Abstract
A ferrule includes a ferrule body which can be inserted into a through hole of a holding member of a polishing jig, and a flange which is supported on an upper surface of the holding member when the ferrule body is inserted into the through hole, wherein the flange has cutouts provided in a front surface thereof, which is opposed to the upper surface of the holding member.
Claims4
A ferrule comprising:
- a ferrule body which is insertable into a through hole of a holding member of a polishing jig;
- and
- a flange which is provided on said ferrule body and which is supported on an upper surface of the holding member when said ferrule body is inserted into the through hole,
- wherein said flange has a plurality of cutouts provided in a front surface thereof, the front surface of said flange being opposed to the upper surface of the holding member,
- wherein regions of the front surface of said flange in which the plurality of cutouts are formed are wider than regions of the front surface of said flange in which no cutouts are formed,
- wherein the plurality of cutouts extend to an outer peripheral surface of the ferrule body in a cross-sectional plane perpendicular to a direction in which the ferrule body is inserted into the through hole, and
- wherein the plurality of cutouts extend to a rear surface of said flange.

A ferrule comprising:
- a box-shaped ferrule body which is insertable into a rectangular through hole of a holding member of a polishing jig;
- and
- a flange which is provided on said ferrule body and which is opposed to an upper surface of the holding member when said ferrule body is inserted into the through hole,
- wherein a front surface of said flange, which is opposed to the upper surface of the holding member, has four protrusions provided thereon which are brought into abutment with the upper surface of the holding member when the ferrule is inserted into the through hole,
- wherein regions of the front surface of said flange on which the plurality of protrusions are formed are narrower than regions of the front surface of said flange on which no protrusions are formed, and
- wherein the four protrusions are located at positions adjacent respectively to four corners of the ferrule body in a cross-sectional plane perpendicular to a direction in which the ferrule body is inserted into the through hole.
