A combination lock has a keyless lock main body mounted on a housing part, a toothed rod, an engaging rod, a turnable rod and a locking rod. The toothed rod has engaging teeth, and is passed into numeral discs of the lock main body such that the toothed rod is released to be movable, and fixed in a locked position by the numeral discs. The toothed rod has a protruding plate on an outer end. The engaging rod is passed through the housing part, and has a front engaging end, and an intermediate recessed portion. The turnable rod is passed into the lock main body, and the housing part with a semicircular lower end pushing block connecting the recessed portion. The turnable rod has an intermediate portion having a flat side. The protruding plate abuts the flat side to prevent the turnable rod from turning in the locked position. In the unlocked position, the turnable rod is turned for the pushing block to move the engaging rod rearwards. Thus, the engaging end disengages from the locking rod for same to be removable from the locked object.
