ユ調整可能なバルブロツカアーム。 A valve rocker arm body that is swingably attached to the rocker shaft and opens and closes an intake or exhaust valve at the other end by the rotation of a cam that slides in contact with one end; a cylinder hole that is opened and formed; a plunger that is slidably inserted into the cylinder hole in the axial direction and has a sliding surface that slides into contact with either the cam or the valve; and the interior of the plunger. A seat plunger that is fitted into the plunger and defines the interior of the plunger into a reservoir chamber and a high pressure chamber, and a communication hole formed in the seat plunger that allows a compensating flow of oil from the reservoir chamber to the high pressure chamber. a return spring provided in the high pressure chamber and urging the plunger and the seat plunger away from each other; and an air separation passage provided between the circumferential fitting surfaces of the cylinder hole and the plunger; An oil supply hole that communicates with the lower part of this air separation passage, an oil inlet that communicates the upper part of the air separation passage with the upper part of the reservoir chamber, and an outer periphery between the oil supply hole and the oil introduction hole of the air separation passage. A valve locking arm with adjustable lash, characterized by having an annular groove provided on the side and an air vent hole formed in the upper part of the groove.
