Abstract:
1. A clip assembled to an upper surface portion of a pedestal portion provided on one surface of an attachment member and used to attach the attachment member to an attachment receiving member, wherein the pedestal portion comprises a horizontally long cutaway groove portion protruded into a substantially square-bracket-like shape opened downward when seen from a side view and formed inward from a side surface portion at one side of an upper wall, the attachment member comprises a pair of positioning boss portions provided in an upright posture outside opposite side wall portions of the pedestal portion and formed with a plurality of positioning grooves on its upper end surface portion formed successively in a direction at a substantially right angle relative to a longitudinal direction of the cutaway groove portion, wherein the clip comprising: a flat plate portion to be brought into contact with an upper surface portion of the upper wall; a boss portion extended vertically downward from a bottom surface of the flat plate portion and has a width substantially equal to a width of the cutaway groove portion, and is fitted to the cutaway groove portion; a flange portion having a predetermined thickness and extended from a lower end portion of the boss portion outward to the opposite sides of the cutaway groove portion so as to be brought into contact with a bottom surface portion of the upper wall; a fitting head portion having a substantially square shape when seen from top, provided in an upright posture on an upper surface of the flat plate portion and fitted to a first long hole penetratively formed in the attachment receiving member along a direction at a substantially right angle relative to a longitudinal direction of the cutaway groove portion; a pair of elastic locking pieces elastically deformable in an insertion direction of the fitting head portion, the elastic locking pieces provided on opposite side surface portions of the fitting head portion in a longitudinal direction of the cutaway groove portion, and each being formed with a locking protrusion in an upright posture outward from its lower end to a predetermined height; and a flat plate-like seat plate member formed with a second long hole having a width substantially equal to a width of the fitting head portion in a direction at a substantially right angle relative to a longitudinal direction of the cutaway groove portion, and the fitting head portion being fittingly inserted into the second long hole so as to be brought into contact with the upper surface of the flat plate portion; a pair of positioning locking pieces elastically deformable in the vertical direction, each having a protruded positioning rib to be fitted to one of the positioning grooves on a lower surface of a top end of each position locking piece, and extended outward from both end edges in the longitudinal direction of the second hole of the seat plate member, wherein, as the fitting head portion is fitted to the first long hole penetratively formed in the attachment receiving member, the boss portion moves within the cutaway groove portion to bring the seat plate member into contact with the attachment receiving member and to elastically lock the pair of elastic locking pieces with a periphery of each longer side portion of the first long hole, and when an upper end surface of the seat plate member is brought into contact with the attachment receiving member, the positioning locking piece is depressed by the attachment receiving member to be in substantially flush with an upper end surface of the seat plate member, and at the same time, the positioning rib portion is fitted to the opposing one positioning groove portion.
