Claim 7:
8. An endoscope comprising:
a main body portion that has a drive member arrangement space that houses a drive member that swings an elevator that is provided at a distal end of an insertion portion of the endoscope and changes a protruding direction of an instrument, a lid insertion space that puts the drive member arrangement space and an outer space surrounding the insertion portion into communication, and a lid member that can be inserted from the outside space into the lid insertion space, and liquid-tightly closes off the lid insertion space and closes off the drive member arrangement space from the outer space when inserted into the lid insertion space, the lid member being configured to have a protruding portion that protrudes from the lid insertion space into the drive member arrangement space; and
a fitting/holding member that is inserted into the drive member arrangement space, and is fixed inside the drive member arrangement space by sandwiching, along with the lid member, a wall between the drive member arrangement space and an outer space outside the main body portion and being fitted to the protruding portion of the lid member, thus restricting separation of the lid member from the lid insertion space.
