<P>PROBLEM TO BE SOLVED: To provide an electromagnetic coupling device that can reduce releasing sound during the collision of an armature plate with a hub when releasing. <P>SOLUTION: The electromagnetic coupling device includes a magnetic pole body 2, a plate (brake plate or rotor) 3, an armature plate 5, a hub 4 disposed coaxial to a shaft to hold the armature plate 5 so that it may reciprocate and slide, and a leaf spring 6 disposed over the hub 4 and the armature plate 5 to press the armature plate 5 in a direction away from the plate against the attraction of the magnetic pole body 2. In a part where the armature plate 5 and the hub 4 face each other during releasing of the armature plate 5 from the plate 3, an annular elastic sheet 7 is attached to one of the armature plate 5 and the hub 4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
