Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is an automobile provided with an opening in a body panel at a cap position of a fuel tank, one end of which is hinged, and the other is provided with a lock catch that can be unlocked by a key and locked by a lock claw. The present invention relates to a fuel tank lid.

[0002]

[Prior art]

 FIG. 4 shows a lid structure of this kind. One end of the quarter panel 1 is urged by a leaf spring 2 in the opening direction and pivotally supported by a hinge 3 in the opening 1a of the quarter panel 1. A lid 8 is provided at the end of the lid, and a lock catch 7 that engages with the lock claw 5 is provided below. The lock catch 7 includes a hanging portion 7a, an inclined surface 7b at the tip of the hanging portion, which abuts against the tip edge of the lock claw 5 when the lid 8 is closed, and the abutment causes the lock claw 5 to retreat and engage with the back surface thereof. It is formed as a catch pawl with a mating engagement surface 7c. The lock pawl 5 is unlocked by the engine key, and the cap of the fuel tank is located below the seal portion 6 in the figure.

However, in this case, there is a problem in that a building step S is generated between the quarter panel 1 and the lid 8 due to the stacking of dimensions and mounting accuracy of the hinge 3, the lock catch 7, the lock claw 5, and the like. On the other hand, in Japanese Patent Laid-Open No. 63-188522, a method is provided in which a hinge arm of the lid is provided with an adjusting device for setting the lid installation position by adjusting the position of the conical expanding member in the direction along the lid. Is taught.

[0004]

[Problems to be solved by the device]

 However, this adjusting device is structurally complicated and cannot be easily adopted in the lid structure shown in FIG.

It is therefore an object of the present invention to provide a lid for a vehicle fuel tank of the kind mentioned at the outset in which lid installation errors can be adjusted with a simple additional structure.

[0006]

[Means for Solving the Problems]

 In order to achieve this object, the present invention provides, according to claim 1, spring-biased in an opening direction at an opening of a body panel at a cap position of a fuel tank, and one end of the hinge is hinged. In a fuel tank lid for an automobile, on the other end of which a lock catch that engages with a lock claw that is unlocked by a key is projected, the lock catch is fixed to the back surface of the lid and A circular base with a threaded cross section, a cylindrical part with a screw thread formed on the inner peripheral surface and a threaded part that is screwed into the thread, and is located closer to the tip than the cylindrical part, and the closing direction of the locking claw when closed. It is composed of a lock catch body that is integrally formed with a ring-shaped catch claw that abuts from and engages with, and is located closer to the base end than the base thread and larger than this thread surface. Diameter base With teeth on the peripheral surface is formed in a ring shape, the position of the base end nearer the threads of the cylindrical portion, wherein the engaging piece for engaging the teeth are formed.

According to the second aspect, the relationship between the male thread and the female thread of the first aspect can be reversed.

[0008]

[Action]

 When screwing the lock catch body into the base fixed to the lid, the rotation position of the lock catch body adjusts the height of the catch claw with respect to the lid. Each time the adjustment is performed, the lid is closed and the step with the surrounding body panel is checked, and the rotational position of the lock catch main body that is in the same plane is the final rotational adjustment position. The rotation adjustment position is secured by the engagement of the engagement piece with the tooth profile.

[0009]

【Example】

 1 and 2 show an embodiment in which the present invention is applied to a lid having the structure shown in FIG. 4 and a lock mechanism thereof, and the same or equivalent parts will be described with the same reference numerals. In FIG. 1, a lock catch 9, which is provided on the rear surface of the tip portion of the lid 8 (relatively small), has a cylindrical base portion 10 with threads 11 formed on the outer peripheral surface and a screw thread on the inner peripheral surface. A cylindrical portion 22 formed with a thread 23 to be screwed with 11 and a ring-shaped catch pawl 21 which is located closer to the tip than the cylindrical portion and abuts and engages with the lock pawl 5 from the closing direction when closed. The lock catch body 20 is formed in the. A ring-shaped groove 25 into which the lock claw 5 engaged with the catch claw 21 is inserted is formed between the catch claw 21 and the cylindrical portion 22 which are in the shape of an inverted truncated cone.

The outer peripheral surface of the base, which is located closer to the base end than the thread 11 of the base 10 and has a diameter larger than the thread surface, has a vertical width larger than an assumed error dimension, and The tooth profile 12 having a pitch in consideration of setting accuracy is formed in a ring shape. A weight reducing hole is formed in the inner plate 8a attached to the back surface of the lid 8 by hemming the periphery, and a weld bolt 19 is welded to the seat 19a. A screw through hole 13 into which the weld bolt is inserted is formed on the upper surface of the base portion 10. Further, the seat 19a is formed with an engagement hole 15a into which the anti-rotation claw 15 formed on the upper surface of the base 10 is engaged.

The recessed portion of the tooth profile 12 is engaged with a cylindrical portion 22 a of the lock catch body 20 which is closer to the base end than the screw thread 23 of the cylindrical portion 22 and has an inner peripheral surface having a diameter larger than this screw thread surface. As described above, the engaging pieces 24 having bending elasticity in the radial direction are formed by the slits 24a on both sides.

The operation of the vehicle fuel tank lid thus configured is as follows. When attaching the lid 8 to the opening 1a, as shown in FIG. 4, one end of the lid 8 is hinged by the hinge 3 and the leaf spring 2 is assembled and biased in the opening direction. Then, as shown in FIG. 2, the weld bolt 19 is inserted into the screw through hole 13 of the base portion 10 and screwed by the nut 19b. Next, the lock catch main body 20 is screwed into the base portion 10 and is engaged with the recess 12a of the tooth profile 12 of the protrusion 24b of the engaging piece 24 to lock the rotational position (unlocked in FIG. 3A and locked in FIG. 3B). (A closed state is shown), and the height position of the catch claw 21 with respect to the lid 8 is adjusted. With this, the lid 8 is closed, and the step between the lid 8 and the quarter panel 1 is confirmed with the catch pawl 21 engaged with the lock pawl 5. Then, the lock catch main body 20 is set at the rotational position where the step is minimized, and the lock catch main body 20 is locked by the tooth profile 12 and the engaging piece 24, and the adjustment work is completed.

It should be noted that, instead of the above-described embodiment, a cylindrical base portion having a screw thread formed on the inner peripheral surface and a cylinder having a screw thread formed on the outer peripheral surface so as to reverse the relationship between the male screw and the female screw, or Alternatively, the lock catch main body may have a circular cross-section, which is a cylinder, and a ring-shaped catch claw that is engaged with the lock claw 5 near the tip thereof. Then, a tooth profile is formed in a ring shape on the inner peripheral surface of the base that is closer to the base end than the thread of the base and has a diameter smaller than that of the thread, and the tooth profile is formed on the lock catch body closer to the base than the thread. Forming an engaging piece for engaging with.

[0014]

[Effect of device]

 As described above, according to the present invention, the fuel lid installation error that may occur due to the stacking of each component can be absorbed by the simple rotation adjustment of the lock catch, and therefore the installation quality can be improved with a simple structure. Planned. It is possible to set with high accuracy according to the pitch of the tooth profile by continuous rotation adjustment.
