Abstract
A vehicle seat () is provided with a cushion frame () that can be moved up and down by means of a link mechanism (). To assist the upward movement of the cushion frame (), a torsion bar () is disposed in a connection pipe () having both ends secured to a pair of left and right rear links (). A position holding member () holds the torsion bar () and is supported by the connection pipe (), whereby the positional shift of the axis of the torsion bar () is suppressed. The position holding member () engages an extension portion () extending perpendicular to the shaft portion (), and thus, does not rotate around the axis relative to the torsion bar (). Therefore, in the position holding member (), portions requiring reinforcement against a transverse force from the torsion bar () are limited a narrow range, and the position holding member () can be reduced in size and weight.
