<p>PURPOSE: To improve the rigidity of a finger without increasing the thickness and weight thereof. CONSTITUTION: In a finger in which a flat plated finger main body 1 is horizontally cantilevered and a base plate is put on the finger main body 1 so as to be carried, the free end side and the fixed end side of the cross sectional shapes of the finger main body 1 are respectively formed in a first shape A and a second shape B, the cross sectional area of the second shape B is enlarged in comparison with the first shape A, and a ratio that the part L1 of the first shape A and the part L2 of the second shape B are occupied within a distance between a fixed end and a base plate centroid supporting position, is set to 1:1.3-1:3.4.</p> |
