PROBLEM TO BE SOLVED: To simply, speedy and easily form a torsion shaft with a minor process, engaging tightly engagement holes formed in an input axis and an output axis respectably and striking thickness of the input axis against an engagement recess part, or pressing in a pin or screwing a screw so as to be engaged. SOLUTION: This torsion bar 3 combines an input axis 1 and an output axis 2 therebetween. In this case, both end parts 3a and 3b of the torsion bar 3 is formed to be polygon respectably, engagement recess parts 3c are formed at both sides facing each other, respectably thickness of the input axis is striked against the engagement recess part 3c so that a projection part 1a is engaged, and a pin 6 is pressed in or a screw 7 is screwed so as to be combined. |
