Abstract

Provided is a conveyance seat configured for adjustment of a deflection amount of a seat forming the conveyance seat, i.e., cushion properties of the seat. The conveyance seat includes a seat frame and a buffering body bridged over the seat frame configured to elastically support a seated occupant. The buffering body has a wire having both end portions attached to the seat frame, and a back restriction member configured to support at least a portion of the wire to restrict deflection of the portion of the wire. The wire includes a first right-to-left extending portion and a second right-to-left extending portion that extend in a seat right-to-left direction, and a coupling portion coupling the first right-to-left extending portion and the second right-to-left extending portion. The back restriction member is made of a resin material, and supports the first right-to-left extending portion and the second right-to-left extending portion.
