Claim:
A self-orienting caster for pieces of furniture, comprising at least one wheel which is supported so that it can rotate about a horizontal axis by a supporting structure which has a vertical cylindrical recess which is open upward and is axially offset with respect to said horizontal axis and constitutes a seat in which a pivot for the pivoting of the caster can rotate, said pivot being insertable in a receptacle of the piece of furniture onto which the caster is to be fitted, said supporting structure comprising two mutually opposite annular flanges, which form respective circular holes that are coaxial to said horizontal axis, the caster further comprising a tubular body coaxial to said circular holes and to said horizontal axis and having opposite ends which are rigidly coupled to inner edges of said holes, said tubular body forming externally, between said flanges, a rolling track for a supporting bearing on which said at least one wheel is rotatably supported, respective extensions being monolithically rigidly coupled to said flanges and comprising respective wings that protrude from said flanges and that are mutually associable so as to provide a closed supporting structure that forms said seat which is designed to receive said pivot for the pivoting of the wheel.
