FINGER FOR ROBOT HAND

PROBLEM TO BE SOLVED: To ensure that the fingertip of a finger molding can be located on each side of a subject for gripping and grip it even if there is only a small space on each side of the subject for gripping. SOLUTION: A finger molding 1 designed to be freely switched between a gripping position and a non-gripping position has a fingertip 4 made from a cylindrical soft material open at one end and closed at a loose end, the back 4a and the thick 4b of the fingertip 4 are made flat, and the distance by which the back and the thick are separate from each other is set to a small one so that they almost overlap with each other, so that in the non-gripping position the finger tip 4 can be inserted into a small space on each side of a subject for gripping. With the fingertip 4 inserted, the back 4a and the thick 4b are inflated and separated from each other by the supply of fluid into the fingertip 4 from a fluid supply part 3 to press the thick 4b in its gripping position into contact with the subject for gripping to grip it.
