PURPOSE: To prevent a lead wire from twisting and twining by providing a collar part and a head base which has a lead wire clamping member at a position corresponding to the lead-wire clamping cut of a head rotating support bearing member.
CONSTITUTION: The lead wire 20 wound in the gap between a head rotary plate 4 and the collar part 7b is run through the gap 12h between lead clampers 12f and 12g. Then, when the head rotating support bearing plate 9 is fitted to the head base 12, end surfaces 9d and 9e of the clamping hole 9c on the receiving plate 9 presses slanting surfaces 12i and 12j of the lead wire clampers 12f and 12g inward to narrow down the gap 12h eventually, thereby clamping the lead wire 20. Consequently, the twisting of the lead wire is prevented and even if the lead wire has a slack at a lead-wire winding-up part, the collar part 7b is prevented from moving below the collar part to prevent the lead wire from twining with other members in a head clock.
