  A second embodiment of the present invention will be described with reference to FIG. This embodiment is different from the first embodiment in the shapes of the hole 11 provided in the facing member 5 and the cushioning material 7. In addition, the same code | symbol is attached | subjected about the same or an equivalent location as the said 1st Embodiment, and detailed description is abbreviate | omitted.

  The facing member 5 (first member) is made of, for example, an ABS resin that is a black synthetic resin. Similar to the first embodiment, the turn-back member 5 is provided with a plurality of pedestal portions 10 at the periphery, and the pedestal portion 10 is provided with a hole portion 11 for positioning with the see-through plate 6. The shape of the hole 11 in the present embodiment is a true circle when viewed from the front as shown by a broken line in FIG.

  The buffer material 7 is a thin sheet having flexibility, and is made of a nonwoven fabric or synthetic rubber. As shown by oblique lines in FIG. 4, the cushioning material 7 is attached to the pedestal portion 10 with an adhesive tape so as to cover the hole portion 11 of the pedestal portion 10 provided in the facing member 5. Further, a cross-shaped cut 14 is provided at a location corresponding to the hole 11. By providing the cut 14 in the buffer material 7, four pieces 15 are formed with the cut 14 as a boundary.
