Abstract

An exhaust silencer device for an internal combustion engine which includes: an exhaust pipe (10) that forms an exhaust passage from an engine (1), and an exhaust opening; and a muffler (22) attached to the exhaust pipe (10) so as to silence exhaust sound from the engine (1). The piping lengths of the exhaust passages (L2, L3) on two sides of the muffler (22) are substantially equal. At least one of the two exhaust passages (L2, L3) equal in piping length has a hole (41) that makes the resonance frequencies of the two exhaust passages (L2, L3) different from each other.
