Claims

[Scope of utility model registration request]

(1) One ignition timing setting member attached to a flywheel that rotates in synchronization with the internal combustion engine, and the other ignition timing setting member attached to the crankcase of the internal combustion engine,
When attaching the flywheel to the crankshaft of an internal combustion engine, the proximity positional relationship of both ignition timing setting members should match due to the combustion stroke positional relationship of the crankshaft and the rotation of the flywheel. The internal combustion engine ignition timing setting device mounting structure includes a position alignment means and an internal combustion engine ignition timing setting device mounting structure.

(2) Utility model registration The internal combustion engine ignition timing setting device mounting according to claim 1 has a structure in which the positioning means includes a hole or notch formed in the flywheel, and a hole or notch formed in the flywheel. A recess formed in the crankcase at a position corresponding to the notch, and a jig for inserting into the hole or notch and fitting into the recess to position the flywheel in the crankcase. Internal combustion engine ignition timing setting device installation is structural.

(3) Utility Model Registration The internal combustion engine ignition timing setting device mounting according to claim 2 has a structure in which the positioning means uses a keyway formed in the output shaft of the crankshaft to The internal combustion engine ignition timing device mounting structure further includes a jig to secure the internal combustion engine ignition timing device in place.
