Claims

[Claims for Utility Model Registration] A stay fixed to the seat back, a headrest body that supports the head of a seated person, a support member that supports the body, and a pivot that supports the support member so that it can tilt relative to the stay. A pin, a disc spring fitted to the pivot pin in contact with a support member, and a presser washer fitted to the pivot pin in contact with the disc spring, the tip of the pivot pin protruding from the washer. By caulking, the disc spring is pressed against the support member via the presser washer, the peripheral edge of the disc spring is pressed against the support member, and the support member is pressed against the stay, creating a frictional force between them. In the headrest for a seat, the pivot pin is rotatably fitted to the stay, and fitted to the supporting member, the disc spring, and the presser washer in a relatively non-rotatable manner. Head rest of the seat.
