Abstract:
1. An electromagnetic switching device comprising: an electromagnetic device comprising a coil bobbin, an excitation coil, a movable core and a fixed core, in which said movable core comes into contact with or separates from said fixed core in response to energization of said excitation coil wound around said coil bobbin, a contact device with a fixed contact and a movable contact which comes into contact with or separates from the fixed contact in conjunction with a movement of said movable core of said electromagnetic device, and a boxy case for housing said electromagnetic device and said contact device, wherein said coil bobbin has a flange at its end in an axis direction of the coil bobbin, said case having, on its inner surface, a recess in which a periphery of the flange of said coil bobbin is fitted, a cushioning member for absorbing an impact to be transmitted from said electromagnetic device to said case being disposed in said recess, and wherein only a part of the electromagnetic device is supported by said case, said part of the electromagnetic device being the periphery of the flange of said coil bobbin, said periphery being supported by said recess of said case through said cushioning member wherein said recess is formed at a lateral side of inner surface of said case, and said cushioning member is interleaved between said recess and the periphery of the flange of said coil bobbin.
