  However, the following problems exist in the prior art. That is, when performing the installation adjustment of the slide door, the arrangement position of the slide door with respect to the vehicle body is adjusted by adjusting the mounting position of the striker with respect to the vehicle body. However, in the above-described conventional vehicle door structure, the striker is disposed obliquely with respect to the front-rear direction and the left-right direction of the vehicle body. For this reason, if it is going to adjust the position of the striker along the left-right direction of a vehicle body, the position of the striker along the front-back direction of a vehicle body will also change. For this reason, it becomes difficult to perform the installation adjustment of the slide door.

  The objective of this invention is providing the vehicle door structure which can perform the installation adjustment of a slide door easily.

  One aspect of the present invention is for a vehicle including a slide door that opens and closes a door opening provided in a vehicle body, and a lock unit that locks the slide door with respect to the vehicle body when the slide door is in a fully closed state. In the door structure, the lock unit is mounted on a striker having a locked portion that is attached to a plane perpendicular to the front-rear direction or the left-right direction of the vehicle body and extends in a direction parallel to the front-rear direction of the vehicle body, and is rotatably mounted on the slide door. And a latch that sandwiches and locks the locked portion of the striker, the latches are arranged so as to face each other in parallel, and have two clamping surfaces that sandwich the locked portion. The latch is inclined with respect to the rotation axis of the latch so that the latch is parallel to the locked portion in a state where the locked portion of the striker is sandwiched and locked.

  As described above, in the vehicle door structure according to the present invention, the two sandwiching surfaces of the latch are arranged so as to face each other in parallel, and the latch sandwiches and locks the locked portion of the striker. Is inclined with respect to the rotation axis of the latch so as to be parallel to the locked portion. For this reason, since the locked portion of the striker extends in a direction parallel to the front-rear direction of the vehicle body, the moving direction of the latch when the sliding door is fully closed is relative to the extending direction of the locked portion. Even if it is inclined, the locked portion can be sandwiched and locked by the latch. Here, since the striker is attached to the front-rear direction or the vertical direction of the left-right direction of the vehicle body, when adjusting the installation position of the striker, without changing the position of the striker along the front-rear direction of the vehicle body, It is possible to adjust the position of the striker along the left-right direction. Thereby, the installation adjustment of a slide door can be performed easily.

  The striker may be attached to a surface perpendicular to the front-rear direction of the vehicle body. In this case, it is possible to easily adjust the position of the striker along the left-right direction of the vehicle body only by moving the striker in the left-right direction of the vehicle body without using a spacer for adjusting the mounting position. .

  An R chamfered portion may be provided at the edge of the sandwiching surface. In this case, when the latched portion is sandwiched and latched by the latch, the edge portion of the sandwiching surface of the latch is prevented from hitting the latched portion and being damaged.

The left-right direction of the vehicle body 2 is a direction perpendicular to the front-rear direction and the vertical direction (height direction) of the vehicle body 2. The front side end surface 7a is a surface orthogonal to the front side outer surface 7b.

  The striker 25 is attached to the front end face 7 a of the swing door 7. The striker 25 includes a base 30 fixed to the front side end surface 7 a and a substantially U-shaped striker body 31 integrated with the base 30. The striker body 31 is formed by bending a round bar into a substantially U shape. The striker body 31 has a locked portion 32 that extends in a direction parallel to the front-rear direction of the vehicle body 2 and engages with the lock member 24 when the swing door 7 is fully closed. Here, the direction parallel to the front-rear direction of the vehicle body 2 includes not only a direction completely parallel to the front-rear direction of the vehicle body 2 but also a direction substantially parallel to the front-rear direction of the vehicle body 2.

  As shown in FIG. 4, the lock member 24 includes a lock base 33, a latch 34, a pole 35, and a cover 36. In FIG. 3, only the latch 34 is shown for simplification. The lock base 33 is fixed to the rear end portion of the slide door 6. On the lock base 33, shaft pins 37, 38 are projected with a predetermined interval.

  The latch 34 is rotatably attached to the lock base 33 via a shaft pin 37. Accordingly, the latch 34 is rotatably attached to the slide door 6. As shown in FIG. 3, the latch 34 sandwiches and locks the locked portion 32 of the striker 25. The latch 34 is urged in a predetermined direction by a spring (not shown).

  The pole 35 is rotatably attached to the lock base 33 via a shaft pin 38. The pole 35 restricts the rotation of the latch 34 relative to the lock base 33 so that the latch 34 maintains the state where the latched portion 32 of the striker 25 is sandwiched. The cover 36 is assembled to the lock base 33 so as to cover the latch 34 and the pole 35.

