A resonator structure of a saddle-ride vehicle includes a head box that includes a head pipe defining a handlebar steering axis and that forms an intake passage through which air is guided from a front of the vehicle into an inside of the vehicle when the vehicle is traveling, an air cleaner box that is connected to the head box and allows the air guided through the intake passage to be taken into a power unit of the vehicle, and a resonator that forms a resonator chamber configured to reduce an air intake noise. The resonator chamber is formed continuous to the intake passage inside the head box.
