Document Type and Number:
Japanese Patent JP2016012988
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotary body driving device excellent in assemblability and rotation controllability, capable of being assembled by accurately aligning rotation reference positions of a rotary body to be a load and a rotor, whose cost is reduced by omitting the number of components.SOLUTION: The rotary body driving device has a configuration in which a rotary body 3 is assembled to a rotor 11 so that circumferential positions of a reference reflection plane 3a1 and a position detecting magnet 5d1 correspond to each other by aligning positions of the position detecting magnet 5d1 formed by notching part of a circumferential wall of the rotor 11 to expose a rotor magnet 5d, a first positioning part 5e formed by corresponding to the position detecting magnet 5d1 at the rotor 11, and a second positioning part 3e formed by corresponding to the reference reflection plane 3a1 of the rotary body 3.
