By lifting the piston 13, the repair material 63 in the repair material reservoir is injected into the injection cylinder 12. When the repair material 63 is injected, the pressure rubbers 124 and 124 ′ do not hang downward as shown in the figure and remain in the lateral direction, and the repair material 63 adheres and becomes dirty during the operation. There is nothing.

  The shapes of the pressure rubbers 124 and 124 ′ and the pressure rubber attachment hook 122 are devised so as not to face downward. That is, the shape of the pressure rubber mounting hook 122 is such that the thickness direction of the pressure rubbers 124 and 124 ′ can finally enter at the entrance, and inside the pressure rubber 124 and 124 ′. An elliptical shape with the same width is desirable. By devising the shape of the inlet and the inside of the pressure rubber mounting hook 122, as shown in FIG. 10, it does not hang down while the repair material 63 is being injected.

  FIG. 11 is a diagram for explaining a case in which repairing materials are simultaneously put into cracks at a plurality of locations using a plurality of crack repairing material injectors in the conventional example. In FIG. 11, the plurality of crack repair material injectors 12 containing repair materials are arranged along the cracks 62 via the injection washer 14. Since the crack repair material injector 12 is provided perpendicular to the wall surface, the work space is not only narrowed in a narrow place, but it may interfere with the work of the worker.