  5A is a plan view of the latch 34, FIG. 5B is a front view of the latch 34, and FIG. 5C is a cross-sectional view taken along line 5c-5c in FIG. 5A. is there. In each figure, the latch 34 is formed with a through hole 39 having a circular cross section through which the shaft pin 37 of the lock base 33 passes. The latch 34 is provided with a protrusion 40 that engages with the pole 35.

  Further, the latch 34 is formed with a notch 41 for sandwiching the locked portion 32 of the striker 25. The latch 34 is disposed so as to face each other in parallel, and has two sandwich surfaces 42 and 43 that sandwich the locked portion 32, and a curved surface 44 that is disposed so as to be connected to the sandwich surfaces 42 and 43. doing. The sandwiching surfaces 42 and 43 and the curved surface 44 define a part of the notch 41. Here, the term “parallel to each other” includes not only completely parallel to each other but also substantially parallel to each other.

  The outer surface of the latch 34 (the side surface of the latch 34 excluding the notch 41) is parallel to the rotation axis of the latch 34 (the axis of the through hole 39). The sandwiching surfaces 42 and 43 are inclined with respect to the rotation axis of the latch 34 as shown in FIG. Accordingly, the sandwiching surfaces 42 and 43 are inclined with respect to the outer surface of the latch 34. An R chamfered portion 45 that is R-processed is provided at the edge of the sandwiching surfaces 42 and 43.

  At this time, as shown in FIG. 3, the sandwiching surfaces 42 and 43 are parallel to the latched portion 32 in a state where the latch 34 sandwiches and latches the latched portion 32 of the striker 25. Inclined with respect to the rotation axis of the latch 34. The term “parallel to the locked portion 32” as used herein includes not only completely parallel to the locked portion 32 but also substantially parallel to the locked portion 32.

  The latch 34 has two entry surfaces 46 and 47 that are arranged so as to face each other on the opening side of the notch 41 with respect to the sandwiching surfaces 42 and 43. The entry surfaces 46 and 47 are formed so that the distance between the entry surfaces 46 and 47 gradually increases toward the opening side of the notch 41. The entry surfaces 46 and 47 define a part of the notch 41. By providing the entry surfaces 46 and 47 in the latch 34, the locked portion 32 of the striker 25 can easily enter the inside of the notch portion 41.

  The movement direction of the latch 34 when the slide door 6 is fully closed is inclined with respect to the extending direction of the locked portion 32 of the striker 25 as shown in FIG. When the sliding door 6 is fully closed, the latch 34 is brought into contact with the locked portion 32, so that the latch 34 is rotated with respect to the lock base 33 against the urging force of a spring (not shown). The latched portion 32 enters the notch 41 and the latch 34 sandwiches and latches the latched portion 32. As a result, the slide door 6 is locked with respect to the vehicle body 2 via the swing door 7.

  In the vehicle door structure 1 as described above, when the installation adjustment of the slide door 6 is performed, the mounting position of the guide body 18 with respect to the slide door 6 is adjusted in the front-rear direction of the vehicle body 2, About a direction, the attachment position of the striker 25 with respect to the swing door 7 is adjusted.

  FIG. 6 is a plan view (including a partial cross-section) schematically showing main parts of a conventional slide door fully-closed lock unit together with the slide door 6 and the swing door 7 as a comparative example. In FIG. 6, a conventional sliding door fully-closed lock unit 100 includes a striker 101 attached to the swing door 7, and a latch 103 attached to the slide door 6 and sandwiching and locking the locked portion 102 of the striker 101. have.

  An inclined surface 7 c that is inclined with respect to the front-rear direction and the left-right direction of the vehicle body 2 when the swing door 7 is fully closed is provided at the front end of the swing door 7. The striker 101 is attached to the inclined surface 7 c of the swing door 7. Therefore, the locked portion 102 of the striker 101 extends in a direction inclined with respect to the front-rear direction and the left-right direction of the vehicle body 2 when the swing door 7 is fully closed.

  7A is a plan view of the latch 103, FIG. 7B is a front view of the latch 103, and FIG. 7C is a cross-sectional view taken along the line 7c-7c in FIG. 7A. is there. In each drawing, the latch 103 is different from the above-described latch 34 only in the structure of the sandwiching surfaces 42 and 43. Similar to the outer surface of the latch 103, the sandwiching surfaces 42 and 43 are parallel to the rotation axis of the latch 103.

