In this state, when the slide door and the swing door are not locked, the first lock portion is restrained by the restraining means, so that the engagement between the first lock portion and the first receiving portion is released. It becomes impossible. For this reason, since it becomes impossible to unlock the swing door and the vehicle body, the swing door cannot be opened. On the other hand, when the sliding door and the swing door are locked, since the restraint of the first lock portion by the restraining means is released, the engagement between the first lock portion and the first receiving portion can be released. For this reason, since it becomes possible to cancel | release the locked state of a swing door and a vehicle body, a swing door can be opened. Thus, according to the present invention, the swing door cannot be opened when the slide door and the swing door are not completely locked.

  Preferably, the restraining means includes a main member having an engagement portion that engages with the first lock portion, and an elastic body that biases the main member in a direction of restraining the first lock portion by the main member. One end of the member forms a lock detection unit that detects the lock between the slide door and the swing door. In such a configuration, when the lock detection unit does not detect the locked state of the slide door and the swing door, the engagement portion of the main member is engaged with the first lock portion by the urging force of the elastic body, 1 lock part is restrained by the main member. On the other hand, when the lock detection unit detects the locked state of the slide door and the swing door, the engagement between the main member engagement portion and the first lock portion is released against the biasing force of the elastic body. It becomes a state and the restraint of the first lock portion by the main member is released.

  At this time, the engaging portion is preferably a hook portion that is hooked to the first lock portion. In this case, since the first lock portion is restrained by hooking the hook portion of the main member to the first lock portion, the restraining means can be realized with a simple structure.

  Preferably, the lock detection unit detects the lock between the slide door and the swing door by contacting the slide door. In this case, the sliding state of the sliding door and the swing door can be reliably detected by the sliding door coming into contact with the lock detection portion of the main member.

  At this time, the second lock means has a second lock portion provided on the slide door, and a second receiving portion provided on the swing door and engaged with the second lock portion. It is preferable to detect the lock between the sliding door and the swing door by contacting the two lock portions. In this case, when the second lock part itself constituting a part of the second lock means contacts the lock detection part of the main member, it is detected that the slide door and the swing door are in the locked state. . Therefore, the locked state of the slide door and the swing door can be detected with high accuracy.

  According to the present invention, it is possible to provide a vehicle door structure that prevents the swing door from being opened when the sliding door and the swing door are not completely locked. As a result, it is possible to prevent the sliding door from rattling and the sliding door from moving while the swing door is rotating.

Therefore, the swing door 7 does not rotate together with the slide door 6. However, if the malfunction that the state where the engagement between the lock member 28 and the striker 29 is released is maintained when the swing door handle 10 is operated, the sliding door 6 may be rattled. is there.

  Therefore, in order to solve such a problem, the vehicle door structure 1 of the present embodiment further includes a lock member restraining mechanism 40 (restraining means) as shown in FIG. In FIG. 1, the lock member restraining mechanism 40 is omitted. The lock member restraining mechanism 40 is provided in the vicinity of the lock member 32 of the swing door lock mechanism 27 at the upper and lower parts of the swing door 7.

  The lock member restraining mechanism 40 prevents the lock member 32 from moving in the vertical direction of the swing door 7 when the lock door 32 is engaged with the striker 33 and the swing door 7 and the vehicle body 2 are locked. When the lock member 32 is restrained, the lock between the swing door 7 and the vehicle body 2 cannot be released, and when the slide door 6 and the swing door 7 are locked by the fully-open slide door lock mechanism 26, It is a mechanism that allows the swing door 7 and the vehicle body 2 to be unlocked by releasing the restraint of the lock member 32.

  The lock member restraining mechanism 40 has a substantially J-shaped rod member 41 (main member) extending in the front-rear direction of the swing door 7. One end portion (front end portion) of the rod member 41 forms a lock detection portion 42 that detects the lock between the slide door 6 and the swing door 7. The lock detector 42 protrudes forward from the front end of the swing door 7. The other end portion of the rod member 41 is a hook portion 43 (engagement portion) that engages with the lock member 32 by being caught by the lock member 32. The rod member 41 is supported by a support plate 44 attached to the swing door 7 so as to be movable in the front-rear direction of the swing door 7.

  Further, the lock member restraining mechanism 40 has a spring 45 (elastic body) that biases the rod member 41 on the front side of the swing door 7 so that the lock member 32 is restrained by the rod member 41. One end of the spring 45 is connected to an auxiliary portion 41 a provided on the rod member 41, and the other end of the spring 45 is connected to the support plate 44.

  The lock member 30 of the fully open slide door lock mechanism 26 is attached to the front end portion of the slide door 6 via a lock base 46. The lock member 30 is provided with a protrusion 47 that abuts (engages) with the lock detection portion 42 of the rod member 41.

  In such a lock member restraining mechanism 40, when the slide door 6 is closed and the slide door 6 and the swing door 7 are not locked, the spring 45 is attached as shown in FIG. The hook portion 43 of the rod member 41 is caught by the lock member 32 by the force, and the lock member 32 is restrained. For this reason, as shown in FIG. 3, even if an operation of opening the swing door 7 by the swing door handle 10 is performed, the lock member 32 is not pulled through a cable (not shown). Does not move to the center in the vertical direction of the swing door 7. Accordingly, since the locked state of the swing door 7 and the vehicle body 2 is not released, the swing door 7 cannot be opened.

