Therefore, since the upper lining member 82 can be attached to the inner panel 13 and the inner side reinforcing panel 14 in a state where the rigidity is increased and the shape is stabilized, wrinkles or the like caused by deformation or the like occurring during the attachment can be prevented.

  In addition, since the upper lining member 82 and the holding member 59 are provided with vertical contact portions 123 and 124 that receive a load from above, the rigidity against deformation caused by the load from above can be improved, and The mounting accuracy can be improved by positioning the lining member 82 and the holding member 59 in the vertical direction.

  In addition, since the upper lining member 82 and the holding member 59 are provided with side contact portions 126 and 127 for receiving a load from the side, it is possible to improve the rigidity against deformation caused by the load from the side. The mounting accuracy can be improved by positioning the upper lining member 82 and the holding member 59 in the lateral direction.

  In addition, since the upper lining member 82 and the inner side weather strip 47 are sandwiched between the holding member 59 and the inner panel 13, it is possible to prevent a gap between the inner side weather strip 47 and the upper lining member 82. Accordingly, it is possible to prevent foreign matter from entering and improve the appearance.

  In addition, since the coupling portion 131 that couples the upper lining member 82 is provided on the side of the holding member 59 opposite to the open end 58, the upper lining member 82 and the holding member 59 are reliably integrated by the coupling portion 131. In addition, the upper lining member 82 can be coupled to the holding member 59 without affecting the deployment direction of the airbag 78.

  Furthermore, since the lining main body member 81 is provided so as to sandwich the upper lining member 82 between the holding member 59, the lining main body member 81 can be aligned.

  In addition, since the terminal of the upper lining member 82 is a downward projecting plate portion 106 that turns downward, it is possible to further prevent foreign matter from entering the storage space 66 and improve the appearance of the terminal.

  In addition, since the upper surface lining member 118 disposed above the upper lining member 82 is provided between the holding member 59 and the upper lining member 82 so as to support the upper surface forming portion 118 from below, the vertical contact portions 123 and 124 are provided. It is possible to prevent deformation that occurs when a downward load is applied to the upper surface forming portion 118 of the upper lining member 82 at normal times. In addition, since the upper intermediate plate portion 102 arranged toward the side of the upper lining member 82 is provided with the hinge portion 120, the lid portion 133 of the upper lining member 82 is opened wide when the airbag 78 is deployed. Can be performed smoothly.

  Further, since the side contact portions 126 and 127 for supporting the upper intermediate plate portion 102 from the side are provided between the holding member 59 and the upper lining member 82, the upper intermediate plate portion 102 of the upper lining member 82 is normally provided. It is also possible to prevent deformation that occurs when a load is applied from the side.

  Further, since the lower reinforcing plate portion 125 constituting the side abutting portion 126 is provided on the upper lining member 82 and the hinge portion 120 is disposed in the vicinity of the end portion, the side support portion having relatively high rigidity is provided. 126 and the rigidity difference between the hinge part 120 having low rigidity, the deformation position of the hinge part 120 can be stabilized, and the lower side of the hinge part 120 of the upper lining member 82 can be stabilized by the side contact part 126. The lid portion 133 above the hinge portion 120 of the upper lining member 82 can be favorably rotated around the hinge portion 120 in the state where the upper lining member 82 is supported.

  In the above embodiment, as shown in FIG. 4, the inner side weather strip 47 is provided with a hollow seal portion 135 instead of the abutment tongue piece 54, and the hollow seal portion 135 lowers the lower protruding plate of the upper lining member 82. The gap between the portion 106 and the upper plate portion 34 of the inner panel 13 may be absorbed to close the gap.
