By the way, the step of winding the terminal portion of the skin material depends on mechanical work by a dedicated winding machine or manual work by an operator. Challenges or shortcomings were inherent. For example, in the former case of mechanical work using a dedicated winding machine, even if there is an advantage that the work efficiency can be improved by automation and labor can be reduced due to labor saving, the machine is required because a dedicated machine and auxiliary equipment are required. In addition to the increase in equipment costs, there are drawbacks in which it is not possible to cope with complicated shapes. Further, in the case of manual operation by the latter worker, since many steps such as a step of applying an adhesive to the terminal portion, a step of winding the terminal portion, and a drying step are required, workability is low. It has been pointed out that the production cost is increased and the quality is varied. In addition, there is a problem common to both of the following:-"wrinkles" are formed due to loosening of the terminal portion and can not be wound into a predetermined shape;-Partially ruptured by excessive winding of the skin material- It has been pointed out that the adhesion to the terminal portion is insufficient and the film is peeled off after winding.

(See FIG. 11A). Further, each edge 15a of the base body 11,
Since the vicinity of 15b, 15c, and 15d is curved in a curved shape, the holding member 45 is also formed so as to be in close contact with the holding member 45.

[0022]

In the lid member 10 constructed as described above, first, as in the case of the first embodiment, first, a skin is formed by using a crimping mold 35 or a vacuum forming mold 36. A molding and bonding process of the material 25 is performed. That is,
The holding member 45 is integrally formed to form the surface 12 and the outer surface 4.
The substrate 11 having the adhesive applied thereto is molded into a molding die 35 (36).
After setting on the convex mounting portion 38 of the lower die 37 in

Further, the terminal portion 26 extending from the contour edge portion 15 of the base 11 is bonded to the outer surface 47 of each holding member 45.
(See FIG. 4).

When the molding / adhering process of the skin material 25 is completed using the press-molding mold 35 or the vacuum-forming mold 36, the base 11 is removed from the molding mold 35 (36), and the terminal portion is removed. Is performed. In the terminal winding method according to the second embodiment, the inner surface 48 of each of the holding members 45 is used.
After the adhesive is applied to the holding member 4, the terminal portion 26 of the skin material 25 is wound around the back side of the contour edge portion 15 of the base 11, and
5 is adhered to the back surface of the base 11 (see FIG. 11B).
At this time, since each holding member 45 is formed of a harder material than the skin material 25, for example, if only the portion of the terminal portion 26 corresponding to the substantially central portion in the longitudinal direction of the holding member 45 is pressed with a fingertip, The entire terminal portion 26 adhered to the holding member 45 is simultaneously wound. That is, the entire terminal portion 26 can be easily and easily rolled up by only partially pressing the substantially central portion of each holding member 45, and no special technique or skill is required. Moreover, similarly to the first embodiment, the contour edge portion 15 of the base body 11 is formed.
Since the holding member 45 extends to most of the position in the above, there is no inconvenience such as the terminal portion 26 becoming loose and "wrinkling" during the winding operation or being partially pulled and split. The holding member 42 and the step portion 16 may be welded by, for example, ultrasonic waves or heat caulking in addition to bonding with an adhesive.

For this reason, on the premise that each holding member 45 bonded to the terminal portion 26 of the skin material 25 is appropriately harder than the skin material 25 and is molded from a resin material of the same series as the base 11, the holding member 45 has characteristics ( (For example, having high flexibility). That is, if the holding member 45 has a certain degree of flexibility, there is an advantage that even if the base 11 is formed into a curved surface, the base 11 can be easily deformed into that shape. Since the base 11 and the holding members 45 are separated from each other, the convex mounting portions 38 of the lower mold 37 in the molding dies 35 and 36 are not specifically illustrated. A holding means for fixing in a predetermined position is provided.

In the base 11, similarly to the first embodiment, a horizontally long step 16 is formed on the back side of the front edge 15a, the rear edge 15b, the left edge 15c and the right edge 15d. The holding member 45 is aligned with the step 16 when the terminal portion 26 of the skin material 25 is wound (see FIGS. 14 and 15A). In addition, the base body 11 has the respective edge portions 15a, 15b, 15c, 15d.
