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. |
