The present invention relates to a rotary member with interchangeable attached peripheral elements, such as a toothed wheel, pinion, cam, etc., solidly attached to a rotating drive shaft, comprising a hub solidly attached to a transverse circular flange of greater diameter than the hub and to which flange the interchangeable peripheral elements are fixed in a removable manner. This rotary member is characterised in that the transverse flange 5 carries retention means 7 projecting in the longitudinal direction and centred on the axis of the hub 1, and each interchangeable element 2, 3 in the shape of an annular segment has, on one of its front faces 2a, 3a, at least one hollowed portion 8 in which the retention means 7 carried by the transverse flange 5 tightly engage. <IMAGE>
