Abstract: In a wear compensating device (40), a wedge-shaped stem (41) is connectable at one end (48) thereof to a drive (10, 20) and is movable by the drive in an axial direction between a first position, corresponding to an engaged condition of the clutch, and a second position, corresponding to a disengaged condition of the clutch. The wedge-like stem (41) has an outer side surface (49a) and an inner side surface (49b) inclined obliquely with respect to the axial direction (x). A hollow member (42) for acting against clutch operating lever (L) has an axially elongated cavity (45) movably accommodating the wedge-shaped portion (49) of the stem (41) to allow relative axial movements between the stem (41) and the hollow member (42).
