However, the leather material made of genuine leather is constructed by stitching multiple pieces of leather made of genuine leather with threads to match the outer shape of the vehicle interior member. Is used only in some luxury cars. Therefore, in many vehicle interior parts, a surface pattern that resembles the surface pattern of genuine leather is formed on the surface exposed to the passenger compartment of the synthetic resin skin material, and the yarn used to stitch the skin pieces is reproduced. The stitch pattern to be formed is integrally formed. In addition, it is possible to provide a stitch pattern on the surface of the skin material by providing an uneven shape obtained by inverting the stitch pattern in the same manner as the texture pattern on the molding surface of the mold for molding the skin material.

  However, when a stitch pattern is integrally formed on the skin material, the thread portion forming the stitch pattern has the same color as the surface of the skin material, so that the stitch pattern does not look like the real thing. is there. Therefore, in recent years, the surface of the thread portion forming the stitch pattern is subjected to surface treatment by applying paint with a coating device or laser processing with a laser device (see Patent Document 1), so that stitches with colors different from the surface of the skin material are obtained. A pattern is provided.

  FIG. 6 is an explanatory view showing a state in which a surface treatment is performed by applying a paint to the thread portion 82 forming the stitch pattern 80 integrally formed on the surface 70A of the main body portion 72 in the skin material 70. In this painting operation, a concave holding portion 76 (see FIG. 6A) provided on the outer edge portion 74 of the skin material 70 is engaged with a projecting pin 96 provided on the set portion 92, so that the skin material 70 is Under the setting of the set portion 92, the coating head portion 94 applies the yarn portion (design portion) 82 of the stitch pattern 80 provided on the surface 70A of the main body portion 72 which is the outer surface of the vehicle interior member. A predetermined paint is applied (FIG. 6B).
