[Object] An object is to provide a child seat of an ISO-FIX system in which it is not necessary to remove a seat surface part where the child sits when the child seat is attached to or removed from a vehicle, in which it is possible to prevent the child seat from being removed from the vehicle resulting from an erroneous operation and in which it is possible to reliably lock a lock portion to an attachment reception portion of the vehicle. [Solving means] An extension and contraction position of the lock arm includes: an extension and contraction control range which is a range of use in a state where the child seat is fitted to the vehicle; and an attachment and removal control range which is in a position where the lock arm extends as compared with the extension and contraction control range. A means which cancels a state where the child seat is fitted is configured such that the means can be performed with a plurality of operation means. Furthermore, the child seat includes a contraction lock mechanism which is operated as the engagement of the lock portion with the attachment reception portion is cancelled, the contraction lock mechanism prevents, when the contraction lock mechanism is operated, the movement of the lock arm to the extension and contraction control range and the contraction lock mechanism is cancelled by the engagement of the lock portion with the attachment reception portion. |
