Abstract
A distal end part of an endoscope including an end cap provided with a nozzle for spouting a fluid in a predetermined direction. The end cap is detachable with respect to a distal end block which is provided at the distal end of an insert part of the endoscope. Engagement portions are provided on the end cap and the distal end block to regulate the condition in which the end cap is fitted to the distal end block. The engagement portion of the end cap and the engagement portion of the distal end block are formed such that, among different models of endoscopes in which the distal end blocks have approximately the same outer diameter, the engagement portion of the end cap off one model cannot be engaged with the engagement portion of the distal end block of another model.
