Abstract
A guide tube which stabilizes a guide position of a scope inserted into an object to be observed and serves to prevent a surface wall portion of the object to be observed from being pinched by a leading end. A metal ring and a hard plastic ring having a ring like convex portion are attached to a leading end of a main tube of the guide tube. The ring like convex portion is made, for example, of an elastic polyurethane resin and a protruding end has an inside diameter D1 which is slightly smaller than an outside diameter of a scope to be guided. The guide tube is capable of bringing the scope into close contact with an inside of the convex portion. Furthermore, the metal ring makes it possible to confirm a location of the guide tube by x-ray radioscopy inspection.
