<p>The main support (1) can be immobilized relative to a case (2) and comprises a first cylindrical unit (A) defining a reception volume for either a component fixed to the shaft (8) or to another cylindrical unit (B). The first unit is formed from a sleeve (4) able to slide axially in a bore (13) and a collar (5) fitted with a lug (52) snapping into the sleeve. The lug has a rack (52b) able to mesh with a support relief (12b,12'b) to translationally immobilize the first unit in the bore.</p> |
