A panel driving device turns an openable panel inside out by rotating the openable panel by 180.degree. about a rotation center shaft and moving the rotation center shaft upward or downward during a specific period while the openable panel is rotated. The panel driving device is provided with a rotating mechanism for supporting the openable panel on a rotatable end of a rotary arm and rotating the openable panel, and a torque converting mechanism for converting part of a driving force of the rotating mechanism into a rotating force for rotating the rotary arm only during the specific period to rotate the rotary arm upward or downward. The openable panel can be turned inside out by a simple construction.
