To provide a power transmission device and an electric vehicle including a magnetic material clamp component that can be fixed to a bus bar while suppressing a decrease in electromagnetic noise absorption characteristics.SOLUTION: There are provided a power transmission device and an electric vehicle each including a bus bar and a magnetic clamp component mounted on the bus bar. The magnetic body clamp component includes a first magnetic body and a second magnetic body having shapes in which a through hole is formed when magnetic bodies are combined to face each other in the first direction, a holder that holds the first magnetic body and the second magnetic body in a combined state, and a rubber member having a first surface and a second surface sandwiching the bus bar, at least a part of which is disposed in the through hole. In the cross section orthogonal to the penetration direction of the through hole, the length between the opposing surfaces of the inner peripheral surface of the through hole that oppose each other in the first direction is larger than the width of the rubber member sandwiching the bus bar in the first direction.SELECTED DRAWING: Figure 5
【課題】電磁ノイズの吸収特性の低下を抑制しつつバスバーへの固定が可能な磁性体クランプ部品を備えた電力伝送装置及び電動車両を提供する。【解決手段】バスバーと、バスバーに装着された磁性体クランプ部品と、を備える電力伝送装置及び電動車両である。磁性体クランプ部品は、互いが第1方向に対向して組み合されたときに貫通孔が形成される形状の第1磁性体及び第2磁性体と、第1磁性体と第2磁性体とを組み合わされた状態に保持する保持器と、バスバーを挟み込む第1面及び第2面を有し、少なくとも一部が貫通孔に配置されるゴム部材とを備える。そして、貫通孔の貫通方向に直交する断面において、貫通孔の内周面のうち互いに第1方向に対向する対向面間の長さが、バスバーを挟み込んだゴム部材の第1方向の幅よりも長い。【選択図】図5
