Abstract

PURPOSE: To eliminate the leakage of oil from oil path by sealing the inside of runner boss under the condition that a sliding and moving portion between movable blade and runner boss is pressurized by a pressure oil.
CONSTITUTION: The pressure cylinder 22, having the spring the spring 24 to push the piston 23 to a fixed direction at all times in its inside, gives the pushing force of the spring 24 to the piston 23 to pressurize oil in the cylinder 22. The pressure cylinder 22 is provided on the periphery of the main shaft 2 to enable the pressurized oil to be supplied into the runner boss directly at all times even if the main shaft 2 is rotated. Thus, the leakage of oil from the oil supply path can be eliminated and maintenance and inspection for the pressure cylinder 22 and its attendant apparatus can be made easier.
