うに、樹脂成形品ａ′の下穴ｂ′にナツトＣ′を直接圧
入する方法等がある。In such products, in order to implant the bolts and nuts into the resin molded product, conventionally, as shown in Fig. 5 (a),
A method of forming a pilot hole in a resin molded product A and press-fitting the bottom part d of a bolt C into the pilot hole. Insert the part,
Fix the edge of the hole B by biting into the threaded part using a caulking punch E, or directly insert the nut C' into the prepared hole b' of the resin molded product a' as shown in Figure (C). There are methods such as press-fitting.
（発明が解決しようとする問題点）
前記の植設方法のうち、（イ）の場合は、抜は強度の増

必要であり組付のサイクルが長時問掛ることになる。(Problems to be Solved by the Invention) Among the above-mentioned planting methods, in the case of (a), the insertion ID of the bolt C is knurled in order to increase the strength of the bolt C. C must be heated by high frequency, ultrasonic waves, a heater, etc. and press-fitted into the pilot hole of resin molded product A, which requires expensive equipment and requires a cooling process, resulting in a long assembly cycle. It will take a while.
（ロ）の場合は、ねじ満が通気路となって気密を要求さ
れる部品には不向きであり、ボルトＣの頭部を非円形（
回り止め）にするため組付けの自動化が困難となる。In the case of (b), the screw hole becomes a ventilation path and is not suitable for parts that require airtightness, and the head of bolt C is not circular (
Automation of assembly is difficult because it is non-rotating.
一方、（ハ）の場合は、常温で単に圧入するだけである
から抜は強度が不足することになる。On the other hand, in case (c), the strength is insufficient when removed because it is simply press-fitted at room temperature.
本発明は、このような従来方法の不都合を解消したボル
ト等の植設方法を提供しようとするものである。The present invention aims to provide a method for installing bolts, etc., which eliminates the disadvantages of such conventional methods.
（問題点を解決するための手段）
上記の問題点を解決するための手段として、この発明は
、樹脂成形品に植設するボルト等の円柱形挿着部の周面
の一部に平坦面に形成し、この平坦面を除く局面にはロ
ーレット加工を施し、前記樹脂成形品の下穴は前記ボル

部を常温で圧入することを要旨とするものである。(Means for Solving the Problems) As a means for solving the above problems, the present invention provides a flat surface on a part of the circumferential surface of a cylindrical insertion part such as a bolt implanted in a resin molded product. The curves other than the flat surface are knurled, and the pilot hole of the resin molded product has the same shape as the cross section of the cylindrical insertion part before knurling for the bolt, etc. The gist is to press-fit the cylindrical n-tube portion, such as the bolt, into the hole at room temperature.
（実施例）
以下、図示の実施例によりこの発明方法を具体的に説明
する。(Example) Hereinafter, the method of the present invention will be specifically explained with reference to the illustrated example.

がそれぞれ茄されている。In the figure, 1 is a bolt to be implanted in a resin molded product 2, and its cylindrical insertion portion 1a has flat surfaces 1b and Ic that face each other.
and knurling 1d between adjacent flat surfaces.
are boiled respectively.
前記樹脂成形品２には下穴２ａが形成され、ぞの平面形
状は前記ボルト１のローレット加工１ｄを施す前の円柱
形挿着部１ａの断面形状と同じ、即ちローレット加工１
ｄを施した円柱形挿着部より若干小さ目に形成されてい
る。A prepared hole 2a is formed in the resin molded product 2, and the planar shape of the hole 2a is the same as the cross-sectional shape of the cylindrical insertion portion 1a of the bolt 1 before knurling 1d, that is, the knurling 1.
It is formed slightly smaller than the cylindrical insertion part shown in d.
なお、下穴２ａの上縁部には、前記ボルト１のフランジ
１ｅが嵌まる座ぐり穴２ｂが形成されている。Note that a counterbore hole 2b into which the flange 1e of the bolt 1 is fitted is formed at the upper edge of the pilot hole 2a.

強く食い込むので抜は強度が強く、また、円柱形挿着部
１ａに平坦面１ｂ、１ｃが形成され、この弊端面がボル
ト１の回り止め作用をなすので回転に対するトルクが増
大して好都合である。The bolt 1 is fixed by being press-fitted into the prepared hole 2a of the resin molded product 2 at room temperature. At this time, the bolt 1 is automatically supplied and can be press-fitted into the pilot hole 2a of the resin molded product 2 using a press machine with a simple structure. Pilot hole 2a
The bolt 1 press-fitted into the cylindrical insertion part 1a has a strong strength when removed because the knurled part 1d bites into it strongly, and flat surfaces 1b and 1c are formed on the cylindrical insertion part 1a, and these end faces prevent the bolt 1 from rotating. This is advantageous because the torque for rotation increases.
