To make a fan cover compact and improve air blowing efficiency in a blower module.SOLUTION: A blower module includes: a drive shaft; a centrifugal fan (51) which rotates integrally with the drive shaft; and a fan cover (52) which covers the centrifugal fan (51) from the axial outer side of the drive shaft. The fan cover (52) includes a peripheral wall part (64) disposed at the radial outer side relative to the centrifugal fan (51). The peripheral wall part (64) has: a first wall part (75) facing the centrifugal fan (51) from the radial outer side; and a second wall part (70) disposed at the axial inner side of the drive shaft relative to the first wall part (75). The first wall part (75) is disposed at the radial outer side relative to the second wall part (70).SELECTED DRAWING: Figure 5

    【課題】送風装置において、ファンカバーをコンパクトにし、且つ、送風効率を向上する。【解決手段】送風装置は、駆動軸と、駆動軸と一体に回転する遠心ファン(51)と、遠心ファン(51)を駆動軸の軸方向の外側から覆うファンカバー(52)とを備え、ファンカバー(52)が、遠心ファン(51)に対し径方向外側に配置される周壁部(64)を備え、周壁部(64)は、遠心ファン(51)に径方向外側から対向する第1壁部(75)と、前記第1壁部(75)に対し駆動軸の軸方向の内側に配置される第2壁部(70)とを有し、第1壁部(75)は、第2壁部(70)よりも径方向外側に配置される。【選択図】図5
