PROBLEM TO BE SOLVED: To provide a new type for preventing abrasion by long-term use of a rotary shaft 500 (a shaft) and delicate leakage of moisture from a sliding surface 207 of packing, in a mixer having a frame body 20.SOLUTION: In a mixer for mixing an object stored in a predetermined frame body 20 by rotating a rotary shaft 500 positioned in a substantially horizontal state, an annular fixing member 18 for inserting the rotary shaft 500 is fixed to and installed in a hole part 22 of the frame body 20 instead of a type of sliding the rotary shaft 500 by being installed in a frame body hole part 22 by installing an annular packing. The mixer comprises an annular rotary member 100 including a sliding surface 207 orthogonal to the rotary shaft between the fixing member 18 and the rotary member, and integrally rotating with the rotary shaft 500 and driving means for rotating the rotary shaft 500.SELECTED DRAWING: Figure 1 |
