Another element (4) is mounted on the former element and includes a portion (4b) arranged to form a housing (6) in cylindrical sector shape. A third element (5) is fixed on a sash (1) and arranged such that another portion (5b) slides in rotation relative to the axle in the housing formed between the former element and the latter element. The latter portion includes a profile forming a cylindrical sector centered on the axle, where diameter of the sector is same as that of the housing. |
