エース部品Ｂを固定することが行われている。Prior Art Conventionally, for example, when attaching a face part B to a vehicle finisher A (see Fig. 3 a and b), a boss hole a 1 formed in the plate surface of the finisher A is used.
Insert the protruding part b 1 into the back of the face part B (see Fig. 4 a, b, c), press the pre-heated press rod P against the protruding end side, and gradually remove the protruding part b 1 By melting from the tip side, the boss hole a 1
The face part B is fixed by forming a bridging part b2 on the edge (see FIG. 4d).

な熱伝導を妨げるなどの不具合がある。Problems to be Solved by the Invention However, with this mounting method by deforming the protrusion b1 , it is difficult to maintain the heating temperature of the press rod P at an appropriate level, and if the temperature is low, the protrusion b1 may not be sufficiently melted. As a result, insufficient molding of the bridging portion b 2 causes wobbling in the mounting state of the face part B. Also, if the heating temperature is too high, the protrusion b 1 will be excessively melted, resulting in insufficient mounting strength, and furthermore, the pressing rod Since it is in a stopped state without rotating, there are problems such as molten resin adhering to its tip and hindering tight heat conduction.

にされている。Means for Solving the Problems In the method for fixing a mounting body according to the present invention, a plurality of protrusions are formed protruding at predetermined intervals on the back surface of a mounting body formed of thermoplastic synthetic resin into a substantially box shape. is inserted into a relatively large boss hole of the object to be attached, and a rotating metal rod with a hemispherical tip is pressed against the tip of the protrusion by rotating it. The frictional heat generated by the pressing softens the tip end of the protrusion, causing it to expand and deform more than the hole edge of the boss hole, and the frictional heat generated by the rotational pressure of the rotary rod also softens the hole edge of the boss hole. The mounting body is integrally fixed to the mounting body by being fused with the softened resin of the protrusion and also press-fitted into the boss hole.

う強固に固定できるようになる。Function: With this method of fixing the mounting body, the tip end of the protrusion is softened by the frictional heat generated as the rotary rod rotates and presses, so there is no need to preheat the rotary rod and maintain it at a predetermined temperature. Since the resin can be heated and softened uniformly at all times, and the softened resin does not stick locally to the rotating rod, a stable mounting condition can be obtained. In addition, by using a rotating rod with a hemispherical end face hollowed out, the resin softened by frictional heat does not spread excessively to the surrounding area, and can be deformed into a hemispherical shape that is approximately the same shape as the end face of the rotating rod. It is possible to accurately form a flange portion that widens more than the edge of the hole, and it becomes possible to reliably press fit the softened resin into the hole of the boss hole.
Furthermore, the tip side of the protrusion and the hole edge of the boss hole are heated and softened by the frictional heat generated by rotating and pressing the rotary rod, and are integrated by fusing with each other.
In addition, by press-fitting a portion into the boss hole to fill the gap between the protrusion and the boss hole, it is possible to firmly fix the protrusion so that it will not loosen or rattle even after long-term use.

The finisher A is formed into a plate shape from ABS resin or the like, and a plurality of horizontally elongated holes a1 serving as boss holes are provided on the plate surface. Note that it is desirable to locally form a thick part a2 around the horizontally long hole a1 that is thicker than other parts. The face part is formed of colored methyl methacrylic resin or the like into a hollow box shape, and on the back side thereof, a plurality of protrusions B 1 to be inserted into the oblong holes A 1 of the finisher A are integrally protruded at a predetermined interval. has been done. The horizontally elongated hole a1 is formed to be slightly larger than the external shape of the protrusion b1 in order to make it easier to assemble the face part B to the finisher A.
It is formed to be long so that a desired length protrudes toward the back side of the finisher A when it is inserted into the finisher A1 .

損なうことがない。 Face part B is assembled by inserting protrusion b 1 into oblong hole a 1 so that the tip of the shaft protrudes from the back side of finisher A, and with it facing upward, press the metal rotating rod T against the tip. . As this rotating rod T, it is preferable to use a rod having a hemispherical hollow t1 on the tip surface and having its surface smoothed by chrome plating, etc., while rotating the rotating rod T at a constant speed. When the pressure is lowered, the protrusion b 1 softens from the tip end side due to the frictional heat generated due to the rotational pressure, so that the rotating rod T
It gradually deforms according to the shape of the tip of the boss hole a1, and deforms into a hemispherical shape that is wider than the hole edge of the boss hole a1 . When the rotational pressure of the rotary rod T is continued until the tip end slightly bites into the thick part a2 on the back side of the finisher A, the resin forming the finisher A also rotates on the edge of the boss hole a1. It is heated and softened by the frictional heat generated as a result of rotating and pressing with a rod, and mixes with the resin of the protrusion b 1 to be fused and integrated. Therefore, the tip end side of the protrusion b 1 is formed as a flange b 2 that is in close contact with the hole edge of the boss hole a 1 and bridged in the shape of a screw head. In addition, a portion b3 of the softened and fused resin is press-fitted into the boss hole a1 to fill the gap between the boss hole a1 and the protrusion b1 . Therefore, the face part B is securely fixed to the finisher A by the engagement of the flange part b2 with the edge of the boss hole a1 and the deformed part b3 that fills the inside diameter of the boss hole a1 , and the deformed part b3 is Since it is not exposed on the surface side, the surface properties of finisher A are not impaired.

Can be widely applied. Further, a step b 4 may be provided on the protrusion b 1 to position the protrusion b 1 for insertion into the boss hole a 1 . Moreover, when the thickness of the object to be attached is sufficient, it is not necessarily necessary to form the local thick portion a2 .

変形による取付体の固定方法。1. Insert a plurality of protrusions formed protruding from the back side of a mounting body formed in a substantially box shape from thermoplastic synthetic resin at a predetermined interval into a relatively large boss hole of the mounting body, A rotary metal rod with a hemispherical end face hollowed out is rotated and pressed against the tip of the protrusion, and the frictional heat generated by this rotational pressure softens the tip of the protrusion and creates a boss hole. At the same time, the hole edge of the boss hole is also softened by the frictional heat generated by the rotational pressure of the rotating rod, and is fused with the softened resin of the protrusion, and is also press-fitted into the hole of the boss hole. 1. A method for fixing a mounting body by plastic deformation of a protrusion, characterized in that the mounting body is integrally fixed to a body to be mounted.
