PROBLEM TO BE SOLVED: To provide a stirring blade capable of further vigorously stirring an object flowing with the stream of a fluid, with a simple structure by enhancing the stream of the fluid.SOLUTION: A stirring blade (100) includes blade parts (110 and 120) disposed on at least one plane, projecting in the axial direction, and a recess (102) adjacent to the blade parts (110 and 120) in the circumferential direction, and stirs a fluid with rotation. The stirring blade (100) has a plurality of projection parts (111, 121 and 122) arranged at intervals in the radial direction on the front edge side of the rotation direction of the blade parts (110 and 120), with which the fluid collides.SELECTED DRAWING: Figure 2 |
