Summary:To provide a vehicle seat in which a metal frame can be shared between seats that adopt springs with different hook diameters.SOLUTION: A vehicle seat has a seat cushion side frame 20, and a seat back side frame 30. In the vehicle seat, the seat cushion side frame comprises: a left side frame 21; a right side frame 22; a connection plate 23 that connects the left side frame and the right side frame in the front; a connection pipe 24 which connects the left side frame and the right side frame in the rear; and a spring 50 that supports a cushioning material of a seat cushion. The spring has a hook 501 at ends on both sides, and has such configuration that the hook at one end of the hooks at the ends on both sides is suspended on the connection pipe. An adapter, which has an inner diameter substantially equal to an outer diameter of the connection pipe and has an outer diameter substantially equal to an inner diameter of the hook at one end of the spring, is detachably attached to the connection pipe.SELECTED DRAWING: Figure 2 【課題】フックの径が異なるバネを採用するシートの間で、金属製のフレームの共通化が可能な車両用シートを提供する。【解決手段】シートクッション側フレーム20と、シートバック側フレーム30を有する車両用シートにおいて、シートクッション側フレームは、左側サイドフレーム21と、右側サイドフレーム22と、左側サイドフレームと右側サイドフレームとを前方で連結する連結プレート23と、左側サイドフレームと右側サイドフレームとを後方で連結する接続パイプ24と、シートクッションのクッション材を支持するバネ50とを備え、このバネは両側の端部にフック501を有してこの両側の端部のフックのうち一方の端部のフックを接続パイプに懸架する構成を有し、接続パイプには、この接続パイプの外径にほぼ等しい内径を有してバネの一方の端部のフックの内径とほぼ同じ外径を有するアダプタを接続パイプに対して着脱可能に装着して構成した。【選択図】図2
