Numeral 4 is bent downward to make the height of the cushion 103 constant, and a fixed belt 105 built in the inside of the cushion 103 is engaged with a buckle 106 attached to the seat cushion 100 to fix the cushion 103. Then, a protection belt 107 built in the inside of the cushion 103 is attached to the infant for protection. Also,
When an adult rides, the cushion 103 can be raised and used as a normal seat back 101.
