As shown in FIGS. 1 to 4, a window glass 4 which is a multi-layer glass in which a front glass 1 forming a front side portion and a back glass 2 forming a back side portion are joined by a sealing material 3 is used. Is fitted directly into the window opening 7 of the outer plate 6 of the vehicle 5.

For this fitting, the frame 10 is attached to the back of the opening edge 7a of the window opening 7 by welding or the like, so that the window glass 4 has an opening on the inner periphery for receiving and fixing the window glass 4. An annular groove 11 is formed along the window opening 7.

As shown in the longitudinal sectional view of FIG. 1, the window glass 4 has a similar shape in which the front glass 1 is slightly smaller than the window opening 7,
The back glass 2 overhangs in the vertical direction of the front glass 1 more than the window opening 7 to form the overhanging side portions 4a, 4b. The protruding sides 4a and 4b are the front glass 1
On the other hand, the stepped surfaces 8a and 8b having different widths are formed on the front side. Actually, the upper step surface width is made larger than the lower step surface width.

This is effective as a retainer from the annular groove 11 when the protruding portions 4a and 4b of the window glass 4 which will be described below are fitted into the annular groove 11 and settled by its own weight.

In particular, in the window glass 4, the respective protruding side portions 4a and 4b of the back glass 2 are in the annular groove 11 as shown in FIG. 1, and the front glass 1 is substantially at the center of the window opening 7 and the outer plate 6 is formed.
When positioned so as to be flush with the opening edge 7
The play a between the upper side portion of a and the upper side portion of the front glass 1 facing this is the same as the protruding side portion 4 of the back glass 2 on the same upper side.
It is set so as to be smaller than the overhanging dimension c of a from the front glass 1 and larger than the catching margin b between the lower overhanging side portion 4b of the back glass 2 and the lower side of the opening edge 7a opposed thereto. .

Due to the geometrical characteristics having such a dimensional relationship, while the window glass 4 is being lifted as shown in FIG. 4, the upper projecting side portion 4a having the upper step surface 8a of the window glass 4 is connected to the window opening 7. When it is dipped into the back side of the upper side of the opening edge 7a and fitted into the upper side 11a of the annular groove 11 at the back of the opening edge 7a, the lower protruding side 4b having the step surface 8b of the window glass 4 opens the window opening. The lower edge of the opening edge 7a of 7 can be freely moved back and forth.

Therefore, in this state, the lower protruding side portion 4b is moved to the inner side as shown by the phantom line in FIG.
It can be positioned on the lower side portion 11b, and when the window glass 4 is lowered to the predetermined height position of FIG. 1 according to its own weight at this virtual line position, the lower side portion 4b of the window glass 4 is formed into an annular shape. While entering the lower side portion 11b of the groove 11 and having a predetermined catching margin b with the lower side portion of the opening edge 7a, the upper protruding side portion 4a descends but is located in the upper side portion 11a of the annular groove 11, and each portion is Since the window glass 4 is still caught in the annular groove 11 so as to be caught in the annular groove 11, the window glass 4 can be prevented from coming off the annular groove 11, and the window glass 4 cannot be removed unless it is lifted to the imaginary line position. Become.

In order to fit the window glass 4 as described above, however, the overhanging dimension c of the overhanging side 4a of the window glass 4 shown in FIG. 1 is equal to or smaller than the depth e of the annular groove 11. It is a condition.

As a result, the front glass 1 and the outer plate 6 can be positioned so that the front glass 1 and the outer plate 6 are flush with each other.

Then, at the bottom of the lower side portion 11b of the annular groove 11, as shown in FIG.
Is provided to receive the lower side portion 4b of the window glass 4 from below, the window glass 4 can be positioned so that the front glass 1 is located at a substantially central position of the window opening 7 in the vertical direction. By adjusting the left-right position of the window glass 4 above, the front glass 1 can be positioned at the substantially center position of the front glass 1 in the left-right direction of the window opening 7. Therefore, the front glass 1 of the window glass 4
Are positioned substantially in the center of the window opening 7 so as to be flush with the outer plate 6.

In this state, the step surfaces 8a, 8a of the window glass 4 are
b and the opening edge 7a of the window opening 7 at a suitable number of places, in the present embodiment, at two places on the left and right, the same packing material 1 as described above.
By sandwiching 7 further, the window glass 4 can be positioned and strongly held at the predetermined position, and can be stabilized.

A sealing material 18 is filled between the window glass 4 and the window opening 7 and the annular groove 11 so as to be singulated, so that the window glass 4 is sealed between the window opening 7 and the annular groove 11. Can be firmly fixed.

In the structure for mounting the window glass 4 as described above, the necessary members and the number of man-hours required are much smaller than those in the conventional case, and since the operation can be easily performed from the outside of the vehicle, the cost can be reduced and the repair can be performed. It is also convenient.

Moreover, since the window glass 4 is flush with the outer plate 6 of the vehicle 5 together with the sealing material 18 filling the window opening 7, the appearance is simple and the aerodynamic resistance of the window in a high-speed vehicle is reduced. It is possible to avoid the generation of aerodynamic noise.

In this embodiment, the window glass 4 is a multi-layer glass in which the front glass 1 and the back glass 2 are combined, but any multi-layer structure may be used, and one window glass is carved out. Even if it has the front side portion and the back side portion having the step surfaces 8a and 8b, the same operational effect can be obtained.

Further, the protruding side portions 4a, 4 of the window glass 4 are
b may be formed in the left-right direction of the window glass 4. In this case, when the window glass 4 is fitted into the annular groove 11, the movement in the plane direction is the vertical direction in the above embodiment, whereas
