Abstract
A driving apparatus which is capable of smoothly moving a follower by a cam portion, and realizes the stopper structure of the follower by a small number of components without the size increased. The driving apparatus comprises an up cam gear having an up radial cam and an up thrust cam, and a down cam gear unit having a down radial cam and a down thrust cam. The up cam gear and the down cam gear unit mesh with each other in a vicinity of a region in which a lift amount of the up radial cam with respect to the follower increases. In a vicinity of a position at which the up cam gear and the down cam gear unit mesh with each other, a lift amount of the up thrust cam is larger than a lift amount of the down thrust cam in the thrust direction.
