a clock spring used with , e . g ., a steering apparatus of a motor vehicle to establish electrical connection between a stationary member and a movable member by using cables . the clock spring has a stationary member , a movable member fitted to the stationary member so as to be rotatable relative to the same , and a cable having a portion accommodated in a cable housing defined by the stationary and movable members . two end portions of the cable are respectively fixed to the stationary and movable members and are led out of the cable housing . an improvement achieved by the invention resides in that the portion of the cable accommodated in the cable housing consists of a portion coiled on the stationary member , a portion coiled on the movable member in the direction opposite to the direction of coiling in the stationary member , and a turned portion connecting the coiled portions , and that a rolling member is provided which is pinched between the stationary and movable members and which serves as an indicator .
