The present invention provides a filter element in which the folds at one end are separated by a chevron-shaped wall and the creases at the other end are closed. Or they are arranged so that they abut, and one end of the filter element is the inlet side of the intake air, so that the intake air flows in between the widely separated pleats and flows out to the inner circumferential surface and lower end of the filter element. Therefore, there is no need to form an annular chamber for introducing intake air between the case and the outer periphery of the filter element, and as a result, the filter element can be miniaturized without causing flow resistance.
