The lower surface of the tip side portion of the base plate 26 preferably has a tapered portion 26b that tapers toward the tip of the base plate 26 as shown in FIG.

  Further, as shown in FIG. 7, the lock mechanism 23 has a latch part advance / retreat mechanism 31 that advances and retracts each latch part 28 with respect to both side surfaces of the base plate 26. In FIG. 7, the base plate 26 is shown in a simplified manner, and the tapered portion 26a is omitted.

  The latch part advancing / retreating mechanism 31 has a pair of arm members 32 arranged in a cross shape inside the base plate 26. Each arm member 32 is rotatably supported by the base plate 26 via a shaft portion 33. The latch portion 28 is provided at the distal end portion of the arm member 32. The base plate 26 is formed with an opening window (not shown) for causing the latch portions 28 to advance (protrude).

  Between the base end part of each latch part 28 and the side edge part of the base plate 26, the spring 34 which urges | biases each latch part 28 to the both sides | surfaces of the base plate 26 (direction A in the drawing) is respectively provided. It is connected. The spring 34 is disposed so as to expand and contract along the width direction of the base plate 26 (the arrangement direction of the latch portions 28).

  The base end portion of each arm member 32 and the outer door opening / closing handle 8 and the inner door opening / closing handle 9 are connected by a cable 35. The cable 35 is connected to the base end portion of each arm member 32 in a Y-shaped state.

  In the vehicle door structure 1 configured as described above, when the slide door 6 is slid to the rear side of the vehicle body 2, the slide door 6 is fully opened and the slide door 6 and the swing door 7 overlap each other. The load of the slide door 6 is transferred from the vehicle body 2 to the swing door 7. Thereby, the swing door 7 can be opened and closed while the slide door 6 is supported.

  When the sliding door 6 and the swing door 7 are locked by the lock mechanism 23 when the sliding door 6 is fully opened, the base plate 26 is moved by the sliding movement of the sliding door 6 as shown in FIG. Insert inside.

  At this time, as described above, since both side surfaces and the lower surface of the tip side portion of the base plate 26 have the taper portions 26a and 26b, the variation in the width direction and the height direction of the slide door 6 is absorbed, The base plate 26 can be easily put into the positioning part 29 of the striker 27.

  When the base plate 26 enters the positioning portion 29, the inclined surface 28 b of each latch portion 28 is pushed by the opening edge of the striker 27, so that each latch portion 28 resists the biasing force of the spring 34 and enters the base plate 26. It is in the retracted (retracted) state. When the base plate 26 passes through the positioning portion 29, as shown in FIGS. 3B and 7A, each latch portion 28 advances from the side surface of the base plate 26 by the biasing force of the spring 34, and each latch portion. 26 is hooked on each latch receiving surface 30. As a result, the base plate 26 is locked to the striker 27, and as a result, the slide door 6 and the swing door 7 are locked.

  When unlocking the slide door 6 and the swing door 7 by the lock mechanism 23, an operation of closing the slide door 6 by the outer door opening / closing handle 8 or the inner door opening / closing handle 9 is performed. Then, as shown in FIG. 7B, since the cable 35 is pulled, each arm member 32 is rotated, and each latch portion 28 is retracted into the base plate 26 against the urging force of the spring 34. Thus, the base plate 26 is extracted from the striker 27. Thereby, the lock | rock of the slide door 6 and the swing door 7 is cancelled | released, and it becomes possible to close the slide door 6. FIG.

  Here, an example of a conventional locking mechanism is shown in FIG. The lock mechanism 100 shown in FIG. 8 includes a base plate 101 attached to a slide door (not shown), a latch portion 102 provided on the upper portion of the base plate 101, and a swing door 103 attached to the latch portion 102. It has a striker 104 to be joined, and a roller 105 attached to the swing door 103 and guiding the base plate 101. The latch portion 102 is covered with a cover 106. The striker 104 and the roller 105 are also covered with a cover (not shown).

  However, the lock mechanism 100 requires many parts such as the base plate 101, the latch portion 102, the striker 104, the roller 105, the cover 106, and the like. For this reason, the lock mechanism 100 is complicated, enlarged, and increased in cost. In addition, since there is a backlash in the width direction between the latch portion 102 and the striker 104, variation in the relative position between the sliding door (not shown) and the swing door 103 is increased. Furthermore, since the load in the vertical direction of the sliding door is received by the roller 105 via the base plate 101, it becomes difficult to stably support the sliding door, and the variation in the relative position of both doors further increases. .

