To provide a door latch actuator that shortens operation time for switching a door latch device to a lock state and an unlock state. When a drive portion 50 is rotated in one direction, one of locking/unlocking drive projections 501 a comes in contact with an upper driven portion 65b to move an actuating member 52 to a lock position. When the actuating member 52 is moved to the lock position, one of the locking/unlocking drive projections 501 a leaves a recess 65a, and a stopping projection 501 c comes in contact with the actuating member 52 to stop rotation of the drive portion 50. When the drive portion rotates in an opposite direction, the other locking/unlocking drive projection 501 b comes in contact with the lower driven portion 65b, so that the actuating member 52 is moved toward an unlock position. When the actuating member 52 is moved to the unlock position, the other locking/unlocking drive projection 501 b leaves the recess, and the stopping projection 501 d comes in contact with the actuating member 52 thereby stopping rotation of the drive portion.
