The output reduction stage (7) comprises a driving sun gear (8) which rotates about a main axis (A) and a ring gear (9) which is integrally associated with the substantially box-like body (2), between which multiple planet gears (10) are engaged which are supported in rotation about respective longitudinal axes which are parallel to the main axis (A) by a transmission planet carrier (11), which in turn rotates about the main axis and is associated so as to be integral in rotation with the transmission shaft (5) at a connection region (12). The reduction unit (1) furthermore provides for rolling means (14) adapted to support radial loads associated with the transmission shaft (5) for the rotational guiding thereof. The rolling means (14) comprise a first radial bearing (15) which is interposed in a radial direction between the substantially box-like body (2) and the planet carrier (11) and a second radial bearing (16) which is interposed radially between the body and the transmission shaft (5), the first and second bearings (15, 16) being arranged axially on opposite sides of the connection region (12).
