In a motorcycle particularly of a scooter-type structure, an intake device is received in a rising portion of a tunnel shaped portion formed to a footrest floors of a motorcycle body, the intake device being provided with a cleaner box including an air cleaner, with a throttle body disposed on a downstream side of the cleaner box and with a surge tank disposed on a downstream side of the throttle body. The throttle body and the surge tank are placed side by side above a cylinder assembly of the engine unit, and the cleaner box is placed above the throttle body and the surge tank. These respective elements are connected by means of pipes so as to provide an S-shape structure in a plan view.
