PROBLEM TO BE SOLVED: To cause a plurality of gears to be easily engaged to each other when the plurality of gears, with their rotation axes being arranged in parallel to each other, are stored in a housing from a direction of each of their rotation axes.SOLUTION: This invention provides a system in which a rotor gear 17a and a large gear 17e of an intermediate gear 17d engaged to each other in a row 17 of transmission gears, a small gear 17g of the middle gear 17d and a rotor gear 17a having a less number of teeth of an output gear 17j or end surfaces of the teeth 17b, 17h of the small gear 17g are provided with semi-sphere protrusions 17c, 17i. Due to this arrangement, when the middle gear 17d is stored afterwards in the housing 13 storing the rotor gear 17a or the output gear 17j, the large gear 17e rides over the rotor gear 17a or the small gear 17g rides over the output gear 17j, a mere application of slight vibration to the housing 13 enables these riding-over states to be resolved.

    【課題】互いの回転軸を平行に配置した複数の歯車をそれぞれの回転軸方向からハウジング内に収容する際に歯車同士が噛合しやすいようにする。【解決手段】変速歯車列17の互いに噛合するロータギア17aと中間ギア17dの大歯車17eや、中間ギア17dの小歯車17gと出力ギア17jのうち、歯数の少ないロータギア17aや小歯車17gの歯部17b,17hの端面に、半球状の突起17c,17iを突設した。このため、ロータギア17aや出力ギア17jを収容したハウジング13に中間ギア17dを後から収容する際に、大歯車17eがロータギア17aに対して乗り上げたり、小歯車17gが出力ギア17jに対して乗り上げた場合に、僅かな振動をハウジング13に加えるだけでそれらの乗り上げ状態を解消させることができる。【選択図】図8
