PURPOSE:To reduce the wiring number between a mainbody side side signal conversion part and rotation base side signal conversion part by using only a serial signal for the signal reciprocating between the main boy side signal conversion part and rotation base side signal conversion part. CONSTITUTION:A rotation base 2 rotatably held on the hand base 1 of a robot, a current transmission means 6 provided between this hand base 1 and rotation base 2, plural chucks 3 provided on the peripheral edge of the rotation base 2, a signal conversion part 13 located at the robot main body side and a signal conversion part 14 located at the rotation base 2 side are provided. In this case, the signal conversion part 13 converts the parallel signal transmitted from a robot control part into a serial signal and the serial signal transmitted from the signal conversion part 14 into the parallel signal. The signal conversion part 14 converts the serial signal transmitted from the signal conversion part 13 into the parallel signal and the parallel signal transmitted from a chuck driving control part 17 into the serial signal. There is the serial signal only between the signal conversion parts 13 and 14.
