Abstract: A rotary latch lock for a vehicle door has a lock case forming a cut-out recess for a lock pin; a first rotatably mounted rotary latch engageable with the lock pin; a first rotary latch spring for imposing a force on the first rotary latch; a rotatably mounted actuating lever engaging in the lock case; a first locking pawl pivoting about a first pivot axis; and a guide device for locating, centering and guiding the vehicle door during opening and closing of the vehicle door. The first rotary latch, the first latch spring and the first locking pawl are arranged within the lock case. The first locking pawl engages the first rotary latch, causing the first rotary latch to be maintained in a locked position engaging the lock pin. The actuating lever actuates the first locking pawl, causing it to release the first rotary latch from its locked position.
