The engagement holes 42a and 42b are engaged with the locking claws 41e and 41f of the attachment portion 41 so that the attachment portions 41 can be detachably fixed. Each engagement hole 42a, 42b of the cover part 42 is formed in the side wall part which can be expanded with a finger | toe, and it can detach | leave from each latching claw 41e, 41f of the attachment part 41 by expanding the same part. It is.
[0015]
The operation cable 50 transmits the operation of the inner handle (not shown) assembled inside the door of the automobile door (not shown) to the inside lever 31, as shown in FIGS. 9, 10, and 13. The outer tube 51 having one end fitted and fixed in the mounting hole 23c (see FIG. 8) of the bracket 23, and the outer tube 51 is movably inserted into the outer tube 51, and one end is connected to the mounting hole 31a of the inside lever 31 And an inner wire 52.
[0016]
In the automobile door lock assembly of the present embodiment configured as described above, when the protector 40 is opened as shown in FIG. 2 with the assembly mounted on the automobile door, FIG. 9 and FIG. As shown in FIG. 10, the operation cable 50 can be attached and detached, and the operation cable 50 can be easily attached while the assembly is attached to the automobile door. . Therefore, there is no need to attach the operation cable 50 to the assembly before the assembly is mounted on the automobile door, and the assembly is made compact (the package size is reduced) to facilitate transportability (distributability). ) Can be improved.
[0017]
Further, in the present embodiment, with the assembly attached to the automobile door, the protector 40 is opened as shown in FIG. 2 and the operation cable 50 is attached as shown in FIG. 9 and FIG. Thereafter, when the protector 40 is closed as shown in FIG. 13, the inside lever 31 with the operation cable 50 assembled and the mounting portion of the operation cable 50 (the extension portion of the inner wire 52 from the outer tube 51). And the connection part of the inner wire 52 and the inside lever 31) can be covered and protected by the protector 40. Therefore, it is possible to prevent the inner wire 52 or the inside lever 31 from being operated unnecessarily, thereby improving the anti-theft property of the vehicle, and preventing dust and water from being attached to the mounting portion of the operation cable 50. The dustproof / waterproof performance of the cable 50 can be improved.
[0018]
Moreover, in this embodiment, since the protector 40 can be opened and closed by a tool-free manual operation, the protector 40 can be easily opened and closed when the assembly is mounted on the automobile door. It is possible to easily open and close the protector 40 when replacing the operation cable after the assembly is mounted on the automobile door. Therefore, it is possible to improve workability when the operation cable 50 is attached or replaced. Moreover, in this embodiment, since the protector 40 is a resin molded product integrally molded with resin, mass production is possible, and the protector 40 can be manufactured at low cost.
