PROBLEM TO BE SOLVED: To provide a sealing structure of a lever operation part in which sealing property can be improved.SOLUTION: A lever operation part includes: an operation lever 17, which can be operated to move to a plurality of operation positions along a guide insertion hole 60 formed in an operation panel; and a sealing member 65 that seals the guide insertion hole 60 while allowing the moving operation of the operation lever 17. The sealing member 65 is composed of a plurality of elastically deformable sealing units 65A, 65B having a slit 66 formed therein for allowing the moving operation of the operation lever 17, in such a state that an opening hole 67 is formed at a position corresponding to the operation position in at least one sealing unit and that the plurality of sealing units 65A, 65B are overlapped to dispose the slit 66 of other sealing unit than the sealing unit having the opening hole 67, at the position where the opening hole 67 is located. |
