PROBLEM TO BE SOLVED: To provide a vehicle seat capable of precluding or effectively suppressing unnecessary deformation and/or displacement such as twisting of a coupling part of a seat cushion with a seat back without resulting in a large size in structural terms. SOLUTION: The arm part 54 of a coupling arm 50 in coupling with the frame 14 of the seat cushion 12 is coupled with the frame 36 of the seat back 34 through a restriction part 56. When the arm part 54 is going to rotate to left or right round the coupling part with a projecting part 52, restricting walls 60 and 62 of the restriction part 56 restrict the rotation of the arm part 54, which precludes or effectively suppresses occurrence of twisting in the projecting part 52. Even without embodying the coupling arm 50 in a larger construction or increasing the rigidity in terms of material, it is possible to suppress or preclude effectively a deflection and/or rattling of the arm part 54, twisting of the projecting part 52, etc. owing to an input of a left-right twisting load centering on the coupling part with the projecting part 52.
