Abstract

See full text

A gripping device includes a spring member provided between a gripping member body and a shaft so that driving of a gripping driving cylinder causes a driving force to be transmitted from the gripping driving cylinder to the body while the shaft and the body are held in a predetermined positional relationship; so that the body is allowed to retreat with respect to the shaft by elastically deforming the spring member by an opposing force received from a processing object that contacts the body as a result of rotating the body; and so that contact pressure of the body with respect to the processing object is increased by an elastic force of the spring member as the body retreats.
