Abstract

PURPOSE: To prevent liquid leakage certainly for a long period by allowing the liquid in a casing to get into the shaft hole due to rise of inner pressure, and accumulating the liquid temporarily in the drain hole which is closed by a check valve mechanism and allowing the liquid to return into the casing.
CONSTITUTION: A casing is constituted through the connection of a crank case 2 and a case cover 3 with a gasket 1. On the case cover 3, a shaft hole 7 is formed, closely to the opening edge side, which holds a governor shaft 6 as movable shaft projected outside freely rotatably. In the middle part of the shaft hole 7, a circumferential groove 8 is formed, and continuously to the circumferential groove 8, a drain hole 9 is formed. The drain hole 9 is directed to the installation surface side of the gasket 1 and opened in the crank case 2. While, at one part of the gasket 1, an elongated part 10 is formed, and closely contacted with the opening surface of the drain hole 9 by the pressure increase in the crank case 2, and thus the function as a check valve mechanism 11 is fulfilled.
