On the other hand, in the key lock cylinder 8 arranged on the outer panel 13 together with the garnish 9, the inner cylinder 20 is inserted and arranged in the through hole 22, and the mounting hole 18 a is arranged corresponding to the engaging hole 23. At this time, even if there is a deviation between the inner cylinder 20 and the through hole 22, and the mounting hole 18a and the engagement hole 23,
Since the through hole 22 and the engagement hole 23 are formed large in advance,
This shift is absorbed by the through hole 22 and the engaging hole 23. And
When the screw 19 is screwed into the screw hole 36 of the stud 35 through the through hole 22 and the engaging hole 23, the key lock cylinder 8 can be further fixed to the outer panel 13 while being positioned in the tubular portion 25. . Further, when the release lever 25 is attached thereafter, the attachment of the key lock cylinder 8 and the garnish 9 to the back panel 13 is completed.

Therefore, according to the mounting structure of the key lock cylinder according to this embodiment, before the key lock cylinder 8 and the garnish 9 are mounted on the trunk lid 4, the clip
Insert the 16 into the tubular part 25 of the garnish 9 and attach it,
After that, the key lock cylinder 8 is press-fitted into the clip 16 and temporarily fixed in a state where it is positioned with respect to the tubular portion 25, and in this state, the key lock cylinder 8 and the garnish 9 are attached to the outer panel 13 on the front side of the trunk lid. be able to. Further, at this time, the deviation caused by the manufacturing error or the like between the key lock cylinder 8 side and the outer panel 13 side can be absorbed by forming the through hole 22 and the engagement hole 23 provided on the outer panel 13 side to be large. Therefore, with the key hole 8a and the through hole 24 aligned,
As it is, the key lock cylinder 8 and the garnish 9 can be easily and surely attached to the outer panel 13 side.

The present invention is not limited to the structure of this embodiment, and various design changes may be made without departing from the gist of the present invention. For example, the key lock cylinder 8 has been described as an example of a procedure in which the clip 16 is attached to the garnish 9 and then press-fitted into the clip 16. It may be attached to the tubular portion 25 of the garnish 9 in the assembled state.

[Effects of the Invention] As described above, according to the key lock cylinder mounting structure of the present invention, the cylinder is first temporarily assembled to the garnish via the clip. It is possible to position the key holes on the cylinder side and the cylinder side in advance. Then, in this state, the garnish is attached to the front panel of the trunk lid as a cylinder. After that, the cylinder is fixed by inserting a fixing member such as a screw into the engagement hole on the panel side and the mounting hole on the flange portion on the cylinder side.

Therefore, according to the present invention, the cylinder key hole and the garnish through hole are securely attached to the garnish and the trunk lid side after the cylinder is attached to the trunk lid side as before. Since it is positioned, there is no difficulty in positioning the key hole and the through hole of the garnish, and the centers of both holes are not displaced, so that workability and aesthetics can be improved. Further, since the cylinder is preliminarily assembled to the garnish, the cylinder side mounting hole may be displaced from the panel side engaging hole due to manufacturing or assembly error in the state where the garnish is mounted on the trunk lid side. Since the panel side engaging hole is formed in a size capable of absorbing manufacturing errors and the like, it can be securely fixed.
