The fan rotor has slots (13) formed in periphery of a disc (15), to receive root (21) of blade (20) attached to the rotor, and elongated spacer (11) of elastically deformable material arranged between blade root and bottom (13a) of slot. The spacer has longitudinal segments (17b) having a transverse profile of arcuate shape to form lateral zones (25a,25b) that contact corresponding lateral zones (26a,26b) of the blade root. The spacer segment has central zone (29) spaced apart from corresponding central zone (30) of the bottom of the slot. |
