The invention relates to a fan module (1) having variable-pitch blades for a propulsion unit having a longitudinal axis (X), comprising: - a rotary casing (3) carrying the blades (5); - a pitch-changing system (22) comprising a control device (23) including an annular actuator having a stationary body (25) added onto the rotary casing and a body (27) capable of translating with respect to the stationary body along the longitudinal axis, and a linking mechanism (24) including a synchronising ring (34) coupled to the mobile body, connected to the blades (5) and configured to be translated along the longitudinal axis (X) by the mobile body so as to change the pitch of the blades; and - a feathering device (38) comprising fly-weights (43) coupled to the ring by a connecting rod of which the ends include ball-and-socket joints (62, 63).
