PROBLEM TO BE SOLVED: To provide a hand device of an industrial robot applying a system driving a plurality of fingers capable of gripping many works including different shapes or sizes by the same hand device, which is inexpensive and capable of realizing large gripping power without requiring one motor in each finger even if it is a small-sized hand device. SOLUTION: When a first servo motor 3 is started, a ball screw 2 is rotated and a block 6 fixed in a ball screw nut 20 is slid. Since a cam follower 5 is stuck in the grooves 71, 72, 72 of the block 6, fingers 4, 16, 16 are oscillated, and opened and closed. When second servo motors 28, 28 are started, second fingers 16, 16 supported by a pair of brackets 15, 15 fixed in a frame 1 turnably around the shaft center coaxial with that of a ball screw 2 are guided by a pair of deep peripheral grooves 72, 72, and turned symmetrically to be opened.
