VEHICLE DOOR DEVICE

A vehicle door device includes: a braking control unit applying a braking force to a swing door of a vehicle by controlling an operation of a braking device; an action position detection unit detecting an action position of the swing door; and a vertical displacement detection unit detecting a vertical displacement of the swing door. The braking control unit does not execute braking control in a case where the action position of the swing door changes with the vertical displacement exceeding a predetermined gripping operation determination value, even in a case where an execution condition of braking control for applying the braking force is satisfied.
