By the way, the key cylinder mounting structure is required to have a strong mounting strength so that the key cylinder does not swing against external force in order to prevent theft. However, in the prior art described in Japanese Utility Model Laid-Open No. 4-84681, the key cylinder 005 is supported only by the thickness of the outer panel 003 in the mounting hole 002. When an external force that swings in the direction is applied, the key cylinder 005 swings easily, and there is a problem that sufficient mounting strength cannot be obtained. In this structure, to improve the mounting strength of the key cylinder 005, the mounting hole 002 on the back side of the outer panel 003 is required.
, It is necessary to provide a thick reinforcing material around the periphery of the device, which causes a problem that the number of parts increases, which increases the manufacturing labor and cost.

In the prior art described in Japanese Utility Model Laid-Open No. 4-119070, the lock cylinder 03 is supported by the cylindrical lock cylinder mounting portion 04, so that the lock cylinder 03 swings on the lock cylinder 03. Even if such an external force is applied, the lock cylinder 03 does not easily swing, but since the lock cylinder mounting portion 04 is formed on the resin-made outdoor side door handle portion 01, when a large external force is applied, There is a possibility that the lock cylinder mounting portion 04 is damaged and the lock cylinder 03 swings. When attaching the outdoor side door handle portion 01 to the outer panel, first, the lock cylinder 03 is attached to the resin outdoor side door handle portion 01, and the resin outdoor side door handle portion 01 is attached to the outer panel. In this mounting method, the positioning of the lock cylinder 03 and the resin outdoor side door handle part 01 is easy, but when the resin outdoor side door handle part 01 is mounted on the outer panel, the lock is provided on the resin outdoor side door handle part 01. If the accuracy of the entire resin outdoor side door handle portion 01 as a molded component or the accuracy of the mounting leg 01a is not accurately obtained because the mounting leg 01a is used, the lock cylinder 03 and the rear side of the outer panel are not shown. There is a possibility that the mounting position with the operating rod for operating the lock mechanism may shift, and in this case, the transmission of the operating force may not be performed smoothly.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to improve the mounting strength of a key cylinder and facilitate alignment of a key cylinder, an outer panel, and a finisher. .

On the left and right sides of the key operation hole 25, columnar bosses 22 are erected from the corners at the lower end of the finisher 2, and bolts 221 are embedded in the bosses 22. Further, a plurality of reinforcing ribs 22f are formed on the outer periphery of the boss portion 22. Below the key operation hole 25, a semi-cylindrical supporting rib 27 for supporting the outer peripheral surface of the key cylinder 3 is provided upright. A rib 28 is provided upright. A retainer 2r made of an elastic material such as rubber is attached to the outer periphery of the finisher 2.

Next, the configuration of the key cylinder 3 will be described.
The key cylinder 3 includes a cylinder body 31 having a cylindrical shape as shown in the figure, and a flange 32 projecting left and right at an intermediate portion of the cylinder body 31. As shown in FIG. 1, the flange 32 is formed at an angle corresponding to the slope 15 a in which the key cylinder insertion hole 13 is formed in the recess 15, and an upwardly facing surface thereof contacts the slope 15 a. The surface 32t is set. Further, a bolt hole 34 is formed in the flange 32. The bolt holes 34 are formed in the distal opening 3 having different shapes.
41 and a proximal opening 342. That is, while the distal opening 341 is circular, the proximal opening 342 is vertically long and oblong.
It has a continuous shape in which the vertical diameter increases from 1 toward the proximal opening 342. Further, the diameter of the distal end side opening 341 is formed slightly larger than the diameter of the bolt 221. An operating portion 35 for transmitting an operating force to a remote control mechanism of a door lock device (not shown) is provided at a base end portion 31a of the cylinder body 31.
Although not shown, a key insertion hole is provided in the distal end surface 31b of the.

As shown in FIG. 1, a cushion member 226 is provided on the outer periphery of a flange 25f provided around the key operation hole 25.

Next, the procedure for mounting the key cylinder 3 will be described. First, the key cylinder 3 is temporarily held by the finisher 2. This temporary holding is performed by the 2 provided on the finisher 2.
The two bolts 221 are inserted into the bolt holes 34 formed in the flange 32 of the key cylinder 3,
And the flange 32 is brought into contact with the pressure receiving surface 223 at the tip of the boss portion 22.

