A hinge device comprising a first fixed tubular half-shell (12) including a working chamber (20) defining a longitudinal axis (X), a second tubular half-shell (13) rotatable about the axis (X), a pivot (50) rotating unitary with the latter which includes a single passing-through actuating member (72) having helical shape, a plunger member (30) slidable along the axis (X), and a tubular bushing (80) having a pair of guide cam slots (81). A pin (73) inserted within the passing-through actuating member (72) is provided to allow the mutual engagement of the pivot (50) and the bushing (80). The first tubular half-shell (12) includes an end portion (16) susceptible to rotatably support the pivot (50) , the second tubular half-shell (13) and the bushing (80) are coaxially coupled to each other, the bushing (80) and the first tubular half-shell (12) are mutually unitary coupled. |
