A floating connector that absorbs positional misalignment of a counter connector when the counter connector is fitted along a fitting axis (F), the floating connector comprising: a base portion including a surface which extends along an XY plane, the base portion further including an opening portion whose center is the fitting axis (F) which extends perpendicularly to the surface ; a pair of contact portions that come into contact with the counter connector, the floating connector being characterized by the contact portions being arranged in parallel to the surface of the base portion ; and by comprising an arm portion that connects the base portion to the contact portion, wherein a direction perpendicular to the surface and extending from the base portion toward the arm portion is defined as "+Z direction", and a direction opposite to the +Z direction is defined as "-Z direction", wherein the arm portion includes a root portion extending from a -Y directional end of the base portion, the root portion including an elastically deformable portion extending from the base portion in the +Z direction parallel to the fitting axis, the root portion then bending towards the -Z-direction, wherein the arm portion further comprises a pair of branched portions extending from a +Y directional end of the root portion ; wherein tip ends of the arm portion extend in a direction intersecting the fitting axis, wherein the contact portions are formed at the tip ends of the branched portions of the arm portion, the contact portions being arranged so as to face each other across the fitting axis (F) that passes the center of the opening portion , and wherein the elastically deformable portion twists and deforms having the elastically deformable portion itself as a center, whereby the contact portion is floated in an arcuate motion within a plane perpendicular to the fitting axis (F) which is parallel to the XY plane. a base portion including a surface which extends along an XY plane, the base portion further including an opening portion whose center is the fitting axis (F) which extends perpendicularly to the surface ; a pair of contact portions that come into contact with the counter connector, the floating connector being characterized by the contact portions being arranged in parallel to the surface of the base portion ; and by comprising an arm portion that connects the base portion to the contact portion, wherein a direction perpendicular to the surface and extending from the base portion toward the arm portion is defined as "+Z direction", and a direction opposite to the +Z direction is defined as "-Z direction", wherein the arm portion includes a root portion extending from a -Y directional end of the base portion, the root portion including an elastically deformable portion extending from the base portion in the +Z direction parallel to the fitting axis, the root portion then bending towards the -Z-direction, wherein the arm portion further comprises a pair of branched portions extending from a +Y directional end of the root portion ; wherein tip ends of the arm portion extend in a direction intersecting the fitting axis, wherein the contact portions are formed at the tip ends of the branched portions of the arm portion, the contact portions being arranged so as to face each other across the fitting axis (F) that passes the center of the opening portion , and wherein the elastically deformable portion twists and deforms having the elastically deformable portion itself as a center, whereby the contact portion is floated in an arcuate motion within a plane perpendicular to the fitting axis (F) which is parallel to the XY plane. <EOS>
