Description of the Related Art In a side view type endoscope, a treatment instrument raising piece for changing a projecting direction of a distal end portion of a treatment instrument inserted through a treatment instrument insertion channel is generally provided at a distal end of an insertion portion. The treatment instrument is rotatably supported by a support shaft in the main body, and is driven by an operation wire operated to advance and retreat from the operation section, so that the direction of projection of the treatment instrument can be changed.
