A resonator structure of a saddle-ride type vehicle includes: a head box 20 that includes a head pipe 21 forming a handlebar steering axis C1 and forms an intake passage 20s through which air is taken from a front of the vehicle into an inside of the vehicle when the vehicle is travelling; an air cleaner box 40 that is connected to the head box 20 and allows the air to be taken into a power unit 10 of the vehicle; and a resonator 23 that forms a resonator chamber 23s configured to reduce an intake noise, wherein the resonator chamber 23s is formed inside the head box 20 in such a way as to continue to the intake passage 20s. The resonator chamber is for reducing intake noise, and the resonator structure achieves size reduction of a front portion of a vehicle body while enhancing a silencing effect of the resonator.
