A structure to be grasped of a member including a set of two projecting portions which are formed on and project from a body portion thereof, and are disposed on an imaginary straight line, wherein a pair of grasping portions of a grasping device are moved away from each other along said imaginary straight line to abut respectively against said projecting portions, so that said member is grasped by said grasping device; wherein one of said projecting portions includes a first grasped portion which can be fitted into a grasping recess, formed on one of said grasping portions, so as to be prevented from moving in a direction perpendicular to said imaginary straight line, and a first function portion which is integral with said first grasped portion, and is so formed as to perform a required function; and wherein the other of said projecting portions is different in shape from said one projecting portion but includes a second grasped portion which is substantially similar in shape to said first grasped portion.
