It is open. Further, as shown in FIG. 9, each of the locking recessed grooves 50, 50 has a substantially T-shaped cross section. For this reason, the width dimension Wa of the lower end opening of each of the locking recessed grooves 50, 50 is smaller than the width dimension Wb of the inner portion located above the lower end opening (Wa<Wb). Further, while the width dimension Wa of the lower end opening is sufficiently smaller than the width dimension D of each of the heating foam materials 49, 49 (Wa<D), the width dimension Wb of the inner portion is the width of each heating foam. It is equal to or slightly larger than the width dimension D of the foam materials 49, 49 (Wb≧D). In the case of this example, the heating foams 49, 49 are locked in the locking recesses 50, 50 by sliding them indoors and outdoors to prevent falling downward. is doing. Further, the upper surface of each of the heat-foamable materials 49, 49 is bonded and fixed to the bottom surface of each of the locking recessed grooves 50, 50 with an adhesive. In this way, with the heating foam materials 49, 49 supported and fixed to the lower surface of the support plate portion 42, the plate thickness directions of the heating foam materials 49, 49 coincide with each other in the vertical direction. Further, the respective heat-foamable materials 49, 49 are exposed from a portion between the air-tight pieces 46a, 46b arranged adjacent to each other.

  The fixing pieces 39, 39 used for fixing the windshield main body 38 having the above-described structure to the lower surface of the upper frame 4a are made of synthetic resin such as polyamide resin, and are shown in FIG. As shown, on the lower surface of the upper frame 4a, it is locked in a fixing groove 51 formed in a portion between the pair of upper guide rails 27a and 27b.
