摘要

A clamping device includes a clamp arm attached to a mounting member to be able to reciprocate with respect to the mounting member, a pressure applying mechanism for applying pressure to the clamp arm, and a clamp bolt for clamping a member to be clamped between a support member and the clamp bolt. A threaded cylinder having an external thread portion on the outside and an internal thread portion on the inside is attached to the clamp arm such that the height of the threaded cylinder is adjustable by utilizing the external thread portion. The clamp bolt is screwed to the internal thread portion of the threaded cylinder. A manipulation portion is provided for rotating the clamp bolt in a state where the member to be clamped is clamped between the clamp bolt and the support member.
