The invention relates to a device (5) for absorbing vibrations, intended for a motor vehicle transmission, having an axis of rotation X and comprising: i. a mounting (10) defining two radially external supporting raceways (431, 432) and one radially internal supporting raceway (37); ii. a counterweight (16) defining a radially internal counterweight raceway (73) and two radially external counterweight raceways (701, 702); iii. two external rolling bodies (191, 192) mounted such as to be able to roll and/or slide on at least one of the radially external supporting (431, 432) and counterweight (701, 702) raceways and an internal rolling body (22) mounted such as to be able to roll and/or slide on at least one of the radially internal supporting (37) and counterweight (73) raceways, such that the counterweight can oscillate freely on the mounting. The mounting comprises a window (25) that passes through the mounting along the body thereof, the counterweight being, regardless of the position thereof, contained in the virtual enclosure having prismatic axis Y, parallel to the X axis, resting on the contour (26, 76) of the window, and projecting axially from the mounting. |
