Abstract: A vehicular door device causes a door to perform an opening-closing operation, based on an operation of a link mechanism formed of first and second link arms. Further, the first link arm is provided with a hand placement portion that rotates integrally with the first link arm. Then, the vehicular door device is configured in such a way that the first link arm supports a load applied to the hand placement portion.

Abstract: A wiring harness routing structure includes at least a sub-link arm and a routed line. The sub-link arm includes one end that is rotatably coupled to a vehicle body by using a first coupler, and another end that is rotatably coupled to a door body by using a second coupler, and slidably supports the door body relative to the vehicle body, while rotationally moving relative to each of the vehicle body and the door body. A routed line is routed and provided along the sub-link arm, and connects a vehicle-body-side connector and a door-side connector. In addition, the routed line is routed through a lower side in a height direction of the first coupler that is coupled to the sub-link arm, in a state where the door body has slid to be fully opened.

Abstract: There is provided a door support device that can restrict a door from being overhanging greatly from a vehicle body when the door opens or closes a door opening. The door support device includes: a main link with a proximal portion rotatably connected to the vehicle body and a distal portion rotatably connected to the door; a sub-link with a proximal portion rotatably connected to the vehicle body and a distal portion rotatably connected to the door, each of the portions being connected at a position different from a position for the main link; and a door drive unit that drives the door. The main link and the sub-link constitute a four-bar link mechanism together with the vehicle body and the door. The main link includes an adjusting mechanism for adjusting a distance between a connecting portion connected to the vehicle body and a connecting portion connected to the door.

Abstract: In a wiring harness routing structure, a main link arm slidably supports a door body relative to a vehicle body, while rotationally moving relative to each of the vehicle body and the door body. A sub-link arm is provided on a lower side in a height direction of the main link arm, and slidably supports the door body relative to the vehicle body, together with the main link arm, while rotationally moving relative to each of the vehicle body and the door body. A routed line is routed and provided along the sub-link arm, and connects a vehicle-body-side connector and a door-side connector. In addition, the routed line is routed through a side closer to the main link arm of a first coupler that is provided in a sub-link mechanism.

Abstract: A vehicle door apparatus includes first and second link arms each having a first pivot coupling point with respect to a vehicle body and a second pivot coupling point with respect to a door of a vehicle. The vehicle door apparatus includes a coupling length variable mechanism provided on at least one of the first and second link arms and configured such that a coupling length serving as a distance between the first and second pivot coupling points is variable. The coupling length variable mechanism is configured to change an opening and closing motion track of the door.

Abstract: A harness body (10) is guided to a fixed portion (522) on a side of a slide door (520) by a harness guide tool (40) at an other end portion (612) of a first arm member (610) on a side of a vehicle body (510) and includes a third routing portion (13) having a fixing portion (13a) fixed to the fixed portion, a link mechanism (600) includes a second arm member (620) on the side of the slide door coupled to the other end portion of the first arm member via a second rotation shaft (641), and the third routing portion is twisted and deformed about its own axis between the harness guide tool and the fixing portion when the first arm member and the second arm member are relatively rotated with respect to each other.

Abstract: A vehicular door device includes a door-side engagement portion including a guide groove that includes a pair of side wall portions facing each other in a vehicle width direction and extends in an opening-closing operation direction of the door, a vehicle body-side engagement portion including a shaft-shaped engagement portion extending in an up-down direction of a vehicle, and an expansion mechanism provided in a second link arm. In an opening-closing operation position near a full closed position of the door where the door-side engagement portion and the vehicle body-side engagement portion engage with each other, the shaft-shaped engagement portion is disposed in the guide groove. The shaft-shaped engagement portion is relatively displaced along an extending direction of the guide groove while a change in length of the second link arm, based on an operation of the expansion mechanism, is accompanied, and thus the door can perform an opening-closing operation.
