发明名称 Wireless charging system
摘要 Wireless charging system suppressing reduction of an electric power feeding efficiency due to imperfect alignment caused between a transmitter and a receiver unit. Included are a first 18 and a second coil portion 15 fixed to a first 14 and a second magnetic member 21, respectively, and close to each other to be disposed so as to face each other, thereby feeding electric power from one coil portion to the other coil portion. Further included is a convex portion 24 mounted to the first magnetic member to protrude toward the second magnetic member when the first and the second coil portion are coaxially disposed; a cover 27 covering the second coil portion; and a concave portion 29 provided in the cover so as to face the convex portion when the first and the second coil portion are coaxially disposed. The convex portion contains as a material thereof a magnetic material.
