Claim 0:
1. An automobile door latch device, comprising:
a latch mechanism including a latch and a ratchet, the latch mechanism being configured to hold a door at a closing position by meshing the latch with a striker;
an electric releasing mechanism including a motor and a rotating cam configured to rotate in a first direction or a second direction that is a reverse direction from the first direction, from a reference position by power of the motor against a biasing force of a spring and return to the reference position by the biasing force of the spring, the electric releasing mechanism being configured to release meshing of the latch mechanism by power of the motor;
a manual releasing mechanism including an outside lever and an inside lever, the manual releasing mechanism being configured to release meshing of the latch mechanism by a manual operating force; and
a lock configured to switch between a locked state in which releasing meshing of the latch mechanism by an operation of the manual releasing mechanism is disabled and an unlocked state in which the releasing is enabled, wherein
when the lock is in the locked state and the rotating cam rotates by a predetermined angle in the first direction from the reference position by power of the motor against the biasing force of the spring the electric releasing mechanism is configured to switch the lock from the locked state to the unlocked state by releasing meshing of the latch mechanism and configured to switch the lock from the unlocked state to the locked state when the rotating cam returns to the reference position by the biasing force of the spring from a position to which the rotating cam has rotated by the predetermined angle.
