Electromagnetic coupling device, and door handle and vehicle door having electromagnetic coupling device

An electromagnetic coupling device electromagnetically connecting a door handle side circuit adapted to be provided in a door handle which is so mounted to a vehicle door main body as to rotate relative thereto and a door main body side circuit adapted to be provided in the vehicle door main body, the door main body including a door glass which can be raised and lowered with respect to the door main body, the electromagnetic coupling device comprising:

• a door handle side coupling unit electromagnetically connected with the door handle side circuit;
• a door main body side coupling unit electromagnetically coupled with the door handle side coupling unit without making contact therewith;
• a handle side support unit that supports the door handle side coupling unit in the door handle;
• a door side support unit that supports the door main body side coupling unit in the door main body;
• a window outer side coupling unit disposed at the same side of the door glass as the door handle, and electromagnetically connected with the door main body side coupling unit;
• and
• a window inner side coupling unit disposed at the opposite side of the door glass from the door handle, and electromagnetically connected with the door main body side circuit,
• wherein at least one of the handle side support unit and the door side support unit restricts the relative movement, caused by rotation of the door handle, of the door handle side coupling unit and the door main body side coupling unit, and
• wherein the window outer side coupling unit and the window inner side coupling unit are disposed at opposing positions with the door glass interposed therebetween, and are electromagnetically coupled.
