Claims

[Scope of Claim for Utility Model Registration] A spindle that is movable up and down but is associated with a rotation regulating portion to restrict rotation, and has a male threaded portion on its outer circumferential surface, and is set shorter than the spindle, In addition to providing a guide screw hole with a female threaded part that is screwed together with the male threaded part of the support shaft, a pressure chamber is provided to receive operating pressure in order to be able to rotate and to regulate the vertical position. A rotor held by the members, and a workpiece support device comprising the members.
