  • Publication number: 20090279933
    Abstract: A rotary shaft locking device includes a locking unit having a transmission gear receiving rotary torque from a power source, transmitting rotary torque to a rotary shaft as the transmission gear receives rotary torque from the power source, and locking the rotary shaft as transmission of rotary torque from the power source is cut off, and a first planetary gear and a second planetary gear provided to be meshed with a sun gear and to planetarily move around the sun gear, and displaced between a meshed position and an unmeshed position so as to be meshed with and separated from the transmission gear. The locking unit locks the rotary shaft for a power cutoff time which occurs when the rotation direction of the sun gear is switched and for which the transmission gear is not meshed with both the first planetary gear and the second planetary gear.
