ーリのシール構造。 In a pulley for a V-belt continuously variable transmission, which has an operating hydraulic chamber on the back of the movable sheave that operates the movable sheave in the axial direction, the sleeve is attached to the outer periphery of the rotating shaft with a certain gap between it and the shaft. The movable sheave is supported on the outside of the sleeve so as to be movable in the axial direction, and a sealing member slidable on the sleeve is fixed to the inner diameter of the movable sheave,
A seal member that is slidable against the inner diameter of the movable sheave is fixed on the sleeve, and the space between the two seal members is drained through the oil drain hole formed in the sleeve and the gap between the sleeve and the rotating shaft. A seal structure for a pulley for a V-belt continuously variable transmission, which is characterized by communicating with an oil path.
