PROBLEM TO BE SOLVED: To solve the problem that a clamp device cannot clamp a workpiece through a grip member to be inserted to a hole of the workpiece on many occasions due to interference between a clamp body of the clamp device and the workpiece. SOLUTION: The clamp device C is provided with a supporting mechanism 40 for supporting the grip member 20 when the grip member 20 is expanded in diameter, a clamping hydraulic cylinder 60 capable of axially advancing and retracting the grip member 20 and a clamp rod 30, and a body member 10 in which the grip member 20, the clamp rod 30, the supporting mechanism 40, and the clamping hydraulic cylinder 60 are mounted. The grip member 20, the clamp rod 30, and the supporting mechanism 40 are mounted near one end of the body member 10, and the axis A of the grip member 20 and the clamp rod 30 is offset from the axis B of the clamping hydraulic cylinder 60 in a direction perpendicular to the clamp rod 20.
