This makes it possible to stir without damaging the container in which the stirring blade does not come into contact with the inner surface of the container and without mixing the container composition into the object to be stirred.

As shown in FIG. 2 or FIG. 3, the envelope body 5 of this embodiment is composed of a plurality of linear bodies arranged along the extending direction of the rotary shaft 2, and specifically, Is 90 around the axis of rotation 2. It is composed of four linear bodies 5a, 5b, 5c and 5d which are spaced apart. [0025] One end of each of the linear bodies 5a, 5b, 5c, 5d is attached to the tip of the rotary shaft 2, and the other end is attached to the rear side of the portion where the stirring blade 4 is provided. Then, by attaching the one end and the other end forces of the linear bodies 5a, 5b, 5c, and 5d at such positions, it is possible to configure an enclosure that can surround the stirring blade with a simple structure. However, the enclosure in the stirring rod of the present invention is not limited to the structure of this embodiment, and any structure can be used as long as the stirring blade can be enclosed so that it does not protrude. Consisting of a spirally arranged linear body, an annular body force centered on the rotation axis, a belt-like body force with a certain amount of width that is not in the linear body, or a center of rotation axis Such a cylindrical body having a large number of holes through which paint can flow in and out is also widely included in the scope of the present invention.

In addition, the stirring blade 4 has one end attached to the rotary shaft 2 and the other end attached to the enclosure 5. More specifically, one end side is fixed to the rotary shaft 2 by welding, and the other end side is fixed to the enclosure 5 by welding. Thereby, since both ends of the stirring blade 4 are held, the mounting strength of the stirring blade 4 is increased, and separation from the stirring rod 1 can be further prevented.

In addition, it is possible to sufficiently stir the object to be stirred (for example, paint) solidified near the inside of the corner.

[0030] The form in which the tip of the stirring unit becomes thinner than the rear part of the stirring unit is not limited to this embodiment. For example, the tip of the stirring unit is separate from the enclosure. The tip part of the stirring part formed of a member may have a certain thinness that does not gradually narrow toward the tip side. Furthermore, the front part of the stirring part may be formed of a cylindrical body, a columnar body, a polygonal pyramid or the like that is formed thinner than the rear part of the stirring part.

In addition, an annular body 8 (ring) having a substantially circular cross section extends in a direction substantially perpendicular to the rotation shaft 2 at the boundary between the front portion 6 of the stirring portion 3 and the rear portion 7 of the stirring portion 3. As shown, the outer surfaces of the linear bodies 5a, 5b, 5c and 5d are fixed by welding. As a result, the attachment force of the linear body constituting the enclosure is strengthened, and a line is formed at the boundary between the front part 6 of the stirring part 3 and the rear part 7 of the stirring part 3 where a step is generated due to the thickness of the outer shape. It is possible to reinforce the surrounding body which also has a body strength.
