In an apparatus for locking and unlocking a vehicle door, an inner cable, with one end connected to a rotor to make a twisting operation in response to the rotation of the rotor of a cylinder lock and the other end connected to a key operation input shaft of a door lock mechanism, is inserted through an outer casing with opposite ends connected to the cylinder lock and the door lock mechanism. A locking part capable of elastically engaging with an engaging part provided at a casing included by the door lock mechanism is provided at an end portion of the outer casing at a side of the door lock mechanism. An engagement release inhibiting member which is capable of inhibiting release of engagement of the engaging part with the locking part, is fitted to one of the end portion of the outer casing at the side of the door lock mechanism and the casing to be capable of being displaced between an engagement release allowing position which allows release of engagement and an engagement release inhibiting position which inhibits release of engagement. Therefore, a connecting state of the outer casing to the door lock mechanism can be prevented from being easily released.

Apparatus for locking and unlocking vehicle door

An apparatus for locking and unlocking a vehicle door includes a cylinder lock having a rotor, 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 for transmitting rotation of the rotor 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. The gear transmission mechanism is constructed by a face gear coaxially connected to the rotor, and a pinion gear which has an axial line perpendicular to an axial line of the face gear, is connected to the torque cable, and is meshed with the face gear. The pinion gear is accommodated in the gear case to be capable of being displaced in an axial direction in a limited range while keeping a meshed state with the face gear. Therefore, even if a variation occurs to the mounting position of the cylinder lock and the door lock mechanism to the door, reduction in the ease of assembling the torque cable to the door lock mechanism can be avoided.
