<p><P>PROBLEM TO BE SOLVED: To achieve, at low cost and with excellent workability, a bearing structure capable of preventing the smooth rotation of a shaft from being impaired even if thermal change is caused in a clutch by the energization of an exciting coil. <P>SOLUTION: A bearing member 6 for pivotally supporting the shaft 30 is fitted into a shaft insert hole in a field storing the exciting coil. The bearing member 6 is locked to the bottom face of the field 1 by projections 64a and 64b for rotation stopper formed on a flange part 63. Also, a slit 65 is axially cut on the opposite side of a side where the projections 64a and 64b are formed. Even if the bearing member 6 is contracted with age by receiving the thermal cycle of the exciting coil, since the slit 65 is formed, the bearing member 6 is not locked to the shaft 30. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
