As this kind of fuel lid opener, there is one described in the specification and drawings of Japanese Patent Application No. 8-209811, which is a double cab type small size as shown in FIGS. The base plate 18 is fixed to an inner plate 30 arranged substantially parallel to a back panel 29 of a vehicle such as a truck. The inner plate 30 of the base plate 18 is fixed to the inner plate 30.
Is fixed to the inner plate 30 by inserting a tightening member 32 such as a bolt or a tapping screw into the tightening hole 31 of the base plate 18 and tightening the inner plate 30.

The base plate 18 has a shaft 19 extending in a direction substantially orthogonal to the base plate 18.
Is rotatably pivotally mounted, and a bell crank 21 which is biased in a required direction (clockwise direction in FIG. 9 ) by a spring 20 is fitted to the shaft 19 so as to be arranged on one side of the base plate 18. And an engaging pin 2 as an engaging portion that extends substantially parallel to the shaft 19 at its tip.
A cable holding portion 24 is provided with a lever 23 protruding from the base plate 18 and fitted to the other side of the base plate 18, and a lever 23 that is interlocked with the rotation of the bell crank 21. The end portion of the outer cable 25 is fixed to the outer cable 25, and the end portion of the cable 26 slidably inserted into the outer cable 25 and connected to the operating lever for the fuel lid opener 1 (not shown) in the driver's seat is attached. The engagement pin 22 of the lever 23 is connected to the hook 28 which is the engaged portion attached to the fuel lid 2 side by being connected to the tip end portion of the bell crank 21 via the engaging portion 27, as shown in FIGS. It is adapted to engage as shown.

In the fuel lid opener 1 as shown in FIGS. 7 to 10, when the operating lever for the fuel lid opener 1 (not shown) in the driver's seat is pulled and the cable 26 is pulled, the bell crank 21 causes the spring 20 to urge the spring 20. 9 counterclockwise in FIG. 9 , and the lever 23 rotates integrally with the bell crank 21 in the same direction.
The engaging pin 22 protruding from the tip of the lever 23 is disengaged from the hook 28, and the fuel lid 2 is opened by the urging force of a spring or the like (not shown), while the fuel lid 2 is opened. When the fuel lid 2 is closed, the hook inclined portion 28a comes into contact with the engaging pin 22, and the lever 23 is rotated against the biasing force of the spring 20, so that the engaging pin 22 is engaged with the hook 28 again. And the fuel lid 2 is kept closed.

[0006]

By the way, in the case of the fuel lid opener 1 as described above, the inner plate 3 is used.
When the assembly of the base plate 18 with respect to 0 shifts as shown by the phantom line in FIG. 7 due to stacking of dimensional tolerances of individual parts, etc., the fuel lid 2 protrudes from the outer surface of the body accordingly, and it looks good. It will get worse.

Therefore, as some adjustment structure, the tightening hole 31 of the base plate 18 is enlarged to make an adjustment allowance. However, the tightening hole 31 of the base plate 18 is simply made larger to make the adjustment allowance. If it is made, it takes time and effort to assemble the base plate 18 to the regular position with respect to the inner plate 30, and there is a possibility that it may have an adverse effect.

In view of the above situation, the present invention allows a tightening member to be inserted into a tightening hole of a resin component to perform tightening without special position adjustment during normal assembly. On the other hand, the adjustment allowance can be secured in the tightening hole only when the assembled resin parts are misaligned and adjustment is required, and the resin parts can be properly tightened and fixed at the desired position. It is intended to provide an attached structure.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show an example of an embodiment for carrying out the present invention. In the drawings, the parts denoted by the same reference numerals as those in FIGS. 7 to 10 represent the same things, and the basic structure is 7 to 1
0 is similar to the conventional one shown in FIG. 0 , but the feature of this illustrated example is that, as shown in FIGS. 1 to 3, the inner diameter of the tightening hole 31 of the base plate 18 as a resin component is set to the tightening member 32. Of the base plate 18
So that a thin portion 33 is formed on the periphery of the tightening hole 31 of
The point is that the recess 34 is formed in the base plate 18.

In the illustrated example, the recess 34 is in the shape of an elongated hole extending in the direction in which adjustment is considered necessary.

Next, the operation of the illustrated example will be described.

When the base plate 18 is fixed to the inner plate 30 (see FIG. 7 ) as an assembly part, as shown in FIG. 2, the tightening member 32 is inserted into the tightening hole 31 of the base plate 18 and tightened. If you do, you don't have to do any special adjustment.

On the other hand, when the assembled base plate 18 is misaligned and needs to be adjusted, for example, as shown in FIG. Is removed, the tightening hole 31 is expanded in a desired direction, an adjustment allowance is secured in the tightening hole 31, and the displacement of the base plate 18 can be corrected.

In this way, in the normal assembly, the tightening member 32 can be inserted into the tightening hole 31 of the base plate 18 to perform the tightening without any special position adjustment, while the assembly is performed. The adjustment allowance can be secured in the tightening hole 31 only when the base plate 18 is displaced and needs to be adjusted, and the base plate 18 can be appropriately tightened and fixed at a desired position.

FIG. 4 and FIG. 5 show the adjustment margin on the surface of the thin portion 33 formed at the periphery of the tightening hole 31 of the base plate 18 in the example shown in FIGS. A mark 35 serving as a guide is attached.

[0031]

Incidentally, the tightening structure for the resin component of the present invention is not limited to the above-mentioned illustrated example, and when the base plate 18 is originally thin, the recess 34 is intentionally used.
It is also possible to form a mark as a guide for taking an adjustment allowance on the peripheral surface of the tightening hole 31 of the base plate 18 without forming the mark, and as the mark 35, a concave portion such as a marking line is formed. Is also the same as the protrusion, and can be applied to resin parts other than the base plate 18 of the fuel lid opener 1, and other changes can be made without departing from the scope of the invention. Of course.

[0033]

As described above, according to the tightening structure of the resin part of the present invention, the tightening is performed with respect to the tightening hole of the resin part without special position adjustment during the normal assembly. While it can be tightened by inserting the attached member,
Only when the assembled resin parts are misaligned and adjustment is required, locate the tightening holes using the marks as a guide according to the amount of misalignment.
By expanding in the desired direction , the adjustment allowance can be secured in the tightening hole, and the excellent effect that the resin component can be accurately tightened and fixed at the desired position can be obtained.
