<p>A clamping device (C) comprises a clamp main body (1), a gripping assembly (2), a clamp rod (3), a scraper (26), and a drive means (5), the gripping assembly (2) comprises one or a plurality of grip forming members (21) on the outer peripheral side of the clamp rod (3), the clamp rod (3) comprises an intermediate rod section (33) at an intermediate portion thereof, and a tapered section (34) that extends upward from the intermediate portion (33) and that is formed so that its external diameter increases progressively upwards towards its upper end portion and so that it is capable of driving the one or a plurality of grip forming members in the direction to increase the external diameter thereof, the tapered section (34) has one or a plurality of tapered flat surfaces (35) that are abutted in a surface contacting manner with one or more grip claw sections (22) of the one or more grip forming members (21), and one or more partial conical surfaces (36) that are formed between the lower edges of the one or a plurality of tapered flat surfaces (35) and whose radii become progressively larger upwards, and, in the vicinity of the scraper (26), a cross section orthogonal to the axis of the clamp rod of the one or a plurality of grip forming members and the clamp rod is formed into a circular shape.</p> |
