Abstract: A mounting structure for a vehicular resin component provided with a panel body having a design surface on a surface of the panel body; a reinforcement rib arranged upright on a back surface of the panel body; and a mounting member for a vehicle. The reinforcement rib includes a proximal end portion connected to the panel body and formed with a thickness thinner than a thickness of a distal end portion. The distal end portion of the reinforcement rib includes an inclined surface formed between the distal end portion and the proximal end portion with increasing thickness toward the leading end side, and is provided with a locking hole with a hole direction inclined in the direction of inclination of the inclined surface. In the mounting member, a locking claw capable of being fitted in the locking hole is formed.

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.

Abstract: A resin part for a vehicle provided with: a panel body having a design surface; and stepped reinforcing ribs, which are vertically arranged on the inside surface of the panel body, in which the wall thickness of the base end portion is formed to be thinner than the wall thickness of the leading end portion, and in which the side ends at the end in the direction in which the ribs extend (arrow (X) direction) are open. Resin supply ports, to which molten resin is supplied prior to the base end portion, are formed in the leading end portion.
