PROBLEM TO BE SOLVED: To provide a residue detector in a fluid feeder surely detecting the residue of a fluid by a simple constitution and having high reliability. SOLUTION: In the fluid feeder feeding a fuild stored in a hopper to the outside through a discharger, agitating the fluid by an agitator as required, the agitator is constituted so that the fluid is agitated by rotating an agitating member by the rotational driving of a hydraulic motor 43 driven by feeding pressure oil from a hydraulic pump P for a hydraulic circuit. In the fluid feeder, a pressure detector 6 detecting the pressure of pressure oil is installed to the hydraulic circuit, and the residue of the fluid is detected on the basis of the detection result of pressure by the pressure detector 6. The pressure detector 6 has at least one pressure switch, and the insufficient residue of the fluid is informed by an information means when reaching to the fixed or lower pressure of pressure oil is detected by the pressure switch.
