The seat pad has a U-shaped portion formed by a supporting portion, a side surface portion that is continuous with the supporting portion, and a tension adjusting portion that is continuous with the side surface portion, the tension adjusting portion having a protruding portion as a portion of the tension adjusting portion that protrudes toward the seat cover. The protruding portion abuts against the seat cover.

The conveyance seat according to claim 11 , the protruding portion of the tension adjusting portion extends from a body of the tension adjusting portion and defines a generally V-shaped cross-section with respect to the body of the tension adjusting portion, the body comprising a portion of the tension adjusting portion other than the protruding portion.

18. The conveyance seat according to claim 11 , wherein a U shape of the U-shaped portion of the seat pad is independent of the seat pad being part of the conveyance seat.

19. The conveyance seat according to claim 11 , wherein a U shape of the U-shaped portion of the seat pad is maintained independently of application of an external force to the seat pad.
