Abstract
A fin member is installed in an oil accumulating room. The fin member causes lubrication oil to follow rotation of the oil accumulating room so that the lubrication oil can be forcibly rotated. In this manner, a rotational speed difference between the oil accumulating room and the lubrication oil is made small, and an adequate oil supplying pressure is generated by the centrifugal force. As a result, a sufficient quantity of the lubrication oil can be supplied. Therefore, estimation of a supplying oil quantity becomes easy, and accuracy in prediction of the lubrication oil quantity actually used for the bearing lubrication can be improved.
