    摘要: In a seat (10), in a state in which tilting of a back main frame (16) around a tilting center (16A) is locked by a reclining mechanism (18), a lower end of a back joint link (26) is turnably joined to a vehicle side. Thus, turning of a first link (22), a back sub frame (24) and the back joint link (26) is locked, and operation of a back link mechanism (14) is locked. Therefore, a supporting rigidity from rear side of a back side portion (12B) can be enhanced by the back link mechanism (14) (the back sub frame (24)), and a crew sitting in the seat (10) can be thoroughly retained.
