Claim Text:
1. A valve timing control apparatus that is placed in a rotation transmission path, which conducts rotation from a drive shaft of an internal combustion engine to a driven shaft, wherein the valve timing control apparatus adjusts valve timing of a valve that is opened and closed by the driven shaft, the valve timing control apparatus comprising: a first rotatable body that is rotatable synchronously with one of the drive shaft and the driven shaft; a second rotatable body that is rotatable synchronously with another one of the drive shaft and the driven shaft; a sun gear that includes an internally toothed portion, which is coaxial with the first rotatable body; a plurality of fixing members that are placed on an outer side of the internally toothed portion in a radial direction and fix the sun gear and the first rotatable body together; a planetary gear that makes planetary motion while the planetary gear is meshed with the internally toothed portion; and a rotation transmission arrangement that changes a rotational phase of the second rotatable body relative to the first rotatable body by transmitting rotation of the planetary gear to the second rotatable body at a time when the planetary gear makes the planetary motion, wherein: the sun gear includes:
