A variable valve device includes an outer body that a valve contacts at a side thereof, wherein an end of the other side is supported by a hydraulic lash adjuster, a bearing contacting a cam is formed in the center, and a stepped latching device insertion hole is formed in the center of the other side, an inner body that is located in the outer body, including a side portion that can rotate together with an end portion of the outer body around a valve stem shaft in the same axis, and the other portion is connected to a bearing shaft, a latching device that is inserted in the latching device insertion hole, and that selectively causes movement of the outer body depending on the movement of the inner body, and a lost motion spring that is formed outside of the outer body, and that provides an elastic force to enable the inner body to perform a lost motion. |
