Abstract: The cover removal tool of the endoscope includes an enclosure, which is a fit hole that is fitted to cover the distal end cover having a locking portion and mounted on the distal end assembly, which is provided at the tip of the insertion section. The cover removal tool is provided with a protrusion that protrudes inside the enclosure. When the cover removal tool is fitted with the distal end cover being into contact with its interior, the protrusion comes into contact with part of the edge of the opening of the distal end cover and pushes in the peripheral direction. As the edge of the opening is pressed while being twisted, the distal end cover is broken by plastic deformation, and the lock with the locking portion is thereby released.
