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

    【課題】従動ギアの回転速度を変更可能な駆動ギア機構を提供する。【解決手段】駆動機構(10)の第1駆動ギア部(21)および第1従動ギア部(31)の歯(21b,31b)のうち、回転軸(Ax,Bx)を結ぶ軸間線(L)上を最後に通過する第1の端の歯(21bx,31bx)の歯先から第1の端の歯(21bx,31bx)を有するギア部(21,31)の回転軸(Ax,Bx)までの半径方向距離(Ltx)と、第1の端の歯(21bx,31bx)の歯先と軸間線(L)上で対面する本体部の表面(31ax,21ax)から当該本体部(31a,21a)の回転軸(Bx,Ax)までの半径方向距離(Lsx)との和が、第2駆動ギア部(22)および第2従動ギア部(32)の基準円直径(R22,R32)との和以上である。【選択図】図7B
