  • Patent number: 7224136
    Abstract: A control apparatus for a closure device includes pinch detector for detecting a foreign body being pinched by an opening/closing member when the variation degree of a movement of the opening/closing member reaches a predetermined threshold value. When this control apparatus for a closure device determines that a vehicle is running, the threshold value is set at a second threshold value, which is reduced in a detection sensitivity of pinch as compared with a first threshold value set when the vehicle is stationary. When the apparatus detects that a load not smaller than a predetermined value is applied by disturbance to the opening/closing member in a closing direction, the threshold value is set at a third threshold value, which is reduced in the detection sensitivity of pinch as compared with the second threshold value.

  • Patent number: 6727613
    Abstract: A driving-side rotator of a clutch has a connecting hole, within which a connecting portion of a rotatable shaft is loosely fitted while providing a space between the connecting hole and the connection portion. The connecting hole of the driving-side rotator is engageable with the connecting portion of the rotatable shaft in a rotational direction to integrally rotate with connecting portion of the rotatable shaft. Two positioning holes are provided in a brush holder, and two positioning projections are provided in a gear housing to allow direct positioning of the brush holder and the gear housing relative to each other.

  • Patent number: 6700245
    Abstract: A rotatable shaft of a motor main body and a worm shaft of a speed reducing unit are drivingly coupled to each other by a clutch. Surrounding walls, which are arranged radially outward of the clutch to substantially entirely surround the clutch in an imaginary plane that extends substantially perpendicular to the axis of the worm shaft, are formed integrally with a gear housing. Thus, the surrounding walls restrain outward movement of grease, which is applied to predetermined portions of the clutch, so that effluence of the grease from the clutch is restrained.

  • Patent number: 6320335
    Abstract: In a reciprocating drive device, for example, in a power window device for a vehicle, a drive member is reciprocated by transmitting a rotating force from a motor to a regulator. A driven gear of the regulator is engaged with a drive gear fixed outside a synthetic resin housing of the motor to an output shaft of the motor. In the reciprocating drive device, a relative movement between the housing of the motor and a support base to which the housing is attached with screws is surely prevented by a relative-movement preventing unit having an engagement structure between the support base and the housing.
