There are those shown in the above publication and those shown in FIGS. 5 to 7. In the figure, 1 is a striker, which is attached to a mounting position of the vehicle body panel 3 facing the opening/closing side end surface 2a of the door 2 in order to engage/disengage with a locking device (not shown) provided on the opening/closing side end surface 2a of the door 2. It is. This striker 1
consists of a locking part 1a and a base 1b, and its two legs are fixed to the base 1b so that the locking part 1a, which is generally U-shaped, projects horizontally in the direction of the door 2 (direction A in the figure). are doing. Furthermore, two bolt insertion holes 1c for mounting are provided at predetermined positions on the base 1b, one above the other. Two bolt insertion holes 3a that are larger than the diameter of the bolt 4 (larger than the bolt insertion hole 1c of the base 1b) are provided at the mounting position of the vehicle body panel 3 in correspondence with the bolt insertion hole 1c. . Further, 5 is a retainer member, which is attached to the back surface of the vehicle body panel 3 to position and hold a tap plate 6, which will be described later. This retainer member 5 has a tray shape consisting of a bottom plate 5a and a vertical wall 5b, and the bottom plate 5a has a bolt insertion hole larger than the diameter of the bolt 4, similar to the bolt insertion hole 3a provided in the vehicle body panel 3 described above. Two holes 5c are provided. Further, vertical walls 5b are provided on three sides of the bottom plate 5a so as to enclose the tap plate 6,
Its height is approximately the same as the thickness of the tap plate 6. This vertical wall 5b is provided with a pair of upper and lower claw portions 8 that are opposed to each other, and a protrusion 8a that projects toward the vehicle body panel 3 is provided at the tip of each of these claw portions 8. This retainer member 5 is fixed to the back surface of the vehicle body panel 3 in such a manner that the bolt insertion hole 5c matches the bolt insertion hole 3a of the vehicle body panel 3. Tap holes 6a are formed in the tap plate 6 at the same intervals as the bolt insertion holes 1c of the striker 1. Further, near both ends of the tap plate 6, there are recesses 6 with which the protrusions 8a of the claws 8 engage.
b is provided. The tap plate 6 is connected to this recess 6.
The protrusion 8a of the claw portion 8 is engaged with the protrusion 8a of the claw portion 8, and the retainer member 5 is positioned and held on the rear surface of the vehicle body panel 3 (side B in the figure). Therefore, the striker 1 moves from the bolt insertion hole 1c of the base 1b to the bolt insertion hole 3a.
, 5c, and fasten them to the tap holes 6a of the tap plate 6, thereby attaching them to the vehicle body panel 3.

0003

[Problem to be Solved by the Invention] In such a conventional technique, since the tap plate 6 is accurately attached to a predetermined position in advance, the striker 1 can be reliably attached to the predetermined position by the tap plate 6. be able to. However, once the striker 1 is installed, it may be necessary to adjust the installation position in order to adjust for errors caused by the installation of the door 2, etc. In such a case,
Bolt insertion holes 3a in the vehicle body panel 3 and retainer member 5,
5c is made large to ensure an adjustment allowance, but since the tap plate 6 is fixed to the retainer member 5 attached to the vehicle body panel 3, it is necessary to release the fixation of the tap plate 6. For example, after loosening the bolts 4, the striker 1 is struck with a hammer or the like to release the tap plate 6 from the convex-concave engagement state with the claw portion 8. At this time, there is a risk that the striker 1 may damage the painted surface of the vehicle body panel 3. In addition, in order to avoid such a situation, it is possible to make the tap plate 6 movable without fixing it in advance so that the mounting position of the striker 1 can be adjusted. Since the position of the striker 6 is not determined, there is a possibility that the exact mounting position of the striker 1 cannot be determined.

[0004] The present invention was made by paying attention to such conventional technology. Under normal conditions, the tap plate can be fixed at the regular position, and if adjustment is necessary, simply loosen the bolt. The present invention provides a striker mounting structure for an automobile door lock device whose position can be adjusted.

[0005]

[Means for Solving the Problems] In order to achieve the above object, a striker mounting structure for an automobile door lock device according to the present invention is provided by attaching a tap plate to a retainer member with a tap plate raised from a vehicle body panel by a predetermined distance. A deformable support part is provided for engaging the part and the concavity and convexity.

[0006]

[Function] According to the striker mounting structure of the automobile door lock device according to the present invention, when the tap plate is lifted up a predetermined distance from the retainer member provided on the back surface of the vehicle body panel, the tap plate is engaged with the claw portion of the retainer member. A support section was provided to allow the Therefore, before the striker is attached to the vehicle body panel, the tap plate is suspended at the proper position of the retainer member by the support part and the claw part, making it possible to ensure an accurate mounting position. . Further, since the support part is deformable, when the bolt is tightened when the striker is attached, the tap plate is drawn toward the vehicle body panel and the support part is deformed. As a result, the tap plate is released from the convex-concave engagement with the claw portion, so that in the unlikely event that the mounting position of the striker needs to be adjusted, the adjustment movement can be made by loosening the bolt again.

