Abstract
A removal tool for removing a hood having a hollow cylindrical shape mounted to a distal tip of an endoscope from the distal tip is constituted from a flexible member including a hole-shaped recess capable of housing the hood in its inside. An outer surface of the hood is provided with a step portion that extends along a circumferential direction of the hood. An inner wall surface of the recess is provided with an engaging portion at a position opposing to the step portion when the hood is housed in the recess, the engaging portion being shaped to grip the hood by being engaged with the step portion as a result of deformation of the flexible member.
