PROBLEM TO BE SOLVED: To provide a rail member and a mounting structure of a rail member which can be mounted easily and in good appearance with respect to an existing upper frame material in which a wide recess groove according to the existing rail member is provided.SOLUTION: At a rail member 1 which is mounted so as to be embedded in a recess groove 3 of an existing upper frame material 2 from which an existing rail member has been removed, a guide groove 10 is provided which opens downward and which has a groove width dimension W3 which is smaller than a guide groove opening downward and provided at the existing rail member. The rail member includes: a pair of flange-like piece parts 16, 16 protruding respectively to the outside in a groove width direction from a lower end part of both side wall parts 14, 14 for partitioning the guide groove, and coming into contact with a lower surface of the upper frame material so as to cover each opening edge on both sides in the groove width direction of the recess groove; and a pair of contact piece parts 18, 18 protruding respectively to the outside in the groove width direction from the position at an interval on the upper side of the pair of flange-like piece parts on both side wall parts, and coming into contact with each inner side surface on both sides in the groove width direction of the recess groove.SELECTED DRAWING: Figure 1 |
