In general, a vehicle has a vehicle compartment having a predetermined size capable of accommodating a driver and a fellow rider, and a vehicle compartment opening/closing door is provided in the vehicle body to open or close the vehicle compartment.

In the case of a passenger vehicle, the vehicle compartment opening/closing door includes a front door provided in the front in the longitudinal direction of the vehicle and a rear door provided in the rear in the longitudinal direction of the vehicle, and the front door and the rear door are usually rotatably provided in the vehicle body by hinges.

In the case of a van which may accommodate many people, the vehicle compartment opening/closing door slides back and forth in the longitudinal direction of the vehicle to open or close the vehicle compartment.

In the sliding-type vehicle compartment opening/closing door of the van, the vehicle compartment opening/closing door moves rearward in the longitudinal direction of the vehicle to open the vehicle compartment, and moves forward in the longitudinal direction of the vehicle to close the vehicle compartment. Therefore, it is advantageous in that the opening/closing space required for opening and closing the door is smaller than that of the hinge-type vehicle compartment opening/closing door such as the passenger vehicle, and the door opening formed in the vehicle body may be completely opened even in a narrow opening/closing space.

On the other hand, the door of the vehicle is provided with a door armrest for supporting the arm of the occupant. However, as shown in FIG. 1, in the vehicle including sliding compartment opening/closing doors 2 and 3 on a vehicle body 1, it is difficult to secure the space occupied by the door armrest on the rear door 3 side to secure the swing gap G. FIG. 2 is an enlarged view showing a part ‘A’, which is a vehicle hinge coupling portion of FIG. 1, and FIG. 3 is a cross-sectional view cut along a line ‘B-B′ of FIG. 2.

As shown in FIG. 2 and FIG. 3, in a case of the hinge-type compartment opening/closing door, in the space between the rear door 3 and the luggage trim 5, as there is no choice but to reduce an existing armrest length space to produce a smaller length space to avoid interference when opening the door, the space is reduced by an ‘L’ length compared to an existing one. In the instant case, there is a problem that usability deteriorates because it is difficult for the occupant to secure an armrest space to support the arm.

The information included in this Background of the present disclosure is only for enhancement of understanding of the general background of the present disclosure and may not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
