PROBLEM TO BE SOLVED: To provide a camshaft device capable of reducing torque, preventing reduction of service life of a bearing, and reducing dimension in the radial direction centered on a camshaft. SOLUTION: This camshaft device is provided with the camshaft 1, a cam 2 being separate from the camshaft 1, having a through hole, and attached to the camshaft 1 in an externally fitting manner, and a rolling bearing 3 having an inner ring and an outer ring composed of an annular integrated object and supporting the camshaft 1 rotatably. In this camshaft 1, a section where the cam 2 is attached and a section where the rolling bearing 3 is attached have the same diameter and are linear. COPYRIGHT: (C)2006,JPO&NCIPI