  On the other hand, in this embodiment, a pair of left and right latch portions 28 are provided on the base plate 26 attached to the slide door 6 so as to be able to advance and retreat, and the striker 27 disposed in the swing door 7 is associated with each latch portion 28. Since the paired left and right latch receiving surfaces 30 are provided, the roller 105 and the cover 106 are not necessary, and the number of parts of the lock mechanism 23 can be reduced. Thereby, simplification and size reduction of the lock mechanism 23 can be achieved, and as a result, cost reduction can be achieved.

  In addition, since the pair of latch portions 28 can move forward and backward with respect to the base plate 26 and the striker 27 is disposed in the swing door 7, the appearance of the lock mechanism 23 can be improved. Moreover, space efficiency can be improved by arrange | positioning the striker 27 in the swing door 7. FIG.

  Further, since the striker 27 is provided with the positioning portion 29 for positioning and restraining the base plate 26 in the height direction and the width direction with respect to the striker 27, the position variation in the height direction and the width direction between the base plate 26 and the striker 27 is almost no. In addition, the relative positional accuracy of the sliding door 6 and the swing door 7 when they are locked can be increased.

  Further, since the positioning portion 29 of the striker 27 has the lower inner wall surface 29b, the load in the vertical direction of the slide door 6 is received by the lower inner wall surface 29b via the base plate 26 by surface contact. Thereby, the load in the vertical direction of the slide door 6 is dispersed and the relative positional accuracy in the vertical direction between the slide door 6 and the swing door 7 is further improved, so that the slide door 6 is stably supported by the swing door 7. Can do. Further, since the base plate 26 is disposed in a laid state, the load in the vertical direction of the slide door 6 is received on a large surface. Therefore, it is advantageous when the load of the slide door 6 is large.

  FIG. 9 is a view showing a modified example of the latch part advance / retreat mechanism 31 as another embodiment of the vehicle door structure according to the present invention. In the figure, the same or equivalent elements as those in the embodiment described above are denoted by the same reference numerals, and the description thereof is omitted. In FIG. 9, the base plate 26 is shown in a simplified manner, and the tapered portion 26a is omitted.

  In this figure, the latch part advance / retreat mechanism 31 of this modification has a trapezoidal intermediate member 50 disposed between the latch parts 28 inside the base plate 26. The opposing surfaces of the intermediate member 50 on the side of each latch portion 28 are tapered surfaces 51 that taper toward the tip of the base plate 26. The surface on the intermediate member 50 side of each latch portion 28 has a tapered surface 52 corresponding to the tapered surface 51 of the intermediate member 50. The tapered surfaces 51 and 52 are in contact with each other.

  A spring 53 is connected between the intermediate member 50 and the tip of the base plate 26 to bias the tip of the base plate 26 toward the tip (B direction in the drawing). The spring 53 is arranged so as to expand and contract along a direction (front-rear direction of the base plate 26) perpendicular to the width direction of the base plate 26 (the arrangement direction of the latch portion 28 and the intermediate member 50).

  Between each latch part 28 and the side edge part of the base plate 26, the spring 54 which urges | biases each latch part 28 in the direction (C direction shown in the figure) which retracts in the base plate 26 is connected, respectively. The spring 54 is connected between the latch portion 28 and a side edge portion located on the opposite side of the latch portion 28 with respect to the intermediate member 50 in the base plate 26. The spring 54 is disposed so as to expand and contract along the width direction of the base plate 26.

  The intermediate member 50 is connected to the outer door opening / closing handle 8 and the inner door opening / closing handle 9 by the cable 35 described above.

  In a state where the slide door 6 and the swing door 7 are locked, the intermediate member 50 is in an initial position corresponding to the urging force of the spring 53 as shown in FIG. At this time, each latch portion 28 has advanced from the side surface of the base plate 26 against the urging force of the spring 54.

  When the cable 35 is pulled by performing the operation of closing the slide door 6 with the outer door opening / closing handle 8 or the inner door opening / closing handle 9, the intermediate member 50 is subjected to the biasing force of the spring 53 as shown in FIG. Accordingly, the base plate 26 moves from the initial position to the base end side. At this time, since each tapered surface 51 of the intermediate member 50 slides along the tapered surface 52 of each latch portion 28, each latch portion 28 is retracted into the base plate 26 by the biasing force of the spring 54.

  The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the base plate 26 constituting a part of the lock mechanism 23 is disposed in a lying state, and the latch portions 28 are provided on both the left and right sides of the base plate 26 so as to be able to advance and retract.
