To provide a manipulator synchronization control device capable of preventing the generation of queue due to interlock and simply setting up the interlock in the case of synchronously controlling manipultors for plural machines.

An operation control command is outputted from a controller 10 to plural manipulators and drive commands for axis driving motors are outputted from plural amplifiers in accordance with the operation control command. At the time of receiving the operation control command for simultaneously driving plural driving axes corresponding to respective manipulators from the controller 10, a machine selector 12 collectively sends the operation control command to a specific amplifier and an axis selector 14 receives the drive command outputted from the specific amplifier and sends driving currents to driving axis motors corresponding to respective manipulators.
