PROBLEM TO BE SOLVED: To provide an endoscope equipped with a treatment tool raising stand which prevents a treatment tool placed on a treatment tool support groove from dropping sideways even when an axis line of the treatment tool is tilted against an axis line of a treatment tool insertion pipeline even though having a structure provided with the raising stand where the treatment tool support groove, in which its opposite side surface side is open, is formed on the side surface opposite to a bottom surface of a recessed part for storing the raising stand.SOLUTION: An endoscope equipped with a treatment tool raising stand includes: a recessed part 28 recessed in the vicinity part of a leading end of an insertion part 12 a treatment tool insertion pipeline 26 for inserting a treatment tool A a raising stand 30 rotatable around a rotary shaft 25 a treatment tool support groove 34 where a cross section formed on the raising stand has a V shape and the treatment tool is engageable a sideway gap 29 which is offset sideways with respect to the treatment tool insertion pipeline and an operation wire 40, in which a leading end is connected to the raising stand and the vicinity part of the leading end is positioned in the sideway gap, and which rotates the raising stand by moving back and forth in response to operation of an operation means provided for an operation part 11. One side part of the raising stand is provided with a sideway support part 37 which is positioned on the opposite side to the bottom surface of the recessed part across the operation wire and has the side parts of the treatment tool support groove formed on the opposite side surface.COPYRIGHT: (C)2013,JPO&INPIT【課題】起上台を収納する凹部の底面と反対側面に該反対側面側が開放した処置具支持溝が形成された起上台を具備する構造でありながら、処置具の軸線が処置具挿通用管路の軸線に対して傾斜している場合においても処置具支持溝に載った処置具が側方に脱落するのを抑制できる処置具用起上台を備える内視鏡を提供する。【解決手段】挿入部12の先端近傍部に凹設した凹部28と、処置具Aを挿通可能な処置具挿通用管路26と、回転軸25回りに回転可能な起上台30と、起上台に形成した断面がV字形をなし、処置具が係合可能な処置具支持溝34と、処置具挿通用管路に対して側方にオフセットする側方隙間29と、先端が起上台に接続しかつ先端
