<p><P>PROBLEM TO BE SOLVED: To provide an electromagnetic clutch that suppresses the generation of vibration caused by the eccentricity of a cam member. <P>SOLUTION: The electromagnetic clutch 10 includes: an inner shaft 3; a first cam member 61 provided on the outer circumference of the inner shaft 3 so as to integrally rotate with the inner shaft 3; a second cam member 62, in which an insertion hole 623 for inserting the inner shaft 3 is formed, which is disposed movably in the axial direction between a first position where it is close to the first cam member 61 in distance and a second position where it is separated farther than the first position in distance to the first cam member 61 and generates a cam force by relative rotation with the first cam member 61; an electromagnetic coil 5, which generates a magnetic force that moves the second cam member 62 in the axial direction. The inner shaft 3 is formed in such a shape that makes the movable distance in the radial direction of the second cam member 62 with respect to the rotation axis thereof becomes smaller at the first position than at the second position. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
