PROBLEM TO BE SOLVED: To provide simplified reinforcement of aggregates composing a seat frame without using high rigidity reinforcement. SOLUTION: The car seat is provided with a structure in which an impact load F is added from a certain direction to a load-bearing section M on an aggregate 30 forming a seat frame in an emergency. Both a first position 35 and a second position 35 pinching the load-bearing section M in the longitudinal direction of the aggregate 30 are connected with one end and the other end of a reinforcement 38, respectively, characterized by that the tension of the reinforcement 38 controls the first position 35 and the second position 35 so as to not to be separated from each other due to transformation of the aggregate 30 in the predetermined direction by the impact load F applied to the load-bearing section M. Therefore even if the impact load F applied to the load-bearing section M on the aggregate 30 forming the seat frame to transform the aggregate 30 toward the predetermined direction, the transformation can be controlled.
