Claims

[Scope of utility model registration request]

In an endoscope, the air supply and liquid supply are provided in an endoscope having a cloud connecting the distal end component to the distal end of the flexible tube section via a curved tube section, and a conduit for the air supply and liquid supply thread through the inside thereof. An air/liquid feeding device for an endoscope, wherein the liquid thread conduit has an inner diameter larger at a portion within the flexible tube portion than at a portion within the curved tube portion.
