Abstract

Abstract A child seat is formed of a child seat main portion for holding a child having an engaging member, and a base on which the child seat main portion is detachably mounted. The base has a connecting portion to be connected to a vehicle, and a fixing member to be engageable with the engaging member of the child seat main portion. An engagement releasing member is installed in the base or the child seat main portion for releasing an engagement between the fixing member and the engaging member. Since the base can be connected to the vehicle without the child seat main portion, the child seat can be extremely simply fixed to the vehicle.
