<p>PURPOSE:To absorb axial vibration without increasing the number of components by imparting resiliency to a flat cable CONSTITUTION:A flat cable 68 in a spiral cable unit 14 is bent at the opposite edges in the breadthwise direction thus forming first and second abutting parts 82, 84 at the opposite edges. The first abutting part 82 abuts on the bottom face of a rotor 58 while the second abutting part 84 abuts on the surface of a cover 52. Since resiliency is imparted to the flat cable 68, axial vibration transmitted to the spiral cable unit 14 can be absorbed positively.</p> |
