Abstract
A stiffening structure for an automotive door panel part according to the present invention includes a door outer panel 3 made of a metal sheet curved along a height direction, and in which a character line 3a is formed; and an impact beam 5 disposed at an inner surface side of the door outer panel 3. The stiffening structure improves tensile rigidity of the door outer panel 3 by attaching a stiffening member 7 made of resin to the inner surface of the door outer panel 3. The stiffening member 7 includes vertical bone portions 9 extending in a streak shape from the impact beam 5 to the character line 3a along a curve of the door outer panel 3. The vertical bone portions 9 are arranged at a predetermined interval in a front-rear direction of the door outer panel 3, and outer surface of the vertical bone portions 9 is bonded to the inner surface of the door outer panel 3.
