されねばならない。PRIOR ART Ignition distributor shielding is provided only when the vehicle ground and the shielding cover are perfectly conductively coupled. In the ignition distributor thus constructed, each contact ring is a molded body having a large bending rigidity and provided with a sleeve-like collar, and the sleeve-like collar is supported on the end faces of the adjacent fixed bushes of the cap. . As a result, the area of the shield cover adjacent to the contact ring must be elastic enough to compensate for manufacturing errors in the parts to be screwed together. Furthermore, this contact ring must be inserted into the shield cover in the correct position in the production tool.

くなる。EFFECTS OF THE INVENTION When a shielded ignition distributor for an internal combustion engine is constructed as in the present invention, the above-mentioned problems in the prior art are largely solved by simple technical means. A spring disc manufactured from a spring metal sheet by stamping does not require increased costs in terms of material and, due to its elasticity, can compensate the manufacturing errors of the parts screwed together. . In addition to this, the present invention also eliminates the need to carefully insert the spring disc into the proper position of the shield cover forming tool.

きる。Embodiments Advantageous embodiments of the invention are described in the second and subsequent claims. For example, when the spring disc is configured as described in claim 2, the elasticity of the spring disc is significantly increased. When the head screw is tightly tightened, the internal teeth are pressed against the end face of the fixed bush in the direction of the screw axis, which may cause loosening of the integrally formed outer part of the spring disc. Looseness can be avoided by the configuration described in claim 3.
実施例 次に図面につき本発明の実施例を説明する。Embodiment Next, an embodiment of the present invention will be described with reference to the drawings.
