DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on the illustrated embodiments.

1 to 4 show an embodiment of a side sill scuff mounting structure according to the present invention. In the figure,
Reference numeral 1 denotes a side sill scuff provided at a lower portion of an entrance / exit of an automobile, and the side sill scuff 1 is detachably attached to an upper portion of an outer panel (side sill outer) 2 of a side body.

However, the side silscuff 1 is
As shown in FIG. 1, the joint flange portion 2 of the outer panel 2 is formed in a strip extending along the front-rear direction of the automobile.
The ridge portion 3 disposed on the a side, the flange portion 4 provided on the outer side edge of the ridge portion 3, and a plurality of pieces (four pieces in this embodiment) integrally provided on the lower surface of the flange portion 4. ) And the projections 5). The protruding portion 3 is formed in a curved shape protruding upward, and thereby covers the upper side of the joint flange portion 2a of the outer panel 2.

As shown in FIGS. 1 and 3, the flange portion 4 extends outward from the ridge portion 3,
It is formed wide along the upper surface of the outer panel 2.
The tip of the flange portion 4 is slightly bent downward so as to come into contact with the upper surface of the outer panel 2, so that a gap is formed between the lower surface of the flange portion 4 and the upper surface of the outer panel 2. There is a gap S between the tip of the flange portion 4 and the upper surface of the outer panel 2, and when the side sill scuff 1 is detached, a thin plate-like body is inserted into the gap S to move upward (in the direction of arrow a in FIG. 3). ) Is configured to twist.

On the other hand, the projection 5 has ribs 6, 7, 8 and 9 formed in a cross shape in cross section, and is spaced at regular intervals in the longitudinal direction of the flange portion 4 (front-back direction of the vehicle body). It is arranged. Further, the tip ends of the protrusions 5 are formed by tapering the lower end portions of the ribs 6 and 7 so that they can be easily inserted into a mounting hole described later when the side sill scuff 1 is assembled. Of these ribs 6, 7, 8 and 9, one rib 6 arranged on the side of the protrusion 3 is provided with a claw portion 10 that engages with a mounting hole described later. Outer panel 2 when the side silscuff 1 is installed
The projection 5 is fixed by being hooked on the side.

Further, the upper surface portion 10a of the claw portion 10 and the lower surface portion 8a of the rib 8 located on the opposite side of the claw portion 10 are cut obliquely as shown in FIGS. The protrusions 5 are formed on inclined surfaces in the same direction, and when the flange 4 is pryed up, the claws 10 and the ribs 8 move in the direction of arrow b, and the projections 5 are separated from the outer panel 2. That is, the upper surface portion 10a of the claw portion 10
Is inclined upward from the outer side surface toward the axis, and the lower surface portion 8a of the rib 8 is inclined upward from the axis toward the outer side surface. The upper portions of the ribs 6 and 8 have a function of restricting the lateral movement of the side sill scuff 1, and the ribs 7 and 9 have a function of restricting the movement of the side sill scuff 1 in the vehicle front-rear direction.

The outer panel 2 of the side body
Corresponding to the protrusion 5 on the side silscuff 1, a plurality of (four in this embodiment) mounting holes 11 are formed at regular intervals in the front-rear direction of the vehicle body. Moreover, these mounting holes 11 are formed as round holes having a size into which the protrusion 5 can be inserted.

To attach the side sill scuff 1 of this embodiment to the outer panel 2 of the side body, first, the lower surface of the flange portion 4 of the side sill scuff 1 is attached to the outer panel 2.
While holding toward the side, the tip ends of the protrusions 5 are inserted into the corresponding mounting holes 11 of the outer panel 2 from above. Then, when the claw portion 10 of the rib 6 is hooked on the lower surface of the outer panel 2 located at the peripheral portion of the mounting hole 11, the side silscuff 1 is firmly fixed to the outer panel 2 and attached to the side body of the entrance / exit (see FIG. 3). ).
The side silscuff 1 in this state has ribs 6 of the protrusions 5,
Lateral movement is restricted by the upper part of the ribs 8,
The movement of the vehicle body in the front-rear direction is restricted by this, and not only the upward pull-out is blocked, but also the horizontal movement is blocked.

In order to detach the side silscuff 1 from the outer panel 2 of the side body, the flange portion 4
Insert a thin plate-like body into the gap S between the tip of the outer panel 2 and the upper surface of the outer panel 2 and pry it in the direction of arrow a in FIG. Then
Since the rib 8 and the claw portion 10 move in the direction of the arrow b and come off from the peripheral edge portion of the mounting hole 11, the protrusion 5 can be pulled out (see FIG. 4).

In the mounting structure of this embodiment, four projections 5 having ribs 6, 7, 8, 9 having a cross-shaped cross section are integrally provided on the lower surface of the flange portion 4 of the side silscuff 1.
Further, the ribs 6 are provided with the claw portions 10, and the projections 5 are inserted into the mounting holes 11 on the outer panel 2 side and the claw portions 10 are hooked on the peripheral edge portion, so that the side silscuff 1
Since it is fixed to the outer panel 2, it can be attached at an accurate position with one touch without using a clip or the like as a separate component. Moreover, the upper surface portion 10a of the claw portion 10
Also, since the lower surface portion 8a of the rib 8 is formed in an inclined surface shape, when the flange portion 4 is lifted up by using the clearance S, the rib 8 and the claw portion 10 are disengaged from the mounting hole 11 and relatively easily. The protrusion 5 can be pulled out. Further, since the mounting hole 11 on the outer panel 2 side is a round hole, there is no need to use a special punch, and the manufacture and maintenance of the mold are easy.

The embodiment of the present invention has been described above.
The present invention is not limited to the embodiments described above, and various modifications and changes can be made based on the technical idea of the present invention.

For example, in the above-mentioned embodiment, the mounting hole 11 having a round hole is provided on the outer panel 2 side of the side body. However, when the side sill scuff 1 to be applied has a long overall length, resin In order to absorb the expansion and contraction, a part of the mounting hole 11 may be changed to a long hole. Further, the number of the protrusions 5 installed is not limited to four, and can be appropriately changed according to the length of the side silscuff 1.

[0019]

As described above, in the side sill scuff mounting structure according to the present invention, a plurality of mounting holes are arranged in the outer panel of the side body at intervals in the front-rear direction, and the flange portion is provided at the side edge of the side sill scuff. A plurality of protrusions having ribs having a cross-shaped cross section are arranged at intervals in the longitudinal direction on the lower surface of the flange portion, and a claw portion that engages with the mounting hole is provided at one location of the rib. Since the side silscuffs are removably attached to the outer panel of the side body by inserting the protrusions into the mounting holes respectively, it is possible to eliminate the mounting clip for another component required in the conventional mounting structure. Cost reduction can be achieved by reducing man-hours and the number of parts. Further, in the mounting structure of the present invention, since the rib shape of the protrusion provided on the lower surface of the flange portion is formed in a cross-shaped cross section, the side silscuff can be mounted at a quick and accurate position without using any positioning means. Is possible,
Installation workability can be improved.
