PROBLEM TO BE SOLVED: To provide a door end lock for fittings capable of preventing the unlocking of a locking piece by easily rotating a driving shaft of an outside cylinder lock even if a thief launches an attack at least against the outside cylinder lock by making use of a drill for a door. SOLUTION: A protection structure of the cylinder lock as the lock for the fittings is so constituted that a circular wall 61a inserted into an outside cylinder from the outside is fixed to an internal space 2 of a stile of a sliding door in a state to accompany an interior wall surface side of a decorated plate 5 and that a case-shaped first hard protector 61 having a cylindrical protection wall 61b surrounding the circumferential wall of the outside cylinder 50 is fixedly placed.
