Abstract

A non-contact power receiving device includes a power receiving device, a shielding member, supports, a housing, and fastening elements. The power receiving device is mounted on a vehicle body and configured to receive wirelessly transmitted electric power. The shielding member is provided between the vehicle body and the power receiving device. The supports are provided so as to project from the vehicle body. The housing is provided between the supports and in which the power receiving device is disposed. The fastening elements are respectively mounted on the supports so as to be disposed on the opposite side of the housing and that respectively fasten the shielding member to the supports.

Claims

1. A non-contact power receiving device comprising:

a power receiving device mounted on a vehicle body and configured to receive wirelessly transmitted electric power;

a shielding member disposed between the vehicle body and the power receiving device;

supports that are provided so as to project from the vehicle body, and spaced apart from each other in a first direction that intersects a direction in which the supports project from the vehicle body;

a storage portion in which the power receiving device is disposed; and

fastening elements that respectively fasten the shielding member to the supports, wherein

the supports include first walls that project from the vehicle body and are spaced apart from each other in the first direction, and second walls that project from the vehicle body and are spaced apart from each other in the first direction,

the two first walls are disposed between the two second walls in the first direction,

the storage portion is disposed between the two first walls,

the shielding member includes;

a board that is disposed in the storage portion and on which the power receiving device is mounted; and

two arms that are coupled to the board, extend from the storage portion, and are bent along the support,

the fastening elements fasten the two arms to the two second walls respectively, and

the supports are respectively disposed between the fastening elements and the power receiving device.

2. The non-contact power receiving device according to claim 1,

wherein the fastening elements each include a bolt;

and

wherein a center line of the bolt is perpendicular to the direction in which the supports project from the vehicle body.
