Abstract
An assembly of parts assembled with one another by a shaft passing through orifices formed in the parts is disclosed. The shaft has a base diameter (DB) and a thickened diameter (DE) over diametrically opposed arcs at two different sections. The orifices are aligned with one another and each have a periphery having a first diameter (D1) on first diametrically opposed portions, the first diameter (D1) corresponding to the thickened diameter (DE), and a second diameter (D2), greater than the first diameter (D1), on second portions of the periphery. This allows the shaft to be fitted easily even when the orifices are only approximately aligned, and also makes removal easier.
