Claim:
1. A valve timing adjusting device for a driving force transmission system for transmitting driving force of an internal combustion engine from a drive shaft to a driven shaft, the valve timing adjusting device being configured to adjust opening and closing timing of at least one of an intake valve and an exhaust valve which are opened or closed by the driven shaft, the valve timing adjusting device comprising: a first rotation body that includes: a second rotation body that includes a second sun gear part inside of the first rotation body and that is connected to the other one of the drive shaft and the driven shaft through an inside of the sprocket part to be rotated corresponding to the other one of the drive shaft and the driven shaft, wherein: a planetary rotation body that includes a first planetary gear part in engagement with the first sun gear part, and a second planetary gear part in engagement with the second sun gear part, wherein the planetary rotation body makes a sun-and-planet motion inward of the first sun gear part and the second sun gear part to change a phase of the relative rotation between the first rotation body and the second rotation body; a planetary rotation body carrier that is supported by a radially inward end portion of the covering part and rotatably supports the planetary rotation body radially inward of the planetary rotation body; a shaft that is connected to the planetary rotation body carrier; and a motor on an opposite side of the covering part from the sprocket part and is capable of rotating the shaft.
