Next, the fixing structure of the fuel lid lock device 18 of the present embodiment will be described in detail.

As shown in FIG. 2, the fuel lid lock device 18 includes a cylindrical retainer 26 and a cylindrical lock 28 that can be inserted into the retainer 26. A ring-shaped flange 30 is formed on an outer peripheral portion near one end 26A of the retainer 26. A pair of wings 32 are formed at an outer peripheral portion between the end 26 </ b> A and the flange 30 at 180 ° positions along the outer peripheral direction. , The retainer 26 can be easily rotated.

The other end (insertion end) 26 of the retainer 26
B and the flange portion 30 are formed as an insertion portion 31, and the insertion portion 31 is provided with a mounting hole 15 formed in the bracket 13.
Can be penetrated through a shield hole 17A formed in a seal member 17 made of a rubber sheet. Also, the insertion part 3
In FIG. 1, a pair of L-shaped slits 36 are formed at 180 ° positions along the outer peripheral direction. That is,
The slit 36 is provided with an insertion portion 36A along the insertion direction of the retainer 26 (the direction of the arrow C in FIG. 2) and an engagement portion formed at an end of the insertion portion 36A on the flange 30 side along the outer peripheral direction of the retainer 26. And a joint 36B.

At the outer periphery of the retainer 26, a slit 36 is provided.
A pair of thickened projections 38 are formed along the insertion portion 36A.
Are formed at 180 ° positions along the outer peripheral direction, and these projections 38 are formed with a pair of cutouts 17B formed on the outer peripheral portion of the shield hole 17A of the sealing material 17 and the mounting hole 15 of the bracket 13. Can pass through a pair of cutouts 15A formed in the outer peripheral portion of. A thin portion 40 is formed at an end of the protruding portion 38 on the flange 30 side along the outer peripheral portion of the retainer 26 toward the opposite side to the engaging portion 36B. The thin portion 40 is formed to be approximately half the width of the protrusion 38. When the retainer 26 is rotated in the temporary fixing direction (the direction of arrow D in FIG. 2), the edge 13A of the notch 15A of the bracket 13 is thinned. Engage the part 40.

The wall portion 40A of the thin portion 40 which faces the flange portion 30 has an inclined surface.
When rotated in the direction of arrow D, the flange 30 and the bracket 13
The seal member 17 sandwiched between the brackets 13 is compressed, and the reaction force prevents the retainer 26 from easily coming off the bracket 13.

A lock claw 42 is formed near the root of the engaging portion 36B of the slit 36. This lock claw 4
Numeral 2 protrudes from the wall of the engaging portion 36B facing the flange 30. The wall of the lock claw 42 following the insertion portion 36A is a tapered portion 4 inclined in a direction to reduce the width of the engaging portion 36B.
It is set to 4.

The lock 28 has a cylindrical shape that is longer than the retainer 26 and has a small-diameter portion 28 formed at one end.
The tip of A protrudes from the end 26A of the retainer 26. The other end is a large-diameter portion 28B, and a pair of wing portions 46 are formed on the outer peripheral portion of the large-diameter portion 28B at 180 ° positions along the outer peripheral direction, respectively.
The lock 28 can be easily rotated by putting a thumb and an index finger on the pair of wings 46.

A pair of projections 48 are formed on the outer peripheral portion of the intermediate portion 28C in the longitudinal direction of the lock 28 at 180 ° positions along the outer peripheral direction. These projections 48 have a U-shape as viewed from the radial direction, and have
The slit 50 is formed from the large diameter portion 28B side. The protrusion 48 is formed with a tapered portion 48A that slides with the tapered portion 44 of the retainer 26.
Is rotated in the locking direction (the direction of arrow E in FIG. 2), the tapered portion 48A slides on the tapered portion 44 of the retainer 26, and the retainer 26 is pulled in the direction of arrow C.
0 and the sealing material 17 sandwiched between the wall portion 40A are compressed,
Further, when the lock 28 is rotated in the lock direction, the protrusion 4
8 engages with the lock claw 42 of the retainer 26.

As shown in FIG. 1, a latch base 60 is fixed inside the lock 28, and a latch body 61 is inserted into the latch base 60 so as to be movable in the axial direction. . The latch body 61 is urged by a coil spring 62 in the locking direction (the direction of arrow F in FIG. 1).
Of the lock plate 22 is engaged with the engagement hole 24 of the lock plate 22.
A cable 64 is connected to the latch main body 61. When the cable 64 is pulled in an unlocking direction (the direction of arrow G in FIG. 1) by an operation lever (not shown) provided in the vehicle, the latch main body 61 becomes a coil. It moves in the direction of arrow G against the urging force of the spring 62, and the engagement between the distal end portion 61A of the latch body 61 and the engagement hole 24 of the lock plate 22 is released.

Next, the operation of the present embodiment will be described. In the fuel lid lock fixing structure of the present embodiment, the fuel lid lock device 18 is connected to the bracket 13.
When mounting the retainer 26, the insertion portion 31 of the retainer 26 is inserted into the mounting hole 15 of the bracket 13 from the fuel opening side.
The notch 17B formed on the outer peripheral portion of the shield hole 17A of the sealing material 17 and the mounting hole 1 of the bracket 13
5 is inserted into the shield hole 17A and the mounting hole 15 in accordance with the notch 15A formed on the outer peripheral portion of the bracket 5, and rotated in the direction of arrow D in FIG. 2 to temporarily fix the edge 13A of the mounting hole 15 of the bracket 13. Is engaged with the thin portion 40.

At this time, the wall portion 40A facing the flange portion 30 of the thin portion 40 has an inclined surface, and when the retainer 26 is rotated in the direction of arrow D in FIG. 2, the flange portion 30 and the wall portion 40A are separated. The sandwiched sealing material 17 is compressed, and the retainer 26 is temporarily fixed in a state where it cannot be easily removed from the mounting hole 15.

Next, the lock 28 is inserted into the retainer 26 from the side of the bracket 13 opposite to the fuel opening. At this time, the protrusion 28 of the lock 28 is inserted into the insertion portion 3 of the slit 36.
6A until it abuts against the bottom, and after abutment, lock 28
Is rotated in the direction of arrow E in FIG. Thereby, the protrusion 5
The tapered portion 48A of the retainer 26 is
To pull the retainer 26 in the direction of arrow C, and the seal member 17 sandwiched between the flange portion 30 and the bracket 13 is compressed. Further, when the lock 28 is rotated in the direction of arrow E in FIG. 2, the projection 48 is engaged with the lock claw 42 of the retainer 26, and the lock 28 can be fixed to the retainer 26 and the bracket 13. Therefore, it is not necessary to work from both sides of the bracket 13 at the same time, and the assembling workability is improved.

In this embodiment, the projections 4 of the lock 28 are provided.
8 is engaged with the slit 36 of the retainer 26, the sealing material 1 sandwiched between the flange portion 30 and the bracket 13.
Since 7 is compressed, the sealing performance can be improved.

Incidentally, as shown in FIG.
The contact surface 30 of the flange portion 30 of the retainer 26 with the sealing material 17
A can be adjusted by changing the dimension H in the assembled state of A and the projection 48 of the lock 28 (the state of FIG. 1).

In the present invention, an example in which the seal member 17 is made of a rubber sheet has been described. However, when the seal member is made of a member harder than rubber such as resin, the flange portion 30 of the retainer 26 and the seal member 17 are connected to each other. Sealing properties can be improved by sandwiching a rubber packing or the like between the two.
