The connecting pipeis made of an elastic material having rubber elasticity, and has a connecting partconnected to the intake silencer, an inner tubular partextending from the connecting partinto the expansion chamberand having the inlet, and an outer tubular partconnecting to a throttle device. The wallof the inner tubular partis provided with a communication openingfor connecting the expansion chamberand the air passageto make the expansion chamberserve also as a resonance chamber. The outer tubular partof the connecting pipeis shorter than the inner tubular partof the same. The intake silencer is compact and has a combined effect of expansion silencing and resonance silencing.
