The connecting rod member mounting jig shown in FIGS. 1A and 1B is applied to a connecting rod as shown in FIG. 5 with an outer diameter of the member (BO) of φ25 mm (d1) (BO1), φ28 mm (d2) (BO2), φ32 mm (d3) (BO3), φ38 mm (d4) (BO4), φ42 mm (d5) (BO5) It is called type 2 type applicable to various types, and in addition to this, type 3 other than the above is not shown, but the outer diameter is φ18 mm (d1 ′) (BO1 ′), φ22 mm (d2 ′) (BO2 '), φ25mm (d3') (BO3 '), φ28mm (d4') (BO4 '), φ32mm (d5') (BO5 ') A small size and length are also provided separately. Further, if necessary, it is possible to manufacture a connecting rod member mounting jig applicable to connecting rod members having dimensions and shapes other than those described above. In this case, it is also necessary to consider the rotational performance (rotational force) of the impact wrench (IR) to be used.

The size of the rotation transmitting portion (1) on the tip side of the connecting rod member mounting jig is a large cylindrical shape made of iron having an outer diameter of about 76 mm, a length of about 85 mm, and a wall thickness of about 3 mm to 5 mm. A conical hole having a large inner diameter (D1) and a small inner diameter (D2) of 50 mm, 20 mm × depth (H) 75 mm is formed in the inner center of the cylindrical box. (1b ′) is formed, and the rear end side is fitted with a falling prevention pin (2b) having an outer diameter φ of about 5 mm and a length of about 22 mm in a direction perpendicular to the shaft core.
