An electric actuator, which includes an exposed actuator terminal, for eliminating the need for insert molding and facilitating the manufacturing of a housing while preventing liquid from entering the housing. The actuator includes a motor. The housing is attached to the motor and includes an opening. A control circuit board accommodated in the housing controls the motor. An actuator terminal is arranged on the control circuit board and connected to an external terminal of an external connector through the opening. A terminal support arranged on the control circuit board supports the actuator terminal. A hollow fitting is attached to the terminal support and fitted into the opening so as to extend into the housing. A seal, arranged between the terminal support and the fitting, seals the housing.

A door opening and closing apparatus for a vehicle includes a first hinge base adapted to be mounted to a vehicle body, a second hinge base adapted to be mounted to a vehicle door, a four-link hinge including a first hinge arm and a second hinge arm for connecting the first hinge base with the second hinge base, the four-link hinge supporting the vehicle door between a fully open position and a fully closed position, a fully open position locking mechanism adapted to be mounted on the vehicle door for locking the vehicle door relative to the vehicle body at the fully open position, and an unlocking mechanism adapted to be mounted on the fully open position locking mechanism for releasing a locked condition of the vehicle door.

Door opening and closing apparatus for vehicle

A power window device for use in a vehicle for raising and lowering each window glass. The power window device includes a drive unit for each door operable for raising and lowering the associated window glass. Each drive unit includes an EEPROM for retaining mounting position information of the position in the vehicle at which the window glass driven by the associated drive unit is located. A processor in each drive unit retrieves steering wheel position information of whether the steering wheel is located in the right or left side of the vehicle. The processor recognizes the position in the vehicle at which the associated drive unit is installed based on the mounting position information and the steering wheel information. This enables the drive unit to be used for both right hand and left hand drive vehicles.

Power window device

A power window device for lowering and raising window glasses. A window switch is operated to move a corresponding window glass. A motor drives the window glass when the window switch is operated. An ECU is provided for each window glass to control the motor in accordance with the operation of the window switch. An engine switch shifts positions to drive an engine. A control signal generator generates a signal to validate or invalidate control of the ECU over the motor. A control circuit determines that a signal wire connecting the ECUs to the control signal generator is in an unexpected condition when a signal cannot be received. The control circuit overrides the signals generated by the control signal generator when the signal wire is in an unexpected condition.

A device for opening and closing a vehicle slide door window includes a window regulator mechanism having a lift arm supporting a pane and a driving mechanism for moving the pane in downward and upward directions when the driving mechanism rotates the lift arm in opposite directions to effect opening and closing of a window portion. A cam plate is arranged on the rotational axis of the lift arm and is operatively associated with the lift arm for rotating together with the lift arm and a detection lever is positioned adjacent to the cam plate and brought into contact with the cam plate at an end of the detection lever.

According to the present invention, on the through opening edge portion, the flange portion is formed, and by arranging the outer surface of the axle portion to slide and rotate on the inner face of the flange portion, the first and second equalizer arms are pivotally supported by the lift arm. The circular projected portion formed around the axle portion contacts on the lift arm face to provide the predetermined clearance between the top portion of the flange portion and the lift arm face, and undesirable friction increase or stick slip there between is avoided. The lift arm and the first and second equalizer arms can be made of thinner steel plate material, and weight and cost reduction is obtained. The flange portion and the through opening are formed by burring on the lift arm, and also the axle portion and the circular projected portions are formed by stamping directly on the first equalizer, and also the weight and cost reduction of the window regulator is realized.

A strong metal plate having flexibility includes a flat portion, a plurality of first protuberances projecting from the flat portion in one direction of the thickness direction of the flat portion and a plurality of second protuberances projecting from the flat portion in the other direction of the thickness.

Metal plate of high strength and flexibility

A window regulator apparatus for moving a window glass in the vertical direction of a vehicle door incorporates a plurality of pulleys rotatably supported on the vehicle door, a drum rotatably supported to the vehicle door, and a cable jointed to the window glass, guided to the pulleys and looped around the drum. The drum includes a first spiral groove which supports one end of the cable and a second spiral groove which supports the other end of the cable. The second spiral groove is formed to spiral in a direction opposite the first spiral groove. The extending points of the cable relative to the first spiral groove and the second spiral groove are defined to gradually change where the cable releases from the drum in the radial direction of the drum by the rotation of the drum.

Window regulator apparatus

A window regulator for a vehicle has a lift arm pivotally mounted on a door panel of a vehicle. A gear plate including teeth on the periphery thereof is connected to one end of the lift arm. A driving device engages with the teeth and moves the gear plate. A movable rail is connected to a window glass, the movable rail engaging with the other end of the lift arm. Holes are disposed in one end of the lift arm and convex portions are disposed in said gear plate, the convex portions being inserted into said holes and pressed into a flat shape.
