ABSTRACT:
A structure for preventing the movement of a vehicle by preventing the movement of the gear shift rod. A locking unit is mounted in any suitable place within the vehicle and comprises a clamp which is connected onto a linkage rod to the gear shift and which is normally freely movable with the movement of the gear shift. The clamp unit also comprises a plate portion having an aperture into which a cable having a lock pin on one end can extend when it is desired to prevent any movement of the clamp. The cable is able to extend the pin into and out of the aperture and clamp from a place remote from the clamp itself by a plunger arrangement which is normally extended in an unlocked position but when depressed or urged inwardly causes the entry pin at the other end to move into the aperture and prevent movement of the clamp and thereby prevent movement of the gear shift. A key may be turned to maintain the plunger in locked position against the action of a spring normally urging the unit into unlocked position.
