PROBLEM TO BE SOLVED: To provide a rotor driving device for moving a drive transmitting member along a driving shaft, changing a driven side joint portion of a rotor to be driven and a driving side joint portion of the drive transmitting member from a separated condition into a joined condition, restricting the movement amount of the drive transmitting member with the fitting of a slit in the drive transmitting member to a shaft on the driving shaft, and giving the joined condition thereto when a pin is located at one end of the slit and the separated condition thereto when the pin is located at the other end of the slit, preventing the switching from the separated condition into the joined condition from being hindered due to the pin held in the slit at one end. SOLUTION: The slit 160 is formed in an egg shape so that the degree of fitting the pin 8 to the slit 160 is higher at one end of the slit 160 than at the other end. |
