Claim:
An articulation device applicable to an awning arm elbow, of the type comprising: a first elbow part fixed to an end of a first semi-arm, said first elbow part defining a fork having branches between which a shaft is supported; a second elbow part fixed to an end of a second semi-arm, said second elbow part defining a core adapted to be arranged between the branches of said fork and provided with an axial hole into which said shaft is inserted, an anchoring configuration being formed in an outer surface of said core for hooking an enlarged end of a flexible tie rod element connected to an elastic member accommodated inside said first semi-arm; and bearing means arranged between the core and the shaft in the mouths of said axial hole to guide a relative rotation between said first elbow part and said second elbow part around said shaft and to support one of the first or second semi-arms on the other; wherein said bearing means include at least one bearing unit comprising at least one annular element fixed in a seat formed in the core in one of the mouths of the axial hole, wherein said seat comprises a conical radial support surface coaxial with the shaft, an axial support surface perpendicular to the shaft, and a circumferential channel formed in said axial support surface adjacent to said conical radial support surface, and wherein said annular element of the bearing unit comprises a cylindrical outer radial rest surface, adapted to be fitted, by pressurized insertion with interference, into said conical radial support surface of the seat, and an axial rest surface adapted to rest against said axial support surface of the seat.
