A door latch device includes a latch mechanism, an inner lever having a connection lever and an actuation lever, and a lock mechanism switching between unlocked and locked state. The lock mechanism includes a connection member capable of transmitting operation of the connection lever to the actuation lever, a first rotating lever rotated by a motor to first and second working positions, a second rotating lever rotatable to a first rotation position where the connection member is moved to an unlock position and a second rotation position where the connection member is moved to a lock position, a connection spring connecting the first rotating lever and the second rotating lever while allowing relative rotation of them, and a holding spring having a biasing force stronger than a biasing force of the connection spring and holds the first rotating lever at the first and second working positions.

The present invention relates to a vehicle door latch system, more particularly, relates to a vehicle door latch system whose locking driving unit comprises a motor, a first gear connected to the motor, and a second gear interlocked with the first gear, wherein a connect through hole wherein a key connect is penetrating through, and two of a rotating stopping portion wherein a locking stopping portion is caught by are formed spaced apart along the circumferential direction so that a locking member is moved as the motor operates, and two of a key stopping portion are formed spaced apart along the circumferential direction so that the locking member is moved as the key connect is rotated.

A vehicle door latch apparatus is provided that shortens the time to switch the locking lever between the locked position and the unlocked position. A vehicle door latch apparatus according to the present invention comprises a latch that is engaged with a striker in order to keep a vehicle door in a half-latched state or a full-latched state; a ratchet that is engaged with the latch in order to keep the latch engaged with the striker; an opening link 27 that abuts against the ratchet in order to release the ratchet from the latch when the opening link is moved in a door opening direction in an door opening operation of an outer door opening handle; a locking lever 28 that can be switched between a locked position that prevents the ratchet from being released by the opening link and an unlocked position that allows the ratchet to be released; and a locking actuator 39 that switches the locking lever between the locked position and the unlocked position. The locking actuator includes a motor 40 and an output wheel 42 that is driven by the motor, and the output wheel has a protruding or recessed first connecting part 45 and the locking lever has a recessed or protruding second connecting part 46 that is connected to the first connecting part.
