Claims

[Scope of Claim for Utility Model Registration] (1) Waterproofing of the shaft seal of a stirring member connecting shaft that penetrates the wall of a mixing tank of an agitating mixing device and projects into the mixing tank, and connects the stirring member in a detachable manner at the protruding portion. In the mechanism, the protrusion of the stirring member connecting shaft into the mixing tank is covered with a waterproof cover, and rotation of the stirring member connecting shaft is prevented by a locking member attached to the waterproof cover. An agitation member connection in an agitation mixing device, characterized in that the opening of the waterproof cover is brought into close contact with the wall surface of a mixing tank around the agitation member connection shaft by tightening the cover in the axial direction at the tip of the agitation member connection shaft. Waterproof mechanism for the shaft seal. (2) The stirring member according to claim 1, wherein the locking member is engaged with a key groove formed in a stirring member connecting shaft to connect the stirring member so that the stirring member cannot rotate relative to each other. Waterproof mechanism for the shaft seal of the connecting shaft.
