  9LLI;.R DE -ß.'..),61T. y,..ï OLl.E' BICYCLETTE. 



   La présente invention vise un palier de pédalier qui se distingue par sa douceur et son aptitude à supporter des charges plus fortes que les paliers connus à cônes et à billes. 



   Suivant   l'invention,   le palier de pédalier est muni   d'au   moins un roulement à rouleau. 



   Pour lui permettre de supporter également des charges axiales plus élevées,les supports des roulements à rouleaux sont de préférence de forme conique. 



   La figure   annexée   représente en coupe axiale une   fo@@@@   d'exécution de l'objet de l'invention, indiquée à titre d'exemple.

  9LLI; .R DE -β. '..), 61T. y, .. ï OLl.E 'BICYCLETTE.



   The present invention relates to a bottom bracket bearing which is distinguished by its smoothness and its ability to withstand heavier loads than the known cone and ball bearings.



   According to the invention, the bottom bracket is provided with at least one roller bearing.



   To enable it to also withstand higher axial loads, the supports of the roller bearings are preferably conical in shape.



   The appended figure shows in axial section an embodiment of the object of the invention, indicated by way of example.



   The sleeve 1 of the frame of the bicycle houses the bearing of the crankset, the axle of the crankset 4 journals in the roller bearings 2, 3. The rollers are arranged obliquely with respect to the axle of the crankset. Lids 5
