  • Patent number: 9950459
    Abstract: To provide a vehicle resin part and a vehicle resin part manufacturing method with which raised portions can be formed using slanted slide molds even on opposing molded portions that have a narrow distance between them. In a rail cover, shelf-shaped portions that can be molded using a cavity and a core are formed on opposing side wall portions, and claw portions that can be molded using slanted slide molds are formed projecting from the shelf-shaped portions in the directions of the opposing side wall portions. Additionally, the claw portions are molded by moving, during demolding, the pair of slanted slide molds in the directions of the opposing side wall portions from a molding position and thereafter removing the pair of slanted slide molds in a forward direction.
