Abstract
A sleeve-component extracting jig according to the present invention is configured to include an engagement part on which a thread engageable with an inner circumferential surface of a sleeve component is formed, wherein a taper surface configured by cutting off crests of the thread to lower a height of the thread toward a leading end of the engagement part, and a plurality of clearance grooves open at the leading end of the engagement part and arranged at equal angular intervals in a circumferential direction of the engagement part are formed in the engagement part, a length of a radius of the engagement part at an end position of the taper surface is a sum of a length obtained by multiplying a thickness of the sleeve component by a digging ratio (20%˜60%) and a length of an inside radius of the inner circumferential surface of the sleeve component.
