Title:

ROTATION TRANSMISSION STRUCTURE, IMAGE FORMING APPARATUS AND TRANSMISSION MEMBER

Document Type and Number:

Japanese Patent JP2019078341

Kind Code:

A

Abstract:

To improve rigidity of a rotation member with respect to a force in a rotation direction in a configuration where a first shaft is rotationally driven, power is supplied to a second shaft, the rotation of the first shaft is transmitted to the second shaft and the first shaft and the second shaft are insulated, in relative to a configuration in which an input portion and an output portion of the force in the rotation direction in the transmission member are disposed while being displaced in an axial direction.SOLUTION: A rotation transmission structure 70 comprises a shaft member 72 which is rotationally driven, a driving roll 74 to which power is supplied, a first engagement part 76, a second engagement part 85, and a transmission member 84. The first engagement part 76 is positioned separately from a shaft center of the shaft member 72 and rotated integrally with the shaft member 72. The second engagement part 85 is positioned separately from a shaft center of the driving roll 74 and rotated integrally with the driving roll 74. The transmission member 84 includes transmission part 114 and 116 which are held between the first engagement part 76 and a second engagement part 85 in a rotation direction, and transmits the rotation of the shaft member 72 to the driving roll 74.SELECTED DRAWING: Figure 12
