A headrest support holds a headrest arranged on a seat by fitting engagement, is supported on a receiving member formed on the seat, and has a through hole for fitting stay of the headrest therein. The headrest support is constituted of an approximately umbrella-like head portion, a neck portion which is formed below the head portion, and an approximately cylindrical barrel portion arranged below the neck portion, wherein the head portion, the neck portion and the barrel portion are formed integrally. A stay-and-receiving-member pressing portion having resiliency is formed by forming a first cut groove in an intermediate portion of the barrel portion and by setting the stay-and-receiving-member pressing portion free in at least two directions from the barrel portion. The stay-and-receiving-member pressing portion is formed in an arcuate shape as viewed in a cross section, wherein a curved inner surface which is curved toward a stay side is formed at a center portion of a curved inner surface, and a projecting outer surface which projects toward the receiving member side is formed on a curved outer surface end portion. And one or plural pairs of resilient members are respectively formed on an upper portion and an intermediate portion of the barrel portion. An outer peripheral portion of the stay is pressed by the curved inner surface and an inner surface of the receiving member is pressed by the projecting outer surface and/or the respective pairs of the resilient members.
