摘要： A lift-variable valve-operating system for an engine, includes a subsidiary cam swingably carried on a movable support shaft. A cam follower is operatively connected to an engine valve and follows the subsidiary cam. The lift amount of the engine valve is varied by displacing the movable support shaft. The subsidiary cam has an oil sump provided in an upper surface and opens upwards to store oil. The subsidiary cam is provided with an abutment face abutting against the cam follower. The abutment face includes a lift portion for turnably driving the cam follower; and a base circle portion connected to the lift portion and which retains the cam follower in a rest state. The subsidiary cam is also provided with a lubricating oil bore for guiding the oil in the oil sump to the base circle portion.
