Problems solved by technology

Therefore, when the axial dimension of the sealing portion is equal, there is a problem that the gap between the brush holder and the yoke and between the yoke and the bracket cannot be sufficiently sealed, and the waterproof performance of the electric motor is reduced.
In this way, there is a problem that the shape of the seal portion is not constant and its axial dimension is complicated, which increases the time and cost of manufacturing the seal portion.

Embodiment Construction

[0017] Hereinafter, a motor according to an exemplary embodiment of the present application will be described with reference to the drawings. In addition, the scope of the present invention is not limited to the following embodiments, and can be changed arbitrarily within the scope of the technical idea of ​​the present invention. In addition, in order to facilitate understanding of each structure, in the following drawings, the scale, number, etc. in each structure may be different from the scale, number, etc. in the actual structure.

[0018] In addition, in the drawings, an XYZ coordinate system is shown as a three-dimensional orthogonal coordinate system for convenience. In the XYZ coordinate system, the direction of the Z axis is the same as figure 1 The axial parallel direction of the central axis J is shown. The X-axis direction is a direction perpendicular to the Z-axis direction, and is a direction in which the connector portion 53 protrudes. The Y-axis direction i...

Abstract

The invention provides a motor. The motor may include a sealing part manufactured by an elastomer. A brush disk assembly comprises a cylindrical brush disk cylinder part surrounding the shaft in the circumferential direction; and a brush disk flange part radially extending from the cylindrical brush disk cylinder part to the outer side. The sealing part comprises a first sealing part which is axially clamped while contacting the upper surface of the brush disk flange part and the housing or the lower surface of the brush disk flange part and the bracket. At least one of the radial inner surface of the housing and the radial inner surface of the bracket has an inclination surface toward a connection surface between the housing and the bracket and far away from a central axis. The first sealing part is clamped between the housing and the bracket through the inclined surface while contacting the housing and the bracket.

Description

technical field [0001] The invention relates to a motor. Background technique [0002] Conventionally, among electric motors, there is a motor that includes a sealing portion that seals a gap between members constituting an outer frame of the motor. For example, Japanese Patent Application Laid-Open No. 2014-110697 describes an electric motor including a brush holder provided with a sealing portion made of rubber. The brush holder is held by the yoke and the bracket by means of the seal. Such an electric motor can be used outdoors such as a vehicle, and water can be prevented from entering the inside of the motor by the sealing portion. [0003] In the electric motor as described above, the seal portion is sandwiched between the brush holder (brush plate) and the yoke (casing) and also between the yoke and the bracket. Here, the axial dimension between the brush holder and the yoke and the axial dimension between the yoke and the bracket tend to vary depending on parts or...
