Claims

[Scope of utility model registration request]

a shroud 2 which is formed to widen toward the front end and whose front end edge is attached to the outer periphery of the radiator core 1; a boss portion 3 which is located on the axis of the shroud 2 and whose outer periphery forms part of a conical surface; A plurality of wing parts 4 are integrally formed on the outer circumferential surface of the boss part 3 with one end edge being spaced apart from each other, and a plurality of wing parts 4 are formed concentrically with the boss part 3 on the outside of the boss part 3, and each of the wing parts 4, the other end edge of the shroud 2 is integrally formed with the inner circumferential surface of the shroud 2, and the front end edge is located close to the rear end edge of the shroud 2. The projection planes of the respective wing parts 4 viewed from the axial direction are arranged so as not to overlap with each other, and the outer cylinder part 5 has the same axis-perpendicular cross section of each part, or has a slight cross section toward the front end. A mixed flow fan for a radiator, characterized in that the boss part 3, the wing part 4, and the outer cylinder part 5 are integrally molded of synthetic resin.
