1. A vehicle wheel element structure to be fastened to a hub unit of a vehicle, an inner side and an outer side of the vehicle wheel element structure being defined with respect to a vehicle width direction, the vehicle wheel element structure comprising:
a center disc member from which disc members extend radially in an outer diameter direction, the center disc member comprising a center bore and fastening holes;
abutment members that are provided on an inner side of the center disc member, each of the abutment members protruding from a position that is away from an opening of a corresponding one of the fastening holes by a predetermined distance, the each of the abutment members protruding by a predetermined amount with respect to a reference plane when the abutment member is fastened to the hub unit, the abutment members being configured to abut first on a hub-side fastening surface; and
wheel-element-side fastening surfaces that are provided on the inner side of the center disc member, each of the wheel-element-side fastening surfaces comprising the openings, the each of the wheel-element-side fastening surfaces being configured to come into surface contact with the hub-side fastening surface on the reference plane when a fastened member that is inserted into the corresponding one of the fastening holes and a fastening member are fastened to each other at a predetermined fastening torque, wherein
the each of the wheel-element-side fastening surfaces is a tapered surface comprising a rough surface having a predetermined depth, the tapered surface having a predetermined angle,
the depth is identical to a protrusion amount of a respective one of the abutment members from the reference plane, and
the each of the abutment members is an edge of a corresponding one of the wheel-element-side fastening surfaces.
