Zusammenfassung:PURPOSE:To surely transmit rotation by engaging a driving gear and a driven gear which can be brought in mutual contact separation without generating interference phenomenon of their addendums. CONSTITUTION:In a gear transmission device transmitting rotation by engaging a driving gear 28 mounted on a movable shaft 25 capable of being approached or separated against a driven gear 23 mounted on a fixed shaft 22 with the gear 23, an elastic member 29 elastically deformable in the direction perpendicular to the axial direction is provided riding over supporting members 26, 27 supporting the driving gear 28 and the driving gear 28 between. When the driven gear 23 is engaged with the driving gear 28, if the opposed addendums 23A, 28A are confronted with each other so as to be in the interference state, the driving gear 28 is moved in the direction of separating from the driven gear 23 by elastic deformation of the elastic member 29 in the direction perpendicular to the axial direction.
