Abstract: A valve timing controller has a driving rotor, a driven rotor, and a planet gear engaged with the driving rotor and the driven rotor to control a rotation phase of the driven rotor relative to the driving rotor by carrying out planet movement. The driven rotor has a contact surface in contact with a tip end of a chamfering portion of a camshaft, and a feed port passing through the driven rotor in an axial direction to introduce lubricant supplied from the camshaft into the driving rotor. The feed port has an outer edge part located on a radially outer side. The outer edge part, on a side adjacent to the contact surface, is located on a radially outer side of the tip end of the chamfering portion and is located on a radially inner side of an outer circumference part of the journal portion.
