Japanese Patent JP7102795

B2

To reduce a dimension along an axial direction of drive transmission means for transmitting and releasing rotation drive force, relative to a drive structure comprising: a drive force transmission member which is driven to rotate by a drive source; and a coupling member which is movable in an eccentric direction and an axial direction with the drive force transmission means and coupled to the drive force transmission member so as to transmit rotation thereto.SOLUTION: A drive transmission mechanism comprises: drive means comprising a drive transmission shaft 581 on whose outer periphery, a plurality of salients are formed, and being driven to rotate; drive transmission means which is attached movably along an axial direction of the drive transmission shaft through an attachment hole comprising on its inner periphery, a plurality of recesses engaged to the plurality of salients, and to which rotation drive force is transmitted from the drive means; and gap formation parts each of which is provided on one of a tip of the drive transmission shaft and a base end of the attachment hole, and forms a gap for allowing inclination of the drive transmission shaft in a state in which the salients and recesses are engaged.SELECTED DRAWING: Figure 12
