Patent ID: 8251029

Claim:
A valve timing controller which adjusts a valve timing of a valve opened/closed by a torque transmitted from a crankshaft to a camshaft of an internal combustion engine, the valve timing controller comprising: a first rotor rotating along with one of the crankshaft and the camshaft; a second rotor accommodated in the first rotor and rotating along with the other of the crankshaft and the camshaft; a planetary gear accommodated in the first rotor and having an external gear engaging with an internal gear provided to the first rotor or the second rotor the planetary gear performing a planetary motion to adjust a relative rotational phase between the crankshaft and the camshaft; a control shaft rotating for controlling the planetary motion; a cylindrical planetary carrier accommodated in the first rotor and having a supporting outer surface which supports the planetary gear thereon, the cylindrical planetary carrier having a connecting inner surface to which the control shaft is connected so that the planetary gear performs the planetary motion according to a rotation of the control shaft; a lubricating means having an introducing port which opens on a side surface of the second rotor axially confronting the planetary carrier, the introducing port extending across the supporting outer surface and the connecting inner surface, the lubricating means introducing a lubricant into an interior of the first rotor through the introducing port; and a fastening member fastening the second rotor to the camshaft, wherein the first rotor rotates along with the crankshaft, the second rotor rotates along with the camshaft, the second rotor is provided with a through-hole through which the fastening member is inserted, wherein the introducing port has a first side-opening confronting the planetary carrier and a radially inside opening communicating with the through-hole, and the introducing port has a bottom portion located radially outward relative to the radially inside opening and the supporting outer surface.
