POWER TRANSMISSION APPARATUS
First Claim
1. A power transmission apparatus, comprising:
- a power transmitting unit which is disposed on a plane defined by a front-rear direction and a left-right direction which are at right angles to each other, and which transmits power in a non-contact manner to a power receiving unit installed in a vehicle which enables to move on the plane; and
a housing which accommodates the power transmitting unit, which is larger by a first specified amount in four directions than the power transmitting unit when the plane is seen from thereabove, and which projects vertically from the plane,wherein in a case where the power receiving unit is positioned to be included in the housing when the plane is seen from thereabove, the first specified amount is a value which satisfies at least one of conditions that a power transmitting efficiency between the power transmitting unit and the power receiving unit is equal to or greater than a predetermined value, and that a leakage magnetic filed strength is smaller than a predetermined value.

Abstract
A power transmission apparatus includes a power transmitting unit which is disposed on a plane defined by a front-rear direction and a left-right direction which are at right angles to each other, which transmits power in a non-contact manner to a power receiving unit installed on a vehicle which enables to move on the plane, and a housing which accommodates the power transmitting unit, which is larger by a first specified amount in four directions than the power transmitting unit when the plane is seen from thereabove, and which projects vertically from the plane. In the case where the power receiving unit is positioned to be included in the housing when the plane is seen from thereabove, the first specified amount is a value which satisfies at least one of conditions that a power transmission efficiency between the power transmitting unit and the power receiving unit are equal to or greater than a predetermined amount, and that a leakage magnetic field strength is smaller than a predetermined amount.
