    摘要: A bearing device includes a shaft, a sleeve and a thrust plate. The shaft includes a convex portion having a curved surface provided at one end thereof. The sleeve includes an inner circumferential surface opposed to an outer circumferential surface of the shaft. The thrust plate includes a concave portion having a curved surface and arranged to make contact with the convex portion of the shaft. The shaft is supported by the sleeve and the thrust plate such that it may rotate about the central axis with respect to the sleeve and the thrust plate. A curvature radius of the concave portion is greater than a curvature radius of the convex portion but equal to or smaller than about 2.0 times of the curvature radius of the convex portion.

    摘要: A V-type DOHC engine has first and second banks. The end of the cylinder row in the first bank on one end of the engine retracts from that of the cylinder row in the second bank. A first camshaft in each bank is driven by the crankshaft by way of a first transmission mechanism which is disposed on said one end of the engine, and the first and second camshafts in each bank are connected by a second transmission mechanism which is disposed between the first transmission mechanism and the cylinder row of the bank. The end portion of the first camshaft in the first bank on said one end of the engine is supported by a pair of bearings one disposed between the first and second transmission mechanisms and the other disposed between the second power transmission mechanism and the cylinder row in the first bank. The end portion of the second camshaft in the first bank on said one end of the engine is supported by a bearing disposed between the second transmission mechanism and the cylinder row in the first bank. The end portion of each of the camshafts in the second bank on said one end of the engine is supported by a bearing disposed between the first and second transmission mechanisms.
