PROBLEM TO BE SOLVED: To provide a repairing agent injector that makes it possible to easily measure the amount of a repairing agent introduced and to easily check the progress of injection of the repairing agent, whether or not the injection of the repairing agent is completed, and the remaining amount of the repairing agent to be injected, thus eliminating problems with construction. SOLUTION: The repairing agent injector comprises: an approximately doughnut-shaped cover having a cylindrical recess part formed in its center and an upright injecting part provided at the center of the recess part, with the inside of the cover being hollowed out in the shape of a dome and with a fitting part formed on the bottom surface of its outer periphery; a bottom lid having first and second outer protrusions provided on its outer peripheral surface to form an outer groove and having first and second inner protrusions provided on its inner peripheral surface to form an inner groove, with a center hole bored in its center and holes bored on both sides of the center hole, the bottom lid being mounted on the lower surface of the cover; an elastic sheet having outer protrusions formed on its outer peripheral surface and an inner protrusion formed in its center, the elastic sheet being mounted on the bottom lid with the outer protrusions fitted into the outer groove; and a columnar gauge having a hollow part inside and secured on the elastic sheet, the gauge being passed into a spring and having graduations provided on its outer peripheral surface.
