Abstract
A gearwheel unit includes a gear body and a clutch gear. The gear body includes a gear part and a positioning part. The gear part is configured and arranged to transmit rotation of a rotational shaft with a prescribed change gear ratio. The positioning part is integrally formed with the gear part at a position spaced apart from the gear part by a prescribed distance in an axial direction so that a prescribed open space is formed between the positioning part and the gear part. The clutch gear is fixedly coupled to the gear body as being positioned with respect to the gear body by the positioning part so that at least a part of the clutch gear overlaps the prescribed open space formed between the positioning part and the gear part of the gear body when viewed in a radial direction.
