PROBLEM TO BE SOLVED: To provide a connection structure for a gear and a shaft suitable for a resin gear capable of easily performing a phase alignment related to a device mounted on the shaft and the meshing of the gear mounted on the shaft with the other gear. SOLUTION: A mortise is formed at the center of a square set plate, a square recessed part in which the set plate is stored is formed in the surface of the portion of the resin gear to which the shaft is connected, and the set plate is installed. A tenon inserted into the mortise of the set plate is formed at the end of the shaft on a side to which the gear is connected. The length of the tenon is set so that, when the resin gear is connected to the shaft, first the mortise is engaged with the tenon, and then the installation of the mortise onto the tenon is advanced, and after the installation is advanced to some degree, the resin gear is meshed with a mating gear.
