PROBLEM TO BE SOLVED: To provide a handcart reduction gear capable of providing a buffer function by magnetic resistance, when moving, and a handcart using the same.SOLUTION: A handcart reduction gear 300 is applied for a wheel shaft of a handcart, and comprises: a wheel 400; a following gear 500; a reluctance motor 600; and a resistance element 700. The wheel 400 is attached to a wheel shaft in a manner of being capable of turning, and has a drive gear 410 which rotates following to rotation of the wheel 400. The following gear 500 is provided on one side of the wheel shaft, and the following gear 500 is engaged to the drive gear 410 and is driven, and has a connection part 510. The reluctance motor 600 is connected to the connection part 510 and is driven by the following gear 500. The resistance element 700 is electrically connected to the permanent magnet.SELECTED DRAWING: Figure 4ACOPYRIGHT: (C)2020,JPO&INPIT【課題】移動する際、磁気抵抗により緩衝機能を提供する手押し車減速装置及びそれを応用した手押し車を提供する。【解決手段】手押し車減速装置300は、手押し車の車輪軸に応用するとともに、車輪400、従動歯車500、リラクタンスモータ600及び抵抗素子700を備える。車輪400は、車輪軸に旋回可能に取付けられるとともに、車輪400の回転に伴って回転する駆動歯車410を有する。従動歯車500は、車輪軸の一側に位置し、従動歯車500が駆動歯車410と噛合されて駆動されるとともに、接続部510を有する。リラクタンスモータ600は、接続部510と接続されて従動歯車500により駆動される。抵抗素子700は、永久磁石と電気的に接続される。【選択図】図4A
