Abstract
A flexible drive cable for use in motor vehicles, comprising an elongated torque-transmitting core member; an elongated tubular liner member, make of plastic material, defining an internal passage adapted to receive and movably support the core member; and an elongated tubular outer member for holding therein the liner member; at least one caved portion or cavity being disposed between the exterior of the liner member and the interior of the outer member. The caved portion or cavity can sufficiently prevent the noise which is produced upon engagement of the rotating core member against the interior face of the liner member, from being propagated outside through the outer member, and thereby can provide a flexible drive cable which exhibits a minimum amount of noise upon operation.
