A vehicle door glass elevating/lowering device performs elevating/lowering operation of window glass by a driving force of a drive source along a sash member along one of front and rear edges of the window glass in a door sash forming a window opening. The glass elevating/lowering device includes: a guide rail on the sash member; a slider having a glass support secured to the glass and a sliding part guided movably in the elevating/lowering directions with respect to the guide rail; and a transmission member that transmits the driving force of the drive source, in which a first sliding part regulated in position by the guide rail in at least one direction of the vehicle front-rear directions and a second sliding part regulated in position by the guide rail in at least the other direction of the vehicle front-rear directions are provided at mutually different positions in the elevating/lowering directions.

Vehicle door glass elevating/lowering device, door frame assembly, vehicle door opening/closing member driving device, and vehicle door opening/closing member driving device assembling method

A window regulator includes: a carrier piece attached to a window glass; a drive wire connected to the carrier piece to lift and lower the carrier piece; and a wire end connected to the drive wire. The carrier piece has a groove into which the drive wire is inserted, and a housing in which the wire end is housed. The housing has a bottom wall which the wire end engages, a first end wall communicating with the groove, a second end wall opposite the first end wall, an opening on a top side of the carrier piece into which the wire end is insertable, and a top wall. The walls restrict detachment of the wire end from the housing.

Window regulator

A window regulator includes: a carrier piece attached to a window glass; a drive wire connected to the carrier piece and configured to lift and lower the carrier piece; and a wire end connected to an end portion of the drive wire. The carrier piece has a wire end housing portion configured to house the wire end, a wire insertion groove communicating with the wire end housing portion, and a wire retaining portion extending at an upper end of the wire insertion groove. The drive wire is routed in the wire insertion groove. An upper side of the wire insertion groove includes an opening which opens in an upper direction crossing a routing direction of the drive wire. The wire retaining portion prevents the drive wire from coming out of the wire insertion groove by contacting the drive wire.

An assembling determination method and an assembling determination device for a vehicular opening-closing body driving device can determine a normal/abnormal winding of a drive wire around a spiral groove to ensure a quick and accurate action. The assembling determination method includes winding a drive wire around the spiral groove on the peripheral surface of a drive drum, wherein the drive wire drives a vehicular opening-closing body, arranging an inspection jig to face the drive drum surface via a clearance, determining that the drive wire is wound around the spiral groove in an abnormal manner when the inspection jig contacts the drive wire, and determining that the drive wire to be wound around the spiral groove in a normal manner when the inspection jig and the drive wire are contactless.

The method includes a step of fixing the other end of the drive wire to the drive drum; a step of temporarily placing one end of the drive wire in a temporary placement portion provided on the drum housing; and a step of applying tension to the drive wire by moving the one end of the drive wire to an engaging portion provided on the drive drum after canceling the placed state of the one end of the drive wire in the temporary placement portion by pulling a portion of the drive wire on the one end side thereof by winding a portion of the drive wire on the other end side thereof by the drive drum with the one end of the drive wire placed in the temporary placement portion.

Window regulator manufacturing method and tension applying method for drive wire

In a window regulator, and a method of producing the same, which moves a slider base along a guide rail via wires in accordance with rotation of a drum, includes a fitting portion having a first protrusion and a second protrusion provided on a drum housing which supports the drum, wherein the first protrusion protrudes from an abutting surface of the drum housing with which an end surface of the guide rail can come into contact and wherein the second protrusion protrudes from the abutting surface by a smaller amount of protrusion than that of the first protrusion, and the drum housing and the guide rail are joined by restricting movement of the guide rail in the thickness direction thereof by inserting the guide rail in between the first protrusion and the second protrusion. Workability during manufacturing of the window regulator is thereby improved.

Window regulator and method of producing window regulator

A window regulator and a jig to facilitate assembly. The window regulator includes a drum configured to be able to rotate in a normal direction/reverse direction, an annular wirepartly wound around a drum, guide membersandconfigured to guide the wirein such a manner that the wireis arranged along a direction of upward and downward movement of a window glass, slack preventing means configured to urge the wirein a stretching direction and eliminate the slack of the wire, and window glass mounting meansandconfigured to mount the window glassto a portion of the wireextending along the direction of upward and downward movement of the window glass, and a bracketbeing mounted rotatably on the inner panel and having the guide member, and being configured to guide the guide memberto a mounting position on the inner panel is provided.

Window regulator and jig

A window regulator includes a wire sag compensating mechanism. The wire sag compensating mechanism includes an outer tube arranged between the vicinity of a drum and at least one wire guide member allowing passage of a wire therethrough and fixed at an end on the side of the wire guide member to a member where the wire guide member may be provided. A tube holding portion may be provided on a member on which the drum is provided allowing movable engagement of the drum side of the outer tube and guiding the drum side of the outer tube in the axial direction of the outer tube. A spring may be provided for urging the drum side of the outer tube away from the drum. A disengagement restricting arrangement (e.g., projections and elongated holes) may be provided for restricting the outer tube from disengaging from the tube holding portion.

In a window regulator, when a pin boltprovisionally attached to a pulleyand a pulley supportis fastened to a door panelby a nut, the pulleyand the pulley supportare supported on the pin boltand attached to a predetermined position on the door panel. Here, in the above-described provisionally attached state, the pin boltis held in the pulleyby pin member holding clawsof the pulley, and the pulleyis held in the pulley supportby pulley holding clawsof the pulley support. Consequently, when the pin boltis to be fastened to a body panel, the pulley, the pulley support, and the pin boltcan be handled as a single part. Thus, the work of attaching a pulley and a pulley support to a body panel of a vehicle can be facilitated.

Wire type window regulator

A mounting device for mounting a cable-operated window regulator for a vehicle to an inner panel of the vehicle, the cable-operated window regulator includes a guide rail for guiding a window glass; a reversible winding unit for raising and lowering the window glass by winding and rewinding at least one cable which is wound on upper and lower guide members provided at upper and lower ends of the guide rail, respectively; upper and lower fixing member which are integrally formed with upper and lower ends of the guide rail, respectively; and a service hole formed on the inner panel. The lower fixing member is fixed to an outer surface of the inner panel near a lower edge of the service hole. The upper fixing member is fixed to an inner surface of the inner panel near an upper edge of the service hole.
