The supporting head includes first and second support units individually having support pins arranged in alignment with the axis of rotation and confronting each other across the spindle unit, and bearing members fixed in a housing and supporting the support pins rotatably through bearings. The support pins in the individual support units are so supported in the bearing members that they can move in their own axial direction together with the bearing members when they are released from the fixed states with the spindle unit and when the bearing members are released from the fixed states in the housing.