  On the other hand, when the slide door 6 is fully opened, the protrusion 47 provided on the lock member 30 hits the lock detection portion 42 of the rod member 41 to push in the rod member 41 as shown in FIG. It is detected that the swing door 7 is locked. At this time, the protrusion 47 is provided on the lock member 30 that engages with the striker 31. For this reason, the detection precision of the lock | rock with the slide door 6 and the swing door 7 becomes high.

  When the slide door 6 and the swing door 7 are in the locked state, the rod member 41 moves to the rear side of the swing door 7 against the biasing force of the spring 45, so that the lock member 32 of the rod member 41 is locked by the hook 43. The constraint is released. Therefore, as shown in FIG. 3, when the swing door handle 10 is used to open the swing door 7, the lock member 32 resists the biasing force of a spring (not shown) via a cable (not shown). And pulled. Therefore, since the locked state of the swing door 7 and the vehicle body 2 is released, the swing door 7 can be opened.

  As described above, in the present embodiment, when the slide door 6 is opened, the lock member 32 is locked by the hook portion 43 of the rod member 41 when the slide door 6 and the swing door 7 are not completely locked. Therefore, even if the handle 10 for the swing door is operated, the swing door 7 cannot be opened. Further, when the sliding door 6 and the swing door 7 are not completely locked, when the swing door handle 10 is operated, the lock between the swing door 7 and the vehicle body 2 does not become incomplete. . As described above, rattling of the slide door 6 can be prevented.

  In the present embodiment, the protrusion 47 that contacts the lock detection portion 42 of the rod member 41 is provided on the lock member 30. However, the present invention is not limited to this configuration. For example, as shown in FIG. The portion 47 may project from the lock base 46. Further, the protrusion 47 may be provided in a projecting manner on another part provided on the slide door 6.

  FIG. 6 is a plan view (including a partial cross section) showing a modified example of the lock member restraining mechanism 40 as another embodiment of the vehicle door structure according to the present invention.

  In the figure, the lock member restraining mechanism 40 of this modification has a plate-like member 51 (main member) extending in the front-rear direction of the swing door 7. One end portion (front end portion) of the plate-like member 51 forms a lock detection portion 52 that detects the lock between the slide door 6 and the swing door 7.

  The plate-like member 51 is formed with a notch portion 54 into which the protrusion 53 provided on the lock member 32 enters. The protrusion 53 has a rectangular cross section and is provided on the outer surface of the lock member 32. The notch 54 has a rectangular cross section corresponding to the protrusion 53. The width dimension of the notch 54 is slightly larger than the width dimension of the protrusion 53. The plate-like member 51 is arranged so as to be shifted in the vertical direction of the swing door 7 with respect to the protrusion 53. A portion of the plate-like member 51 where the notch 54 is not formed forms an engaging portion that engages with the lock member 32.

  The lock member restraining mechanism 40 includes a spring 55 (elastic body) that biases the plate member 51 toward the front side of the swing door 7 so as to restrain the lock member 32 by the plate member 51. One end of the spring 55 is connected to the other end (rear end) of the plate-like member 51, and the other end of the spring 55 is connected to a support plate 56 attached to the swing door 7. Other configurations are the same as those of the above-described embodiment shown in FIG.

  In such a lock member restraining mechanism 40, when the slide door 6 is closed and the slide door 6 and the swing door 7 are not locked, the spring 55 is attached as shown in FIG. The notch 54 of the plate-like member 51 is in a position displaced from the protrusion 53 of the lock member 32 due to the force, and the lock member 32 is restrained. For this reason, as shown in FIG. 3, even if it tries to pull the lock member 32 via a cable (not shown) by performing an operation of opening the swing door 7 by the handle 10 for the swing door, the protruding portion 53 is a plate. The lock member 32 does not move toward the center in the vertical direction of the swing door 7 because it is caught by the member 51. Accordingly, since the locked state of the swing door 7 and the vehicle body 2 is not released, the swing door 7 cannot be opened.

  On the other hand, when the slide door 6 is fully opened, as shown in FIG. 6B, the protrusion 47 provided on the lock member 30 hits the lock detection portion 52 of the plate member 51 to push the plate member 51 into the slide. It is detected that the door 6 and the swing door 7 are locked. Then, the plate member 51 moves to the rear side of the swing door 7 against the urging force of the spring 55 so that the position of the notch 54 of the plate member 51 coincides with the position of the protrusion 53 of the lock member 32. Thus, the restraint of the lock member 32 by the plate-like member 51 is released. Therefore, as shown in FIG. 3, when the swing door handle 10 is used to open the swing door 7, the lock member 32 resists the biasing force of a spring (not shown) via a cable (not shown). And pulled. Therefore, since the locked state of the swing door 7 and the vehicle body 2 is released, the swing door 7 can be opened.

  Thus, in this embodiment, when the slide door 6 is opened, the lock member 32 is restrained by the plate-like member 51 in a state where the slide door 6 and the swing door 7 are not completely locked. Even if the handle 10 for the swing door is operated, the swing door 7 cannot be opened.

  In the present embodiment, the protrusion 53 that enters the notch 54 of the plate-like member 51 is provided on the lock member 32, but the configuration is not particularly limited. For example, a slit may be formed in the lock member 32. . In this case, when the cutout portion 54 is at a position shifted from the slit portion, the lock member 32 is constrained by the plate-like member 51, and when the position of the cutout portion 54 matches the position of the slit portion. In this state, the restraint of the lock member 32 by the plate member 51 is released.
