Abstract
According to the present invention, there is provided a tool changing device for a robot comprising a piston reciprocating in a cylinder, a supporting block provided at the distal end of a piston rod, a pair of links interconnecting the supporting block to a pair of cramp members cramping a tool mounting plate. Even in a case where the supply of a pressurized fluid is interrupted during the cramped state, and outside uncramping force is applied to the cramp members, a side surface of each cramp member abuts against a side surface of the supporting block, and the cramping members are thereby held in the cramping state.
