Abstract
A nut (30) carried by a nut holder (11) is inserted into a dovetail groove (46) in a profile frame (45) to connect another profile frame or a mechanical component to the profile frame (45). The nut holder (11) has clamping portions (19A, 19B) at both longitudinal ends that extend in one direction at approximately right angles to a bottom member. Coupling projections (23) or recesses are formed on the inner sides of the clamping portions (19A, 19B). Elastically deformable portions (13) project from the sides of the bottom member. Abutments (34) are formed at both ends of the nut (30). When the nut (30) is coupled to the nut holder (11), the coupling projections (23) are engaged with the coupling recesses (34) to maintain the coupled state. When the nut (30) coupled to the nut holder (11) is inserted into the dovetail groove (46), the nut is maintained at a predetermined position in the groove by frictional force due to resilient force from the elastically deformable portions (13).
