徴とする軸受部の潤滑油シール構造。[Claims for Utility Model Registration] A lubricating oil seal structure for a bearing portion, in which a bearing housing of a rotating shaft is provided with an oil seal for preventing lubricating oil from a bearing portion of the rotating shaft from leaking to the outside, comprising: A pressurized chamber is provided on the side opposite to the bearing section so as to surround the oil seal and the outer peripheral surface of the rotating shaft, so that the pressure is higher than that on the bearing section side due to the difference between the inflow and outflow of compressed air. Features a lubricating oil seal structure for the bearing.
