A connector device includes a fixed housing fixed on a fixed member, a movable housing mounted on a rotatable member and freely rotatably combined With the fixed housing, and a flexible flat transmission line which serves to electrically or optically connect the fixed member to the rotatable member, which is wound in a spiral form and which is received in a space created by the a fixed and movable housings. A clearance in an axial direction along the rotation shaft of the movable housing between the flat transmission line and the movable housing, or between the flat transmission line and the fixed housing is set to be smaller in the intermediate portion of the flat transmission line than in at least one of the end portions at which the flat transmission line is fixed on the housings so as to suppress occurrence of unpleasant vibration sound caused by collision between the flan transmission line and the housings.
