<p>A clamp device (C) is provided with a supporting mechanism (40) for supporting a 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).</p> |
