ABSTRACT:
A clock spring for use with a steering device of an automobile, including a fixed member, a movable member rotatably mounted on the fixed member with a cable accommodating portion defined therebetween, and a cable accommodated in the cable accommodating portion for effecting electrical connection between the fixed member and the movable member. One end of the cable is fixed to the fixed member and led out of the fixed member, while the other end of the cable is fixed to the movable member and led out of the movable member. One portion of the cable is wrapped in one direction on either of the fixed member or the movable member, while the other portion is wrapped in the opposite direction reverse to the one direction on the other of the fixed member and the movable member, whereby an inverted portion of the cable is formed between the one portion and the other portion. The improvement of the clock spring resides in the point that the number of wrapping of one or several of plural cable elements constituting the cable is set to be smaller than that of the remaining cable elements.
