<p>Provided is an air blower which provides a design that does not cause the user concern, and with which the fan performance can be improved; also provided is an outdoor unit for an air conditioner equipped with this air blower. When seen from the direction of the rotational axis of a propeller fan (109), the gap (112) between the blade outer circumference (109d) of the propeller fan (109) and a discharge-side cylindrical part (110c) is formed larger than the gap (111) between the blade outer circumference (109d) and an intake-side cylindrical part (110b), and the intake-side cylindrical part (110b) is formed longer in the axial direction (G) than the discharge-side cylindrical part (110c). Furthermore, the radial deformation of the blades (109a) during rotation as well as manufacturing error, assembly error, and deformation due to changes over time are taken into consideration and the size of the gap (111) is set such that even when there is a disturbance during rotation of the propeller fan (109) the blade outer circumference (109d) and the intake-side cylindrical part (110b) do not make contact, and such that the gap (112) is greater than the gap (111) by at least 1.1 times.</p> |
