A door lock disposed on a door leaf includes a casing, a bolt member, a latch member, an auxiliary latch member and a transmission unit. When the door lock is in an open state, the bolt member is retracted into the casing and held by the transmission unit. During a closing operation of the door leaf, the latch member and the auxiliary latch member are successively pushed into the casing to actuate the transmission unit, so that the transmission unit releases the bolt member when the door leaf is closed, and that the bolt member automatically projects out of the casing to lock the door leaf.
