Abstract: PROBLEM TO BE SOLVED: To open/close fingers at high speed, to improve responsiveness, to reduce noises and further to simplify a structure by providing a crimping part having a supporting member for fingers, electromagnetic actuator for reciprocatively moving an output part, and link mechanism for opening/closing the fingers while being interlocked with the output part SOLUTION: The main part of a motor-driven artificial hand is composed of a crimping part 1 for freely turnably supporting 1st and 2nd fingers 11 and 12 through a supporting member 13, linear actuator 2 as the electromagnetic actuator for linearly moving an output part 21, link mechanism 3 for opening/ closing the respective fingers 11 and 12 of the crimping part 1 while being interlocked with the linear motion of the output part 21, and wrist part 4 connected to the linear actuator 2 Therefore, any decelerating mechanism or transforming mechanism constituted in the conventional motor-driven artificial hand with a miniaturized motor as a driving source is unnecessitated Further, since the output of the linear actuator 2 is directly transmitted to the link mechanism 3, the speed for opening/closing the fingers 11 and 12 is accelerated and responsiveness can be improved
