Abstract
An electrical connecting device includes a rotor, a stator having a cover and an under cover, a flexible flat cable wound in a spiral manner and accommodated in an annular space defined between the stator and the rotor, and a locking structure for locking the cover to the under cover. The locking structure includes a plurality of engagement projections formed on the outer periphery of the under cover and a plurality of engagement recess formed on the inner periphery of the cover for engagement with the engagement projections. Since the engagement recesses are arranged on the inner periphery of the cover, the engagement projections under its engagement condition with the engagement recess do not project from the outer peripheral surface of the cover. Therefore, it is possible to avoid undesirable unlocking and breaking of the rocking structure in transporting the device.
