Has characteristics.

  In the present invention, when the base material is pressed toward the vehicle body panel, the displacement restricting portion comes into contact with the vehicle body panel so that the displacement of the base material toward the vehicle body panel can be restricted. Thereby, after a displacement control part contact | abuts to a vehicle body panel, it can suppress that a base material displaces to the panel side.

  And since it has composition which makes a displacement control part contact a body panel via a cover member, the situation where abnormal noise (rattle noise) occurs at the time of contact can be controlled. Such actions and effects are particularly remarkable when, for example, the base material vibrates when the vehicle travels and the displacement restricting portion continuously contacts the vehicle body panel. Furthermore, since the cover member is made of the same member as the skin material, the number of parts can be reduced and the cost for assembly can be reduced as compared with the case where the cover member is made of another member.

  The said structure WHEREIN: The said cover member shall comprise the shape extended from the peripheral edge part of the said skin material, and shall be distribute | arranged in the form which covers the opposing surface side with the said vehicle body panel in the said base material.

  Further, it is an interior material for a vehicle constituting a door trim having a trim board and an ornament, wherein the skin material is a skin material that covers a base material on the trim board side of the base material, and the displacement regulating portion May be formed on the ornament-side base material among the base materials.
