<p>PURPOSE:To obtain an electromagnetic clutch which is simple in structure and capable of effectively reducing noise caused at the time of switching. CONSTITUTION:A driving side rotor 13 is rotatably arranged, while a circular contact shoe 16 is provided on a driven side hub 14 through a plate spring 15 oppositely to a contact face of the rotor 13. The contact shoe 16 is attracted to the contact face of the rotor 13 by the attraction force of an electro-magnet 12 arranged on the rotor side for transmission of power. The plate spring 15 has an outer circular part fixed to the contact shoe 16 and an inner circular part fixed to the driven hub 14. The outer and inner circular parts are integrally connected to each other by at least three connection parts. Widths of the connection parts are different from one another.</p> |
