徴とする内燃機関の吸排気弁リフト制御装置。 The lift control cam has a lift control cam formed with a plurality of cam surfaces and a cam control shaft connected to the lift control cam via an elastic member, and the lift control cam rotates in stages by elastic energy stored in the elastic member. A variable intake/exhaust valve lift mechanism that varies the lift characteristics according to changes in lift characteristics, a drive means that rotates the cam control shaft, a position detection means that detects the actual rotational position of the cam control shaft, and a position detection means that detects the actual rotational position of the cam control shaft. In an internal combustion engine intake/exhaust valve lift control device comprising a feedback control means for outputting a manipulated variable to the drive means according to a deviation between the position and the target position, the drive means, the cam control shaft, and the position detection means are the same. An intake/exhaust valve lift control device for an internal combustion engine, characterized in that the device is connected via a deceleration mechanism with a deceleration rate, and the position detection means is a one-rotation type position detection means.
