A power supplying system for supplying power to a self-driving closure device in which a driving source for driving the closure device for opening and closing an opening moves together with the closure device includes a lead wire having one end connected to a power source and the other end connected to the driving source. The side of the lead wire connected to the power source is supported at a midpoint between the positions of the upper and lower limits of movement of the driving source, while the side of the lead wire connected to the driving source is supported in such a manner as to move together with the driving source. The lead wire is thus made to swing in conjunction with the movement of the driving source so as to supply power to the moving driving source. A guide shaft is provided along the direction of movement of the driving source, and a helical portion formed in the lead wire is extended or shrunk along the guide shaft so as to supply power to the moving driving source.

A self-driving closure device for moving a closure member such as a window glass of a vehicle between an open position and a close position. The device has a motor movable together with the closure member. The motor has a pinion that meshes with a rack secured to the vehicle door or a rotary drum on which an intermediate portion of a wire secured to the door is wound, so that a thrusting force for driving the window glass between the open and close positions is generated as a reactional force as the pinion or the drum is rotated. A mechanism is provided between the motor and the window glass so as to absorb any offset between the direction of movement of the glass and the direction of movement of the motor, so as to ensure smooth movement of the window glass.

A closure device for opening and closing an opening by moving a closure member substantially vertically has a motor for driving the closure member. The motor is secured to a lower portion of the closure member and within substantially the same plane as the plane of movement of the closure member. Accordingly, it is possible to prevent an eccentric load from being applied to the closure member.

A yoke housing that receives an armature has a plurality of permanent magnets (primary magnetic poles) secured to an inner peripheral surface of the yoke housing. Furthermore, the yoke housing includes a plurality of groove-like reduced thickness portions for increasing a magnetic resistance. Each reduced thickness portion extends along a center line of a corresponding one of the permanent magnets.

There is provided a mobile member position detection apparatus in which not only high-accuracy detection of a position of a window glass or the like of a power window apparatus but also setting of an initial position being free from cumbersome adjustment can be realized with a simple structure at low cost. In this position detection apparatus, a transmission plate and a cam plate are rotated together with the rotating shaft of a window regulator, and a limit switch is rendered conductive to detect a predetermined rotational position. Thereafter, when the rotating shaft is rotated, the intermeshing state between a tooth portion and a tooth portion obtained by a wave washer is released, and rotation of the rotating shaft is not transmitted to the cam plate. Therefore, when the rotating shaft (drive motor) is sufficiently rotated during an incorporating operation, an initial state wherein a projecting portion is brought into contact with a stopper to render the limit switch conductive is automatically set.

In a motor device for vehicles, a brush holder is interposed between a motor yoke housing and a reduction gear unit housing has a holder body and a connector unit integrally formed with each other. The connector unit holds therein connector terminals having base ends connected to brushes. A sealing cover is molded integrally on the holder body and the base ends of the connector terminals. The sealing cover seals insides of the yoke housing and the gear housing water-tightly from the outside. The sealing cover is preferably made of rubber, elastomer or adhesive resin, and formed with the brush holder by two-color molding. The sealing cover has a cylindrical cover part extending from the connector unit, and the motor device is mounted in a vehicle door with the cylindrical cover part being attached to the vehicle door for electrical connection with an external power source.

A clutch includes a stopper secured to a gear housing of a motor. Once the stopper is secured to the gear housing, the stopper restrains axial movement of rolling elements by restraining axial movement of a support member, which rotatably supports the rolling elements, to retain the rolling elements within a collar. A driven-side rotator of the clutch includes reinforcing ribs for reinforcing engaging projections of the driven-side rotator.

There is provided a mobile member position detection apparatus in which not only high-accuracy detection of a window glass or the like of a power window apparatus but also setting of an initial position being free from cumbersome adjustment can be realized with a simple structure at low cost. In a position detection apparatus, a ring gear is rotated together with a motor output shaft, and a predetermined rotational position is detected by a mobile contact and a fixed contact. In this case, since a projecting portion of a gear base is brought into contact with a contact surface of a base plate to hold the gear base, a difference between loss torque of the gear base and loss torque of the ring gear increases, and a planetary gear is not unnecessarily revolved. Thereafter, when the output shaft is rotated, holding of the carrier by a wave washer is released, and rotation of the output shaft is not transmitted to the ring gear. Therefore, when the output shaft is sufficiently rotated in an incorporating operation, an initial state can be automatically set.

In a position detector, a ring gear rotates with a motor output shaft and a specified rotation position is detected by a move contact and fixed contacts. When the output shaft rotates thereafter, holding a carrier by a wave washer is released and the transmission of rotation of the output shaft to the ring gear is dropped. Therefore, by rotating the output shaft sufficiently at the time of assembling, an initial state, in which a protrusion section abuts a protrusion and the move contact contacts the fixed contact, is set automatically.

A device for detecting a position of a moving body is provided in which a position of a moving body such as a window glass of a power window device can be detected with high accuracy, initial positions can be set without complicated adjustment, such can be realized with a simple structure and at a low cost, and assemblability can be greatly improved. In the device for detecting a position of a moving body, fixed contacts press-contact a flange portion of a ring gear from a side opposite a side at which a cover plate is disposed. Accordingly, the fixed contacts can be installed after the ring gear. In a state in which the ring gear is provisionally installed, press-contact force of the fixed contacts is not applied to the ring gear. As a result, the ring gear does not rise and positional deviation does not occur, and therefore, the assemblability can be greatly improved.
