The present invention mainly relates to a rotatary electric machine, comprising a rotor provided with a body having an axis (X), the rotor body comprising a plurality of longitudinal chambers, each chamber being designed to receive at least one permanent magnet; magnetic poles, each being formed by a permanent magnet (13) received in two adjacent chambers forming a V on a plane (P) orthogonal to the axis (X) of the rotor body. The rotor comprises at least one retaining member (35) for retaining a permanent magnet in a chamber (13). The rotor is characterized in that the retaining member (35) comprises two elongated strips (26); each strip (26) comprises at least one protrusion (37) designed to exert a retention force to retain the corresponding permanent magnet (13) in the chamber (16); and the retaining member (35) additionally comprises at least two connecting arms (40) between the two strips, the protrusion (37) extending axially between the two connecting arms.
