Claim:
1. A suction-type robot hand for gripping a workpiece which has a mutually intersecting first surface, second surface, and third surface, comprising: a main body part; a first static abutting part which projects from the main body part in a projecting direction, and has a first abutting surface against which the first surface of the workpiece physically abuts; a second static abutting part which extends from the main body part in the projecting direction, and against which the second surface of the workpiece physically abuts; a third static abutting part which extends from the main body part in the projecting direction, and against which the third surface of the workpiece physically abuts; and a suction member attached to the main body part, and having a suction surface which physically abuts and holds by suction the first surface of the workpiece, wherein the suction member projects from the main body part in the projecting direction, and wherein the suction member is deformable into an elongated shape in the projecting direction when suction is not applied to the suction member, and into a contracted shape in the projecting direction when suction is applied to the suction member, the contracted shape in the projecting direction physically limited by the first static abutting part.
