To provide a light-weight gear with a shaft capable of resisting high torque.SOLUTION: A gear 100 with a shaft comprises a shaft member 110, and a gear body 120 that is joined in a state where the shaft member 110 is inserted along a rotational axis r and is softer than the shaft member 110. The tooth part 121 provided on the outer peripheral surface of the gear body 120 has a lead angle γ1 of 15 degrees or more and 25 degrees or less. The shaft member 110 comprises a plurality of projections 111 extending along the tooth trace of the tooth part 121 on the outer peripheral surface joined to the gear body 120.SELECTED DRAWING: Figure 3

    【課題】軽量で高トルクに耐える軸付歯車の提供。【解決手段】軸部材110と、回転軸rに沿って軸部材110が挿通状態で接合され、軸部材110より軟質の歯車本体120とを備える軸付歯車100であって、歯車本体120の外周面に設けられる歯部121は、15度以上、25度以下の進み角γ1を有し、軸部材110は、歯車本体120と接合される外周面に歯部121の歯筋に沿って延在する複数の突条111を備える。【選択図】図3
