<p>PROBLEM TO BE SOLVED: To sufficiently hold a held member in an easy using method in a clamp nipping and holding the held member.SOLUTION: A clamp 1 comprises: a body member 10 having a location part 11 for locating a rail 100, and an opposite part 13 on which a screw hole 12 is formed at a position opposite to the location part 11; a displacement member 20 that has a rod-like screw part 21 with a screw groove screwed with the screw hole 12, and whose distance from the location part 11 varies together with rotation of the screw part 21; and a lever member 30 for changing torque applied to the screw part 21 against force applied by a user by operation of the user. By such the clamp 1, the user operates the lever member 30, and therefore, the torque when fastening the screw part 21 can be changed, so as to sufficiently hold the rail 100 in an easy using method.</p> |
