<p>PURPOSE:To provide an electromagnetic clutch of low leaking magnetic flux and high mechanical stability, by inserting a non-magnetic coupling member into grooves on the inside and outside circumferential surfaces of disc plates. CONSTITUTION:An annular coupling section 240 of To in width and Ho in height is provided between the coupled surfaces 221a, 222b of the first and the second disc plates 221, 222. The grooves 221b, 222b are provided on the coupled surfaces of the disc plates. The coupling member 223 made of such a metal as copper easy to plastically deform is inserted into the coupling section 240 and is pressed by metal dies having faces of width smaller than said width To. As a result, a coupling force P remains applied to the coupling member 223 to strongly push the coupled surfaces 221a, 222a of the disc plates 221, 222 open. The electromagnetic clutch of high mechanical stability is thus obtained.</p> |
