As shown in FIGS. 1 to 5, the protrusion 54 protrudes intermittently in a ring shape so as to surround its outer edge from the outer surface of the head 51, and between the inner peripheral surface and the outer surface of the leg 52. The packing 40 fits into the donut-shaped groove.

The height of the protrusion 54 is formed lower than the thickness of the packing 40, and the inner diameter thereof is set larger than the outer diameter of the packing 40.
The protrusion 54 is for preventing the packing 40 from being crushed.
(Fastener 10 using packing 40)
A method of attaching the retainer 30 to the through hole 21 of the body 20 through the fastener 10 having the above-described configuration using the packing 40 having the above-described configuration will be described.

As shown in FIGS. 3 and 4, the leg portion 52 of the clip body 50 is inserted into the center hole 42 of the packing 40, and the packing 40 is attached to the clip body 50.
Next, the leg portion 52 to which the packing 40 is attached is inserted into the through hole 21 of the body 20 as shown in FIG.
When the leg portion 52 is inserted, as shown in FIG. 2, the retainer 30 is interposed via the clip main body 50 by sandwiching the body 20 from the front and back surfaces between the expanded locking portion 52 a and the head portion 51. It is held in the through hole 21 of the body 20.

At this time, the packing 40 is compressed between the head 51 of the clip body 50 and the body 20, as shown in FIG.
As shown in FIG. 9, the outer rib 43 is pushed by the head 51, the inner rib 44 is pushed by the body 20 from the opposite side, and the packing body 41 is elastically bent into a substantially V shape around the inner rib 44. The elastic restoring force closely contacts the head 51 and the body 20.

Further, since the inclined surface 43 a is formed on the inner side surface of the outer rib 43, the outer rib 43 bends obliquely in the outer circumferential direction of the packing body 41. Thereby, the load applied to the packing 40 during compression can be reduced by bending the outer rib 43 in the outer peripheral direction.
As shown in FIG. 2, the clip body 50 is fixed to the through hole 21 of the body 20 by inserting the screw 60 deeply into the communication hole 53 of the clip body 50.
