Device recliner for vehicle

The invention is to be, and an object thereof is transmitted to the cam and then the rotational driving force of the lever socket is passed to the wedge located on the one side, the rotational drive force of the lever socket to another wedge which is located on the other side by a cam on the power recliner device to be passed to provide a power recliner devices that the reclining by a small operating force, and the operational load conditions as in the vibration and flutter of the gap between the developing part is not generated. The invention IX tunnel gear by the rotation of the first and second wedge and cam according to the rotation of the lever socket is coupled to the internal gear is eccentrically rotated in the power recliner device being the angle of the seat back adjustment; The power recliner apparatus, the rotation side of the lever socket is driven in contact with the first wedge, and the first wedge moves rotating in the rotational drive direction of the lever receptacle, rotating another aspect of the lever socket is driven is in contact with the cam and the cam is working rotation in the rotational drive direction of the lever socket and the rotation side of the cam that operates in contact with the second wedge is rotated to move the second wedge in the rotational drive direction of the lever socket, the first wedge and the cam due to the lever socket It has a sequential rotary motion and a second recline without vibration and flutter in a load state by the pivotal movement of the developer by the cam wedges are to occur.
