Abstract: PURPOSE: An air cleaner for a vehicle is provided to prevent the leakage of oil in an internal combustion engine by restraining the excessive/asymmetric scattering of oil in an air cleaner. CONSTITUTION: An air cleaner includes a cylindrical element case(12), an intake pipe(14) placed tangentially at the upper end of the element case, a filter element(16) located at the center of the element case to form a center point of a swirl of the sucked air flowing in through the intake pipe, an exhaust pipe(18) placed at the upper center of the element case to guide the symmetric flow of exhaust gas in the element case, and an oil cup(20) mounted below the element case. Intake air collides with the entire area of oil in the oil cup while falling. Thereafter, the filter element firstly filters the air. The filtered air is discharged through the exhaust pipe. As the air uniformly collides to the oil while swirling, the scattering of the oil is minimized. According to the exhaust pipe at the center of the case, the air is symmetrically discharged.
