In particular, the present invention relates to a fixed window mounting structure suitable for a vehicle running at a high speed such as a Shinkansen vehicle.

[0002]

2. Description of the Related Art A fixed glass window of a high-speed running vehicle such as a Shinkansen vehicle has a multi-layered glass structure from the viewpoint of soundproofing and heat insulation. From the viewpoint of ease of operation, a method is adopted in which a window unit in which a window glass and a window frame are integrated is attached to a window opening.

FIG. 4 shows a conventional vehicle window mounting structure employing the above-described double-glazing structure and window unit mounting method. In this window mounting structure, the multi-layer window glass 1 is fitted into the glass fitting groove 4 of the window glass mounting peripheral frame 2 and the holding frame 3 via the cushioning material K to form the window unit 5. Is attached to the window mounting opening 7 of the vehicle outer panel 6, and the window glass mounting peripheral frame 2 is formed with the vehicle outer wall of the glass fitting groove 4 at the vehicle outer end of the peripheral frame substrate 2 a. An inward flange portion 2b is provided, and a mounting flange portion 2c protruding outward at an inner end of the vehicle. Then
In the window unit 5, the mounting flange portion 2 c of the window glass mounting frame 2 abuts on the inner end side mounting flange portion 6 b of the opening frame portion 6 a forming the window mounting opening 7 of the vehicle outer panel 6.

However, according to the window mounting structure shown in FIG. 4, a considerably large step D is formed between the outer surface of the multi-layer window glass 1 and the outer surface of the vehicle outer panel 6. Such a step D increases the air resistance during traveling, which is not preferable for a high-speed traveling vehicle such as a bullet train.

In order to solve the above-described problem of the step, as shown in FIG. 5, a window mounting structure shown in FIG. A thick glass is used for the outer glass 9a, and an end of the thick glass 9a is cut off to form a concave step L between the outer glass 9a and the inner glass 9b. It is conceivable to arrange it flush with the outer surface,
Then, the thickness of the outside glass 9 becomes extremely large, which results in an increase in weight, which is not preferable.

In any of the window mounting structures shown in FIGS. 4 and 5, since the window glass mounting peripheral frame 2 is integrally connected to the vehicle outer panel 6, the window frame mounting peripheral frame 2 is connected to the vehicle outer panel 6 during traveling of the vehicle. The generated vibration is directly transmitted to the window frame mounting frame 2, causing the window unit 5 to rattle and generate noise, and the vibration causes damage to the glass.

[0007] In view of the above-mentioned problems of the conventional window mounting structure, the present invention eliminates the step between the outer surface of the multi-layer window glass and the outer surface of the vehicle outer plate without increasing the thickness of the glass as in the prior art. To provide a vehicle window mounting structure in which the weight of the vehicle is reduced as much as possible and the vibration of the vehicle outer panel is not transmitted directly to the window unit by elastically supporting the window unit with respect to the vehicle outer panel. It is.
