PURPOSE:To enable the detection of the abnormal supply state of oil air to a lubricated object with low-priced constitution in an oil air lubricating system. CONSTITUTION:An orifice 10 is formed at the intermediate part of a drain pipeline 8 for discharging lubricating oil from a bearing 7 lubricated by oil air, and a pressure sensor 11 is provided at the drain pipeline 8 upstream of the orifice 10. In the case of the detection value of the pressure sensor 11 being lower than the value in the normal state, the supply state of oil air to the bearing 7 is judged to be abnormal.
