<p><P>PROBLEM TO BE SOLVED: To provide an arm power supply structure in which a protector for power supply is made to be compact and a shaft is prevented from being damaged due to an excessive force acting on the arm. <P>SOLUTION: The arm power supply structure includes an arm 5 pivotally supported to freely rotate in a protector 2 consisting of a protector base 3 and a protector cover 4, wherein a wire harness 34 is fixed on the front end of the arm. In this structure, a cylindrical shaft 9 is provided on the base end of the arm 5, a cylindrical bearing 10 engaging with the inside of the shaft 9 is provided on the protector base 3, and a hole 11 for inserting a fixing bolt is provided on the protector base in the inside of the bearing. The arm 5 has flexibility in a plate thickness direction, and when a force of the plate thickness direction acts on the arm, the arm is warped to reduce a load on the shaft 9. The arm 5 is allowed to abut on the protector cover 4 while being warped in the plate thickness direction. A sub-arm 6 provided on the arm 5 is allowed to abut on the protector base 4. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
