush holder includes: a holder main body holding a brush for power supply; a connector part for connecting to the outside; and a connection part connecting the holder main body and the connector part. [0003] However, in the motor as described above, from the requirement of flattening in the direction perpendicular to the...
