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 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.
