A vehicular seat capable of effectively mitigating lateral direction vibrations is provided. In the present vehicular seat (10), a pair of leg portions (32A) of a headrest frame (32) are coupled to a seatback frame (20) to be relatively turnable about a longitudinal direction axis of a seatback (18). Joint portions 32C are provided between the pair of leg portions (32A) and a middle portion (32B) of the headrest frame (32). Thus, the headrest (14) is made turnable to left and right with respect to the seatback (18). Furthermore, the headrest (14) is urged toward a middle position of the range of turning with respect to the seatback (18) by rubber members that are provided between a headrest support (24) and a support bracket (20C). Thus, when lateral direction vibrations are applied to the present vehicular seat (10), the headrest (14) functions as a dynamic damper.
