Beschreibung
Zusammenfassung:	Disclosed herein is a workpiece holding device (10) including: a plurality of first claw portions (21) disposed to be spaced apart from each other in a predetermined plane and capable of linearly moving in a direction parallel to the predetermined plane; a second claw portion (31) and a third claw portion (41) disposed to face each other in a direction orthogonal to the predetermined plane; and a motion conversion mechanism portion that converts a linear motion associated with movement of the first claw portion (21) into a linear motion in the direction orthogonal to the predetermined plane, transmits the linear motion to the second claw portion (31), and causes the second claw portion (31) to linearly move in the direction orthogonal to the predetermined plane. The first claw portion (21), the second claw portion (31), and the third claw portion (41) each have a grasping surface to abut against a workpiece to be held, and the grasping surface of the first claw portion (21) is different in shape from the grasping surfaces of the second claw portion (31) and the third claw portion (41).
