に接合部分に空間が形成されるように構成する。(Structure) First, as shown in FIG. 1, a part of the base material 1 is cut and removed from one side of the base material 1 in the shape of a groove. Groove 2 to be formed
The cross-sectional shape of the groove is V-shaped with an obtuse angle near the bottom of the groove, and the remaining upper part has one side in a straight line shape perpendicular to the surface of the cutting base material, and the other side with the surface of the cutting base material. The shape is such that a straight line component that is parallel and extends in the opposite direction to the groove bottom and a straight line component that is perpendicular to the cutting base material surface from the end of the straight line component is formed so that a space is formed at the joint part when it is bent. Configure.
次いで第２図に示すように、前記溝２を介して

４を用いて基材が動かないようにする必要があ
る。 At this time, since the groove is formed deep so that the base material can be bent, the base material is almost cut at the bottom of the groove, and therefore, during the injection and solidification of the molten polyamide resin, It is necessary to use the fixing jig 4 to prevent the base material from moving.
ただし第３図に示すように、基材１の溝を形成
しない方の面に柔軟性を有するシート状物５を積
層しておけば、第４図に示すように固定用治具４
を用いないで接合することもできる。 However, as shown in FIG. 3, if a flexible sheet-like material 5 is laminated on the surface of the base material 1 on which the grooves are not formed, the fixing jig 4 can be stacked as shown in FIG.
It is also possible to join without using.
以上のようにして溶融ポリアミド樹脂を加圧注
入した後に該樹脂を固化させて、部材の接合を完
了する。 After the molten polyamide resin is injected under pressure as described above, the resin is solidified to complete joining of the members.
