したことを特徴とするエンジンのデコンプ装置。 (2) 上記リリースレバーに設けられたフライウ
エイトの遠心力に対向上押圧するリターンスプリ
ングを設けたことを特徴とする請求項(1)記載の
エンジンのデコンプ装置。[Scope of Claim for Utility Model Registration] (1) In a decompression device that opens an intake valve or an exhaust valve via a tapepet using a release lever with a flyweight to reduce compression pressure in a combustion chamber when the engine is started, A tapepet pushing up cam in the shape of a cam ridge is formed at the end facing the lower surface of the tappet. A decompression device for an engine, characterized in that a cutout is formed in a part of the cam so as to reduce the cam. (2) The engine decompression device according to claim (1), further comprising a return spring that presses against the centrifugal force of a flyweight provided on the release lever.
