1. A system having a contact structure, wherein the system comprises a first electric device and a second electric device, wherein the contact structure causes the first electric device to be electrically connected to the second electric device in a state in which the first electric device is fitted to a recessed fitting part of the second electric device, the contact structure comprising:
a first terminal provided at a position recessed from a surface of an outer case of the first electric device; and
a second terminal configured to be a plate spring or a wire spring, the second terminal being provided on an inner wall of the fitting part of the second electric device to be brought into contact with a surface of the first terminal,
the second terminal including a contact projection projecting in an inward direction of the fitting part of the second electric device to be electrically brought into contact with the surface of the first terminal, and a cleaning projection located closer to an opening side of the fitting part of the second electric device than the contact projection and projecting in the inward direction to be brought into contact with the first terminal,
wherein before the cleaning projection climbs over the first terminal in response to a movement of the first electric device in a fitting direction relative to the second electric device, the cleaning projection is pushed in an outward direction of the fitting portion by the outer case of the first electric device or the first terminal so that the contact projection moves in the outward direction of the fitting part, whereby the contact projection is not brought into contact with the surface of the outer case of the first electric device or the surface of the first terminal, and
wherein after the cleaning projection climbs over the first terminal, the cleaning projection is not pushed by the outer case of the first electric device or the first terminal so that the contact projection moves in the inward direction of the fitting part, whereby the contact projection is brought into contact with the surface of the first terminal.
