A button body (10) of an open-faced button includes an ornamental face disk (13) rotatably supported on a cylindrical retainer (14) firmly fitted in the tubular stem (15) of a button back (12). The retainer (14) has an axial hole (33) for receiving the shank (48) of a tack (11), and a radial groove (32) extending transversely across the axial hole (33). The radial groove (32) and the axial hole (33) is separated by a locking step (34) extending perpendicular to the longitudinal axis of the retainer (14). When the shank (48) is staked into the retainer (14) to attach the button body (10) to a garment fabric (F), a front end of the shank (48) is deformed into an axially compressed and radially swelled end portion (48a) and held in interlocking engagement with the locking step (34) of the retainer (14). |
