What is claimed is: 1 . A refueling port, comprising: a refueling port main body made of resin; an inlet fitting formed in a tubular shape and arranged at an inlet opening of the refueling port main body; a cover made of resin and formed in a tubular shape, molded separately from the inlet fitting, mounted on the outer peripheral side of the inlet fitting, and fitted to the refueling port main body; and a ground fitting formed in a long shape and connected to the inlet fitting; wherein the ground fitting comprises: an exposed portion arranged to face an outer peripheral surface of the cover; and an insertion portion formed by folding back from a first end of the exposed portion on the inlet side, sandwiched between an outer peripheral surface of the inlet fitting and an inner peripheral surface of the cover, and comes into contact with the outer peripheral surface of the inlet fitting. 2 . The refueling port according to claim 1 , wherein a front end of the insertion portion of the ground fitting comes into contact with the outer peripheral surface of the inlet fitting in an urged state. 3 . The refueling port according to claim 2 , wherein the insertion portion of the ground fitting is a leaf spring, and the front end of the insertion portion of the ground fitting is formed by bending, and comes into contact with the outer peripheral surface of the inlet fitting in an urged state due to elastic deformation of the leaf spring. 4 . The refueling port according to claim 1 , wherein an outer peripheral surface of the refueling port main body is equipped with an exterior portion on which a pipe with a long shape for circulating fuel is exteriorized, and a second end on an outlet side of the exposed portion of the ground fitting is arranged in a state of facing the outer peripheral surface of the exterior portion and being in contact with an outer peripheral surface of the pipe. 5 . The refueling port according to claim 4 , wherein the exposed portion of the ground fitting is a leaf spring, an intermediate portion of the exposed portion is supported by the outer peripheral surface of the refueling port main body, the exposed portion is elastically deformable with the intermediate portion as a fulcrum due to the elastic deformation of the leaf spring, and the second end of the exposed portion comes into contact with the outer peripheral surface of the pipe that is inserted between the second end and the exterior portion of the refueling port main body in an urged state. 6 . The refueling port according to claim 5 , wherein the intermediate portion of the exposed portion of the ground fitting is formed by bending in a manner that a formed angle is an obtuse angle, and a portion formed by bending is supported by the outer peripheral surface of the refueling port main body. 7 . The refueling port according to claim 1 , wherein the inlet fitting has a groove on the outer peripheral surface of the inlet fitting, and the cover has an internal protrusion that engages with the groove of the inlet fitting in a tubular axial direction of the inlet fitting. 8 . The refueling port according to claim 7 , wherein the internal protrusion of the cover extends in a circumferential direction of the cover and has a notch at an intermediate position in the circumferential direction, and the insertion portion is arranged in the notch. 9 . The refueling port according to claim 1 , wherein the refueling port main body and the cover are molded of a non-conductive resin.
