Vorrichtung für die Verriegelung und die Entriegelung einer Fahrzeugstür

摘要

An apparatus for locking and unlocking a vehicle door includes a cylinder lock (21) having a rotor (36), a door lock mechanism including a key operation input shaft which rotates to switch a locked state and an unlocked state of a door, and a torque cable (23) for transmitting rotation of the rotor (36) to the key operation input shaft. One end of the torque cable is connected to the rotor via a gear transmission mechanism accommodated in a gear case (40). The gear transmission mechanism is constructed by a face gear (53) coaxially connected to the rotor (36), and a pinion gear (54) which has an axial line perpendicular to an axial line of the face gear (53), is connected to the torque cable (23), and is meshed with the face gear (53). The pinion gear (54) is accommodated in the gear case (40) to be capable of being displaced in an axial direction in a limited range while keeping a meshed state with the face gear (53). Therefore, even if a variation occurs to the mounting position of the cylinder lock (21) and the door lock mechanism to the door, reduction in the ease of assembling the torque cable (23) to the door lock mechanism can be avoided.
