Patent ID: 7578271

Claim:
A valve timing controller for controlling a valve timing of at least one of an intake valve and an exhaust valve which is opened/closed by a camshaft by torque transmitted from a crankshaft, comprising: a first rotary element including a first gear part for rotating in response to one of the crankshaft and the camshaft; a second rotary element including a second gear part neighboring to the first gear part in the axial direction for rotating in response to the other of the crankshaft and the camshaft; a third rotary element including a third gear part and a fourth gear part, the third gear part and the fourth gear part being meshed respectively with the first gear part and the second gear part and performing a planetary motion to vary a relative rotational phase between the first rotary element and the second rotary element; a stopper radially extending in one rotary element of the first rotary element and the second rotary element for regulating a relative rotational phase shift angle between the first rotary element and the second rotary element; and an interposing assembler provided either at an other rotary element of the first rotary element and the second rotary element or between the other rotary element and the third rotary element for rotatably interposing the stopper of the one rotary element in the axial direction.
