ABSTRACT:
There is provided a multi-finger hand device which can perform smooth bending and stretching operations of finger mechanisms in holding work of an object or the like while reducing the number of actuators as driving sources of the bending and stretching operations of the finger mechanisms. Wires29aand29b,and wires30aand30bextending from the finger mechanisms2bto2ebiased to the stretching side by springs16or the like are joined to joining element32and33,respectively. A wire31provided extensionally from the finger mechanism2ais wound onto a pulley36and drawn from the base side of the hand3.The joining elements32and33are rockably held by a holding element43via spindles44and45.The holding element43is provided movably and rockably around a spindle42.The pulley36is held by the holding element43and moves together with the holding element43.By pulling the wire31,the bending operations of the finger mechanisms2ato2eare performed collectively. During bending and stretching operations of the finger mechanisms2ato2e,even if any of the finger mechanisms touches an object or the like and is disabled to move, the bending and stretching operations of the other finger mechanisms can be performed.
