Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the structure of a fuel inlet portion of an automobile or the like, and particularly to one in which a locking mechanism for the fuel lid is suitably provided.

[Prior Art] A fuel inlet of an automobile or the like is generally arranged in a quarter panel 1 forming a rear side wall of a vehicle body, as shown in FIG. As shown in FIG. 4, this fuel inlet portion A has a fuel inlet 5 disposed within a substantially rectangular recess 3 formed by projecting a part of the quarter panel 1 inward into the vehicle body. It has a structure. In a resin fuel inlet in which the fuel inlet 5 is formed from a resin shield member, a locking mechanism of the fuel lid is constructed as shown in FIG. That is, a fuel inlet 5 consisting of two layers, a first shield member 5a and a second shield member 5b, is attached to a through hole 3b formed in the bottom 3a of the recess 3. On the side wall of the fuel inlet 5 inside the vehicle body, an L-shaped bracket 9 is welded to the back surface of the bottom portion 3a via a plate 11. Bolt holes 9a are formed in this bracket 9, and a lock retainer 13 having the shape shown in FIG.
It is screwed to the bracket 9 by. A locking pawl 13a formed on the surface of the vehicle body of this retainer 13 engages with a key cylinder 21 attached to the fuel lid 19, so that the fuel lid 19 is locked.

In the fuel lid locking mechanism constructed in this way, the locking retainer 13 is fastened by one bolt 15. Therefore, as shown in FIG. 7, an inner 23 is attached to the fuel lid 19 instead of the key cylinder 21, and on the other hand,
By attaching the opener mechanism 25 to the bracket 9 and inserting the engaging claw 25a of the opener mechanism 25 that engages the engaging groove 23a of the inner 23 into the hole of the bolt 15, a fuel lid locking mechanism that does not use a key cylinder can be realized. It has the advantage of being easy to configure.

[Problem to be solved by the invention] However, as described above, in the lock mechanism in which the lock retainer is screwed by one bolt, it is difficult to accurately position the lock retainer 13 around the bolt axis. Difficult to decide. When the retainer is out of position, the locking claw 13a of the retainer and the key cylinder 21
When the fuel lid 1
The surface of the panel 9 does not match the surface of the surrounding quarter panel 1, resulting in poor installation accuracy and a poor appearance. Furthermore, if the retainer is misaligned to a large extent, there is a risk that the fuel lid will not be locked.

The purpose of this invention is to solve these problems and
To provide a fuel inlet structure capable of accurately positioning a lock retainer in a lock mechanism in which the lock retainer is screwed by one bolt.

[Means for Solving the Problems] The present invention includes forming a recess by protruding a part of the surface of the vehicle body into the vehicle body, and forming a recess from the bottom of the recess around a through hole formed at the bottom of the recess. A fuel inlet is formed by disposing a shield member to cover the inner periphery of the through hole, and the mounting portion is fixed to the bottom of the recess and extends toward the inner periphery of the through hole along the shield member. A fuel inlet structure in which a locking retainer having a latch claw capable of locking the fuel lid that can open and close the recess is screwed to the mounting portion of the bracket, wherein the locking retainer has a surface side of the vehicle body. A flange is formed at the outer end facing the shield member, the flange being bent and extending along the surface of the shield member to press and hold the outer peripheral edge of the shield member to the bottom of the recess and to prevent the lock retainer from rotating. It is a feature.

[Function] In the fuel inlet structure of the present invention, the flange of the lock retainer can prevent rotation around the bolt axis when the lock retainer is screwed with bolts, and the lock retainer can be positioned accurately. can do. Furthermore, the outer peripheral edge of the shield member can be pressed and held against the bottom of the recess by the flange of the locking retainer, so that the shield member can be securely attached and the sealing performance can be improved.

[Example] Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2.

The structure of the fuel inlet section in this example is almost the same as the structure of the fuel inlet section shown in FIGS. The explanation will focus on the structure of the locking retainer, which is the subject of the invention.

First, FIG. 1 is a perspective view showing the installed state of the locking retainer 31 of this example, and FIG. 2 is a sectional view showing a portion taken along the - line. As shown in the figure, the locking retainer 31 is formed from a flat plate member, and a locking pawl 31b bent at a right angle is formed at an upper end 31a facing upward of the vehicle body. The tip of this latch claw 31b can engage with the latch plate 21a of the key cylinder 21 attached to the fuel lid 19 side.
1b and the key cylinder 21 constitute a locking mechanism for the fuel lid 19. On the other hand, at the outer end of the locking retainer 31 facing the vehicle body surface side, a rotation preventing flange 31c is formed which is bent at right angles along the surface of the first shield member 5a. Lock retainer 31 configured in this way
is fastened by a bolt 15 to a bracket 9 disposed on the back side of the second shield member 5b.

Here, when attaching the locking retainer 31 with the bolts 15, since the rotation preventing flange 31c is in contact with the portion 5c of the first shield member 5a facing the vehicle body surface side, the bolt 1 is attached.
The position of the retainer in the direction around the axis 5 is always fixed at a fixed position. Therefore, the locking retainer 31 is screwed to the fuel inlet side wall without displacement. Furthermore, this flange 31c functions not only to prevent the retainer from rotating, but also as a pressing member that presses the shield members 5a, 5b against the bottom portion 3a. Therefore, there is an advantage that the sealing performance between the shield member 5b and the bottom portion 3a is improved, and the intrusion of rainwater or the like from this area can be reliably prevented. Further, in this example, since the flange 31c is formed to have a wide width covering the entire width of the outer end of the retainer, the sealing performance is further improved.

[Effect of the invention] As is clear from the above explanation, in the fuel inlet structure of the invention, the outer peripheral edge of the shield member is recessed in the locking retainer screwed to the inner peripheral wall of the fuel inlet. Since we have formed a flange that presses and holds the lock retainer at the bottom of the engine and prevents it from rotating, it is possible to install the lock retainer without positional displacement, and this will prevent the fuel lid and quarter panel from shifting due to such positional displacement. This has the excellent effect of not causing problems such as poor installation, and improving the sealing performance between the shield member and the bottom.
