ENDOSCOPIC APPARATUS

PROBLEM TO BE SOLVED: To provide an endoscopic apparatus enhanced in the visibility of the leading end of an arm part when treatment is performed while suppressing the lowering of the inserting properties of an insertion part. SOLUTION: The endoscopic apparatus is equipped with the long tubular insertion part 3, a plurality of the arm parts 5A and 5B provided to the leading end part of the insertion part to protrude forward and made treatable by internally inserted treatment appliances 8A and 8B, the observation body 14 arranged to the leading end part of the insertion part so as to be made separable from the insertion part, an energizing member 43 for energizing the observation body arranged to the leading end part of the insertion part toward the region opposite to a plurality of the arm parts in the diametric direction of the observation body, and a holding mechanism 15 which holds the observation body to the state arranged to the leading end part of the insertion part against the energizing member and releases the holding of the observation body.
