<P>PROBLEM TO BE SOLVED: To provide a low pressure injector having structure of sufficiently liquid-tightly fixing a body plate and an elastic sheet without being constrained by a material of the body plate or the elastic sheet. <P>SOLUTION: A body plate 1 to be attached to a wall surface 3 in the state of liquid-tightly closing an opening of a crack 31 is provided with a fixing hole 12, and an elastic sheet 2 includes a main part 21 and a part 22 to be fixed and is fixed to the body plate 1 by fitting the part 22 to be fitted to the fixing hole 12. The main part 21 is elastic and is swollen by a pressure when a filler 4 is injected, and when it returns to an original shape by resilience, the filler 4 is pushed into the crack 31 and filled. The plate body 1 is formed of a metal which is plastically deformable according to the shape of the wall surface 3, and the elastic sheet 2 is made of synthetic rubber such as silicone rubber. <P>COPYRIGHT: (C)2012,JPO&INPIT |
