the standing part of the cradle is provided with a guide part that engages the circumferential rail to control the sliding movement of the sliding base.

5. The child car seat according to claim 1, wherein

the base part of the cradle is provided with a guide structure having a straight tilt adjustment section having parallel side walls, and a situation inversion section having the shape of a cylindrical recess and connected to one end of the tilt adjustment section, and

the seat body is provided with a sliding foot penetrating the sliding base, and capable of turning in and sliding along the guide structure.

6. The child car seat according to claim 5, wherein

the sliding foot of the seat body has parallel, opposite side surfaces that slide along the parallel side walls of the tilt adjustment section, and circular parts that slide along a cylindrical side surface of the situation inversion section.

7. The child car seat according to claim 5, wherein

the sliding foot of the seat body is provided with a pair of locking pins for vertical movement interlocked with a releasing lever on the seat body, the tilt adjustment section is provided with a plurality of pairs of first locking pins, the pair of locking pins engage selectively in one of the pairs of first locking holes, and the situation inversion section is provided with a pair of second locking holes to receive the pair of locking pins therein.

8. The child car seat according to claim 7, wherein

the distance between each pair of first locking holes of the tilt adjustment section is equal to that of the pair of second locking holes of the situation inversion section.

9. The child car seat according to claim 8, wherein

each pair of first locking holes of the tilt adjustment section and the pair of second locking holes of the situation inversion section are laterally offset with respect to the longitudinal center axis of the cradle in opposite directions, respectively.

10. The child car seat according to claim 3, wherein

the standing part of the cradle is provided with connecting pins that engage the connecting parts of the seat body.

11. The child car seat according to claim 10, wherein

the connecting pins of the standing part of the cradle are capable of sliding and of being released from the connecting parts.

12. The child car seat according to claim 11, wherein

the slidable connecting pins are connected to operating arms engaged in cam grooves formed in a cam plate vertically movably mounted on the standing part of the cradle, the cam plate is interlocked with a first cam projecting from the cradle into the situation inversion section and capable of being pushed down by the sliding foot of the seat body, the first cam is pushed down to move the cam plate to retract and release the connecting pins from the connecting parts of the seat body, respectively.

13. The child car seat according to claim 12, wherein

a second cam projects from the tilt adjustment section of the cradle, the second cam is interlocked with the first cam, and the second cam is pushed down by the sliding foot to make the connecting pins through the first cam engage with the connecting parts as the sliding foot is moved from the situation inversion section to the tilt adjustment section.

14. The child car seat according to claim 12, wherein

an operating rod capable of being moved forward and backward, is connected to the first cam to lock and unlock the first cam, and an operating dial connected to the operating rod is disposed on a front surface of the cradle.

15. The child car seat according to claim 14, wherein
