Vehicle seat
A vehicle seat comprising a fastened member and a fastening member. The fastened member comprising a fastened member-side base section formed from metal, and a fastened member-side reinforcement section formed from fiber reinforced plastic (FRP), laminated in a sheet thickness direction over the whole of the fastened member-side base section so as to reinforce the fastened member-side base section. The fastening member comprising a fastening member-side base section formed from metal, and a fastening member-side reinforcement section formed from FRP, laminated in a sheet thickness direction over the whole of the fastening member-side base section so as to reinforce the fastening member-side base section. The fastening member is fastened to the fastened member by bringing the fastening member-side base section into contact with the fastened member-side base section.
1. A vehicle seat comprising:
