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 formed with an opening, and a bottomed cylindrical plunger having a sliding surface that is slidably fitted in the cylinder hole in the axial direction and slides into contact with either the cam or the valve; , a cylindrical seat plunger that is slidably fitted in the plunger in the axial direction, a high pressure chamber defined inside the plunger by the seat plunger and the plunger, and an upper end of the seat plunger that is connected to the cylinder. A reservoir chamber defined inside the seat plunger in contact with the top surface of the hole, and a check valve provided in the communication hole formed at the bottom of the seat plunger to allow compensatory flow of oil from the reservoir chamber to the high pressure chamber. and a return spring provided in a high-pressure chamber to bias the bottom of the plunger and the bottom of the seat plunger in a direction to separate them from each other, and a flange is provided at the upper end of the seat plunger radially inwardly or radially outwardly. A valve locking arm with adjustable latches that is integrally provided in an annular shape.
