<p><P>PROBLEM TO BE SOLVED: To improve the insertion operability of an endoscope by reducing the diameter of the distal end thereof while attaining various kinds of observation form. <P>SOLUTION: The distal end surface of the distal end cover 24 of the distal end 15 is formed biased in one direction of a direction of a Y-axis crossing a center axis O to increase the diameter. A nozzle 60 for sending air and water and two observation lenses 31a and 31b are arranged linearly in order in the biasing direction to wash both of the observation lenses 31a and 31b with the single nozzle 60. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
