Abstract
PURPOSE:To reduce the size of a bar-shaped member unit and to increase the lifetime thereof by forming four and more through-holes from the peripheral surface of a columnar body having a central hole toward the central hole to which the bar- shaped member is inserted, while one sphere is loosely disposed therein. CONSTITUTION:A central hole to which a bar-shaped member 2 is inserted is opened at the axial center of a metallic columnar body 1 for a bar-shaped work holding device, four holes perforated from the peripheral surface toward the central hole are equidistantly opened at a plane vertical to the axial center, one metallic sphere 5d-5g are respectively engaged with the four holes, and the openings of the four holes are covered with one elastic columnar body 4 (rubberlike columnar stopper). Since the radius of the bar-shaped member is suitably 1.2-1.5 times the radius r of a circle which contacts with the four metallic spheres in this manner, the device can be reduced in size, and since biased wear can be avoided, its lifetime can be increased.
