Abstract: A power window apparatus for opening and closing a window glass actuates a window regulator based on power transmitted from the output gear of a motor to the sector gear of a window regulator. A range in which the output gear and the sector gear mesh with each other includes a normal operation range and a low speed operation range. In the normal operation range, the window glass is moved at a normal speed. In the low speed operation range, the window glass is moved at a speed lower than the normal speed from a near-fully closed position to a fully closed position of the window glass.

Abstract: A brush holder includes a base member and a retaining member mounted on the base member. The retaining member includes a first brush retaining portion and a first coil retaining portion. A first choke coil is electrically connected to a first brush. The first choke coil includes a first coil terminal extending to the outside of the first coil retaining portion. The base member includes a connector portion, a first conductive member, and a first coil terminal support portion. The first conductive member extends from the connector portion and is electrically connected to the first coil terminal at a first connecting portion. The first coil terminal support portion supports the first coil terminal between the first connecting portion and the first coil retaining portion.

Abstract: Each of a plurality of brushes is tilted relative to an imaginary plane that is perpendicular to a rotational axis of an armature and is placed on one axial side of a brush holder, at which an interior of a yoke housing is located. A radial inner end part of each brush has a slide contact surface, which is generally parallel to the rotational axis of the armature and slidably contacts an outer peripheral surface of a commutator. At least a portion of the slide contact surface of each brush is axially disposed outside of an opening of the yoke housing.

Abstract: A gear housing accommodates a worm shaft. A brush holder includes a base member and a retaining member loosely fitted to the base member. The base member is located between the gear housing and the retaining member. The retaining member retains a first brush and a second brush. The retaining member has a pair of positioning poles, and the gear housing has a pair of positioning projections. The positioning poles and the positioning projections are engaged with each other so as to prevent the retaining member from being moved in a direction perpendicular to the axial direction of the rotary shaft.

Abstract: A control circuit member provided in a motor is disclosed. The motor includes a motor main body having a rotary shaft and a gear housing integrated with the motor main body. The control circuit member includes a circuit substrate on which a rotation detecting element is mounted and a substrate support member. The circuit substrate is accommodated in a circuit accommodating portion in the gear housing. The substrate support member supports the circuit substrate inside the circuit accommodating portion. The control circuit member is configured to be insertable into the circuit accommodating portion along the axial direction of the rotary shaft. The circuit substrate is configured to be arrangeable inside the circuit accommodating portion while being inclined with respect to the axial direction of the rotary shaft, so as to cause the rotation detecting element to approach the detector magnet.

Abstract: A motor includes: a motor element with a rotation shaft; a speed reduction element having a rotation speed reduction device for reducing a rotation speed and a gear housing for accommodating the reduction device; and a water proof sheet. The gear housing includes: an accommodation portion having a communication passage and an accommodation concavity; and a cover having a breathing hole. The breathing hole has a cover side opening, which connects to an accommodation side opening of the communication passage. An inside of the motor element is connected to an outside of the gear housing through the breathing hole and the communication passage. The cover seals an opening of the accommodation concavity. The water proof sheet having water proof property and gas permeability is disposed between the accommodation side opening and the cover side opening.

Abstract: A brush holder of a motor is provided with a holder body portion and a connector portion, which are integrally formed from a resin. The holder body portion is installed in a yoke housing of the motor to hold a brush to be in slide contact with a commutator. The connector portion is connected with an external connector to energize an armature. A grounding terminal is embedded in brush holder to extend from the holder body portion to the connector portion to be connected to a grounding line of the external connector. A capacitor is installed on the holder body portion to connect a point on a power supply terminal between the connector portion and the brush to the grounding terminal.

Abstract: A holder-side connecting portion 10c provided on a brush holder 10 and a connector-side connecting portion 16b provided on a connector portion 16 are electrically and mechanically connected with each other. The holder-side connecting portion 10c and the connector-side connecting portion 16b are clamped between a yoke housing 4 and a gear housing 21. For this reason, the connecting portions 10c and 16b for connecting the brush holder 10 and the connector portion 16 are prevented from being externally exposed. As a result, the insulation of the connecting portions 10c and 16b can be secured without complicating the construction of the connecting portions 10c and 16b by applying a special seal or the like to the connecting portions 10c and 16b.

Abstract: A motor includes an electrically conductive yoke housing and a noise limiter circuit. The yoke housing is configured in an oblate cylindrical cup form having a couple of opposed flat side walls and a couple of opposed arcuate side walls that join opposed lateral edges of the flat side walls together. The noise limiter circuit includes choke coils. Each choke coil is arranged adjacent to a corresponding corner of the yoke housing located between a corresponding one of the flat side walls and a corresponding one of the arcuate side walls in such a manner that each choke coil extends substantially parallel to a central axis of the yoke housing.

Abstract: A bonding structure of a valve seat has a port opening of a metallic head and an annular metallic valve seat insert. The valve seat insert includes an outer reduced diameter surface on its outer circumference. The material of the valve seat insert is harder than that of the head. The head plastically deforms upon pressing the valve seat insert toward the head. The deformed metal occupies any gap around the outer reduced diameter surface.
