A door opening and closing apparatus for a vehicle includes a transmission gear configured to be driven to rotate by a motor, a pulley arranged coaxially with the transmission gear and configured to open and close a vehicle door by moving a rope member with a rotation of the pulley, an output member arranged coaxially with the transmission gear and configured to bring a door lock to a holding state with a rotation of the output member, a first clutch housed in the pulley in a state being coaxial with the transmission gear, the first clutch selectively permitting and prohibiting a rotation transmission between the transmission gear and the pulley, and a second clutch housed in the transmission gear in a state being coaxial with the transmission gear, the second clutch selectively permitting and prohibiting a rotation transmission between the transmission gear and the output member.

Provided is a device for opening and closing a sliding door, of which collinearly placed doors slide respectively to overlap each other such that the sliding door is opened or closed. The device includes a sliding portion formed on a surface on which doors come into contact with each other in order to prevent the doors from interfering with each other when the doors are opened; a pair of rail frames formed on a top surface of the furniture and provided with a rail protruding upwardly such that each door is slid forward and backward on the rail, the rail having both sides in which bending portions are formed; and rotational members, each of which is installed to one side of a connection bracket to be rotatable in a curved section of the bending portion while being lifted and slid on the rail.

A pre-assembled fitting group for a window or door has a drive rod portion, which is movable in the rebate circumferential direction, a first control element, and a second control element which is arranged on a cross slide. The first and the second control elements cooperate and are coordinated with one another in such a way that a displacement of the first control element by the drive rod portion causes a displacement of the cross slide. A guide part that can be fixedly mounted on the sash, wherein the cross slide is at least partially movable relative to the guide part.

A vehicle door system includes, among other things, a vehicle body and a slidable door that is slidable back and forth relative to the vehicle body between an open position and a closed position. The system further includes an alignment bracket assembly having a door-mounted portion and a body-mounted portion. The door-mounted portion and the body-mounted portion are wedged against one another when the slidable door is in the closed position to restrict movement of the slidable door relative to the vehicle body when the slidable door is in the closed position.

A vehicle includes a sidewall, a first door moveable between an opened position and a closed position, a second door moveable between an opened position and a closed position, a first track secured to the sidewall and a second track secured to the sidewall. A first roller is connected to the first door and is moveable along the first track as the first door moves between the opened position and the closed position. A second roller is connected to the second door and is movable along the second track to the first track and along the first track to the second track as the second door is moved between the opened position and the closed position.

A second roller is connected to the second door and is movable along the second track to the first track and along the first track to the second track as the second door is moved between the opened position and the closed position.

An entrance handrail includes: a base portion provided proximal to an entrance opening of a vehicle so as to be turnable; a handrail body that extends from the base portion; and a rail portion that extends from the base portion and that holds a second end portion of a link arm such that the second end portion is slidable. A first end portion of the link arm is turnably attached to a slide door that is movable along an outer wall surface of the vehicle to open and close the entrance opening. The handrail body and the rail portion project outward of the vehicle when the slide door opens the entrance opening. The handrail body and the rail portion are disposed to extend along the slide door when the slide door closes the entrance opening.

A slide door harness includes a wiring material, a vehicle body-side fixing portion provided in a vehicle body to rotatably hold an end of the wiring material below a lower end of an inner surface member of a slide door, and a door-side fixing portion provided on the slide door to rotatably hold another end of the wiring material, and the door-side fixing portion includes a holding portion configured to hold the another end of the wiring material toward the lower end side of the inner surface member, a first rotating shaft configured to allow the holding portion to rotate around a first rotation axis, and a second rotating shaft configured to allow the holding portion and the first rotating shaft to integrally rotate around a second rotation axis intersecting the first rotation axis.

An apparatus for window is used for moving a movable window plate among an insertion position for being inserted into an aperture portion of a fixed window plate, an extraction position for being extracted from the aperture portion toward an indoor side, and an opening position for being moved from the extraction position in a sliding direction that is different from an inserting and extracting direction to open the aperture portion. The apparatus includes a rotating shaft rotatably supported at a predetermined position for the movable window plate; a movement conversion mechanism configured to convert a rotation of the rotating shaft into a translation of the movable window plate between the insertion position and the extraction position; and a drive shaft, fixed to the rotating shaft, configured to rotate the rotating shaft around a central axis of the rotating shaft by revolving around the central axis of the rotating shaft.
