Abstract
A sealing device is provided on the outer circumference of an oil pressure unit of the oil pressure rush adjuster, or on the partitioning wall of a sub-reservoir surrounding the oil pressure unit, or therebetween so as to provide a sealing between said partitioning wall and said outer circumference of the oil pressure unit while the engine in which the rush adjuster is mounted is stopped and so as to allow a portion of the oil to leak therebetween while the engine operates. Since the oil is perfectly prevented, while the engine stops, from leaking between the outer circumference of the oil pressure unit and the partitioning wall of the sub-reservoir, the oil amount residing in the reservoirs is enough even though not supplied from the cylinder head, and the air cannot be drawn into the high pressure chamber.
