Abstract

In the child seat of the present invention, one side of a cam plate is entirely abutted against an abutting plate. When the cam plate is rotated clockwise by 45°, the cam plate moves toward the front side as guided by a guide disk with a guide frame with rotation of the cam plate, while a corner of four corners of the cam plate constantly abutting against the abutting plate. With this structure, the child seat can be provided which has enhanced securing stability relative to a vehicle seat and which can facilitate in-vehicle handling.
