Abstract
A child car seat comprises a child car seat body, a back portion, and a seat portion connected to the child car seat body. The back portion is rotatably connected to the child car seat body, and the bottom end of the back portion is pulled toward the seat portion side by a spring member at a normal time. At a time of impact, an impact force larger than a force of the spring member rotates the back portion so that the back portion moves away from the seat portion.
