A motor vehicle door latch device comprises a locking motor; a locking rotary member that can be rotated by the locking motor; locking mechanism comprising a mechanical element that can be shifted to an unlock state or a lock state by rotation of the locking rotary member; a releasing motor; and an electric release lever pivotally mounted to a housing via a release shaft and rotated by the releasing motor to enable an engagement mechanism to be released regardless of a state of the locking mechanism. If an entering line along which a striker enters a striker entering groove of a body to engage with the engagement mechanism is defined as a striker entering line, a case for the locking motor is positioned above the striker entering line and a case for releasing motor is positioned below the striker entering line.
