Vehicle seat

A method for attaching a torsion bar to other parts of a vehicle seat,

• the vehicle seat comprising:
• a base member supported by a vehicle body;
• a frame movable relative to the base member;
• a link mechanism that supports the frame to be movable relative to the base member;
• a drive mechanism that drives the frame;
• and
• the torsion bar that, to urge the frame to a predetermined direction, extends between left and right side portions of the frame and has lateral first and second ends respectively joined to a first portion and a second portion that rotate relative to each other,
• wherein the torsion bar includes a shaft portion extending in a lateral direction,
• the first portion supports the first end of the torsion bar and supports a part of the shaft portion of the torsion bar adjacent to the second end via a position holding member for suppressing displacement of the torsion bar,
• one of the frame and the link mechanism includes a connection member that is rotatable relative to the other,
• the connection member constitutes the first portion,
• the position holding member is received, in part, in the connection member,
• one or more protrusions are provided on an outer circumferential surface of the position holding member, and
• the method comprising the steps of:
• inserting the torsion bar into a through-hole provided on the position holding member;
• rotating the position holding member relative to the shaft portion of the torsion bar about an axis of the torsion bar so as to engage the torsion bar to an engage portion provided on the position holding member;
• and
• inserting the torsion bar to which the position holding member 24 has been mounted into an inner hole of the connection member and making the first end and the second end of the torsion bar engage with the first portion and the other of the frame and the link mechanism, respectively.
