A bearing (20) is arranged for an output drive axle (16) and which is comprised in a drive assembly (17). It is also adapted to function as a rotation bearing for the rotatable element (2) as a consequence of the latter being supported relative to the frame (1) via the output drive axle (16). A member (18) supports the drive assembly (17) relative to the frame and preventing the body (19) of the drive assembly to rotate relative to the frame (1) and is arranged to allow some relative movement, comprising some angular motion, between the body and the frame. Mutually engaging members (21,22) of the body and frame respectively, are provided and are designed as recesses and projections respectively engaging with each other. |
