<p>PURPOSE:To shorten the length of a needed cable while to prevent the reversal part of the cable from buckling. CONSTITUTION:A flexible cable 32 is wound around the outer tube part 35 and the inner tube part 36 in mutually reverse directions via a reversal part 32a while the reversal part 32a positioned in a turning neutral position is set so as to be apart from a first connector 39 for the purpose of leading out the flexible cable 32 to the exterior of the outer tube part 35.</p> |
