The picture heating roller of the air where the perforation hole

摘要

PROBLEM TO BE SOLVED: To provide an image heating device in which a snap ring can be preventing from coming off a fixing roller.;SOLUTION: A bearing 11b and a heat insulation bush 70b are extrapolated to a fixing roller 7, and then a spacer 60 is extrapolated. In this case, a key part 60a of the spacer is fitted into a through hole 7a formed in the fixing roller 7. Then, a C type snap ring 50b is extrapolated around the fixing roller 7. In this case, a projection 50e formed on the C type snap ring 50b is fitted into the through hole 7a into which the key part 60a of the spacer 60 has been fitted. As a result, the spacer is not rotated relatively to the C type snap ring 50b, so that the C type snap ring 50b can be prevented from unexpectedly coming off the fixing roller 7.;COPYRIGHT: (C)2013,JPO&INPIT
