A motorcycle includes a fuel tank that stores fuel, a fuel filling joint hydraulically connected to the fuel tank, a first pressure reducing valve hydraulically connected to the fuel tank to reduce pressure of the fuel to first pressure, a second pressure reducing valve hydraulically connected to the first pressure reducing valve to reduce the pressure of the fuel to second pressure, a fuel cell unit hydraulically connected to the second pressure reducing valve to generate electric power via reaction of the fuel and an oxidizing agent, a high-pressure side structure that supports the fuel tank, the joint, and the first pressure reducing valve while keeping relative arrangement thereof, a low-pressure side structure that supports the second pressure reducing valve and the fuel cell unit while keeping relative arrangement thereof, and a main structure that detachably fixes the high-pressure side structure and the low-pressure side structure.
