係合突起５を突設した構造となっている。<Prior art> (Fig. 5.6) Conventional resin i'J welding members for rotary welding to a resin plane, such as studs 1 and fasteners 2, are shown in Figs. 5 and 6.
As shown in the figure, it has a structure in which a disk-shaped flange part 4 of a constant thickness is protruded from one end of the column part 3, and an engaging protrusion 5 is protruded from the peripheral edge of the flange part 4 on the opposite side to the welding surface. .

As shown in the figure, the rotary jig 7 holds and presses the stud 1 or the damper 2 at the position where it should be mounted on the resin mounting board 6, and the engagement protrusion 5 is inserted into the notch 7a of the rotary jig 7. Engage and rotate at high speed.

じていた。Problems to be Solved by the Present Invention> However, in the stud 1 or fastener 2 having the above structure, due to the difference in linear expansion coefficient between the flange part 4 and the mounting board 6, the molten part cools. Due to the difference in shrinkage rate during curing and shrinkage, as shown in FIG. A ``tree phenomenon'' was occurring.
このため、取付基板６の裏面が外観量として用いられる
場合には、この“裏つツリ現客”のために外観性を著し
く低下させていた。For this reason, when the back surface of the mounting board 6 is used as an appearance quantity, the appearance quality is significantly deteriorated due to this "back-and-forth appearance".

。OBJECT OF THE INVENTION The present invention aims to reduce the occurrence of such "underprint dyeing" which causes deterioration of appearance as much as possible, by modifying the shape of the flange part to reduce the difference in coefficient of linear expansion. The purpose of the present invention is to provide a resin rotary welding member with reduced effects.

め、硬化収縮時にフランジ部の外周側が取付基板に変形
追従して、湾曲やシワを生じることが少なくなる。Effect of the above means> As the wall thickness of the flange portion is gradually reduced toward the outer circumference, even if there is a difference in linear expansion coefficient between the flange portion and the mounting board, the wall thickness of the flange portion is reduced toward the outer circumference. This reduces the possibility of the outer peripheral side of the flange portion deforming and following the mounting substrate during curing and shrinkage, resulting in less curvature and wrinkles.
く本発明の実施例〉（第１〜４図） 以下、図面に基づいて本発明の詳細な説明する。Embodiments of the present invention> (Figures 1 to 4) Hereinafter, the present invention will be described in detail based on the drawings.
第１．２図はそれぞれ本発明による樹脂製回転溶着部材

ンジ部１１は外周方向に向って肉厚が漸減している。Fig. 1 shows a stud integrally molded from synthetic resin, which includes a cylindrical column part 10, a disc-shaped flange part 11 protruding from one end thereof, and a peripheral edge of the flange part 11 on the side opposite to the rFJW surface. The flange portion 11 includes a plurality of engaging protrusions 12 protruding from the flange portion 11, and the thickness of the flange portion 11 gradually decreases toward the outer circumferential direction.
第２図は柱部１０に係合用の弾性突起１４．１４を備え
た留め具で、他の部分の構造は第１図と同一である。FIG. 2 shows a fastener having elastic protrusions 14, 14 for engagement on a column 10, and the structure of other parts is the same as that in FIG. 1.

される。As shown in Fig. 3, hold the RW member (stud or fastener) made of resin with the rotating jig 16, and cut out the notch 1 of the rotating jig 16.
When the engaging protrusions 12.12 are engaged with 6a and 16a and the flange portion 11 is pressed against the synthetic resin mounting board 17 and rotated at high speed, the contact surfaces are melted and welded by frictional heat. Thereafter, the welded portion cools and hardens, and is fixed as shown in FIG.

る″衷つッリ現象″の発生が少なくなる。In this cooling hardening, the flange portion 11 and the mounting board 17
Even if there is a difference in linear expansion coefficient between the flange portion 1
Since the wall thickness of the flange 11 is smaller on the outer circumferential side, the flange portion 11 is more easily deformed and follows the deformation of the mounting board 17 during curing and shrinkage, resulting in bends and wrinkles on the back surface of the mounting board 17. The occurrence of ``slip phenomenon'' is reduced.