[0007]

[Embodiment] A preferred embodiment of the present invention will be described below with reference to FIGS. 1 to 4.
The explanation will be based on. Incidentally, parts common to those of the conventional example are given the same reference numerals, and redundant explanations will be omitted. 20 is a retainer member, which includes a substantially rectangular bottom wall 20a;
It consists of vertical walls 20b provided on three sides around a. This bottom wall 20a is provided with bolt insertion holes 20c that correspond to the two bolt insertion holes 1c provided in the base 1b of the striker 1 and are larger than the bolt insertion holes 1c. A pair of claws 21 facing each other is provided on the vertical wall 20b, and a protrusion 21a facing toward the vehicle body panel 3 side (A side in the figure) is formed at the tip end thereof. Further, on the bottom wall 20a, there is provided a direction corresponding to the claw portion 21 and toward the claw portion 21 (in the opposite direction to the vehicle body panel 3).
A support portion 22 is formed which is cut and raised, and lifts up the tap plate 23. In this way, since the tap plate 23 is sandwiched between the support part 22 and the claw part 21, the height of the vertical wall 20b is determined by the height of the tap plate 23.
It is higher than the conventional example by the amount that has been lifted. Further, recesses 23a are formed near both ends of the tap plate 23 to engage with the convex portions 21a of the claw portion 21, and the tap plate 23 is lifted up by the support portion 22 and pressed against the claw portion 21, so that the tap plate 23 is It is held in the normal position by being engaged with the portion 21 (see FIG. 1).

Next, the mounting operation of the striker 1 will be explained. The retainer member 20 includes two parts provided on the bottom wall 20a.
It is firmly fixed in advance to the back surface of the vehicle body panel 3 with the two bolt insertion holes 20c aligned with the two bolt insertion holes 3a of the vehicle body panel 3. Then, the bolt 24 is inserted so that the bolt insertion hole 1c of the base 1b of the striker 1 is aligned with the bolt insertion hole 3a of the vehicle body panel 3. This bolt 24 is threaded into the tap hole 23b of the tap plate 23 through the bolt insertion holes 3a, 20c of the vehicle body panel 3 and the retainer member 20 (the state shown in FIG. 1). and,
When the bolts 24 are tightened, the tap plate 23 is gradually drawn toward the vehicle body panel 3 while deforming the support portion 22 of the retainer member 20, and the concave portion 2 of the tap plate 23 is
3a and the convex portion 21a of the claw portion 21 is released (state shown in FIG. 2). When the bolt 24 is further tightened completely, the striker 1 is firmly attached to a predetermined position on the vehicle body panel 3 (the state shown in FIG. 3). After mounting in this manner, if it becomes necessary to adjust the mounting position of the striker 1, loosen the bolt 24 again. Once the bolts 24 are tightened, the support portion 22 is deformed and stored in the notch in the bottom wall 20a of the retainer 20 and becomes flat (the state shown in FIG. 3), and the tap plate 23 can be moved by simply loosening the bolts 24. It becomes possible. On the other hand, bolt insertion holes 3a and 2 of the vehicle body panel 3 and the retainer member 20
Since 0c is larger than the diameter of the bolt 24, the mounting position of the striker 1 can be adjusted within this range.

According to such a striker mounting structure of an automobile door lock device, the claw portion 21 of the retainer member 20
The support part 22 that lifts the tap plate 23 facing the
Because of this provision, the tap plate 23 is locked in a lifted state between the claw portion 21 and the support portion 22 before the striker 1 is attached. For this reason, the tap plate 23 can be provided at a regular mounting position, and the mounting position of the striker 1 can also be accurate. Furthermore, the coating liquid can easily circulate in the gap between the tap plate 23 and the vehicle body panel 3, improving the coating quality. Even if it becomes necessary to adjust the mounting position of the striker 1, once the bolt 24 is tightened, the support portion 22 will be deformed and become flat, and even if the bolt 24 is loosened afterwards, the tap plate 23 will remain unchanged. Since it is released from the concave-convex locking state with the claw portion 21, it is in a movable state, and the position of the striker 1 can be easily adjusted.

0010

[Effects of the Invention] As explained above, in the striker mounting structure of the automobile door lock device according to the present invention, the tap plate is engaged between the support portion and the claw portion in a state where the tap plate is raised from the retainer member. When installing, the striker is installed in the normal installation position. In addition, once the bolt is tightened, the deformable support part deforms and becomes flat, so even if you need to adjust the mounting position of the striker, you can easily move the tap plate by loosening the bolt slightly. The mounting position can be adjusted.
