PROBLEM TO BE SOLVED: To easily reduce a number of components in comparison with a conventional example.SOLUTION: In a protruding part 51 of a rotor 5, an engaging part 54 is provided which is engaged with an engaged part 205 formed on an inner peripheral surface of an insertion hole 203. For that reason, components for making a housing 1 support the rotor 5 become unnecessary like a conventional example. As a result, a number of components can be easily reduced as compared with a conventional example. |
