A valve timing controller is provided with a first rotary element including a first gear part, a second rotary element including a second gear part, and a third rotary element including a third gear part and a fourth gear part. The third gear part and the fourth gear part are meshed respectively with the first gear part and the second gear part. A stopper is provided so as to extend in the first rotary element in the radial direction for regulating a relative rotational phase shift angle between the first rotary element and the second rotary element. An interposing assembler is provided on the second rotary element for rotatably interposing the stoppers in an axial direction.
