In a power transmission mechanism, a line connecting a center shaftof a reference gear memberand a first shaftof a first planetary gear memberand a line connecting the center shaftof the reference gear memberand a second shaftof a second planetary gear memberform a specific angle α. Rotation in one direction is prevented when a first carrier memberand a second carrier memberare relatively rotated in a direction to decrease the specific angle α. Further, a rotation prevention release unit is provided to release a prevention state of the rotation when the first carrier memberand the second carrier memberare relatively rotated in a direction to increase the specific angle α.
