Abstract
A phase adjustment mechanism for setting a relative rotational phase of a driven-side rotational body to a drive-side rotational body of a valve opening-closing timing control device includes a output gear around a rotational axis, an input gear being rotated around an eccentric axis, and an eccentric member. The eccentric member includes an outer peripheral surface with a first arc portion, a second arc portion, a plate spring fitted between the first arc portion and the second arc portion, and a spaced portion. Each of the first arc portion and the second arc portion is disposed from a position less than 90 degrees to a position more than 90 degrees as a central angle with respect to the eccentric axis from a biasing direction of the plate spring in the peripheral direction.
