COIL MEMBER, CONTACTLESS-TYPE POWER TRANSMISSION DEVICE, ELECTROMAGNETIC WAVE IRRADIATION/RECEPTION DEVICE, POWER TRANSMISSION/INFORMATION COMMUNICATION DEVICE, AND AUTONOMOUS MOBILE ROBOT SYSTEM

摘要

A first disclosure is a coil member wherein a lead wire is wound in oval shape, with an oval-shaped cross section being curved along a major-axis direction of the oval-shaped cross section and having a curvature axis in a direction parallel to a minor-axis direction of the oval-shaped cross section. A second disclosure is a contactless-type power transmission device provided with: a coil member as a first coil; a second coil; and a tilting shaft that makes variable, using the curvature axis as a rotating axis, an inclination between a central axis of the first coil, which is a rotational symmetry axis of the first coil, and a central axis of the second coil.
