Abstract

PURPOSE: In a vane assembled with metal sheet or synthetic resin, to eliminate the force which shifts the main board and side board in circumferential direction, by reversing the bending direction of approximately half of vane projections.
CONSTITUTION: In a vane comprising main board 1, side board 2 and vane 4 where the projection provided on both sides of vane 4 are inserted into rectangular grooves made in main board 1 and side board 2 then they are bent to assemble a vane, even nember, for example four, of projections 3aW3d, 3eW3h are provided on both sides of said vane 4. When inserting said projections into corresponding grooves in main board 1 and side board 2 then bending, the bending direction of adjascent pairs such as 3a, 3b and 3c, 3d is reversed while the bending works in right and left direction are performed simultaneously to canceel the circumferential forces.
