DOOR LATCH DEVICE
In order to more reliably prevent a situation in which a door is unnecessarily opened, an open link 20 includes a lever body 21, an inertia lever 22, and a torsion spring 24, in which the inertia lever 22 is capable of transmitting an operation force to a ratchet lever 14a only when a door handle is opened in a state in which the lever body 21 is disposed at an unlocked position and disposed at an operating position, the torsion spring 24 functions to tilt the inertia lever 22 with respect to the lever body 21 when the inertia lever 22 rotates to a sensing position against a biasing force, and the lever body 21 includes a regulating projection 21Ba that prevents the inertia lever 22 from moving to the operating position across the sensing position by facing a block portion 22B when biased in a rotation direction by the torsion spring 24 in a state in which the inertia lever 22 is tilted.
