Abstract
A single-row planetary bearing includes a single row of spherical rolling elements between an outer ring and an inner ring. A planetary gear is supported by a thrust bearing portion and is radially supported by the outer ring. The planetary gear performs a planetary motion while engaging with a driving rotor and a driven rotor at an eccentric side to adjust a rotational phase between the driving rotor and the driven rotor. The thrust bearing portion supports the planetary gear that is tilting with respect to the revolution centerline. The planetary gear has a recessed portion opened toward the thrust bearing portion. When the rotational phase is adjusted to a specific phase, the recessed portion is positioned at an anti-eccentric side opposite to the eccentric side with respect to a rotation centerline of the planetary gear.
