A valve timing controller is provided with a driving rotor rotating along with a crankshaft, a driven rotor rotating along with a camshaft, a planetary gear performing a planetary motion to adjust a rotational phase between the camshaft and the crankshaft, a motor shaft rotating for controlling the planetary motion, a cylindrical planetary carrier supporting the planetary gear and being connected with the control shaft so that the planetary gear performs the planetary motion, and a lubricating mechanism. The lubricating mechanism includes an introducing port which opens on a side surface of the second rotor axially confronting the planetary carrier. The introducing port extends across a supporting outer surface and a connecting inner surface. The lubricant is introduced into an interior of the first rotor through the introducing port.
