Abstract
An inner wheel element () is embedded in an outer wheel element (), such that a continuous range from an inner diameter side circumferential surface configuring an inner surface of a first annular concave part (), through an outer circumferential surface of the inner wheel element (), to an inner diameter side circumferential surface configuring an inner surface of a second annular concave part () in a surface of the inner wheel element () is covered over the entire circumference. Accordingly, a structure is achieved which easily secures a holding power of the synthetic resin outer wheel element with respect to the inner wheel element.
