[Solution] When viewed from the upstream side in an air flow direction, a filter (35) is divided by an imaginary division line (DL), which crosses peripheral edges of the filter, into two areas (for example, two oblong areas), which are a first area (35A) and a second area (35B), and a separation cylinder (14; 14B) or an air intake housing (21; 21A; 21B) is configured such that an opening area (240) surrounded by peripheral edges (241, 242, 243, 244) of the inlet-side end (24) of the separation cylinder (14; 14B) coincides with the first area (35A).