This temporary holding state is shown by a solid line in the sectional view of FIG. That is, in this temporary holding state, the tip end (right side in the figure) of the key cylinder 3 is lowered by its own weight, and the upper end of the tip end opening 341 is hooked on the upper part of the bolt 221. Since the key cylinder 3 can be temporarily held in the finisher 2 only by inserting the bolt 221 into the flange 32 of the key cylinder 3 in this manner, the mounting operation is performed by moving the finisher 2 and the key cylinder 3 in an assembled state. It is excellent in mounting workability. As described above, high mounting workability can be obtained without particularly providing means for assembling.

Next, the finisher 2 is attached to the outer panel 1 with the key cylinder 3 kept in the temporary holding state shown by the solid line in FIG. When attaching the finisher 2, first, the base end 31 a of the cylinder body 31 is inserted into the key cylinder insertion hole 13 provided in the outer panel 1 so that the operation portion 35 projects to the back side of the outer panel 1, and The contact surface 32t is brought into contact with the inclined surface 15a on the surface of the outer panel 1, and further, the tip of the bolt 221 is inserted into the mounting hole 131 of the outer panel 1, and the nut 222 is gradually fastened from the back side of the outer panel 1. As a result, the cylinder main body 31 moves relative to the finisher 2.

In this case, since the bolt hole 34 of the flange 32 of the key cylinder 3 is formed to have a large diameter with respect to the bolt 221, the operation unit 35 at the base end of the key cylinder 3 is fixed to a remote control mechanism (not shown). Position. Then, after disposing the cylinder body 31 at the regular position, the nut 22
2 is further strengthened, and finally, the nut 222 and
The flange 32 and the outer panel 1 are fastened together with the pressure receiving surface 223 of the boss portion 22, and the key cylinder 3 is attached. FIG. 5 shows the mounting state at this time. Finally, the mounting pins 24 provided on the finisher 2 are inserted into the finisher mounting holes 121, and the mounting of the finisher 2 is completed. Here, the cylinder body 31 of the key cylinder 3
Of the key operation hole 25, the tip surface 31b of the key operation hole 25 can move relative to the finisher 2. Therefore, even if the relative position between the outer panel 1 and the finisher 2 is slightly deviated within the range of the tolerance, the final position of the finisher 2 is determined after the cylinder main body 31 is disposed at a regular position with respect to the remote control mechanism on the back side of the outer panel 1 Even if the position of the finisher 2 is slightly displaced after the initial mounting, the key operation hole 25 is arranged at a position where the key can be operated with respect to the key insertion hole provided in the tip end surface 31b of the cylinder body 31. become.

In the key cylinder 3 mounted as described above, when a force is applied to sway the key cylinder 3 to swing the axis, the left and right flanges 32 of the key cylinder 3 The key cylinder 3 hardly swings with respect to the outer panel 1 because the key cylinder 3 is closely attached to the outer panel 1 by the contact surface 32t, is fastened together with the outer panel 1, and is integrally attached to the outer panel 1. Also,
Since the finisher 2 is in contact with the flange 32 at the pressure receiving surface 223 of the boss portion 22, it is difficult to be damaged even when a large input is applied.

In this embodiment, the bolt 221 provided in the finisher 2 is inserted into the mounting hole 131 of the outer panel 1 having a larger diameter than the bolt 221 and the bolt hole 34 of the key cylinder 3. The positioning of the finisher 2 with respect to the key cylinder 3 can also be absorbed since the positioning of each key cylinder 3 is easy and the front end surface of the key cylinder 3 is abutted against the flange 25f of the key operation hole 25.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and a design change or the like may be made without departing from the gist of the present invention. Even if present, it is included in the present invention. For example, in this embodiment, an example in which the present invention is applied to a back door is described, but the present invention can be applied to other doors such as a side door and a trunk lid. Further, in the present embodiment, an example in which the two flanges 32 are provided on the key cylinder 3 has been described, but the number of the flanges may be three or four, which is larger than two. Further, in the embodiment, the flange 32 has an angle with respect to the direction orthogonal to the axis of the key cylinder 3, but this angle can be set arbitrarily.
