Abstract
PURPOSE: To protect a gear from seizing to the inside face of a casing by providing grooves in either of a side face of the gear or the inside face of the casing.
CONSTITUTION: Grooves 20, 21, 22, and 23 are provided for a portion of a pressurized fluid to be reached to at least one side of side faces of gears 6 and 7, and the inside face of a casing 1 that faces 6 and 7. With this constitution, when a gear has moved to the inside face of the casing, the pressure in the grooves increases and the side face of the geadr is prevented from coming into contact with the inside face of the casing; thus protecting the gear from seizure.
