Abstract

In this vehicle mounting structure of a contactless power reception device, a power reception-side coil that configured to be mounted on a bottom surface of a vehicle body and that has an electrically conductive wire wound with the vehicle longitudinal direction as the coil axis is attached to the vehicle body by means of a fastening member made of a magnetic body. The fastening member is disposed to the outside of the power reception-side coil in a direction perpendicular to the coil axis.

Claims

1. A vehicle mounting structure of a contactless power reception device, comprising:

a power reception-side coil configured to be mounted on a bottom surface of a vehicle body and to contactlessly receive power transmitted from a power feeding-side coil, the power reception-side coil having a conductive wire wound with a vehicle longitudinal direction as a coil axis; and

a fastening member made of a magnetic body to fasten the power reception-side coil to the vehicle body, wherein

the fastening member is disposed to an outside of the power reception-side coil in a direction perpendicular to the coil axis,

the power reception-side coil is attached to the bottom surface of the vehicle body through an attachment member,

the attachment member includes a vehicle body-side attachment part to be fixed to the bottom surface of the vehicle body and a coil-side attachment part to be fixed to the power reception-side coil by the fastening member, and

the coil-side attachment part is disposed at a position further away from the coil axis of the power reception-side coil than the vehicle body-side attachment part.
