PURPOSE: A crack-repairing-liquid injector for a concrete structure is provided to improve productivity and workability, and to be easily produced while a pressurizing projection is united with a deformation plate. CONSTITUTION: A crack-repairing-liquid injector comprises a supporting plate(32), a deformation plate(42), a nozzle(52) and a cover(60). In the supporting plate, a wing frame(30) fit to a concrete structure is prolonged out. A store part(34) is projected out, and a bind hole is formed in the upper end of the store part. An air passage(38) is formed in the lower end of the store part. In the deformation plate, one side of the plate is fixed in the store part, and a bind groove is formed. A pressurizing projection(46) is projected from the bind groove, and a guide hole(48) is formed in the lower end of the bind groove. In the nozzle, the upper end is projected out through the bind hole of the store part, and a lower end is fixed in the bind groove of the deformation plate. A hole(50) for inflow of crack-repairing liquid is formed. In the cover, one side of the cover is fixed in the store part, and a receiving groove(62) is formed. A discharging hole(64) is formed in the receiving groove, and a vertical guide groove(66) is formed between the receiving groove and the discharging hole.
