バルブタイミング装置。In an internal combustion engine, a part of the engine is provided with an oil gear lary and a vertical sleeve insertion hole that communicates with the oil gear lary, and a sleeve having an oil hole on the circumferential wall is rotatably inserted into the sleeve insertion hole, and the rotation of the sleeve allows oil to be inserted. A plunger that can be passed through the hole to the oil gear rally, has a diagonal notch at its lower end, is rotatably and slidably inserted into the upper part of the sleeve, and a valve lifter is slidably inserted into the lower part of the sleeve. A hydraulic chamber is formed between the valve lifter and the lower end of the plunger, and at least one of the sleeve and the plunger is provided with a mechanism for rotating the sleeve and the plunger, so that the upper end of the plunger can come into contact with a cam for driving an intake valve of the engine, A variable valve timing device characterized in that a lower end of a valve lifter can come into contact with an intake valve.
