Claims

[Scope of utility model registration request]

A plurality of mounting legs protrude from the back surface of the wheel cover body at predetermined intervals along the circumferential direction and engage with the wheel, and an annular holder ring formed on a surface of the mounting legs facing toward the center of the wheel cover body. In the mold structure of a resin wheel cover having a ring groove for attaching the wheel cover, a protrusion forming the ring groove is formed on the core mold forming the back side of the wheel cover body, and the protrusion forming the ring groove is aligned with the circumference of the wheel cover in correspondence with the mounting leg. A plurality of rotary core molds protruding in a plurality of directions are rotatably provided, and a notch is provided between the circumferentially protruding positions of the adjacent protrusions to form a space slightly longer than the circumferential width of the mounting leg. A wheel cover mold structure characterized by being provided in a rotating core mold.
