To provide a centrifugal blower which can simplify assembling work while suppressing the number of part items.SOLUTION: A centrifugal blower comprises a centrifugal fan 10, a fan casing 30, a separation cylinder 50 and an inside/outside air casing 41. The inside/outside air casing 41 is an assembly formed by assembling a first inside/outside air division body 41A and a second inside/outside air division body 41B which are divided along an axial direction DRa of a fan axial core CL. The separation cylinder 50 is an assembly formed by assembling a first cylinder division body 50A and a second cylinder division body 50B which are divided in the axial direction DRa. Then, in the separation cylinder 50, the first cylinder division body 50A is constituted as an integrated molding integrated with the first inside/outside air division body 41A, and the second cylinder division body 50B is constituted as an integrated molding integrated with the second inside/outside air division body 41B.SELECTED DRAWING: Figure 7 【課題】部品点数を抑えつつ、組付作業の簡易化を図ることが可能な遠心送風機を提供する。【解決手段】遠心送風機１は、遠心ファン１０と、ファンケーシング３０と、分離筒５０と、内外気ケーシング４１と、を備える。内外気ケーシング４１は、ファン軸心ＣＬの軸方向ＤＲａに沿って分割された第１内外気分割体４１Ａと第２内外気分割体４１Ｂとを相互に組み付けた組付体である。分離筒５０は、軸方向ＤＲａに分割された第１筒分割体５０Ａと第２筒分割体５０Ｂとを相互に組み付けた組付体である。そして、分離筒５０は、第１筒分割体５０Ａが第１内外気分割体４１Ａと一体成形物として構成され、第２筒分割体５０Ｂが第２内外気分割体４１Ｂと一体成形物として構成されている。【選択図】図７
