In the mounting structure of the vehicle interior material disclosed in FIG. 6 of Patent Document 1, the shaft portion of the temporarily held bolt protrudes from the vehicle interior material toward the vehicle body panel. Therefore, when trying to align the vehicle interior material at a predetermined mounting position in the mounting work, the tip of the shaft portion of the bolt may become an obstacle and the bolt may fall off from the vehicle interior material. In particular, when an external force is applied to the vehicle interior material and the tip of the bolt comes into contact with the vehicle body panel and receives an impact, the bolt falls off significantly.

In the mounting structure of the vehicle interior material disclosed in FIGS. 1 and 2 of Patent Document 1, although the temporarily held bolt does not protrude from the vehicle interior material toward the vehicle body panel, the structure of the mounting convex portion that temporarily holds the bolt is In addition to being complicated, the configuration was complicated, such as the need for a temporary support member with a processed leaf spring. In addition, when temporarily holding a bolt, the bolt is housed in the mounting convex part, the tip of the bolt and the flange part are aligned with the insertion hole and the jaw part, respectively, and the bolt is pressed by the temporary support member. It took time and effort. Further, since the temporarily held bolt is only pressed against the mounting convex portion by the temporary support member from the side of the flange portion, it is easy to fall off when an external force is applied to the vehicle interior material.

In order to solve at least one of the above problems, the present invention includes a bolt fixing portion formed integrally with the vehicle interior material, and the vehicle interior material is provided by using a bolt penetrating the bolt fixing portion. In the structure to be mounted on the vehicle body panel, a temporary holding portion that is connected adjacent to the bolt fixing portion and is inclined in a direction away from the vehicle body panel is further provided. A slit is formed that continuously extends from the bolt fixing portion to the temporary holding portion. The bolt is temporarily held with its shaft portion penetrating the slit in the temporary holding portion and a retaining washer fitted in the shaft portion.

According to the above configuration, the temporary holding portion that temporarily holds the bolt adjacent to the bolt fixing portion is inclined in a direction away from the vehicle body panel. Therefore, when the vehicle interior material is aligned with a predetermined mounting position in the work of mounting the vehicle interior material on the vehicle body panel, the tip of the shaft portion of the temporarily held bolt does not hit the vehicle body panel and does not get in the way. Even if an external force is applied to the vehicle interior material, the temporarily held bolts do not hit the vehicle body panel and receive an impact, and the bolts can be prevented from falling off. In order to temporarily hold the bolt, it is only necessary to pass the shaft part through the slit and fit the retaining washer into this shaft part. To attach the vehicle interior material to the vehicle body panel, the retaining bolt is used to temporarily hold the bolt. The workability is good because the bolt can be moved from the temporary holding portion to the bolt fixing portion as it is along the slit and screwed into the screwed portion of the vehicle body panel without removing the bolt.

Preferably, a clip seat formed integrally with the vehicle interior material is further provided, and a clip used for mounting the vehicle interior material on the vehicle body panel is attached to the clip seat.
