Abstract
To provide an inner shim that is unlikely to fall off from a spring retainer even when an anomalous operation of a valve occurs. A spring retainer fixed to the upper end portion of a valve shaft has a shim-attachment hole. An inner shim is fitted into the shim-attachment hole. The bottom face of the inner shim is in contact with the upper end portion of the valve shaft, and the top face of the inner shim is positioned below the upper edge of the shim-attachment hole. A tappet is disposed above the spring retainer, and is allowed to move freely in the axial direction of the valve shaft. A shim-holding projection sticks out from the under face of the tappet, and extends downward. The projection enters, from above, the inside of the shim-attachment hole, and is in contact with the top face of the inner shim.
