According to the first aspect of the present invention, the metal spring is located at a position where the interior panel is attached to the receiving bone member using the mounting screw. The metal spring has an appropriate reaction force that urges the interior panel away from the bone member. Since the amount of deflection of the metal spring changes according to the amount of screwing of the mounting screw, the level of the interior panel continuously changes accordingly. At the time of the change, the interior panel is elastically held at a position corresponding to the screwing amount of the mounting screw by the reaction force of the metal spring without rattling. That is, even if the screwing amount of the mounting screw is increased or decreased, a suitable reaction force is applied to the interior panel from the metal spring, and the interior panel is elastically held at a position corresponding to the screwing amount of the mounting screw. You. In particular, the metal spring has an inclined portion and a horizontal base.
A plate with a bilaterally symmetrical shape in which the tips are sequentially connected
Since the spring is used, the amount of deflection of the metal spring changes greatly.
And the level adjustment range of the interior panel is widened.

Therefore, over a wide range in which the metal spring can bend, in the screwing direction of the mounting screw,
The level of the interior panel can be adjusted steplessly. In this way, since the level of the interior panel can be adjusted, there is no need to attach or cut the level adjustment liner. By simply adjusting the screwing amount of the mounting screw, the level adjustment between the interior panels can be easily performed within a range in which an appropriate reaction force can be received from the metal spring.

Further, although not specifically shown, the mounting screw 4 is coated with a resin for adhering an anti-loosening agent to a thread portion thereof, and is subjected to anti-loosening processing. By the loosening prevention processing, a necessary friction holding force is secured between the mounting portion 3c of the receiving bone member 3 and the screw portion of the mounting small screw 4. Here, as the anti-loosening agent, for example, a special nylon is used, and the thread portion of the mounting small screw 4 is coated by fusion.

After completion of such preparatory work, the passenger compartment interior panel 1 is fastened and fixed to the mounting portion 3c of the receiving bone member 3 by using the leaf spring 5 and the mounting screw 4 in combination. At this time, the position of the passenger compartment interior panel 1 with respect to the mounting portion 3c of the receiving bone member 3 is maintained by the spring reaction force of the leaf spring 5. The amount of deflection of the leaf spring 5 changes in accordance with the amount of tightening by the mounting small screw 4, and applies an appropriate reaction force to the passenger compartment interior panel 1. Therefore, the level adjustment of the cabin interior panel 1 is easily and easily performed by changing the screwing amount of the mounting small screw 4.
