Claims

[Scope of utility model registration request]

In a support device that supports the thin-walled cylindrical object when boring or drilling the inner diameter of the thin-walled cylindrical object using a machine tool with the small diameter side facing down, the inner circumferential surface of the thin-walled cylindrical object is a ring-shaped fastener formed in accordance with the shape of the outer circumferential surface of the thin-walled cylindrical object so as to tightly fit into the outer circumferential surface of the thin-walled cylinder, the outer circumferential surface of which has a threaded portion formed along the circumferential direction; A pedestal having a threaded part that is screwed into and supported by the threaded part on the outer peripheral surface of the fastener, a fixing part that fixes the lower end of the thin-walled cylindrical object, and chips facing the opening at the lower end of the thin-walled cylindrical object. 1. A support device for a thin-walled cylindrical object, comprising: a support base having a discharge hole and supporting the pedestal.
