<p>Fan unit installation projections (41, 52A) extend substantially parallel to the rotating shaft of a fan (11) of a fan unit (1, 1A) and are provided integrally with a fan unit installation section. A belt-like elastic body (3, 3A-3F) is passed over the fan unit installation projections (41, 52A). The belt-like elastic body (3, 3A-3F) is made to be in contact with multiple portions of the outer periphery (12a) of the fan unit, so that the fan unit is held by holding force of the belt-like elastic body with a gap retained between the fan unit and the fan unit installation section.</p> |
