POWER TRANSMISSION DEVICE AND POWER RECEPTION DEVICE
First Claim
1. A power transmission device comprising:
- a first coil formed so as to surround a first winding axis extending in an up-down direction; and
a second coil formed so as to surround a second winding axis extending in the up-down direction,the first coil and the second coil being configured such that a first current direction and a second current direction are opposite to each other during power transmission,in the first current direction, a current that flows through the first coil flowing so as to be wound around the first winding axis, andin the second current direction, a current that flows through the second coil flowing so as to be wound around the second winding axis,the first coil includinga first adjacent portion located adjacent to the second coil, anda first spacer portion located on an opposite side of the first adjacent portion with respect to the first winding axis,the second coil includinga second adjacent portion located adjacent to the first coil, anda second spacer portion located on an opposite side of the second adjacent portion with respect to the second winding axis,the first adjacent portion being located higher than the first spacer portion.

Abstract
A power transmission device includes: a first coil; and a second coil. The first coil and the second coil are configured such that a first current direction and a second current direction are opposite to each other. The first coil includes a first adjacent portion located adjacent to the second coil, and a first spacer portion located on an opposite side of the first adjacent portion. The second coil includes a second adjacent portion located adjacent to the first coil, and a second spacer portion located on an opposite side of the second adjacent portion with respect to the second winding axis. The first adjacent portion is located higher than the first spacer portion.
