ABSTRACT:
A rotary connector device in which a flexible cable is maintained in parallel with the wall of a housing even if the supporting member is deformed, thereby reducing noise from the flexible cable and deterioration of the durability of the cable. Projections, which are crushed upon assemblage, are provided for absorbing an assemblage tolerance. The flexible cable is received spirally within the space formed between a rotor housing and a stator housing. A terminal is electrically connected to conductive wires exposed from the flexible cable and formed with the supporting member in a body. The supporting member has a connector section and a cable connecting section supported by the connector section as a cantilever. The cable connecting section is connected to each of the housings, and the connector section is connected to the cable connecting section through a predetermined gap. Projections are also provided on an offset of the inner surface of the rotor housing for absorbing the assemblage tolerance in a circular direction and an axial direction simultaneously. These projections are crushed upon assembling the rotor housing with the attachment.
