PROBLEM TO BE SOLVED: To restrain shakiness of a child seat caused at sudden brake and collision time by installing a string (a belt) to be fixed to a headrest of a vehicle seat in a back face part of the child seat. SOLUTION: A string (a belt) 4 to be fixed to a headrest 3 of a vehicle seat 2 is installed in a back face part of a child seat 1. Since a lower part of the child seat is fixed by a seat belt and an upper part is fixed by the string (the belt), shakiness of the child seat at sudden brake and collision time can be sharply restrained. Since horizontal shakiness at cornering time can also be restrained, safety and amenity can be enhanced further.
