シール構造。 A first oil seal is interposed between the inner periphery of the first case and the outer periphery of a second case that is rotatably fitted into the same case, and rotates within the inner periphery of the second case. A second oil seal is interposed between the outer periphery of the shaft that can be fitted, and the inside of the first case is liquid-tightly divided into two storage chambers accommodating different drive mechanisms and different oils in the axial direction. In the oil seal structure, the first
and a pair of annular oil seals interposed with a predetermined gap in the axial direction as a second oil seal, or a double-structured oil seal with a pair of annular lips with a predetermined gap on the back. The second case is provided with through holes that communicate with the gaps between the first and second oil seals, and the first case is provided with through holes that communicate with the gaps between the first and second oil seals.
An oil seal structure characterized by providing a gap between the oil seals, a space in a double structure part of the case, and a pair of through holes that communicate with the outside air.
