A transportation vehicle part includes: a patch member 13 constructed of a plate-like metal patch panel 12, and a vibration attenuating resin layer 14 provided along a surface of the patch panel 12; and a metal base plate 16 closely adhered with the vibration attenuating resin layer 14 of the patch member 13 and affixed with the patch member 13. The patch panel 12 is produced via a rolling step. An acute angle between a longitudinal direction and a rolling direction of the patch panel 12 is 30 to 70 degrees. According to this structure, the natural frequency in a primary mode is made high, whereby the vibration characteristic is improved.
