ABSTRACT:
A rotary connector includes a stationary case fixed to a stationary member, a rotating case combined with the stationary case for rotation relative to the stationary case, and the rotating case having a torque transmission section for transmitting a torque from a rotating member and a junction to be connected to an external wire. A flexible flat cable having a plurality of electrical conductors coated for insulation is housed, in the form of a spiral capable of tightening and loosening, in an annular space defined by the two cases, one end of the flat cable being connected at the junction to the external wire. The torque transmission section and the junction are fractured and removed from the rotating case under first and second torques, respectively, transmitted from the rotating member.
