Abstract
A lash adjuster has a plunger assembly comprising a plunger and a plunger cap. A separator is provided in the plunger cap to prevent the air mixed in the introduced oil from flowing into a reservoir chamber. The plunger cap further has a valve device in addition to the separator for preventing external air from being drawn into the lash adjuster.
