A clutch mechanism for a vehicle seat, the clutch mechanism comprising: a pressure-receiving member rotatably assembled to a frame of a seatback of the vehicle seat; a connecting arm having a weight and a pin, and provided rotatably to the pressure-receiving member; and a swinging member provided rotatably to the frame of the seatback of the vehicle seat, and including a rib which is formed with a cutout capable of receiving the pin of the connecting arm, wherein while inertia force occurring due to a crash of a vehicle from behind acts on the weight, when the pressure-receiving member rotates upon receipt of a seatback load of a passenger of the vehicle seat, the connecting arm moves along with the rotation of the pressure-receiving member so that the pin of the connecting arm pushes either one of (i) an edge of the rib and (ii) a cutout of the rib while entering the cutout, to rotate the swinging member.
