する内視鏡装置。[Claims for Utility Model Registration] The objective optical system provided at the tip of the insertion section inserted into the object to be observed, the objective side end of the image guide, the eyepiece side end of the image guide, and the imaging optical system are connected to the optical axis. In an endoscope device, an air supply tube and a water supply tube extending inside the insertion section are connected to a nozzle provided at the distal end of the insertion section so as to vibrate relative to each other in synchronization with the direction substantially orthogonal to the above. A tube for air supply and a tube for water supply are integrated into one tube so as to join within a rigid distal end portion at the distal end of the insertion section, and a piezoelectric drive element is provided on an extension line of one of the tubes in the direction of the distal end of the insertion section. Endoscope equipment.
