Abstract: In a valve timing adjusting device, a second rotation body includes a second sun gear part provided inside of a first rotation body, and is connected to a drive shaft or a driven shaft through inside of the sprocket part to be rotated corresponding to the drive shaft or the driven shaft. When the second rotation body is brought into contact with the sprocket part, rotation of the second rotation body relative to the first rotation body is restricted. A planetary rotation body includes a first planetary gear part engaged with the first sun gear part, and a second planetary gear part engaged with the second sun gear part. 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.
