ABSTRACT:
In an automotive manual transmission including a control rod which, for establishing a speed change of the transmission, is rotated about its axis and then moved along the axis, there is proposed an arrangement which comprises an arm secured to the control rod, a hollow holder secured to the transmission housing and having at its side wall section a through hole, a piston axially movably received in the holder and having at its side section a recess which opens to the through hole of the holder, the piston being contactable with the top of the arm when the arm is rotated with the control rod by a predetermined degree in a direction toward the piston, a spring for biasing the piston toward the top of the arm so that upon contact of the piston with the top of the arm, the arm and thus the control rod are biased to rotate about the axis of the control rod in a direction away from the piston, a detent ball slidably received in the through hole of the holder with a portion thereof projected into the recess of the piston, and a biasing unit for biasing the detent ball toward the bottom of the recess.
