PROBLEM TO BE SOLVED: To provide a step motor ensuring productivity.SOLUTION: A step motor 6 which rotary-drives a rotary pointer, includes: a radial bearing 87 which radially supports an output gear 636 having an output shaft portion 637 rotating around a rotary center axis C together with the rotary pointer and a final step gear portion 638 expanding from the output shaft portion 637 to an outer peripheral side, and an output shaft portion 637 inserted into an inner side on one side in the axial direction than the final step gear portion 638; a speed reduction mechanism R which has an intermediate gear 635 meshed with the final step gear portion 638 and a magnet gear meshed with the intermediate gear 635 on the one side in the axial direction than the final step gear portion 638; and a projecting body 89 which projects out from the radial bearing 87 to the other side in the axial direction, in a specific area A expanding from a vertical cross-section L including the rotary center axis C to the opposite side to the intermediate gear 635 in the output gear 636.SELECTED DRAWING: Figure 7

    【課題】生産性の確保されたステップモータの提供。【解決手段】回転指針を回転駆動するステップモータ6は、回転指針と共に回転中心線Cまわりに回転する出力軸部637、及び出力軸部637から外周側へ広がっている最終段ギア部638を、有する出力ギア636と、最終段ギア部638よりも軸方向一方側にて内周側に挿入された出力軸部637を、ラジアル支持しているラジアル軸受87と、最終段ギア部638が噛合している中間ギア635、及び最終段ギア部638よりも上記軸方向一方側にて中間ギア635が噛合しているマグネットギアを、有する減速機構Rと、出力ギア636において回転中心線Cを含む縦断面Lから中間ギア635とは反対側に広がる特定領域Aにて、ラジアル軸受87から軸方向他方側へ突出している突起体89とを、備える。【選択図】図7
