PROBLEM TO BE SOLVED: To provide a driving and braking device of a wheel, which can suppress the size of the device in a radial direction and an axial direction even when an outer diameter of a projection part on a vehicle body center side of a wheel is large.SOLUTION: A driving and braking device of a wheel comprises: an electric motor 2 for driving, which is mounted on a wheel 11 of a wheel 1 in an in-wheel manner; a power transmission mechanism 3A which comprises an internal tooth gear 31 for output interposed between the wheel 11 and the electric motor 2 and connected to the wheel 11, and can change a rotational speed; a bearing 6 for rotatably supporting the wheel 11 on a vehicle body; and a brake mechanism 7 for applying a brake force to the wheel 11. The electric motor 2, the power transmission mechanism 3A, a hub 12 of the wheel 11 are arranged along an axle direction of the wheel 1 from a vehicle body center side IS to a vehicle body side OS in this order. The internal tooth gear 31 for output and the hub 12 are adjacent to each other along the axle direction. A connection member 5 for power-connecting an outer peripheral part of the internal tooth gear 31 for output to the hub 12 is provided. The bearing 6 and the brake mechanism 7 are arranged side by side on the outer peripheral side of the connection member 5 along the axle direction.SELECTED DRAWING: Figure 1

    【課題】ホイールのハブの車体中心側の凸部の外径が大きい場合であっても、装置の大きさを径方向及び軸方向に抑えることができる車輪の駆動制動装置を提供する。【解決手段】車輪1のホイール11にインホイール式に装備された駆動用の電動モータ2と、ホイール11と電動モータ2との間に介装されホイール11に連結された出力用内歯ギヤ31を有し回転速度を変更可能な動力伝達機構3Aと、車体にホイール11を回転自在に支持する軸受6と、ホイール11に制動力を付与する制動機構7とを備え、電動モータ2,動力伝達機構3A及びホイール11のハブ12が、車輪1の車軸方向に沿って車体中心側ISから車体側方OSにこの順に配置され、出力用内歯ギヤ31とハブ12とが車軸方向に沿って隣接し、出力用内歯ギヤ31の外周部とハブ12とを動力連結する連結部材5が装備され、軸受6及び制動機構7は、連結部材5の外周側で車軸方向に沿って並設される。【選択図】図1
