A seat device has a cushion frame mounted on a floor; a support member for supporting a seat pad; and a torsion bar including a torque bar section and an arm section, for elastically supporting the support member on cushion frame. An arm supporting bracket of substantially cylindrical shape is provided on the support member. A collar rotatably fitted to at least arm supporting bracket has a circumferential flange in a cylindrical shape with a bottom, and is disposed to be facing to an end surface of the arm supporting bracket on the opening side thereof. A tip portion of the arm section is fittedly supported in the opening of the collar. The arm supporting bracket is attached to the support member through a movement absorbing mechanism which allows relative movement with respect to the support member.
