Claims

[Claims for Utility Model Registration] 1. The Rocker arm shaft 6 which is the fulcrum of the Rocker arm 3 operated by the valve closing cam 1
is a forced opening/closing valve mechanism that intersects the camshaft 4 at right angles. 2. The forced open/close type valve operating mechanism according to claim 1, wherein the valve spring retainer ring 10 and the valve spring retainer 12 are configured to freely slide between the retainer rings 8 and 9 as stoppers. 3. The forced opening/closing type valve operating mechanism according to claim 1, wherein the valve 7 opens and closes the valve while always having gaps 17 and 18 between the opening cam 2, the closing cam 1, the rocker arm 3, and the valve retainer 12.
