PROBLEM TO BE SOLVED: To provide an injector of an adhesive into cracks, which is improved in fixing strength of a mount to be fixed to an external surface of an injection objective body, makes a cylinder thereof repeatedly usable, and is free from degradation of the strength of the cylinder. SOLUTION: According to the structure of the injector of the adhesive into cracks, the tip of the cylinder 24 is fixed to the mount 22 to be mounted on the injection objective body b of the adhesive, and a piston shaft 29 is arranged in a piston 25 inserted into the cylinder 24 in an axially movable manner, followed by setting an injection plug 35 with a check valve at a rear edge of the piston shaft 29 protruding outward from a rear edge of the cylinder 24. Then the piston 25 is energized by applying forward movable elasticity by an elastic body. Further the mount 22 has a circular protrusion 30 formed on one surface thereof opposite to a surface to be mounted on the injection objective body b, in order that the tip of the cylinder 24 is fastened and fitted onto the circular portion. The circular protrusion 30 has an inner diameter equal to or larger than that of the cylinder 24. Further the circular protrusion 30 has a through-hole 31 axially formed at the center thereof, and the tip of the cylinder 24 is formed like a cylinder having the inner diameter sufficient for fitting onto the circular protrusion 30.
