Abstract: An impeller includes a backing plate, a rim disposed so as to face the backing plate, and a plurality of blades arranged in a circumferential direction around a virtual rotation axis of the backing plate. Each of the plurality of blades has an inner circumferential end, an outer circumferential end a sirocco blade portion being forward-swept and including the outer circumferential end and having a blade outlet angle of larger than 90 degrees, and a turbo blade portion being swept-back and including the inner circumferential end, a first region located closer to the backing plate than a middle point in an axial direction of the rotation axis, and a second region located closer to the rim than the first region. Each of the plurality of blades is formed such that a blade length in the first region is longer than a blade length in the second region. In the first region and the second region, a ratio of the turbo blade portion in the radial direction is larger than a ratio of the sirocco blade portion in the radial direction.

Abstract: A blower includes a fan that causes momentum to air by rotation, a shaft that defines a rotation axis of the fan, a bearing that supports the shaft outside of the fan, and a weight that is movable in a direction of rotation of the fan. In the fan, the weight is located opposite to the bearing with respect to an end of the fan adjacent to the bearing, and thus an increase in weight by the weight can be reduced.
