A barrel mechanism comprises, with a casing, a rotatable shaft mounted in two bearings supported respectively by two ends of the casing perpendicular to the axis of the shaft, and to which is fixed a plate oblique with respect to the axis, a barrel bearing on the oblique plate, centred about an axis, intersecting the axis of the shaft, on an inclined cylindrical bearing on the shaft and perpendicular to the plate, and a means locking the barrel against rotation, wherein the two ends of the casing are connected by a tie-rod extending along the axis of the shaft in an axial bore in the shaft. |
