Camshaft device

摘要

An intake camshaft device 1 includes an intake camshaft, a first rolling bearing and a second rolling bearing for rotatably supporting both end parts of the intake camshaft, and a first sliding bearing and a second sliding bearing for rotatably supporting the intake camshaft between the first and second rolling bearings. The first rolling bearing is arranged in a same plane as a rotation plane of a sprocket for an intake cam. In other words, the first rolling bearing is positioned in a plane which is overlapped with a plurality of teeth of the sprocket for the intake cam, and perpendicular to a center axis. The first sliding bearing is disposed adjacent to the first rolling bearing backward in an axial direction.