  The striker 101 is attached to the inclined surface 7c of the swing door 7 as described above. For this reason, the striker 101 is disposed obliquely with respect to the front-rear direction and the left-right direction of the vehicle body 2 when the swing door 7 is fully closed. At this time, the moving direction of the latch 103 when the sliding door 6 is fully closed is orthogonal to the extending direction of the locked portion 102 of the striker 101.

  The reason why the striker 101 is attached to the inclined surface 7c of the swing door 7 is as follows. That is, the rotation axis of the latch 103 is determined by the moving direction (opening / closing direction) of the slide door 6. The rotation axis of the latch 103 is a direction perpendicular to the moving direction of the slide door 6. When the latch 103 holds and locks the locked portion 102 of the striker 101, the striker 101 is parallel to the rotation axis of the latch 103 so that the latch 103 can be easily rotated. A locked portion 102 is disposed. Since the shape of the striker 101 is U-shaped, the surface to which the striker 101 is attached is an inclined surface 7 c so as to be perpendicular to the rotation axis of the latch 103.

  In such a conventional sliding door fully-closed lock unit 100, the striker 101 is disposed obliquely with respect to the front-rear direction and the left-right direction of the vehicle body 2 in the fully-closed state of the swing door 7. When the mounting position of 101 is adjusted, not only the position of the striker 101 along the left-right direction of the vehicle body 2 but also the position of the striker 101 along the front-rear direction of the vehicle body 2 changes. For this reason, it becomes difficult to perform the installation adjustment of the slide door 6.

  On the other hand, in the present embodiment, the sandwiching surfaces 42 and 43 of the latch 34 are arranged so as to face each other in parallel, and the latch 34 sandwiches and locks the locked portion 32 of the striker 25. Is inclined with respect to the rotation axis of the latch 34 so as to be parallel to the locked portion 32. For this reason, since the locked portion 32 of the striker 25 extends in a direction parallel to the front-rear direction of the vehicle body 2, the movement direction of the latch 34 when the slide door 6 is fully closed is determined. Even if it is inclined with respect to the extending direction, the latched portion 32 can be sandwiched and latched by the latch 34. Here, since the striker 25 is attached to the front end surface 7a of the swing door 7, when adjusting the attachment position of the striker 25, the position of the striker 25 along the front-rear direction of the vehicle body 2 is not changed. It is possible to adjust the position of the striker 25 along the left-right direction. Thereby, the installation adjustment of the slide door 6 can be performed easily.

  In addition, since the striker 25 is attached to the front end surface 7a of the swing door 7, the vehicle body 2 can be obtained by simply moving the striker 25 in the left-right direction of the vehicle body 2 without using a spacer for adjusting the attachment position. It is possible to easily adjust the position of the striker 25 along the left-right direction.

  In addition, since an R chamfered portion 45 is provided at the edge of the sandwiching surface 42.43 of the latch 34, when the latched portion 32 is sandwiched and locked by the latch 34, the sandwiching surface 42, It is prevented that the edge part 43 hits the to-be-latched part 32, and is damaged.

  The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the striker 25 is attached to the front end surface 7a of the swing door 7. However, the present invention is not limited to this configuration, and the striker 25 is disposed on the front outer side surface 7b of the swing door 7 as shown in FIG. It may be attached to.

  The striker main body 31 of the striker 25 has a locked portion 50 that extends in a direction parallel to the front-rear direction of the vehicle body 2. The latch 34 sandwiches and locks the locked portion 50. A spacer 51 is disposed between the front outer side surface 7 b of the swing door 7 and the base 30 of the striker 25. In such a configuration, the position of the striker 25 along the left-right direction of the vehicle body 2 is adjusted by adjusting the thickness of the spacer 51.

  Moreover, although the vehicle door structure 1 of the said embodiment is provided with the sliding door 6 and the swing door 7, this invention does not have a swing door and for vehicles which slide so that a sliding door can be opened and closed with respect to a vehicle body. It can also be applied to door structures. In this case, the sliding door fully-closed lock unit directly locks the sliding door with respect to the vehicle body. At this time, the striker 25 is attached to a surface perpendicular to the front-rear direction or the left-right direction of the vehicle body.

  Furthermore, although the vehicle door structure 1 of the above embodiment is applied to the side portion of the vehicle body 2, the present invention is also applicable to the rear portion of the vehicle body 2.
