て直角に入らないなどという問題点を有していた。The conventional resin-molded boss fabric constructed as described above will be described below with reference to the drawings. - This type of resin-molded boss structure that has been used in the past has been used to fasten a barbed member 13 to a boss 1.1 attached to a resin chassis or the like using a fastening component 13. , Problems to be Solved by the Invention Therefore, in the conventional structure described above, if the diameter of the boss 11 is increased, there will be sink marks, deformation, etc. It is decided,
There were limits to reinforcement. Therefore, when fastening the mounting member 12 with the fastening component 13, the boss 11 is
The mounting member 12 cannot be stably attached because cracks occur due to stress being applied to the base of the mounting member 12 or because the contact area between the mounting member 12 and the boss 11 is small. Also, boss 11
Since the strength of the fastening part 13 is weak, there is a problem that the fastening part 13 does not enter the boss 11 at right angles.
本発明は、上記の従来の問題点を解決するもので、強く
取付性の良い樹脂成形ボス構造を提供するものである。The present invention solves the above-mentioned conventional problems and provides a resin-molded boss structure that is strong and easy to install.
問題点を解決するだめの手段
上記の問題点を解決するために本発明のボス構造は、従
来の円筒型ボスの周囲にリム状のリブを配置するという
構成を備えたものである。Means for Solving the Problems In order to solve the above problems, the boss structure of the present invention has a configuration in which a rim-shaped rib is arranged around a conventional cylindrical boss.
作 用
本発明は、上記した構成によって、強靭で取付性の極め
て良い樹脂成形ボス構造にすることができる。Effects The present invention can provide a resin-molded boss structure that is strong and has extremely good attachability due to the above-described configuration.
実施例
以下本発明の一実施例のボス構造について、図面を参照
にしながら説明する。EXAMPLE Hereinafter, a boss structure according to an example of the present invention will be described with reference to the drawings.

ある。In FIG. 1, 11 is a boss having a cylindrical boss 11a, a hollow cylindrical rib 11b arranged around the boss 11a, and a radial shape 110 connecting the boss 11a and the cylindrical rib 11b.
以上の様に構成されたボスについて、第１図。FIG. 1 shows the boss configured as described above.
第２図を用いてその特徴を説明する。Its characteristics will be explained using FIG.

ブ１１ｂに伝わり、単位体積当りの応力が少なくなる。First, FIG. 1 is a perspective view showing a tree molded boss structure according to an embodiment of the present invention, and FIG. 2 is a sectional view thereof. When the mounting member 12 is fastened to the boss 11 with the fastening part 13, when the fastening part 13 enters the cylindrical boss 11a, the force applied to the root of the cylindrical boss 11a due to the torque is transmitted through the radial rib 11C, This is transmitted to the hollow cylindrical rib 11b, and the stress per unit volume is reduced.

ことができる。As described above, according to this embodiment, the hollow cylindrical ribs arranged around the cylindrical boss 11a and the radial ribs connecting the cylindrical boss 11a and the hollow cylindrical ribs 11b provide
It is possible to prevent deformation of the boss 11 and cracks at the base due to the force applied when the mounting member 12 is fastened with the fastening component 13.
