PROBLEM TO BE SOLVED: To force-feed a filler with a high pressure by hardly allowing a suction block to be separated from a wall surface even if a moment is caused on an arm. SOLUTION: This device S for repairing a crack in a wall comprises: an injection nozzle 10, the leading end of which is arranged in the crack 2 in the wall and which injects the filler into the crack 2; the sucker 20 attached to the wall surface by suction and detached from the wall surface by relieving the suction; and an arm 30 which is provided on the sucker 20 and the leading end 31 of which is fitted with the injection nozzle 10. An intermediate portion 32 of the arm 30 is supported on the sucker 20 in such a manner as to be orthogonal to a central axis 34 through the intermediate portion 32, and through the leading end portion 31, intermediate portion 32 and back end portion 33 of the arm, and to be rotatable on a horizontal axis 35 parallel to the wall surface 1. An abutting member 40, the leading end of which abuts on the wall and which bears a moment load occurring in the arm 30 when the filler is infilled by means of the injection nozzle 10, is attached to the back end portion 33 of the arm 30.
