In FIG. 5B, the support leg 95 that supports the child seat 90 abuts against the protective component 30 of the cover structure 100 at the lower end. That is, when the child seat 90 is attached to the seat 80 (vehicle seat), the lower end portion of the support leg 95 provided on the child seat 90 and the cover component 10 above the functional component (IPU) are viewed from above the vehicle. The protective component 30 is provided at the overlapping position. That is, the lower end portion of the support leg 95 comes into contact with the protective component 30. The load of the support leg 95 input to the protective component 30 can be supported by the skeleton component 20.

  According to this structure, it is possible to prevent the support leg 95 and the functional part (IPU) from coming into contact with each other by the protective part 30. In addition, since the cover component 10 and the protective component 30 are separated, the rigidity of the protective component 30 in contact with the support leg 95 in the cover structure 100 may be increased. Up and weight increase can be suppressed. According to the embodiment of the present invention, it is possible to increase the rigidity of the cover structure 100 and suppress an increase in weight.
