付けられている。As shown in FIG. 1, the window member 31 that covers the display plate 3 has a substantially half-moon shape in a plan view and has an outer surface that is flush with the outer surface of the panel portion 4, and as shown in FIG. In addition, a first edge portion 32 is provided on the arcuate end portion, and a second edge portion 33 is provided on the linear end portion so as to project downward in the vertical direction. On the other hand, the panel section 4
A circular arc-shaped fitting groove 34 having both ends communicating with the groove portion 21 is formed in the. The window member 31 has a first edge portion 32 fitted in a fitting groove 34 of the panel portion 4, a second edge portion 33 fitted in the groove portion 21, and provided in the second edge portion 33. A projection 36 projecting from the wall surface of the groove 21 is engaged with and attached to the engagement hole 35.
従って、この窓部材31は、第２縁部33の下端を第３図
