ジ部２が分離不能に固定される。<Prior Art> Conventionally, a rotary welding member 1 such as a stud shown in FIG. 10 or a fastener shown in FIG. 11 has a disc-shaped flange portion 2 and an engagement piece protruding laterally from the flange portion 2. Three and three
And the columnar portion 4 protruding from the center of the flange portion 2 were integrally molded of synthetic resin. Then, as shown in FIG. 12, the rotary welding member 1 is placed on the mounting plane A of the substrate 5 of synthetic resin or the like, and the abutting member 7 at the tip of the rotary welding machine 6 is contacted with the flange portion 2 of the rotary welding member 1. With the contacting member pressed against the mounting plane A, the engaging pieces 3, 3 of the rotary welding member 1 are inserted into the engaging grooves 8a, 8a of the engaging member 8 at the tip of the rotary welding machine 6 to move the engaging member 8 at high speed. When rotated, the engagement pieces 3 and 3 engage with the engagement grooves 8a, 8a, and the rotary welding member 1 rotates at high speed together with the engagement member 8. Therefore, the contact surfaces are melted and welded to each other by the rotational frictional heat between the mounting plane A and the back surface of the flange portion 2. When the rotation is stopped, the welded resin cools and solidifies, and as a result, the flange portion 2 of the rotary welding member 1 is inseparably fixed to the mounting plane A.

For example, in the case of a fastener, as shown in FIG. 14, the locking portions 11, 11 of the columnar portion 4 are pushed inward while being bent inward by the edge portion of the hole 12 of the plate 10 and passed through the hole 12. It is used to mount the plate 10 by locking the edges of the holes 12 by the step portions 11 ', 11' of the locking portions 11, 11 by elastic return of the locking portions 11, 11.

曲、膨出などの現象を生じたりする問題があった。However, since the conventional rotary welding member 1 is integrally formed of synthetic resin of the same material as described above, if the rotary welding member 1 is formed of a material having a high degree of melting so as to facilitate welding, There is a problem that the mounting strength in the columnar portion 4 becomes weak and the screw 9 comes off and the plate 10 comes off. On the contrary, if the rotary welding member 1 is made of a material having a high hardness to increase the mounting strength, Even if an attempt is made by rotary welding, the flange portion 2 does not melt easily, welding becomes difficult, and there arises a problem that the substrate 5 causes a phenomenon such as bending or swelling during pressing and rotation for a long time.
