本考案は樹脂成形品に一体に突設された成形ボ
ス装置に関するもので、前記ボスに部品を取付け

る。[Detailed Description of the Invention] The present invention relates to a molded boss device that is integrally provided on a resin molded product, and is intended to improve the mounting accuracy when attaching parts to the boss.
第１図に示すように樹脂成形品１の取付面に対
して複数のボス２が垂直に突設されている場合、
部品３の位置決め精度は十分であるが、第２図に
示すように成形品１′の取付面に対してボス２′が

分な位置決めができないという欠点があつた。こ
こで、４はタツピングビスである。 As shown in FIG. 1, when a plurality of bosses 2 protrude perpendicularly to the mounting surface of the resin molded product 1,
Although the positioning accuracy of the part 3 is sufficient, if the boss 2' is not perpendicular to the mounting surface of the molded product 1' as shown in FIG. 2, the part 3 will hit only one side of the top surface of the boss 2'. For this reason, there was a drawback that sufficient positioning was not possible particularly in the direction of the arrow. Here, 4 is a tapping screw.
本考案はこのように樹脂成形品の取付面に対し
てボスが垂直でない場合に、部品の位置決め精度
の向上をはかろうとするもので、簡単な構成によ
り所期の目的を達成しようとするものである。 The present invention aims to improve the positioning accuracy of parts when the boss is not perpendicular to the mounting surface of the resin molded product, and aims to achieve the intended purpose with a simple configuration. It is.
以下その一実施例を第４図〜第６図とともに説

当接を点接触として、取付寸法精度を得るもので
ある。 An example of this will be described below with reference to FIGS. 4 to 6. As shown in FIG. 4a or b, the present invention has a semi-cylindrical or hemispherical protrusion 6 on the top surface of a plurality of bosses 5 integrally protruding from a resin molded product 1.
Alternatively, 6' may be provided integrally, and the abutment between the component 7 and the boss 5 may be made into a point contact to obtain mounting dimensional accuracy.

部品７をボス５に固定する。この状態を第５図に
示す。 In each of the examples shown in FIGS. 4a and 4b, two protrusions 6 or 6' are provided on the top surface of the boss 5 adjacent to the screw hole 8.
In this case, the two protrusions are arranged on a line that is perpendicular to the line connecting the two bosses 5. The component 7 is brought into contact with the tips of the protrusions 6 and 6', and the component 7 is fixed to the boss 5 with a tapping screw 9. This state is shown in FIG.
したがつて、かかる構成によれば、成形ボス５

らず、部品３をその取付方向に対して十分な位置
決めをして取付けることができる。 Therefore, according to this configuration, the molded boss 5
Even though the angle is not perpendicular to the mounting surface of the resin molded product 1, the component 3 can be mounted with sufficient positioning in the mounting direction.

る。 As described above, according to the present invention, two protrusions are integrally provided on the top surface of the molded boss so as to be adjacent to the screw hole, and these two protrusions are aligned with the line connecting the two molded bosses. By arranging the part and the molded boss on a line that is perpendicular to the molded part, the contact between the part and the molded boss can be made into a point contact through the above-mentioned protrusion. Nevertheless, the parts can be mounted on the mounting surface with high precision, and its practical value is extremely great.
