PROBLEM TO BE SOLVED: To provide a propeller, an agitating machine, and a conveyor for efficiently delivering, agitating, and mixing fine particles and fluids to solve adverse effects caused by hard materials and lumps contained in the article to be handled. SOLUTION: In this propeller 1, a plurality of blades 3, 3 and 3 are spirally spaced from one another in line on the outer periphery of a rotary shaft 2, and a front end 4 in the spiral direction (arrow F) of each of blades 3b is crossed (at a crossing width T) with a rear end 5 in the spiral direction of the adjacent blade 3a going forward in the spiral direction relative to the direction of an axial core C of the rotary shaft 2. The propeller 1 is used for a conveyor V together with a cylinder 8 rotatably accommodated in the propeller 1, and a motor 13 connected with the propeller 1 and rotating the propeller 1 around the axial core C of the rotary shaft 2.
