The door lock according to the invention comprises a lock body, a bolt, a follower, a driver on both sides of the follower, and a latch solution to connect at least one of the drivers in force transmission connection and out of force transmission connection with the follower. The door lock further comprises a baffle plate between the follower and the driver at least on one side of the follower. The baffle plate comprises at least one support surface, which is set against the lock body or against a part which is connected to the lock body in a fixed manner. The baffle plate can thus not be rotated in relation to the lock body. A baffle plate which cannot be rotated prevents turning force from being transmitted from the driver to the follower.
