PURPOSE: To obtain the structure that the positioning of bodies is comparatively arbitrary when gripping the bodies and bodies can be positioned in high accuracy after gripping the bodies, by arranging an auto-hand by a plurality of links and arms.

CONSTITUTION: When working an operating source 4 in the left direction in the figure, a yoke 3 also follows up, and arms 1, 1' interlocking connected function in a symmetrical shape because the arms are connected to links 2, 2' oscillating with rotary middles p, q and subject to regulation. Thus, the arms 1, 1' hold a body A from both sides. The operating source 4 may be worked in the right direction in the figure in order to release the body A.
