A door lock apparatus includes a casing having a lock mechanism disposed therein, an actuating mechanism disposed on the casing to actuate the lock mechanism, and a protective member covering the actuating mechanism. The apparatus is provided with pins for retaining the actuating mechanism on the casing, and engagement portions are provided on the pins and the casing, respectively. The protective member is provided with retaining portions which are engageable with the engagement portions, respectively, so that the engagement portions and the retaining portions are fitted with each other to rigidly secure the protective member to the casing. Accordingly it is possible to mount the protective member firmly and easily. Since the protective member can be molded from a resin material, it is possible to lower the production cost and reduce the overall weight of the product. In addition, since there is no need for special means such as rivets, it is possible to mount the protective member at a reduced cost.
