A distal opening (33) is formed at the terminal of the tube (31). Retaining parts (32a, 32b, 32c, 32d), which retain the insertion auxiliary tool (36), are inserted in the tube (31) in the vicinity of the opening (33). The retaining parts (32a, 32b, 32c, 32d) have a cylindrical structure provided with inner wall surfaces (37a, 37b, 37c, 37d), both ends of which open in the axial direction of the tube, that guide and retain the insertion auxiliary tool (36).</p> |
