CONSTITUTION: There are arranged rotating shafts 2 and 5 to transmit the rotation of a motor to a head part and the rotating shafts are linked through link members 10 and 20. At a link part, an insulated joint member 10 is formed on the side of the shaft end of the rotating shaft 2, a claw member 20 made of a metal to be connected to the joint member 10 and a claw part 20a at the tip of the claw member 20. The claw part 20 is engaged with a claw part 5a of the rotating shaft 5 on the side of a head. Thus, the rotating shafts 2 and 5 are insulated electrically by the insulated joint member 10 and engaged with each other through the claw parts 20a and 5a made of a metal.
