  Around the rear entrance / exit 3, a plurality of lock portions J <b> 1, J <b> 2, J <b> 3 for holding the rear door 4 are disposed at a door closing position D <b> 1 that closes the rear entrance / exit 3. In the present embodiment, each lock portion has a lock portion J1, J2 located on the front side (closed direction side) of the rear entrance / exit 3 located on the front door side, and a lock portion J3 is located on the rear side (opening side) of the rear entrance / exit 3 ). That is, at the door closing position D1, as shown in FIG. 5, the rear door 4 is releasably locked to the roof side rail 10 using the latch 120B and the striker 121B constituting the front end upper lock portion J1, and the front end lower lock As shown in FIG. 6, the portion J2 is removably locked to the side sill 101 using a latch 125B and a striker 126B. Further, the rear end lock portion J3 is removably locked to the rear pillar 102 using a latch 122 and a striker 123 as shown in FIG.

  In this embodiment, the strikers 121A and 121B of the upper lock portions i1 and J1 are fastened and fixed to the roof side rail 10 with bolts 103A and 103B, and the strikers 126A and 126B of the lower lock portions i2 and J2 are attached to the outer panel of the side sill 101. It is fastened and fixed with bolts (not shown). The striker 123 of the rear end lock portion J3 is fastened and fixed to the outer panel of the rear pillar 102 with bolts 104. The latches of the respective lock portions are respectively fixed to the inner panels 21A and 21B of the front door 2 and the rear door 4 that face each striker.

  In this embodiment, as shown in FIG. 1, the lock parts i1 and i2 are trapezoids having a line connecting the lock parts i1 and i2 together with the hinge parts h1 and h2 as a base and a line connecting the hinge parts h1 and h2 as an upper side. It arrange | positions at the periphery of the front entrance / exit 1 so that the area | region M1 may be formed. The lock portions J1, J2, and J3 are arranged on the periphery of the rear entrance 3 so that a line connecting the lock portions forms a triangular area M2 having the lock portion J3 as a vertex.

  The lock portions i1 and i2 and the lock portions J1 and J2 are arranged so that the interval L2 between the lower lock portion i2 and the lock portion J2 is larger than the interval L1 between the upper lock portion i1 and the lock portion J1. In addition, when the front door 2 and the rear door 4 are closed, a region M3 is formed between the regions M1 and M2. In this region M3, the lower side surrounded by the line connecting the lock parts i1 and i2, the line connecting the lock parts J1 and J2, the line connecting the lock parts i1 and J1, and the line connecting the lock parts i2 and J2 is from the upper side. It forms a wide trapezoid and functions as a center pillar region when the front door 2 and the rear door 4 are closed. That is, when the front door 2 and the rear door 4 are fixed to the door opening by the lock portions i1, i2 and the lock portions J1, J2, the portions of the doors located in the region M3 function as center pillars.

  As described above, the lock portions i1 and i2 that hold the front door 2 in the closed position that closes the front entrance / exit 1 serving as the door opening are arranged on the upper and lower sides of the front entrance / exit 1 and the rear entrance 3 is closed. Since the lock portions J1, J2 and J3 for holding the slide type rear door 4 at D1 are arranged on the front upper and lower sides and the rear side of each entrance / exit 3 respectively, the front entrance / exit 1 and the rear entrance 3 are connected to the front door 2 and the rear door. When closed at 4, these doors are independently held by the individual lock portions i1, i2 and lock portions J1, J2, J3, so that the door opening / closing sequence does not occur, and the front door 2 and the rear door 4 can be firmly held. As a result, the center pillar-less structure can increase rigidity and effectively prevent inadvertent opening of the door when an impact load is applied from the side of the vehicle. And increased rigidity. Further, since the front door 2 is held at the closed position where the front entrance / exit 1 is closed at four points of the trapezoidal region M1 connecting the hinge portions h1 and h2 and the lock portions i1 and i2, the locked state of the door alone is stabilized.

