Abstract
A camshaft unit for a vehicle includes: a cam gear shaft-coupled to one end of a camshaft; a scissors gear provided at one side of the cam gear while having the camshaft as a concentric axis and relatively rotated with respect to the cam gear; a coil spring provided between the cam gear and the scissors gear, having one end fixed to one side surface of the cam gear and the other end fixed to the other side surface of the scissors gear; and a snap ring installed in a groove formed in one side surface of the scissors gear and inhibiting separation of the scissors gear in an axial direction. In particular, the coil spring transfers a torque of the cam gear to the scissors gear while being elastically restored depending on rotation of the cam gear.
