Each of the laminated portions is composed of an outer vertical wall portion, an inner vertical wall portion, and an intermediate vertical wall portion. A fillet is formed between an outer surface of the intermediate vertical wall portion with respect to an air-passing direction and an inner surface of the outer vertical wall portion with respect to the air-passing direction. Another fillet is formed between an inner surface of the intermediate vertical wall portion with respect to the air-passing direction and an outer surface of the inner vertical wall portion with respect to the air-passing direction.
