ABSTRACT:
A combination changing mechanism for the lock of a luggage case, primarily characterized in that the operation part for opening the lock is provided in the form of a circular disc. A rotation disc is provided below the operation disc which has a rod extending downwards therefrom into the combination changing mechanism for connection with a lower disc. By this construction, the relationship between the combination dials and the corresponding sleeves can be controlled such that when the operation disc is rotated into its lock-opening position, the combination cannot be changed, when the operation disc is then rotated through 180.degree., the combination can be changed, and when the operation disc is then rotated through 90.degree., neither the lock can be opened nor the combination can be changed.
