However, in the above-described conventional grommet 100, the claw portion 102 projects in a rectangular shape toward the inside of the insertion hole 101, and the claw portion 102 has a thick structure, so that it is difficult to bend. There is a problem in that the insertion force of the engagement pin is high and it is difficult to attach the rear spoiler.

Therefore, the invention according to claim 1 has been made in view of the problems of the above-mentioned prior art, and the purpose thereof is to make the claw portion of the grommet into an arc shape inside the insertion hole. Another object of the present invention is to provide a fastener for a rear spoiler of an automobile, in which the insertion force of the engagement pin can be reduced by making it protrude. In addition to the object of the invention described in claim 1, the invention described in claim 2 has the following object.

That is, according to the second aspect of the present invention, the claw portion of the grommet has a thin structure so that the claw portion can be more easily bent.

[0008]

[Means for Solving the Problems]

(Features) The present invention is to achieve the above-mentioned object, and its contents will be described below using embodiments shown in the drawings. The invention according to claim 1 is characterized by the following points.

That is, each claw portion (34) of the grommet (30)
For example, as shown in FIGS. 1 and 6, when viewed from the inserting direction of the engaging pin (50), the engaging pin (50) is projected in an arc shape into the inserting hole (33). The invention described in claim 2 is characterized by the following points in addition to the configuration of the invention described in claim 1. That is, each claw portion (34) of the grommet (30) is, for example, as shown in FIGS.
It has a thin structure. (Operation) Therefore, according to the invention described in claim 1, the following operation is achieved.

That is, when the engaging pin (50) is inserted, the claw portion (34) is easily bent, and while securing a contact surface necessary for engagement,
The engagement pin (50) can be easily engaged with the grommet (30). Further, according to the invention of claim 2, in addition to the effect of the invention of claim 1 described above, the following effect is exhibited.

That is, each claw portion (34) of the grommet (30)
However, because of the thin structure, when the engagement pin (50) is inserted into the insertion hole (33) of the grommet (30), the claw portion (34) can be more easily bent.

As shown in FIGS. 10 and 15, the engagement pin 50 is provided with a hollow shaft portion 51 to be inserted into the insertion hole 33 of the grommet 30 and the height of the shaft portion 51. Engagement recess 52 that engages with the claw portion 34 provided in the insertion hole 33 of the 30.
And Further, as shown in FIGS. 10 to 12, the engagement pin 50 is arranged above the shaft portion 51 by sandwiching the dharma hole 41 provided in the lower portion of the rear spoiler 40 from above and below so that the engagement pin 50 is attached to the rear spoiler 40. Locking heads 53, 54 for locking are provided.

The locking heads 53, 54 are, as shown in FIGS. 10 to 12, a disk-shaped first locking head 53 extending outward from the upper end of the shaft 51, and A second disc-shaped member extending outward from the middle of the height of the shaft portion 51, separated from the first locking head portion 53 by the thickness of the dharma hole 41 formed in the rear spoiler 40. It consists of a stop head 54. As shown in FIGS. 1 and 2, the first locking head 53 has an outer diameter of a dharma hole.
The diameter is smaller than the maximum inner diameter of 41 and is larger than the minimum inner diameter of the dharma hole 41. Also, the first locking head
From the lower surface of the outer periphery of 53, as shown in FIGS. 10 to 12, a locking edge portion 531 extends obliquely downward from the outer periphery.

As shown in FIGS. 10 to 13, the second locking head 54 has an outer diameter substantially similar to that of the first locking head 53 described above, and the maximum diameter of the dharma hole 41 from the outer circumference thereof. A pair of locking protrusions 541 having a diameter larger than the inner diameter are provided so as to face each other. As shown in FIGS. 10 to 13, a bulging portion 542 is provided at an upper end of the locking protrusion 541.

On the upper surface of the outer peripheral surface of the engaging head 54 where the engaging projection 541 is not provided, as shown in FIG. 12, inclined surfaces 543 which incline downward toward the tip end face each other. There is a pair. Then, the first locking head 53 and the second locking head
54 is integrally formed with the shaft portion 51 by a synthetic resin or the like, and has flexibility and elasticity.

Below the second locking head 54 of the shaft portion 51,
As shown in FIGS. 2 and 10, the grommet 30 has an outer diameter smaller than the maximum inner diameter of the insertion hole 33 and larger than the maximum inner diameter of the claw portion 34, and the center portion is hollow. Has become. Then, in the middle of the height of the shaft portion 51, as shown in FIGS. 10 to 12, the claw portion 34 provided in the insertion hole 33 of the grommet 30 is provided.
An engaging recess 52 for engaging with is provided.

As shown in FIG. 2, the engaging recess 52 is formed by reducing the diameter of the shaft 51 toward the center of the shaft 51, and the outer diameter of the engaging recess 52 is the insertion hole of the grommet 30. The diameter is almost the same as the maximum inner diameter of the claw portion 34 provided inside 33. Also, the shaft
On the outer periphery of the lower end portion of 51, as shown in FIGS. (Method of attaching engagement pin) Engagement pin having the above-mentioned configuration
To attach the 50 to the rear spoiler 40, as shown in Figs. 1 and 2, the dharma hole opened at the bottom of the rear spoiler 40.
The first locking head 53 is inserted into the dharma hole 41 from below the maximum inner diameter portion of 41. At this time, the first locking head 53 has a dharma hole.
Although it passes through the maximum inner diameter portion of 41, the second locking head portion 54 cannot pass through the maximum inner diameter portion because the locking protrusion 541 of the second locking head portion 54 is caught on the lower surface of the dullama hole 41.

Then, the first locking head 53 and the second locking head 54
So that the dharma hole 41 is located between
Is slid toward the minimum inner diameter portion of the dharma hole 41.
Then, as shown in FIG. 16, the lower surface of the first locking head 53, the upper surface of the second locking head 54 and the locking projection 541 are engaged with each other with the dharma hole 41 sandwiched from above and below. The rear spoiler 40 can be held by the pin 50. (Method of Attaching Engagement Pin and Grommet) Next, to attach the engagement pin 50 holding the rear spoiler 40 to the grommet 30, insert the engagement pin 50 into the grommet 30 as shown in FIGS. Push it into the hole 33. Then, when the claw portion 34 of the grommet 30 enters the engaging recess 52 of the engaging pin 50, the claw portion 34 is elastically engaged with the engaging recess 52 as shown in FIG.
It projects inward and engages.

At this time, since the shaft portion 51 of the engagement pin 50 and the claw portion 34 of the grommet 30 are in point contact with each other as shown in FIG. 17, the engagement pin 50 is inserted into the insertion hole 33 of the grommet 30. Can be easily inserted. In this way, the engagement pin 50 holding the rear spoiler 40 can be engaged with the grommet 30 attached to the vehicle body 20, and the rear spoiler 40 can be attached to the vehicle body 20.

At this time, since the packing 60 is interposed between the second locking head 54 of the engaging pin 50 and the flange 35 of the grommet 30, as shown in FIG. Watertightness can be maintained. Also, as explained above,
Also packing between grommet 30 and car body 20
Since 70 is interposed, the watertightness between the two is also maintained.

Therefore, when the rear spoiler 40 is mounted on the vehicle body 20, rainwater or car wash water does not enter the grommet mounting holes 21 formed in the vehicle body 20, and water does not enter the trunk or the like. Can be prevented.
