PROBLEM TO BE SOLVED: To easily separate double fan shrouds. SOLUTION: A slit 20 is formed between peripheral edges of two shroud portions 11, 12 opposite to each other, and a bridge 30 having weak portions at plural positions along the slit is integrally molded with the shroud portions to form double shrouds. Even when attached to a heat exchanger on a vehicle, the bridge portion 30 is pinched by a tool such as a pair of pliers as necessary, the weak portions are broken and the shrouds are easily separated from each other. Then, the fan shrouds are exchanged without removing a radiator hose and the like. One mold is all that is required, so that part items, a molding cost, and assembling man-hours are reduced.
