Abstract

A direct acting hydraulic lash adjuster comprising a hydraulic unit (Y) for the lash adjuster incorporated in a bucket (X) provided with an oil supply port (2) and a sub-reservoir (4) for supplying working oil sent via the oil supply port (2) to a main reservoir (52) on the hydraulic unit (Y) side that is formed around the hydraulic unit (Y) by installing a sleeve (3) in such a manner as to extend from the inside of the bucket (X) to surround the hydraulic unit (Y), wherein an oil passage (1) is provided which communicates with the oil supply port (2) and passes circumferentially in the sub-reservoir (4) so as to be opened thereto, so that oil inside the sub-reservoir (4) is made difficult to leak to thereby prevent the entry of air into the sub-reservoir (4) and the main reservoir (52).
