Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a drive transmission device which can reduce an occupation space of a rotating shaft in an outer diameter direction.SOLUTION: A drive transmission device comprises: a first input-side rotating body 11 and a second input-side rotating body 212 which are arranged on an input-side rotating shaft 201; an input-side clutch 205 for switching drive transmission and drive blockage between the first input-side rotating body 11 and the second input-side rotating body 212; a first output-side rotating 21 body and a second output-side rotating body 222 which are arranged on an output-side rotating shaft 202; an output-side clutch 6 for switching the drive transmission and the drive blockage between the first output-side rotating body 21 and the second output-side rotating body 222; and a drive gear 3 which is drive-connected to the first input-side rotating body 11. The first input-side rotating body 11 and the first output-side rotating body 21 are drive-connected to each other so as to reversely rotate, and the second input-side rotating body 212 and the second output-side rotating body 222 are drive-connected to each other so as to rotate in the same direction while either of the rotating bodies is constituted of an internal tooth gear, and the other is constituted of an external tooth gear.SELECTED DRAWING: Figure 4
