The invention provides a screw pitch feedback device, and belongs to the technical field of ship equipment. The screw pitch feedback device comprises a feedback rod, a transmission ring assembly, a detection rod and a clearance compensation assembly; the transmission ring assembly is coaxially sleeved outside a rotating shaft tube of a propeller, the feedback rod and the detection rod are respectively located at two ends of the transmission ring assembly, the feedback rod is hinged with the transmission ring assembly through a first hinge shaft, the detection rod is hinged with the transmission ring assembly through a second hinge shaft, and the feedback rod is connected with the detection rod. The clearance compensation assembly is connected with the detection rod and used for applying pressure to the detection rod so as to limit the transmission ring assembly and the detection rod from moving relative to the second hinge shaft and limit the transmission ring assembly and the feedback rod from moving relative to the first hinge shaft. And the direction of the pressure is the same as or opposite to the translation direction of the detection rod. The detection precision of the pitch position of the propeller can be improved.
