A headrest includes linkage supports with high rigidity. The headrest includes a first headrest pillar and a second headrest pillar, a stationary unit disposed between the first and the second headrest pillars, a movable unit which is movable forward away from the stationary unit and backward toward the stationary unit, and a linkage linking the stationary unit with the movable unit. The linkage includes linkage segments. The stationary unit and the movable unit include supports, respectively. The linkage segments are rotatably connected to and supported by the respective supports. The supports each have a width in the widthwise direction and a thickness in the front-rear direction, the width is greater than the thickness. |

1. A headrest comprising:
a first headrest pillar and a second headrest pillar; a stationary unit disposed between the first and the second headrest pillars; a movable unit movable forward away from the stationary unit and backward toward the stationary unit; and a linkage linking the stationary unit with the movable unit, wherein the stationary unit includes a plate-like base fixed to the first and the second headrest pillars and a body attached to a front face of the base, the body being connected to the linkage, the body includes a plate, a plurality of supports rotatably connecting to and supporting respective linkage segments constituting the linkage and a plurality of fixing portions, the plate is fixed to the base with the fixing portions, the supports are integrated with the plate at four corners of the plate so as to protrude forward from the front surface of the plate, and the supports each have a first size in a widthwise direction of the headrest and a second size in an front-rear direction of the headrest, the first size being greater than the second size. |
