To provide a vehicle seat having a pitching mechanism that is small in the number of components and is advantageous in strength and rigidity.SOLUTION: A vehicle seat includes: a base frame 90 attached to a vehicle cabin; a cushion frame 20 connected to a first connection point C1 of the base frame 90 so as to be capable of a forward tilting operation and slidable relative to the base frame 90; a back frame 30 provided so as to be capable of a reclining operation relative to the cushion frame 20; a front link 40 whose basal end 40b side is pin-connected to a second connection point C2 of the base frame 90 so as to be swingable and whose leading-end 40t side is pin-connected to the cushion frame 20 so as to be swingable; a lock unit 50 that locks, in a seated position, the cushion frame 20 to the base frame 90 to restrict a pitching operation of the main frame; and a release member that releases a locked state.SELECTED DRAWING: Figure 10
