In the vehicle interior material described in Patent Document 1, when the skin material is attached to a base material having holes by a vacuum forming method, the skin material becomes thin, the grain processing disappears, and shinyness occurs. Since the appearance is impaired due to the damage, the base material and the skin material are punched out at the same time after the skin material is attached to the base material to form holes. However, the vehicle interior material having such a structure is different from the vehicle interior material having a structure in which the skin material is attached to the base material on which the holes are formed and only the skin material is punched out according to the holes. There is a problem with bad sex.

Further, in the vehicle interior material having a structure in which the skin material is attached to the base material on which the holes are formed and only the skin material is punched out according to the holes, punching residue is generated because the skin material is punched out. As a tool for punching out the skin material, a cylindrical tool having a blade at the tip is generally used. If the scraps are left between the members constituting the interior material for vehicles, the scraps may be hindered from assembling, and the scraps must be removed. Then, by using the above-mentioned tubular tool, it is possible to collect the scraps inside the tool. However, there is a problem that it is necessary to remove the debris accumulated in the tool.

Further, in recent years, various parts such as lighting devices and audio equipment may be provided in vehicle interior materials. In particular, since acoustic equipment generates vibrations, it is desirable that the members of the interior materials for vehicles be firmly assembled.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide an assembling structure of an interior material for a vehicle having high work efficiency and high fitting force.
