A door latch device includes: an open link including a lever main body, an inertia lever part, and a release energizing member configured to energize the inertia lever part to be maintained at an operating position with respect to the lever main body, an operation force of the door handle being not transmitted to the ratchet lever even in a state in which the lever main body is disposed at an unlocked position, in a case where the inertia lever part is disposed at a non-operating position against energizing force of the release energizing member; a ratchet lever; and a restriction mechanism disposed between the lever main body and the inertia lever part, the restriction mechanism being configured to restrict returning movement to the operating position in a case where the inertia lever part moves to the non-operating position.
