PROBLEM TO BE SOLVED: To contrive an enhancement of outward appearance. SOLUTION: A bead 6 line-contacting with an engaged nail 43 is integrally projected into a bulb set surface 15. By this, it endures against stripping off due to line-contacting with the engaged nail by making arrangement a surface processing part integrated with a reflecting surface 50 thin, uniform and close adhesion in a ridgeline of the bead 6. For example, although the surface processing part is stripped off in the ridgeline of the bead 6, because the stripping of the surface processing part is only caused in the ridgeline of the bead, the stripping is fine, minute and extremely small amount. Accordingly, it is difficult to catch one's sight and it doesn't cause any problem in an outward appearance. |
