Abstract
A plastic button having a tiltable button cap (1) with a rotationally symmetrical bottom part (3) that can be riveted to a carrier cloth (5) by means of a tack (6). To provide a permanent connection between button cap (1) and bottom part (3) even under frequent tilting motions, there is formed on button cap (1) a hollow shank (2) that terminates at its lower end in an inwardly projecting annular flange (8). The bottom part (3) made separate therefrom has, at is upper end, a conically tapering collar (10) which can be driven into hollow shank (2), with elastic expansion of annular flange (8), and which, in the joined together state, engages with its shoulders (11) behind the annular flnage (8).
