Abstract:
1. A valve timing controller that controls opening-and-closing timing of an intake valve or an exhaust valve which is driven by a driven shaft by changing a rotation phase of the driven shaft to a driving shaft of an internal combustion engine, the valve timing controller comprising: a rotation transmit component that is rotatable integrally with one of the driving shaft and the driven shaft; a housing including an outer shape part fixed to the rotation transmit component and a plurality of partition arts extending from the outer shape part inward in a radial direction so as to partition inside of the outer shape part into a plurality of oil pressure chambers; and a vane rotor including a boss part which is rotatable integrally with the other of the driving shaft and the driven shaft inside the housing and a plurality of vane parts radially extending from the boss part so as to divide each of the oil pressure chambers into an advance chamber and a retard chamber, the vane rotor relatively rotating relative to the housing on an advance side or a retard side according to a pressure of operation oil in the advance chamber and the retard chamber, wherein the outer shape part of the housing has a dome shape, the outer shape part of the housing has a dome part and a rib part extending from a central portion to an outer edge of the dome part, and the rib part has a thickness which is larger than a thickness of the dome part.
