Abstract
A method for manufacturing a resin vehicle part provided with a panel body having a decorative surface on the front surface and a stepped reinforcing rib, which stands on the back surface of the panel body and the thickness of the base end of which is formed to be thinner than the thickness of the leading end. On the injection molding die thereof, a sliding piece for forming the stepped reinforcing rib is provided so as to be movable. During shrinkage movement of the stepped reinforcing rib in the height direction after molten resin has been filled in the injection molding die, the sliding piece is pressed by the leading end of the stepped reinforcing rib and moves towards the panel body.
