<P>PROBLEM TO BE SOLVED: To provide a drive transmission, a sheet feeder, and an image forming device, preventing a shaft coupling from being damaged even when a force in a direction to rotate a drive shaft is applied to a driven shaft. <P>SOLUTION: A drive shaft side shaft coupling part 71A provided to the drive shaft 71 is engaged with a driven shaft side shaft coupling part 73A provided to the driven shaft 73 by an urging member for urging at least one of the drive shaft 71 and the driven shaft 73. The drive shaft side shaft coupling part 71A and the driven shaft side shaft coupling part 73 are shaped so that when a force for rotating in one direction is applied to the driven shaft 73 and the driven shaft 73 is relatively rotated with respect to the drive shaft 71, the driven shaft 73 moves in the direction to release the engagement with the drive shaft 71 while resisting the urging force of the urging member. <P>COPYRIGHT: (C)2010,JPO&INPIT |
