Abstract

PURPOSE: To improve the sound-proof effect of an internal combustion engine in case of providing it with auxiliary machinery, by fitting a cover of the machinery through an elastic member and an internal member fixed in the elastic body.
CONSTITUTION: An ignition device composed of an igniter 8 and a cam projection 9 for controlling the igniter 8 is externally applied to a crankcase 2 of a power unit 1 and covered with an igniter cover 3. An elastic packing 4 is put between the crankcase 2 and the cover 3, and an internal member 7, covering the ignition device and its end 7b being inserted in the elastic body 4, is also applied to absorb the noise of the power unit 1 through the cover 3.