  In particular, in the rear door 4, since the vicinity of the center of gravity of the slide door is supported by the swing slide unit U in the region surrounded by the lock portions, the front door is closed when the rear door 3 is closed by the rear door 4. Since the upper and lower lock portions J1 and J2 and the lock portion J3 on the rear side of the door are held in the closed state, generation of a rotational moment in the closed state is suppressed. For this reason, the locked state of the rear door 4 can be kept strong while reducing the occurrence of vibration at the closed position, and the door can be effectively prevented from being opened unexpectedly when an impact load is applied from the side of the vehicle. Can do. Moreover, since the lock portions J1, J2, and J3 are arranged on the periphery of the rear entrance 3 so as to form a triangular region M2 having the lock portion J3 as a vertex, the rear door 4 can be efficiently closed with a small number of lock portions. Since it can hold | maintain in the position D1, cost reduction can be aimed at.

  By supporting the vicinity of the central portion of the rear door 4 that is a sliding door in the vertical direction with the swing slide unit U, there is no need to install a slide rail or the like in the side roof rail 10 or the side sill 101 as in the prior art. 10 and the side sill 101 become smaller in cross section, the height restriction of the front entrance / exit 1 and the rear entrance / exit 4 and the protrusion to the vehicle interior are reduced, so that the passenger can get on and off more easily.

  Each of the lock portions i2 and J2 arranged at the lower portion in the closing direction of the front entrance / exit 1 and the rear entrance 4 is wider than the interval L1 between the lock portions i1 and J1 arranged at the upper portion in the closing direction. Since the lock portions are arranged, the virtual sensor pillar region M3 is formed by the region connecting the lock portions. In this center pillar region, since the lower part is widened, the contact area with the collision object is increased, and the impact load can be efficiently distributed to the front door 1 and the rear door 4. Moreover, since the width | variety is hold | suppressed above the center pillar area | region M3, an occupied surface, such as a window, can be taken widely, visibility can improve and safety can improve more.

  Next, the restraint between the front door 2 and the rear door 4 by the lock portion will be described. In this embodiment, as shown in FIGS. 5 and 6, the door restraining directions by the lock portions i1 and J1 arranged at the upper portion in the closing direction and the lock portions i1 and J1 arranged at the lower portion in the closing direction are different from each other. Each lock part is arranged so that That is, in this embodiment, the mounting directions of the strikers 121A and 121B of the lock portions i1 and J1 and the strikers 126A and 126B of the lock portions i2 and J2 are different.

  As shown in FIG. 5, the strikers 121A and 121B are mounted on the side roof rail 10 so as to be substantially horizontal and wide in the vehicle front-rear direction X, and the latches 120A and 120B are arranged in the vertical direction with respect to the striker. It is attached to each door so as to mesh with each other. On the other hand, as shown in FIG. 6, the strikers 126A and 126B are mounted so as to be substantially perpendicular to the side sill 101 and wide in the vehicle width direction Y, and the latches 125A and 125B are engaged with each other so as to be engaged from the horizontal direction. It is attached to the door.

  Therefore, in the locked state of the lock portions i1 and J1, the movement of the latches 121A and 121B is restricted with respect to the vertical direction of the vehicle indicated by the arrow Z in FIG. It becomes. In the locked state of the lock portions i2 and J2, the latches 126A and 126B can move in the vertical direction of the vehicle indicated by the arrow Z, but the movement is restricted in the vehicle width direction Y.

  For this reason, even when the positional relationship between the latches and the strikers of the respective lock portions is shifted due to the opening / closing operation of the front door 1 or the rear door 4, the shift can be absorbed, so that the installation of the door can be easily adjusted. Further, the locked state of each door can be held more strongly, and inadvertent opening of the door when an impact load is applied can be prevented more reliably. In particular, the support structure of the rear door 4 of this embodiment is a structure in which the vicinity of the center portion in the vertical direction is supported by the swing slide unit U, so that a rotational moment in the upper limit direction is easily generated with the opening and closing operation, and the installation system Although it is difficult to remove, the direction of restraint between the upper lock portion J1 and the lower lock portion J2 is different, so that installation adjustment can be easily performed.
