[2] Fitting (1) according to claim 1, wherein the first frame element (21) is provided with a guide groove (264) extending along the longitudinal direction, the guide groove (264) being designed to guide a movement of the wing (3), wherein the first pulling mechanism (5) contains: a projection (512,513) provided on the wing (3); and a first receiving element (52) provided on the first frame element (21), wherein the projection (512, 513) is designed to protrude from the wing (3) towards the first frame element (21) to be inserted into the guide groove (264), the first receiving element (52) comprises a first guide surface (523a, 524a) provided in the guide groove, wherein the first guide surface (523a, 524a) is designed to come into contact with the projection (512, 513) to guide the projection (512, 513) towards the one side when the wing (3) is moved into the closed position, and the second pulling mechanism (6) is provided outside the guide groove (264). [3] Fitting (1) according to claim 2, wherein the projection (512, 513) is designed to slide in the guide groove (264) to guide the movement of the wing (3) when the wing (3) is moved to a position other than the closed position; the first receiving element (52) comprises a pulling groove (526) which is designed to communicate with the guide groove (264) in an extension direction of the guide groove (264), and the first guide surface (523a, 524a) corresponds to a side surface of the pull groove (526). [4] Fitting (1) according to one of claims 1 to 3, wherein the second pulling mechanism (6) comprises: a tension member (61) provided on the wing (3); and a second receiving element (62) provided on the first frame element (21), wherein the tension piece (61) comprises a projecting part (612) which is designed to project in a direction opposite to the one side, and the second receiving element (62) comprises a second guide surface (622a) designed to come into contact with the projecting part (612) in order to guide the projecting part (612) towards the one side when the wing (3) is moved into the closed position. [5] Fitting (1) according to claim 4, wherein the first frame element (21) is provided with a rail (26) which is designed to protrude towards a frame element (22) of the frame body (2) facing the first frame element (21), the rail (26) extending along the longitudinal direction, the rail (26) is provided with a guide groove (264) extending along the longitudinal direction, wherein the guide groove (264) is designed to guide a movement of the wing (3), the second receiving part (62) is provided on an outer surface of the rail (26) outside the guide groove (264) and the projecting part (612) is designed to slide on the outer surface when the wing (3) is moved in a position other than the closed position. [6] Fitting (1) according to one of claims 1 to 5, wherein the first frame element (21) and the wing (3) are provided with a play prevention mechanism (7) which restricts movement of the wing towards one side when the wing (3) is positioned at a position other than the closed position, and the backlash prevention mechanism (7) is provided at a position in the depth direction which is different from those of the first pulling mechanism (5) and the second pulling mechanism (6). [7] Fitting (1) according to claim 6, wherein the backlash prevention mechanism (7) comprises: a sliding mechanism (8) provided on the wing (3); and a third receiving element (9) provided on the first frame element (21), wherein the sliding mechanism (8) comprises: a support element (81) fixed to the wing (3); a slider (83) designed to be pivotally mounted relative to the support member (81), the slider (83) being designed to be moved between a sliding position and a non-sliding position by rotation of the slider (83), the sliding position being a position in which the slider (83) comes into contact with the first frame member (21) to restrict movement of the wing (3) toward one side, the non-sliding position being a position in which the slider (83) is away from the first frame member (21); and a preloading element (84) designed to preload the slider (83) into the sliding position, and wherein the third receiving element (9) comprises a third guide surface (921) adapted to come into contact with the slider (83) to rotate the slider (83) into the non-sliding position against a preloading force of the preloading element (84) when the wing (3) is moved into the closed position. [8] Fitting (1) according to claim 7, wherein the first frame element (21) is provided with a rail (26) which is designed to protrude towards a frame element (22) of the frame body (2) facing the first frame element (21), the rail (26) extending along the longitudinal direction, the rail (26) is provided with a guide groove (264) extending along the longitudinal direction, wherein the guide groove (264) is designed to guide a movement of the wing (3), the third receiving element (9) is provided on an outer surface of the rail (26) outside the guide groove (264), the slider (83) is positioned in the sliding position by the preloading element (84) to slide on the outer surface when the wing (3) is moved to a position other than the closed position.
