To suppress the elongation of a length occupied by a reduction gear and drive wheels in an axial line direction.SOLUTION: A moving body 1 comprises a main body 10, an axle 21, drive wheels 3, a motor 4, a reduction gear 5 and a shaft joint 6. The drive wheels 3 are arranged around the axle 21 so as to be rotatable. The reduction gear 5 is attached to the axle 21, reduces a rotation output of the motor 4, and transmits it. The reduction gear 5 has an output shaft 51 along a center axial line 210 of the axle 21. The shaft joint 6 transmits the rotation output of the reduction gear 5 to the drive wheels 3. The shaft joint 6 has a cylindrical part 61 which is annular in shape when viewed in the center axial line 210 direction, and accommodating at least a part of the reduction gear 5 therein. The cylindrical part 61 has an input part 611 at one side in the center axial line 210 direction, and has an output part 612 at the other side. The cylindrical part 61 has an absorption part 610 which can absorb a deviation and a deflection angle between the rotation center axial line 510 of the output shaft 51 and the rotation center axial line 300 of the drive wheels 3, between the input part 611 and the output part 612.SELECTED DRAWING: Figure 4
【課題】減速機と駆動輪の軸線方向に占める長さが長くなるのを抑えること。【解決手段】移動体1は、本体10、車軸21、駆動輪3、モータ4、減速機5及び軸継手6を備える。駆動輪3は、車軸21の回りに回転可能に配置される。減速機5は、車軸21に取り付けられ、モータ4の回転出力を減速して伝達する。減速機5は、車軸21の中心軸線210に沿う出力軸51を有する。軸継手6は、減速機5の回転出力を駆動輪3に伝達する。軸継手6は、中心軸線210方向に見て環状となり、内部に減速機5の少なくとも一部を収容する筒状部61を有する。筒状部61は、中心軸線210方向の一方側に入力部611を有し、他方側に出力部612を有する。筒状部61は、入力部611と出力部612との間に、出力軸51の回転中心軸線510と駆動輪3の回転中心軸線300との間の偏差及び偏角を吸収可能な吸収部610を有する。【選択図】図4
