Abstract: A vehicle door device includes first and second link arms each including a first pivotal connection point to a vehicle body and a second pivotal connection point to a door of a vehicle, and a drive unit that opens and closes the door based on an operation of a link mechanism formed by the first and second link arms by using at least one of the first and second link arms as a drive link and pivoting the drive link. The drive unit includes an actuator that outputs drive torque, and a transmission mechanism that transmits the drive torque to the drive link disposed at a position separated from the actuator. The transmission mechanism includes a torque input portion that inputs the drive torque to the drive link, and a power transmission member that forms a transmission path for the drive torque in a state of extending between the actuator and the torque input portion and has flexibility to enable transmission of the drive torque in a bent state.

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.
