A resonator structure which locates a resonator in a dead space inside an engine compartment, protects the resonator from vibration, and prevents a change in frequency due to oil mist residue in blow-by gas entering the resonator. In an internal combustion engine which is oriented horizontally in a vehicle engine compartment, an air cleaner outlet hose is provided in and connected to the downstream side of an air cleaner. The air cleaner outlet hose is connected to a throttle body, and the throttle body is connected to one end of a surge tank of an intake manifold, which intake manifold is provided at the rear side of the internal combustion engine. The resonator is located at the rear side of the air cleaner outlet hose, downstream from a bellows section of the air cleaner outlet hose, and also downstream from a breather pipe connecting section.
