The impeller includes a hub that is disposed on an end portion of the shaft member, and a plurality of blades disposed on an outer peripheral surface of the hub. The impeller has a shape that tapers outward in the axial direction. A cover member is disposed at least at an end portion of the impeller outside in the axial direction. The cover member is joined to outer peripheries of the plurality of blades in a radial direction and covers at least a part of the plurality of blades from outside in the radial direction. A first bearing is disposed outside in the radial direction of the cover member, the first rotatably supporting the impeller.
