A four-wheeled buggy includes a shortened air intake path so that intake efficiency is improved. An air cleaner is disposed in a space surrounded on the left and right by a rear fender below a seat, and a space surrounded by the air cleaner, the seat and left and right portions of the rear fender is formed as an intake air path. A cutaway portion is provided on a side face of the rear fender connecting to a seat rail and is formed as an intake opening communicating outwardly sidewardly such that it is communicated with the intake air path on the inner side. External air taken in from the intake opening enters the intake path and is immediately introduced into the inside of the air cleaner through an intake duct.
