A child seat apparatus includes a seat, a reclinable backrest, and at least either a pair of side guards rotatably mounted on the backrest or a pair of armrests mounted on the seat, wherein the lateral spacing between the side guards or the armrests is changeable. An interlocking mechanism links the backrest with the side guards or the armrests so that the space between the side guards or the armrests is changed in association with the inclination of the backrest. Specifically, this space is widened as the backrest is reclined. Such an interlocking mechanism, for example, includes driving pins that are driven with an upper end of a bridging bar for supporting the backrest in a reclined state while a pair of driven slots are provided in the side guards for receiving the driving pins respectively. The driven slots are directed at an angle relative to each other so as to be closer to each other at upper ends thereof. Due to this structure, a dimensional allowance is provided around the shoulders of a child when the backrest is reclined into the form of a bed.
