<p>A first fan (13) is disposed in a first air path (17a) and a second fan (14) is disposed in a second air path (18a). A partition wall (19) that divides a casing (17, 18) into the first air path and the second air path has an inclined part (21) that is inclined towards the second fan as the inclined part (21) extends outward in the radial direction. The second fan has a protrusion (20) that protrudes outward in the radial direction to an edge (15) located towards the first fan in the rotational axis direction. The inclined part is provided so as to cover the protrusion across a gap.</p> |
