PROBLEM TO BE SOLVED: To provide an oil feeder capable of operating an oil feeding part even when the viscosity of an oil is rather high in the oil feeder having an oil pump feeding the oil from an oil storage part to the oil feeding part. SOLUTION: A parallel circuit comprises a first feed passage 15a having a check valve 45 to prevent the oil from returning from an oil feed part 100 side to an oil storage part 20 side and a second feed passage 16 without a check valve. The parallel circuit is formed in series with the oil pump 30 between the oil storage part 20 and the oil feed part 100. The oil feeder further comprises a switching means 50 switching the second feed passage 16 in a communicable state. COPYRIGHT: (C)2007,JPO&INPIT
