させることによつて行なわれている。b. Prior Art Conventionally, this type of bumper skin support structure has been constructed as shown in FIGS. 1 and 2 (see "Passenger Car Body", Vol. 13, Sankaido Edition Automotive Engineering Complete Book).
In both figures, 1 is a front panel of the vehicle body, 2 is a side member which is a front strength member of the vehicle body, 4 is a bumper stay fixed to the side member 2 with bolts B,
Reference numeral 6 designates the bumper body, which is composed of a U-shaped reinforcement 8 fixed to the bumper stay 4, and a resilient resin bumper skin 10 that is supported by the reinforcement 8 and absorbs collision energy by elastically deforming in the event of a light collision. It's on. To support this bumper skin 10, as shown in Fig. 2, a long hole 8a in the vehicle width direction is formed in the reinforcement 8, and a bolt insertion hole 10a is bored in the bumper skin 10 at a portion corresponding to the long hole 8a. This is accomplished by inserting a stepped decorative bolt 12 into this hole 10a and screwing a nut 16 onto the bolt threaded shaft portion 12a via a spring washer 14.

う問題がある。c.Object of the invention However, in this way, the stepped decorative bolt 12
Since the bumper skin 10 is supported on the reinforcement 8 by
If the molding accuracy of the reinforcement plate thickness H 2 varies (particularly when controlling the thickness of the bumper skin 10 is difficult) or the tightening torque of the decorative bolts 12 is too strong, the bumper skin 10 may not slide smoothly against thermal deformation. First, the bumper skin 10 becomes wavy, deteriorating the appearance quality, and managing the tightening of the bolts 12 becomes difficult. Furthermore, if the decorative bolts 12 are tightened so that they float against the bumper skin 10, not only will the appearance deteriorate, but also abnormal noise will be generated between the bumper skin 10 and the decorative bolts 12 during driving, which will also reduce quality. be.
更に段付装飾ボルト１２という特殊なボルトを
数個使用するため、高価なものにつくという問題
もある。 Furthermore, since several special bolts called stepped decorative bolts 12 are used, there is also the problem that they are expensive.

である。d.Structure of the Invention In order to achieve the above object, the present invention provides a bead part along the vehicle width direction in the bumper reinforcement, stores and fixes the slide rail part of the first clip in this bead part, and covers the bumper surface. The insertion tip of the second clip inserted into the second clip is locked to the slide rail portion so as to be movable in the vehicle width direction.

滑に行なわれる。e. Effect: The bumper skin is supported by the reinforcement by the first and second clips, and the second clip follows the thermal deformation of the bumper skin by sliding on the slide rail portion of the first clip. This prevents the bumper skin from waving, but when the first clip engages with the second clip, the head of the first clip is elastically deformed to contact the bumper skin, so the bumper skin and the first clip are in contact with each other. There is no floating between the two clips, the engagement force is weaker than that of bolt/nut fastening, and the first clip slides smoothly relative to the slide rail portion of the second clip.

ｃに係止されている。f Example In FIGS. 3 and 4, the bumper body 20
The bumper skin 24 consists of a reinforcement 22 fixed to the vehicle body side via a bumper stay as in the past, and a bumper skin 24 supported by this reinforcement 22. The support structure of the bumper skin 24 includes a first clip 26 made of resin and This is done by a combination of the second clips 28. Specifically, a bead portion 22a extending in the vehicle width direction is formed in the reinforcement 22, and a clip insertion hole 22c is bored in the bottom surface 22b of the bead portion 22a. A slide rail portion 26a of the first clip 26 is accommodated in this bead portion 22a, and a clip piece 26b is inserted into the clip insertion hole 22a.
It is locked at c.

ようになつている。 On the other hand, the slide rail portion 26 of the bumper skin 24
A clip insertion hole 24a is drilled in a portion corresponding to approximately the center of a, a second clip 28 is inserted into this insertion hole 24a, and a locking piece 28a at the insertion tip of the second clip 28 is inserted into the first clip. The hook pieces 26c on both sides of the slide rail portion 26a are slidably engaged with the inside of the slide rail portion 26a.
このとき、第２クリツプ２８の頭部２８ｂの周
縁面２８ｃがバンパ表皮２４に弾性変形した状態
で当接するようになつている。 At this time, the peripheral surface 28c of the head 28b of the second clip 28 comes into contact with the bumper skin 24 in an elastically deformed state.
従つて、バンパ表皮２４が熱変形すると第２ク
リツプ２８が第１クリツプ２６のスライドレール
部２６ａに沿つてスライドし、バンパ表皮２４の
波打ちを防止する。 Therefore, when the bumper skin 24 is thermally deformed, the second clip 28 slides along the slide rail portion 26a of the first clip 26, thereby preventing the bumper skin 24 from waving.
そして、バンパ表皮２４やレインフオース２２

こともない。 And bumper skin 24 and rain force 22
Even if the molding accuracy varies, the molding errors are absorbed by elastic deformation of the peripheral surface of the head 28b of the second clip 28. Therefore, the bumper skin 24
The second clip 28 does not float up and spoil the appearance, and since the first clip 26 and the second clip 28 are engaged with the hooking piece 26c and the locking piece 28a, the followability against thermal deformation is improved. It will not be damaged.
また、第１、第２の各クリツプ２６，２８は樹
脂製であるため、従来のような特殊な装飾ボルト
を使用する必要がなく、しかも組付に際しては、
レインフオース２２に第１クリツプ２６を係止し

ので、従来のようにレインフオース２２の内側で
ナツト締めするということもなく、組付作業性も
良好となり安価に製作できる。 In addition, since the first and second clips 26 and 28 are made of resin, there is no need to use special decorative bolts like in the past, and when assembling,
After locking the first clip 26 to the reinforcement 22, the bumper skin 24 locks the reinforcement 22.
Since the second clip 28 is inserted from the outside while covering the reinforcement 22, there is no need to tighten nuts inside the reinforcement 22 as in the conventional case, and the assembly workability is improved and manufacturing is possible at low cost.
なお、第２クリツプ２８の係止片２８ａを多段
に形成しておけば、第２クリツプ２８の係合力の
コントロールが容易になると共に、バンパ表皮２
４やレインフオース２２の成形誤差を吸収するの
も容易になる。 Note that if the locking pieces 28a of the second clip 28 are formed in multiple stages, the engagement force of the second clip 28 can be easily controlled, and the bumper skin 28 can be easily controlled.
4 and reinforcement 22 can be easily absorbed.
