<P>PROBLEM TO BE SOLVED: To provide a syringe outer cylinder which is hardly breakable even when high viscosity liquid is injected under high pressure. <P>SOLUTION: Breakage of the syringe outer cylinder can be prevented by setting a reinforcing rib with a concentric circle shape reinforcing part and a radial reinforcing part on the back face of a flange of the syringe outer cylinder, or doubling the flange, or setting a thick wall part on the root part of the flange front face, or setting a tapered reinforcing part on the flange front face. <P>COPYRIGHT: (C)2010,JPO&INPIT |
