<p>PURPOSE:To make it possible to electrically connect relative rotating bodies without using rubbing contact points by attaching electric cables to two machine bodies relatively rotating mutually and concentrically, by winding cables in a spiral form between both the machine bodies for giving the habit of spiral and by extending a supporting bar in the shaft center of both the machine bodies and within the spiral. CONSTITUTION:If a first machine body 3 relatively rotates with respect to a second machine body, an electric cable 48 having the habit of being spiral is accordingly induced and rotated in a turn direction of spiral or in a reverse direction around the supporting bar 56, after making a certain turn, the first machine body 1 rotates reversely with respect to the second machine body, and the electric cable 48 rotates reversely. As stated above, the electric cable 48 is induced and rotated in a winding direction of the spiral or its reverse direction accompanied with the relative rotation of the first and second machine bodies 3 and 1, or reverse rotation occurs so that no twisting of the electric cable 48 occurs. By doing this, the relative rotating bodies can be mutually connected electrically in a state where the occurrence of noise is avoided.</p> |
