To stabilize a joint state of interior panel components so that a first interior panel component does not become shaky on a surface perpendicular to a joint direction.
At a joint initial stage of a scuff plate 1 and a quarter trim 3, a reference pin 15 on a scuff plate 1 end rear surface is inserted in a reference hole 25 at a quarter trim 3 end. At a joint completion stage of the scuff plate 1 and the quarter trim 3, first and second locking claws 9, 13 on the scuff plate 1 end rear surface are interlocked with first and second locked parts 29, 33 at the quarter trim 3 end. At a joint middle stage of the scuff plate 1 and the quarter trim 3, a locking angle of both of the locking claws 9, 13 with respect to the locked parts 29, 33 is adjusted by sliding the first locking claw 9 on a first guide surface 37 of the quarter trim 3, as well as the first locking claw 9 is abutted on a second guide surface 39 at the quarter trim 3 end. Accordingly, a rotating angle around the reference pin 15 with respect to the quarter trim 3 of the scuff plate 1 is adjusted.
