In a tank-integrated shroud, a shroud body has an air guiding wall having a first surface along which air flows and a second surface opposite to the first surface. The air guiding wall has a looped projection on the second surface. The looped projection forms a recess therein that is recessed from the first surface of the air guiding wall. A tank has an opening at one side. The periphery of the opening is welded to the looped projection of the shroud body, so the tank is integrated with the shroud body. During welding, a part of a welding jig is inserted into the recess of the looped projection.
