PROBLEM TO BE SOLVED: To provide a broaching jig that can maintain the cylindricity of a machined diameter, which is formed by inner-face broaching of a hollow, cylindrical thin-wall work, at a cylindricity within an allowable range of accuracy equivalent to that in the case of processing thick-wall work. SOLUTION: In the inner-face broaching of the hollow, cylindrical thin-wall work 10, the external circumference face 15 of the thin-wall work 1 is engaged, with a small gap put in between, with the internal circumference face 16 of a hollow, cylindrical auxiliary jig 11, so that the work can be broached by attaching the internal circumference face 17 of the hollow, cylindrical auxiliary jig 11 to the internal circumference face 13 of a work receiver 12, and so that the combined thickness of the thin-wall work 10 and the auxiliary jig 11, when they are engaged with each other, has sufficient rigidity required.
