PURPOSE: To simplify the tests of properties and durability by connecting the linkage member, of which change levers shifting and selecting operations are in separate rectilineal motions, and the output member of the actuator which is mounted on outside the body with the push-pull cable.

CONSTITUTION: The change gear lever 2 for manual transmitting operation is mounted near the upper end of the control rod 4, and shifting and selecting operations of the lever 2 are separately transmitted to the transmission 3, the former as revolving motion of the control rod 4 around the center axis and the latter as rectilineal motion in the axial direction. The actuator 12 for shifting and the actuator 13 for selecting are linked with the rods 6, 10, through the push-pull cables 17, 18, which rectilineally displaces, among the ring members following the control rod 4 of the transmission 3 to consistitute the transmitting operation device of chassis-dynamo of the motorcar with the cloumn-shift type manual transmission.
