<p><P>PROBLEM TO BE SOLVED: To prevent occurrence of abnormal sound when rotating a cylindrical shaft integrally with a clutch gear. <P>SOLUTION: This electromagnetic clutch 1 is provided with the cylindrical shaft 5 having a locking part 5B capable of inserting an output rotary shaft being an object for output in power transmission internally and transmitting rotation force to the output rotary shaft in an internally inserted condition and the clutch gear 10 attached to an outer peripheral side of the cylindrical shaft 5 and a one end side in the axial direction of the cylindrical shaft 5 rotatably. The locking part 5B is provided at a position closer to the clutch gear 10 than a central position of the cylindrical shaft 5 and in the vicinity of a mounting position of the clutch gear 10 in the axial direction of the cylindrical shaft 5 to suppress instantaneous moving of the cylindrical shaft 5 during rotation. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
