In this state, as shown in FIG. 7C, the arm cover 91 abuts against the load support arm 18, swings the swing end forward, and the front side of the swing end is covered with the side cover 75. At this time, the swing end 756 of the side cover 75 contacts or approaches the door trim 80, and the door knob 56 protruding from the inner wall surface of the rear door 4 approaches or contacts a part of the swing end 756.

In this state, the gap E and the swing slide unit U can be stably covered from the front, and foreign objects and passengers entering the gap E and the swing slide unit U can be prevented, thereby ensuring safety.
In this state, even if the occupant intentionally pulls the side cover 75 to the front side, the door knob 56 functions as a stopper and is prevented from swinging to the front side from the cover position K2 and being displaced. In this way, even if the side cover 75 that is only elastically rotated and biased toward the covering position K2 is intentionally pulled forward, the door knob 56 functions as a stopper of the side cover 75, and the door The gap E between the inner wall and the outer wall of the vehicle body can be covered stably and reliably from the front, ensuring aesthetics, and reliably preventing foreign objects and passengers from entering the swing slide unit U and the swing slide unit U. Can be secured.

Next, it is assumed that the controller 30 receives a door closing command.
In this case, the motor M of the door-side drive mechanism 19 is driven and reversely operates in the state shown in FIGS. 6B and 6A. In this closing operation, the side cover 75 and the arm cover 91 are opened. It swings in the opposite direction of operation. Further, when the rear door 4 reaches the half latch position immediately before the closing position D1, the opening / closing control unit 301 stops the motor M of the door side drive mechanism 19.
Next, the latch drive controller 302 drives a motor (not shown) of the latch drive means 191 to fully latch the front end upper lock portion J1, the front end lower lock portion J2, and the rear end lock portion J3 of the rear door 4, and close the rear door 4. Hold at position D1.

As a result, the rear door 4 holds the closed position D1, the side cover 75 is held at the overlapping position K1, and the side cover 75 and the arm cover 91 overlap the door trim 80, eliminating the uncomfortable feeling without narrowing the passenger compartment width. It is possible to secure aesthetics.
In the above description, the door knob 56 has been described as a rotation restricting member that abuts the swinging end of the side cover 75 and covers the side cover 75 and holds it at the position K2. As shown in (b), a door handle 58 or a cup holder 59 may be attached to the upper and lower intermediate portions of the front edge of the door trim 80 as a rotation restricting member.

  Here, as shown in FIG. 9A, when the door handle 58 is used, the door handle 58 is formed in the handle substrate portion 581 and the handle substrate portion 581 so as to protrude vertically into the I-shape in front view. The projecting cover portion 582 and the opening gripping portion 583 and the closing gripping portion 584 are assembled in a state of being opposed to each other so as to be retractable from the left and right side walls of the projecting cover portion 582. The open gripping portion 583 and the closing gripping portion 584 are respectively pushed into the center side of the protruding cover portion 582 so that the open / close switch portions 585 and 586 can be switched from the off state to the on state. Note that the handle substrate portion 581 is in contact with the swinging end of the side cover 75 and has a function as a rotation restricting member that covers the side cover 75 and holds it at the position K2.

  Here, the open / close signals of the open / close switch sections 585 and 586 are output to the controller 30 in the same manner as the open / close signal of the door open / close switch (door open / close operation means) SW1 provided in the rear door 4 of FIG. In addition, the opening / closing control unit 301, the latch drive control unit 302, and the latch release control unit 303 perform control functions, and the same opening / closing control as that of the rear door of FIG. 1 is performed. In addition, when the occupant applies a pressing force Fo to the open gripping portion 583 and applies an operating force that exceeds the sliding resistance of the rear door 4 in the rearward direction when the opening / closing control unit 301 is not controlled, the rear door 4 is unlocked. When the occupant in the vehicle applies a pressing force Fc to the closing grip 584 and an operating force exceeding the sliding resistance of the rear door 4 in the forward direction, the rear door 4 is locked. Along with the release, it can slide in the forward direction, that is, in the closing direction.

In addition, when the rear door 4 (similar to the door trim 80) reaches the fully open position D3 and the side cover 75 is held at the cover position K2, the door handle 58 comes into contact with the swinging end of the side cover 75 and functions as a stopper. Therefore, the side cover 75 can be intentionally pulled and can be reliably restricted from being removed from the cover position K2, and the number of parts can be reduced.
As shown in FIG. 9B, when the cup holder 59 is used, the cup holder 59 projects into a board portion 591 that is fastened to an inner panel (not shown) via a door trim 80 so that the cup holder 59 can be accommodated in the board portion 591. And a cup receiving portion 592 provided.
Also in this case, when the rear door 4 reaches the fully open position D3 and the side cover 75 is held at the cover position K2, the cup receiving portion 592 held in the storage state (the state of the two-dot chain line) is Abutting on the moving end and functioning as a stopper, the side cover 75 can be intentionally pulled and released from the covering position K2 can be reliably prevented as a rotation restricting member, and the number of parts can be reduced.

In the above description, the rear door 4 has been described as swinging from the closed position on the front side by the swing slide unit U to reach the protruding position, and then slides to the fully open position on the rear side. The present invention can be applied to a structure in which the illustrated swing slide door reaches a protruding position in front of the closed position and further reaches a fully open position in front of the closed position. An effect is obtained.
In the above description, the present invention is described as being applied to the rear door 4 that is a swing slide door. However, the present invention includes two rails attached to the top and bottom of the door and a third rail at the rear center portion of the outer wall of the vehicle body.
