Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent air from flowing into a cylinder at the time of sucking an adhesive by projectingly providing a projecting part having the shape corresponding to the space shape to the inside of a nozzle on the tip surface of a plunger. SOLUTION: An injection pipe 12 is fixed on a crack 14 caused on a concrete- made wall surface 11 with an adhesive 13, and an injector 1 is attached to the injection pipe 12. A rubber ring 15 is engaged between a restraining part 8 projecting at the tip part of the cylinder and a part projecting at the rear tip part of the plunger 3, and the plunger 3 is advanced by using the contraction force of the rubber and the adhesive is injected and filled in a crack 14 under low pressure by the injector 1. At this time, the projecting part 7 having the shape corresponding to the space shape at the inside of the nozzle 4 is provided at the tip part of the plunger 3. In this way, the air hardly flows into the cylinder 2 at the time of sucking the adhesive 10, and a sure reinforcing effect is expected.
