Abstract:
To suppress shaking during opening and closing driving.SOLUTION: A vehicle door device 20 includes first and second link arms 11, 12 having a first rotational connection point X1 to a vehicle body 2 and a second rotational connection point X2 to a door 5 of a vehicle, respectively. Also, the vehicle door device 20 includes an actuator 25 that drives a link mechanism 15 formed by the first and second link arms 11, 12 to open and close the door 5. In addition, The vehicle door device 20 includes a connection length variable mechanism 35 provided on the second link arm 12 that enables a connection length between the first and second rotational connection points X1 and X2 to be changed. Furthermore, the vehicle door device 20 changes the opening/closing movement trajectory of the door 5 based on the operation of the connection length variable mechanism 35. The actuator 25 imparts driving force to the first link arm 11 on which the connection length variable mechanism 35 is not provided.SELECTED DRAWING: Figure 24
