Abstract: A bearing portion of a planetary rotatable body for providing bearing support in a thrust direction is defined as a planetary thrust bearing portion. A driving-side rotatable body or a driven-side rotatable body, which is configured to contact the planetary thrust bearing portion in the thrust direction, is defined as a specific rotatable body. A bearing portion of the specific rotatable body for providing bearing support in the thrust direction is defined as a specific thrust bearing portion. In a parallel state where the specific thrust bearing portion and the planetary thrust bearing portion are parallel to each other, the specific thrust bearing portion and the planetary thrust bearing portion contact with each other only on one of an eccentric side and a counter-eccentric side of the planetary rotatable body while the counter-eccentric side is opposite to the eccentric side.

Abstract: A drive-side rotor is rotated synchronously with a crankshaft. A driven-side rotor is rotated integrally with a camshaft. An internal gear section is formed at the driven-side rotor. An Oldham coupling includes: a driven Oldham flange that is formed at the drive-side rotor; a drive Oldham flange that is formed at the planetary rotor; and an Oldham intermediate that is configured to synchronize rotation of the driven Oldham flange and rotation of the drive Oldham flange while permitting eccentricity between the driven Oldham flange and the drive Oldham flange. There is satisfied a relationship of θ2
