PROBLEM TO BE SOLVED: To provide a vehicular seat device capable of reliably preventing a forward movement of a seated person and reliably constraining the seated person on a seat cushion when the seated person on the seat cushion is subjected to the forward movement while sinking on an upper surface of the seat cushion by its inertia force during the sudden deceleration when the vehicle travels forward. SOLUTION: During the sudden deceleration when a vehicle travels forward, an inertia mass 19 is rocked downwardly forward around its center 17 of axis by the forwardly moving inertia force P of the inertia mass 19, and a receiving member 16 interlocked with the inertia mass 19 is rocked A upwardly. An elastic body 28 is provided to urge the inertia mass 19 so that the center of gravity G of the inertia mass 19 forming the starting point of the inertia force P is relatively and upwardly moved I with respect to a supporting part 18a of a rocking bracket 18 when the inertia mass 19 is rocked C downwardly forward.
