Abstract:
An electrical connecting device between a steering wheel and a steering column for a vehicle, the steering column having an interior and an exterior, the device comprising:a housing fixed on the interior of the steering column;a rotor rotatably arranged in the housing so as to define an annular cable accommodating chamber having an inner peripheral face and an outer peripheral face, wherein the accommodating chamber is located between the rotor and the housing, the rotor constituting the inner peripheral face of the cable accommodating chamber while at least the housing constitutes the outer peripheral face and the upper face of the cable accommodating chamber;a flexible flat cable accommodated in the cable accommodating chamber, the flexible flat cable having one end fixed on the rotor and the other end fixed on the housing, the one end of the flexible cable being wound along the inner peripheral face in one winding direction and the other end of the flexible flat cable being wound along the outer peripheral face in an opposite winding direction in a manner that the winding direction of the flexible flat cable is reversed to the opposite winding direction of the flexible flat cable on a boundary of a turn-over part of the flexible flat cable;an inside projection formed on an upper face defining the cable accommodating chamber so as to project downward in a projection direction on an inner peripheral side of the cable accommodating chamber; andan outside projection formed on an upper face defining the cable accommodating chamber so as to project downward in a projection direction on an outer peripheral side of the cable accommodating chamber;wherein an amount of projection in the protection direction of the inside projection is smaller than an amount of projection in the projection direction of the outside projection.
