1. A robot gripping device which has two or more finger parts and has front ends of the finger parts move toward a center of grip so as to grip an object, said device comprising: each said finger part having a finger part body which is comprised of a plate-shaped elastic member, a first anti-slip part which is provided at an inside surface of a front end side of said finger part body, and a reinforcing member which is arranged along an outer surface of said finger part body, is connected to the front end said of said finger part body, and is higher in rigidity than said finger part body, the finger part body of each said finger part is opposed with each other toward the center of grip, said reinforcing member having a first rotary joint which makes said reinforcing member pivot about a first axis of rotation which is vertical to a longitudinal direction of said finger part body and which is parallel with a surface of the finger part body of each said finger part, and said robot gripping device having a drive part which makes a base end of said finger part body move along said center of grip to make said finger part open and close; wherein if the drive part moves a proximal end of the finger part body of each said finger part in the downward direction along the center of grip, the finger part body of each said finger part bends outwardly to separate with each other, so that the finger parts open, and wherein if the drive part moves the proximal end of the finger part body of each said finger part in the upward direction along the center of grip, the finger part body of each said finger part bends inwardly, so that the finger parts close.
