摘要： PROBLEM TO BE SOLVED: To prevent collision of a contact part with a rolling element of separate outer races and to appropriately lubricate the rolling element. SOLUTION: The bearing device for the engine includes a roll bearing for supporting a crankshaft provided with the pair of semicircular separate outer races, the engine body member provided with a bearing forming a half of the circular bearing hole to which the rolling bearing is mounted, a cap member fixed to the bearing and forming the other half of the circular bearing hole. The bearing device for the engine includes clearance formed between the joint of the bearing and the cap member and the pair of separate outer races and an oil supply passage communicating with the clearance. The pair of separate outer races are arranged so that the respective contact parts of the pair of separate outer races which contact with each other are positioned inside the clearance. The contact parts are formed so that radially outward displacement of the contact parts is promoted in the case that a force in a contacting direction works. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To supply oil pressure from a head side oil passage formed on a bearing member to a phase variable mechanism without a large drop thereof and give no harmful effect on a rolling bearing itself when a camshaft is supported by a bearing member of a cylinder head through the rolling bearing. SOLUTION: An adjacent bearing member 20 positioned adjacently to the phase variable mechanism 30 is supported by the camshaft 1 through the rolling bearing 50. Annular space A, B (annular groove parts 25, 26) having centers on the camshaft 1 are formed between the adjacent bearing member 20 and the surfaces of diameter expanded flange parts 2, 3 formed on the camshaft 1 opposing in an axial direction. Head side oil passages 61, 65 and camshaft side oil passage 62, 66 (67) are communicated to the annular spaces A, B. COPYRIGHT: (C)2010,JPO&INPIT
