To provide a driving gear mechanism in which rotation speed of a driven gear can be changed.SOLUTION: Sum of a distance (Ltx) in a radial direction from teeth tips of teeth (21bx and 31bx) at a first end which lastly pass on an inter-shaft line (L) connecting rotation shafts (Ax and Bx) of teeth (21b and 31b) in a first driving gear part (21) and a first driven gear part (31) of a driving mechanism (10) to rotation shafts (Ax and Bx) of gear parts (21 and 31) having teeth (21bx and 31bx) at the first end and a distance (Lsx) in the radial direction from surfaces (31ax and 21ax) of main body parts opposing on the inter-shaft line (L) to the teeth tips of the teeth (21bx and 31bx) at the first end to rotation shafts (Bx and Ax) of the main body parts (31a and 21a) is equal to or more than sum of reference circle diameters (R22 and R32) of a second driving gear part (22) and a second driven gear part (32).SELECTED DRAWING: Figure 7B
