Abstract
A multifinger hand device has a plurality of finger mechanisms extending from a palm unit. The finger mechanisms include a finger mechanism corresponding to a thumb and other finger mechanisms. Joints of the finger mechanism corresponding to the thumb include a joint closest to the palm unit and having a rotational axis about which the joint is rotatable, the rotational axis extending substantially perpendicularly to the rotational axis of a joint, closest to the palm unit, of one of the other finger mechanisms. The joints, closest to the palm unit, of the other finger mechanisms have respective rotational axes about which the joints are rotatable and which are slightly inclined to each other and extend substantially perpendicularly to a main palm plate of the palm unit. The other finger mechanisms have link mechanisms closest to the palm unit which are fixed to the palm unit with their respective rotational axes being inclined to each other.
