Abstract

A seat cushion part includes a base fabric extending between and looped around a front edge frame and a rear edge frame, and having an upper layer part and a lower layer part which are provided apart from each other in an up-down direction. Wire members of metal are provided respectively on side edge portions of the base fabric, and coil springs are spring members each extending between an end portion of the wire member and the front edge frame or the rear edge frame. A load further applied due to vibration, impact, and so on causes the upper layer part to come into contact with the lower layer part to also displace the lower layer part in the up-down direction. Consequently, the coil springs connected through the wire members extend/contract, and their elastic force acts.
