Abstract

Disclosed is a noncontact power transmission system including a power transmission device for transmitting power to a power receiving device in a noncontact manner. The power transmission device includes a cover covering a portion of an outline of the power transmission device where the power transmission device faces the power receiving device, a base covering another portion of the outline of the power transmission device where the power transmission device does not face the power receiving device, a magnetic body arranged in a space enclosed with the cover and the base, a coil bobbin covering the magnetic body partially or entirely, and a coil wire which is wound around the coil bobbin and which generates a magnetic flux upon receiving an alternating current. The coil bobbin includes a load support.

First claim

What is claimed is:

1. A noncontact power transmission system including a power transmission device for transmitting power to a power receiving device in a noncontact manner, the power transmission device comprising:
a cover covering a portion of an outline of the power transmission device where the power transmission device faces the power receiving device;
a base covering another portion of the outline of the power transmission device where the power transmission device does not face the power receiving device;
a magnetic body arranged in a space enclosed with the cover and the base;
a coil bobbin covering the magnetic body partially or entirely; and
a coil wire which is wound around the coil bobbin and which generates a magnetic flux upon receiving an alternating current, wherein
the coil bobbin includes a load support, and
the load support is disposed on an outer surface of the coil bobbin, extends from inside of turns of the coil wire to pass between the turns of the coil wire, and has a height protruding from an outer periphery of the turns of the coil wire.
