PROBLEM TO BE SOLVED: To prevent seizure caused by foreign matter mixed in lubricating oil. SOLUTION: In the inside of a balancer shaft 30 (rotating member) supported by a bearing member 15, there are formed an oil supply passage 35 in the axial direction and branch passages 39F, 39R radially branching from the oil supply passage 35 and opened to a slide contact area with the bearing member 15 in the outer peripheral face of the balancer shaft 30. The lubricating oil pressure-fed into the oil supply passage 35 through an inflow passage 36 passes the oil supply passage 35 and the branch passages 39F, 39R in sequence and is supplied to a gap between the balancer shaft 30 and the bearing member 15. The balancer shaft 30 is equipped with a filter which allows flow of the lubricating oil and regulates passage of foreign matter mixed in the lubricating oil. A filtration member 50 with the filter arranged in a path from the inflow passage 36 to the branch passages 39F, 39R is mounted detachably. COPYRIGHT: (C)2011,JPO&INPIT
