A push-pull cable arrangement for selectively transmitting longitudinal motion to two separate destinations has an inner wire having a front end, a rear end and an intermediate node between the front and the rear ends. The inner wire is enclosed with a first outer casing between the front end and the intermediate node, and with a second outer casing between the intermediate node and the rear end. Front and rear ends of the first outer casing are held stationary. A front end of the second outer casing facing the intermediate node of the inner wire is movable, and a rear end of the second outer casing facing the rear end of the inner wire is held stationary. When the front end of the inner wire is pulled, a longitudinal motion of the inner wire is transmitted to the rear end of the inner wire, by which a first receiving unit is moved. When the front end of the inner wire is pushed, the intermediate node of the inner wire pushes the front end of the second outer casing, by which a second receiving unit is moved. |
