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.

A vehicle door device comprising:
- 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,
- wherein the biasing force applying device applies the biasing force based on an elastic force of an elastic member attached to one of the door and the first link arm that is elastically deformed by the operation of the link mechanism when the elastic member contacts the other of the door and the first link arm.
