Claims

[Scope of utility model registration request]

A valve rocker arm body that is swingably supported on a rocker shaft and swings by the rotation of a cam that slides on one end to open and close each intake or exhaust valve that is operatively connected to the other end; The cylinder hole is slidably inserted in the axial direction of the cylinder hole formed in one end of the rocker arm body so as to open downwardly.
A bottomed cylindrical plunger, a valve seat fitted into the plunger so as to separate the inside of the plunger into a first oil chamber and a second oil chamber, and a valve seat provided in a through hole of the valve seat. In addition, a first check valve for allowing oil to flow only from the first oil chamber to the second oil chamber, and a bottom of the plunger and the valve seat are spaced apart from each other in the second oil chamber. A return spring is arranged so as to elastically bias it in a direction, and a return spring is arranged in an oil collection hole that communicates with the cylinder hole and opens upward, and is funnel-shaped as a whole and has flexibility. and a second check valve, when the oil pressure in the first oil chamber decreases, the oil stored in the oil collecting recess formed on the inner circumferential surface of the second check valve is transferred to the second check valve. In a lash-adjustable valve rocker arm in which oil flows into the first oil chamber from a slit formed at the lower end, oil stored in the oil collecting recess is formed on the upper inner circumferential surface of the oil collecting recess. A lash-adjustable valve rocker arm comprising an oil scattering prevention protrusion for preventing oil scattering.
