Power Transmission Device

Abstract

A power transmission device, which is used for a contactless power transmission to a movable body moving on a travelling surface in a power transmission direction parallel to the travelling surface, including a power transmission coil and a shielding plate, wherein, the power transmission coil is installed so that a coil surface is approximately vertical to the travelling surface, and at least a part of the shielding plate is disposed inside the region on the travelling surface sandwiched between a plane surface defined by a coil surface of the power transmission coil and a plane surface defined by a coil surface of a power receiving coil mounted on the movable body.
