Artificial hand

An artificial hand comprising a plurality of fingers opposite to one another;

• a support part for rotatably supporting the fingers;
• driving devices mounted on a grasp part integrated with said support part;
• and a finger opening-and-closing operation part for converting a rotation output of said driving device to an opening-and-closing operation of said fingers, wherein
• two of said driving devices are arranged in parallel, one of said driving devices being rotatable together with said fingers, the other of said driving devices being rotatably arranged in a wrist part, one of said driving devices and the fingers being rotated together around a position near a root part of the fingers as the rotation center using the other of said driving devices.

An artificial hand comprising a plurality of fingers opposite to one another;

• a support part for rotatably supporting the fingers;
• a driving device mounted on a grasp part integrated with said support part;
• a conversion device for converting a rotating output of said driving device to a linear motion;
• and a finger opening-and-closing operation part for converting the linear motion of said conversion device to an opening-and-closing operation of said fingers, which further comprises:
• a hold part for rotatably holding said support part arranged above or at an upper part of said driving device;
• a terminal device held by a wrist part;
• another driving device arranged in said terminal device, a rotating output of said another driving device being converted to a rotational motion of said support part;
• and
• a rotating mechanism for rotating said fingers and said driving device around said hold part.
