And resin molding 80 continuous along both sides 74, 74
And fitted into an opening 75 formed in the body panel 70A.

The molding 80 may be called a frame, a gasket, a molding, or the like, but is simply called a “mall” in this specification. The upper side 73 of the glass plate 72 refers to a side along the roof 76 of the vehicle 70, and the side of the glass plate 72 refers to a side along the front pillar 77 of the vehicle 70.

[0004] As shown in FIG. 8, a molding 80 is a glass plate.
The upper side mounting portion 81 and the side side mounting portion 82 having a substantially U-shaped cross section continuously engaging with the upper side 73 and the side side 72, and the upper side mounting portion 81 and the side side mounting portion 82 to the glass plate 72. A lip portion 83 and a cover portion 84 extending in the direction away from each other are provided. The framed transparent plate 71 is provided with a backup material 85 interposed between the back surface 72A of the glass plate 72 and the stepped surface 76 of the opening 75, and is appropriately coated along the backup material 85. It is fitted and fixed in the opening 75 by a suitable adhesive 86. At this time, between the upper side 73 and both sides 74 of the glass plate 72 and the opening 75, the above-mentioned lip 83 is elastically deformed and adheres to the opening 75, and is covered by the cover 84, Good waterproofness is obtained.

The transparent plate-like body 71 with a frame is provided with a rain gutter to the molding 80 to collect and drain the rainwater wiped off from the surface 72B of the glass plate 72 by a wiper that repeatedly operates in rainy weather, for example. 90 are provided. Specifically, a side-side rising portion 87 that rises from the side-side mounting portion 82 of the molding 80 along the thickness direction of the glass plate 72 is provided, and is continuous substantially parallel to the surface direction of the glass plate 72. A flange 88 is protrudingly provided on the inner side surface of the side edge rising portion 87,
A rain garter 90 having a substantially V-shaped cross section is provided between the side mounting portion 82 and the flange 88. This Rain Gata 90
The cross-sectional shape is formed so as to gradually and continuously expand from the vicinity of the corner between the upper side mounting portion 81 and the side side mounting portion 82.

[0006] Such a molding 80 is, for example, injection molding in which the upper side mounting portion 81 and the side side mounting portion 82 are integrally molded by a predetermined die, or a slide core which can be protruded and retracted into a molding space. It can be manufactured by extrusion molding or the like in which the upper side mounting portion 81 and the side side mounting portion 82 are continuously formed by an extrusion die having the following. Also, the transparent plate-shaped body 71 with a frame,

[0007]

By the way, in the above-mentioned transparent plate-like body 71 with a frame, in order to increase the drainage efficiency of the rain garter 90, the cross-sectional area of the rain garter 90 must be enlarged over the entire area to increase the volume. Can be considered.
In other words, in order to increase the drainage efficiency of the rain garter 90, the width dimension of the rain garter 90 (rise dimension of the side-side rising portion 87) or the depth dimension of the rain garter 90 (projection dimension of the flange 88) is increased. It can be set.

However, depending on the vehicle speed, it may be difficult to increase the amount of rainwater received by the rain garter 90 simply by setting the width of the rain garter 90 large. In other words, as shown in FIG. 9A, depending on the vehicle speed, if the width of the rain garter 90 is simply set to be large, rainwater is received only on the cover 84 side of the rain garter 90, and
In some cases, rainwater is not received on the glass plate 72 side of the rain garter 90, and the rain garter 90 is not compared with the case where the width dimension of the rain garter 90 is not set large (see FIG. 9B).
It is conceivable that it is not possible to increase the amount of rainwater received for the large width dimension of.

Therefore, it is conceivable to set the depth dimension of the rain garter 90 to be large. In this case, the portion of the glass plate 72 covered by the molding 80 increases (FIG. 9B).
The light transmission area of the window is reduced together with the problem of the appearance. Moreover, it is conceivable that the rainwater may pass over the side-side rising portion 87 if the rising size of the side-side rising portion 87 is not too large. Further, in the molding 80, if the rising dimension of the side edge rising portion 87 and the projecting dimension of the flange portion 88 are set to be large, it is easy to bend at a specific location, and there is a problem that a predetermined strength cannot be obtained. The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a transparent plate-like body with a frame that can improve drainage efficiency of a rain gutter without causing a decrease in strength of a molding and a decrease in a light-transmitting area. Is to do.
