With such a configuration, as shown in FIG. 7, the engaging portion 27 enters the groove portion 26 and the seat plate 12 and the foot rest plate 13 are sandwiched between the legs 11. In the structure shown in FIG. 7, when the seat plate 12 and the foot rest plate 13 are slid forward while being sandwiched between the legs 11, the engaging portions 27 abut against the side walls of the groove portions 26. Thereby, the sliding of the seat plate 12 and the foot rest plate 13 in the forward direction is restricted. Therefore, the seat plate 12 or the foot rest plate 13 is too far in front of the chair, that is, the seat plate 12 or the foot rest plate 13 is slid forward, and their front ends exceed the perpendicular Z shown in FIG. 3 (b). Never. By regulating the depth adjustment range of the seat plate 12 or the footrest plate 13 in this manner, even if a baby or the like rides, for example, near the front end of the footrest plate 13, the highchair 10 for a baby can be highly stable without falling down. Property can be ensured.
[0028]
On the other hand, when the seat plate 12 and the foot rest plate 13 are slid backward, the seat plate 12 and the foot rest plate 13 easily come off from the legs 11. Thereby, the mounting positions of the seat plate 12 and the foot rest plate 13 can be easily switched.
[0029]
In addition, as shown in FIG. 8, it is desirable to form a groove (slit) 28 on the surface of the engaging portion 27. The groove 28 is a mark indicating a preferred engagement position of the seat plate 12 and the footrest plate 13 with the leg 11. The user can easily confirm the rearward adjustment range based on the mark. That is, as shown in FIG. 8, if the portion of the engaging portion 27 up to the groove 28 is inserted into the groove 26, the seat plate 12 and the foot rest plate 13 are attached to the legs 11 at preferable positions.
[0030]
