<P>PROBLEM TO BE SOLVED: To provide a finger 72 having an excellent structure which can consistently obtain required holding performance by a simple structure at low cost, and secures sufficient durability, and is easily used even in a narrow environment, in a robot hand 7 holding a part P by a plurality of fingers 72. <P>SOLUTION: A coil spring 81 is wound around each of a plurality of fingers 72, and a winding of an intermediate section except both ends is mounted along the outer circumference of each finger 72 in a displaceable manner in the longitudinal direction. Thus, the number of contact points C can be increased when holding a part P so as to be surrounded by the fingers 72, the part P can be consistently held even if the friction force at each contact point is not so large. The size and the pitch of the winding of the coil spring 81 are preferably selected according to the dimension, the shape or the like of the part P. <P>COPYRIGHT: (C)2012,JPO&INPIT |
