  • Fan shroud integral with reserve tank of engine cooling apparatus
    Patent number: 6041744
    Abstract: A reserve tank has a tank body integrally formed with a fan shroud with an opening portion and a cover member for covering the opening portion of the tank body. The inside of the tank body is shaped such that a molding die for forming the inside of the tank body can be removed through the opening portion when the tank body is integrally formed with the fan shroud by an injection molding method. The tank body has a concave part around the opening portion and the cover member has a projection for fitting into the concave part to provide a sealing structure. Accordingly, the reserve tank is integrated with the fan shroud without deteriorating moldability and with sealing reliability.
