Claims

[Scope of utility model registration request]

A connecting hole that engages with a bar-shaped protrusion provided approximately radially on the outer peripheral surface of the rotating shaft of the power distributor, and a connecting protrusion that engages with a concave groove provided approximately radially on the end i of the camshaft of the engine, parallel to the In the coupling between the rotating shaft and the camshaft, the curve ring is formed by bending a single plate having a spring property almost symmetrically around the connecting protrusion forming portion. An internal combustion engine ignition device characterized in that the connection hole is provided in a portion where the end portions of the plate material overlap and become double.
