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 vehicle door device includes a first link arm and a second link arm 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, and a biasing force applying device configured to, during opening and closing operation of the door based on an operation of a link mechanism formed by the first link arm and the second link arm, apply, to the door, a biasing force in a direction in which a rotational moment around the second pivot coupling point generated based on inertia of the door generated in the door accompanied by the operation of the link mechanism is reduced.

Abstract: A vehicle door device includes first and second link arms having a first rotary coupling point with respect to a vehicle body and a second rotary coupling point with respect to a front door of a vehicle. The front door is opened toward a vehicle front side based on an operation of a link mechanism formed of the first and second link arms. The first link arm has the first rotary coupling point inside a dash panel provided at a front portion of a vehicle interior.

Abstract: A vehicle door device includes a first link mechanism formed of first and second link arms having a first rotary coupling point with respect to a vehicle body and a second rotary coupling point with respect to a door of a vehicle, and a second link mechanism formed of the first and second link arms provided independently of the first and second link arms forming the first link mechanism. First and second doors respectively supported by the first and second link mechanisms open and close independently in different directions based on operations of the first and second link mechanisms. At least one of the first and second link arms forming the first link mechanism and the first and second link arms forming the second link mechanism is provided with a coupling length variable mechanism that allows a coupling length between the first and second rotary coupling points to vary.
