PROBLEM TO BE SOLVED: To provide a drip-proof connection mechanism with good workability and assemblability of a member by increasing the degree of freedom in design of the drip-proof connection mechanism.SOLUTION: A drip-proof connection structure includes: a shaft body having a cylindrical surface; a box body formed with an opening through which the shaft body is passed; an annular member placed over the cylindrical surface; a first cutoff body placed over the cylindrical surface, and sandwiched between the cylindrical surface and the annular member; and a second cutoff body placed over an outer peripheral surface of the annular member, and brought into close contact with the annular member and the box body.SELECTED DRAWING: Figure 7 |
