Conventionally, as shown in FIGS. 2 and 3, a pilot hole or screw hole 51 for self-tapping has been provided in the center.
A structure has been proposed in which a guide 52 having a horizontal arc-shaped cross section around the pilot hole or screw hole 51 and protruding upward is integrally formed on the outer periphery of a round boss 50 formed by boring a hole. ing. With such a boss 50, the position of the pilot hole or screw hole 51 can be automatically determined by arranging the assembly parts along the guide 52, so it is possible to mass produce molded products using synthetic resin materials. This has made it possible to automate the assembly work, and has contributed to improved productivity, especially in sanitary cleaning equipment, etc., in which a large number of assembly parts are arranged and fixed in a small casing.

However, in the conventional boss structure described above, since the wall thickness of the part where the guide 52 is provided and the other parts are different, the cooling solidification strength of the synthetic resin during molding is different between the thick part 53 and the thin part 54. Thick part 5
3 takes a longer time to harden than the thin wall portion 54, so that a sink mark 55 is generated on the inner surface of the prepared hole of the thick wall portion 53 or the screw hole 51. As a result, the effective area of the spiral in the pilot hole or screw hole 51 decreases, making it impossible to obtain a normal spiral tightening force, and causing loosening of the screw member or even loosening of the screw member, which may cause the assembled parts to rattle or fall off. It was becoming.

The structure of the component assembly boss having the above configuration is such that a plurality of guide pieces are arranged in an arc shape at appropriate intervals around the pilot hole or screw hole, and the thick wall part created by integrally molding the guide pieces This eliminates concentration of water and equalizes the difference in cooling rate during molding. Furthermore, by forming the width of the guide piece around the pilot hole or screw hole to be approximately the same as the wall thickness of the round boss itself, the influence of the cooling solidification rate caused by the difference in wall thickness caused by the guide piece is eliminated. .

である。 In Fig. 1, numeral 1 is a round boss for fixing assembly parts that is integrally molded on a molded product 2 made of synthetic resin such as a casing of a sanitary washing device, and has a self-touch opening upward in its center. Pin screws and other fixing screw members (not shown)
A pilot hole or screw hole 3 is provided for insertion of the screw. A plurality of guide pieces 4 arranged in an arc shape at appropriate intervals c are integrally molded within a predetermined range of the outer peripheral member of the round boss 1 around the pilot hole or screw hole 3 of the round boss 1, and the lower end thereof are projected onto the upper edge of the round boss 1, respectively. These guide pieces 4 are used to regulate the position of corners, etc. of the assembled part when placing the assembled part on the round boss 1, and facilitate the positioning of the assembled part with respect to the casing, etc. be.
In addition, these guide pieces 4 have a width t 2 around the pilot hole or screw hole 3 of the round boss 1.
The thickness of the guide piece 4 is approximately equal to the thickness t 1 (t 1 = t 2 ) of the guide piece 4, and the thick portion is dispersed by the guide piece 4.
The cooling and solidifying action during molding should be performed evenly. Reference numeral 6 denotes an inclined portion formed on the inner periphery of the upper end of each guide piece 4 to facilitate the assembly work of the parts to be assembled. This inclined portion 6 allows the parts to be assembled to be automatically guided to their normal positions even if they are slightly misaligned, thereby making it possible to automate the assembly work.
