A rotary damping device (10) includes a housing (12) comprising a radially inner wall (17), a radially outer wall (18) and an end wall (19), which delimit a chamber (16) containing a viscous braking fluid; and a rotor (14), rotationally connected to the housing and mounted thereon on the opposite side to the end wall (19) so as to close the chamber (16). The rotor comprises a braking portion (27) having the form of an annular collar which extends axially inside the chamber (16) and is arranged between the radially inner wall (17) and the radially outer wall (18) of the housing (12). The radially inner wall (17) of the housing (12) has, formed therein, at least one recess (31) facing the braking portion (27) of the rotor (14) and able to interrupt the circular profile of the radially inner wall (17) inside the chamber (16). |
