Claim 0:
1. An endoscope comprising:
an operation section provided with an erecting operating member comprising a lever;
an insertion section that is provided on a distal end side of the operation section and that is inserted into a subject;
a treatment tool erecting base provided at a distal end part of the insertion section;
a movable member, comprising a beam, that is arranged to be exposed to outside of the operation section and that moves in association with an operation of the erecting operating member;
an erecting operation mechanism, coupling the lever and the movable member to each other, such that the movable member moves in response to the operation of the erecting operation member via the erecting operation mechanism transmitting a movement of the lever to a movement of the movable member;
a proximal end opening provided in the operation section;
a distal end opening provided in the distal end part;
an erecting operation wire channel that is provided in the insertion section and that causes the proximal end opening to communicate with the distal end opening;
an erecting operation wire that is inserted through the erecting operation wire channel, the erecting operation wire is coupled to the treatment tool erecting base at a distal end side of the erecting operation wire, a proximal end side of the erecting operation wire coupled to the movable member, and the erecting operation wire is pushed/pulled in accordance with a movement of the movable member to move the treatment tool erecting base; and
an attachment member, comprising a plate, that is provided at a proximal end of the erecting operation wire. and the attachment member is engaged with the movable member in an attachable/detachable manner by a one-touch operation,
wherein the erecting operation wire has a wire exposure region that is exposed to outside from the proximal end opening, and
wherein at least a surface of the wire exposure region is configured of a first insulator,
wherein the erecting operating member is disposed away from the movable member such that the erecting operating member and the movable member are distanced from each other in a longitudinal direction of the operation section.
