A blower device and an outdoor unit for air conditioner.

A fan device comprising: a propeller fan (4) having a plurality of blades (13), (13) in a thick airfoil shape as typified by airfoil wings formed on an outer periphery of a hub (14) which functions as a center rotation; a bell mouth (5) disposed on an outer radial side of the propeller fan (4) for separating a suction area (X) and a blowoff area (Y); and a fan guard (6) disposed on a blowoff side of the propeller fan (4), wherein the bell mouth (5) consists of a circular arc portion suction side (5a) positioned on one side of aspiration, a circular outlet side (5b) positioned on a blowoff side arc, and a cylinder portion (5c) positioned in between the circular outlet side (5b) arc and the circular arc portion suction side (5a), establishing a ratio of H1 / H0 in a range of H1 / H0 = 0, 40-0, 65, where H1 denotes a height deuna portion of an axis directional height of the bell mouth (5) which overlaps an outer peripheral portion (P) of each blade (13), while H0 denotes an axis directional height of the outer peripheral portion (P) of each blade (13).
