In a vehicle seat, beads are formed to a SC panel, and the beads extend along the seat front-rear direction adjacent to joint portions at seat width direction insides of the joint portions. When repeated load in the seat up-down direction is input to a seat width direction intermediate portion of the SC panel, for example, the SC panel is displaced by the input load in the seat up-down direction, and tensile load in the seat width direction acts on the beads as a result. The beads extend or contract in the seat width direction due to the tensile load. Load input to the SC panel is thereby absorbed by the extension and contraction of the beads, and load in the seat up-down direction input to the joint portions is reduced. This enables concentration of stress at the joint portions to be suppressed. |
