<p><P>PROBLEM TO BE SOLVED: To accommodate extra length of a wiring harness certainly when the extra length of the wiring harness changes by a rotational angle of a link. <P>SOLUTION: In this structure, a cradle 4 supports a first link 1 by an axis part 5 rotatably, a second link 2 is connected to the first link rotatably, a wiring harness 6 is arranged along the both links, and the wiring harness is fixed to the cradle and the second link. A cam member 7 is provided to the first link on the side of the axis part. The cam member has a profiled part 9 in which a distance from the center of the axis part to the cam surface 9a is gradually increased, and extra length of the wiring harness generated when the first link rotates is accommodated by the profiled part. The wiring harness is fixed at the position of approximately the same height as that of the axis part on the cradle side, and the wiring harness is arranged linearly along the cradle 4 from the first link 1. A fixing clamp 11 on the cradle side and a harness guide pipe 15 on the side of the first link are arranged on the same vertical surface. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
