Document Type and Number:
WIPO Patent Application WO/2011/086835
Kind Code:
A1
Abstract:
Disclosed is a two-shaft clamp device with improved positioning accuracy in clamping operations and improved operability, which initially clamps a first shaft by tightening a screw and then clamps a second shaft by further tightening the same screw. The two-shaft clamp device comprises a case (10), a clamp body (20) supported by the case, and a fastening bolt (33) screwed into the case. By tightening the fastening bolt (33), the end of the bolt presses the clamp body (20) and, first, the first shaft (31) is held from both sides by a first shaft contact surface disposed on the case side, and a first shaft contact surface disposed on the clamp body; next, a second shaft (32), which passes through a second shaft insertion hole in the clamp body, is supported by means of a configuration easily elastically deformable by means of a slit (23) provided on the side of the aforementioned second shaft insertion hole.
