PROBLEM TO BE SOLVED: To provide a wheel cover excellent in apparent quality and mechanical properties with low protrusion at the welded places. SOLUTION: This wheel cover to be mounted to a wheel of a car is produced by molding a composition containing 20-67wt.% of a polypropylene resin, 3-30wt.% of a thermoplastic elastomer and 30-50wt.% of acicular calcium silicate. This acicular calcium silicate preferably has <100 of filler orientation index and an average particle size of 1-1,000μm. This polypropylene resin contains 3-12wt.% of the ethylene component and is a high-crystalline block polypropylene resin with a heat distortion temperature of >=125 deg.C (455kPa) and the melt flow index of >=30g/10min.
