In a geared motor, a worm wheel, an O-ring, a transmission plate and an output gear are installed to a support shaft. The O-ring is placed in an inner space of a receiving through hole of the transmission plate, through which the support shaft is received. Grease is applied to an outer peripheral surface of the support shaft. A grease relief passage, which relieves the grease, extends between the output gear and the transmission plate.

A pinched object detection apparatus includes a couple of pressure sensors arranged at lateral end portions of a backdoor of a vehicle and another couple of pressure sensors arranged at lateral end portions of a rear opening of the vehicle. An object pinched between the lateral end portions of the rear gate and the backdoor can be detected with the corresponding pressure sensor arranged at the backdoor or pressure sensor arranged at the rear opening. Furthermore, an object pinched between the lateral end of the rear opening and an opposing gas damper can be detected with the corresponding pressure sensor arranged at the rear opening.

In a foreign material detector for a sliding door, a pressure sensor is disposed being offset toward a vehicle interior side and a substantial vehicle front side of a hem and being offset toward a substantial vehicle exterior side with respect to a position supported by a bracket as well, in order for the foreign material to be detected, even though a direction of a reaction force effected from a foreign material is tilted and intersected with respect to a moving direction of the sliding door.

According to a pressure sensitive sensor and a method of treating a terminal of a pressure sensitive sensor of the invention, a covering portion is formed by a thermoplastic resin material for hot melt molding or a photo-curing resin material cured by absorbing light energy. That is, molding pressure in molding is lower than molding pressure in molding by a general injection molding method. Therefore, a possibility of effecting adverse influence on respective connecting portions of an electrode line, a resistor, a conductive piece and a lead wire by the molding pressure is extremely low and disconnection caused by operating the molding pressure on the connecting portions can reliably be prevented.

In a drive apparatus for a pivotable window pane held pivotally at one end thereof by a window frame through hinges, an output shaft driven by an electric motor through a reduction mechanism is coupled to a first link which in turn is coupled to the other end of the window pane through a second link and a hinge. The first link and the second link are so arranged that the joint therebetween moves along an arcuate path. The output shaft is positioned at a side closer to the hinge than the center of the arcuate path is. Further, the joint moves within the outer confine of the motor and the reduction mechanism.

In an electric motor having a rotation detection sensor, a pair of engagement recesses are provided on an axial end surface of a resin cylindrical body of a commutator. A permanent magnet is held around a rotary shaft of the motor with its one axial end surface being in abutment with the axial end surface of the cylindrical body. A pair of engagement recesses is provided on the other axial end surface of the magnet. A resin busing having a cylindrical part and a disk part is fitted on the rotary shaft at the side of the other axial end surface of the magnet. A pair of engagement protrusions is formed on the cylindrical part to be engaged with the engagement recesses of the cylindrical body, thereby restricting a relative movement between the bushing and the cylindrical body. Further, a pair of engagement protrusions is formed on the disk part to be engaged with the engagement recesses of the magnet, thereby restricting a relative movement between the bushing and the magnet. Thus, the magnet of the rotation sensor is fixedly mounted around the rotary shaft without using an adhesive bond.

A power window actuator including an electric motor, a reduction gear train for reducing rotational speed of the motor and a linkage mechanism connected to the gear train opens and closes a pivotable quarter window or a rear side vent. The rotation of the motor is mechanically stopped by structural members totally enclosed in a housing containing the motor and the gear train when the pivotable window comes to a fully opened or a fully closed position. An electric current supply to the motor is automatically discontinued by operation of a controller. An output shaft connected to a final stage gear of the speed reduction mechanism is extended outwardly from both sides of the housing. The linkage mechanism is composed of a pair of first links connected to the extended output shaft and a second link pivotably connected to the first links, so that the first links do not drop off from the output shaft without being fastened by a fastening member. Thus, the assembling process of the linkage mechanism is simplified.

Actuator for pivotable quarter window

A power window actuator including an electric motor, a reduction gear train for reducing rotational speed of the motor and a linkage mechanism connected to the gear train opens and closes a pivotable quarter window or a rear side vent. The rotation of the motor is mechanically stopped by structural members totally enclosed in a housing containing the motor and the gear train when the pivotable window comes to a fully opened or a fully closed position. An electric current supply to the motor is automatically discontinued by operation of a controller. To enclose the structural members for stopping the motor in the housing, a first projection is formed on a final stage gear of the gear train and a second projection on an inside surface of the housing. Both projections abut against each other to stop the motor when the pivotable window is driven to predetermined positions. Thus, the actuator is made small in size and at a low cost.

A resistor formed by a laminated structure having a resistance body interposed between two conductive plates, electrical connection members being connected to the conductive plates, and a method for manufacturing the resistor. The resistor includes a first connection portion formed on a first conductive plate by partially cutting off a laminate part of a second conductive plate and the resistance body, and a second connection portion formed on the second conductive plate by partially cutting off a laminate part of the first conductive plate and the resistance body. The method for manufacturing the resistor includes the steps of applying solder to one of the two conductive plates and the resistance body, thereafter passing the component through a high temperature oven and thereby melting the solder, and fixing the resistance body and the two conductive plates together in an electrically conductive state with the resistance body interposed between the two conductive plates, by solidifying the solder.

Resistor and resistor manufacturing method

An automatic controller for use with a motor. A switch interconnects the motor and a power source for selectively establing an electrical connection therebetween. A relay coil is connected to the motor. When the motor is connected to the power source via the switch, the relay coil latches the switch in a steady connecting state. When increased current overdraw of the motor is sensed, a current-limiting thermistor limits or interrupts the current flow across the relay coil, to set the switch to a disconnect state and to cause the motor to stop.
