載の可変バルブリフト装置。[Scope of Claim for Utility Model Registration] 1. In a cam device for driving intake and exhaust valves, which includes a multiple cam in which multiple cams are superimposed, a rocker arm that contacts the multiple cam, a push rod that connects the rocker arm and the valve, etc., the engine is operated. It has a locker arm that selects and moves the optimum cam profile depending on the situation, and the locker arm is engaged with an engagement groove in the frame that holds the locker arm so that the locker arm does not move during the cam lift or just before the start of the cam lift. 1. A variable valve lift device characterized in that a stopper is provided for regulating the valve lift, and the stopper operates at a timing by utilizing a lift caused by a cam profile of a multiple cam. 2. The variable valve lift as set forth in claim 1 of the utility model registration claim, in which either surface of a cam profile selected depending on the operating condition of the engine and a rocker arm that contacts the cam profile is made of wear-resistant chips such as ceramics. Device.
