PURPOSE: An injector for repairing a crack in a concrete structure is provided to pack/carry simply by minimizing the volume and to reduce the required costs for repair works. CONSTITUTION: The injector for repairing a crack in a concrete structure comprises: a fixed plate(10) provided with a through hole(11) attached on a plane and a pressure projection formed longitudinally in the through hole(11); a coupling cap(20) provided with a projected injection opening(21) to couple with the through hole(11) of the fixed plate(10); a check valve(30) installed to the injection opening(21) to control the access of a repair agent; a container(60) coupled to an opening of the coupling cap(20) and expanded longitudinally according to the access of a repair agent; and an elastic pressurizer formed in an elastic ring shape, provided with a perforation hole to interpose an injection opening of the coupling cap, coupled to the coupling cap and the container, and supported elastically in the compressed direction.
