Rotating shaft support apparatus and magnetic motor having the same

A rotating shaft support apparatus comprising:

• a rotating shaft, of which one end is for being coupled to another rotating body;
• a housing in which the rotating shaft is housed, the housing being provided with a hole through which the one end of the rotating shaft is inserted and;
• a first bearing that is arranged inside the housing and that rotatably supports another end of the rotating shaft;
• and
• a spring that biases the rotating shaft in an axial direction, the rotating shaft being rotatably supported by the first bearing;
• wherein
• when the one end of the rotating shaft is not coupled to the other rotating body, axial run-out of the rotating shaft is suppressed by the one end of the rotating shaft being caused to come into contact with the housing by the spring, and
• when the one end of the rotating shaft is coupled to the other rotating body, the one end of the rotating shaft is caused to be separated from the housing in resistance to the biasing force of the spring.
