  The balloon 31 is inflated only when the inside of the endoscope duct 20 is cleaned and disinfected. This is because, when the balloon 31 is inflated during cleaning and disinfection of the outer surface of the endoscope 10, the cleaning liquid or the disinfecting liquid does not enter the downstream side of the balloon 31, and the insertion portion on the downstream side of the balloon 31. This is because the cleaning liquid or the disinfecting liquid cannot be supplied to the outer peripheral surface on the distal end side in the insertion direction S. Although not shown, an electromagnetic valve for storing the disinfectant solution in the fitting member 30 is provided at a site downstream of the bottom surface 159ht of the recess 159h of the drainage pipe 159 when disinfecting.

  Furthermore, since the balloon 31 is provided on the fitting member 30 that is detachable with respect to the concave portion 159h, it can be easily exchanged by attaching / detaching the fixing ring 45 even if it is necessary to exchange it due to deterioration or the like. it can. The fitting member 30 itself may be replaced as the balloon 31 deteriorates.

  Thus, even if the backflow preventing member is formed of a balloon, the same effect as in the above-described embodiment can be obtained.
