US Patent 10165930 Endoscope

The endoscope includes: a rotating shaft in a distal end portion body of an insertion portion; an elevator which is coupled with one end of the rotating shaft; an elevator erecting lever which is coupled with the other end; an operating wire which rotates the rotating shaft through the elevator erecting lever to erect the elevator; a partition wall including a holding hole to support the rotating shaft; and a seal member disposed between the holding hole and the rotating shaft. The configuration of the rotating shaft and a positional relation between the rotating shaft and the seal member are improved so as to reduce time and labor taken for cleaning processing of the endoscope.
