Embodiments of the present invention will be described below with reference to the drawings.

1 and 2, reference numeral 1 denotes a roof, and an opening 1a is formed in the roof 1. The opening 1a
The left and right guide rails 2 are arranged along the lower sides on both sides of the
The left and right sides of a lid 3 made of glass or the like are supported by the left and right guide rails 2 via a driving shoe and an elevating mechanism, and the driving shoes are guided by the guide rails 2 by the driving of a driving mechanism (not shown) and slide in the front-rear direction. It is configured to be.

When the driving shoe slides rearward, the lifting mechanism first operates downward from the fully closed state in FIG. 1A to lower the lid 3 as shown in FIG. 1B.
Thereafter, as shown in FIG. 1C, the lid 3 was slid rearward to the open state, and by sliding the drive shoe forward, the lid 3 was slid forward as shown in FIGS. 1C and 1B. Thereafter, the lifting mechanism operates upward to raise the lid 3 to bring the lid 3 into a fully closed state in which the lid 3 is flush with the roof 1 as shown in FIG. The structure of the mechanism and the opening / closing operation of the lid 3 by sliding of the driving shoe are the same as those conventionally used and publicly known, and therefore detailed illustration and description are omitted.

Reference numeral 4 denotes a drain plate for receiving rainwater leaking from the rear edge of the lid 3 and discharging the drain water to the outside. A drain shoe 5 is connected to both sides of the drain plate 4, and the drain shoe 5 is connected to a guide rail. 2, slidably fitted to the lid 3, and the lid 3 is connected to a member on the lid 3 side, for example, a lower surface portion on both sides of the lid, and the lid bracket 3 a is connected by a connecting member 6.
The drain plate 4 is guided by the guide rail 2 and slides in the front-rear direction in accordance with the slide movement in the front-rear direction.

The drain plate 4 has a bottom surface 41 and a front wall surface 42 rising upward from a front edge and a rear edge thereof.
The rear wall 43 has a substantially U-shaped cross section. The front wall 42 has a lower height than the rear wall 43 to secure a space for the rear part of the lid 3 to descend. I have. A vertical wall member 7 made of an extruded product of an elastic material such as rubber, for example, is fitted to the front wall surface 42.

The vertical wall member 7 has a mounting portion 72 having a vertical groove 73 fitted on the front wall surface 42 of the drain plate 4, and an upwardly inclined front portion from the front corner of the upper end of the mounting portion 72. A projection 74 projecting into the groove is formed on a rear inner wall surface of the front and rear inner wall surfaces of the vertical groove 73 provided in the mounting portion 71 in a longitudinal direction (see FIG. 4). It protrudes continuously in the vehicle width direction).

The vertical groove 73 of the mounting portion 72 is inserted into the front wall surface 42 of the drain plate 4 so that the vertical groove 7 is formed.
While the third protrusion 74 elastically contacts the inner surface of the front wall surface 42,
The front inner surface of the vertical groove 73 is attached to the outer surface of the front wall surface 42 by pressing.

In the state where the vertical wall member 7 is attached to the front wall surface 42 of the drain plate 4 as described above, as shown in FIG. By extending the vertical surface portion 71,
The substantial height of the front wall surface 42 is substantially the same as the height of the rear wall surface 43, and it is possible to prevent water leaking from the rear edge of the lid 3 from entering the room.

When the lid 3 is lowered, the rear portion of the lid hits the vertical surface portion 71 of the vertical wall member 7. However, as shown in FIG. 1B, the lip-shaped vertical surface portion 71 is elastically deformed.
When the lid 3 is raised and separated from the vertical surface 71 without any hindrance to the lowering operation of the lid, the vertical surface 71 is elastically restored and returns to the original state.

When the vertical surface portion 71 is elastically deformed by the raising and lowering operation of the lid 3 as described above, the reaction force is applied to the fitting portion of the mounting portion 72 to the front wall surface 42. Since the wall surface and the inner surface of the front wall surface 42 are in contact with the projection 74, they are much more easily elastically compressed and deformed than in the case of the entire inner wall surface, and the spring action due to the elastically compressed deformation is large. The pressure contact between the inner wall surface on the front side of the vertical groove 73 and the outer surface of the front wall surface 42 is further increased, the mounting strength of the mounting portion 72 as a whole is sufficiently increased, and the reaction force of the elastic deformation of the vertical surface portion 71 is ensured. Supported by

The rear inner wall surface of the vertical groove 73 and the front wall surface 42
The inner surface is contacted by the projection 74, so that the water can be prevented from flowing around due to surface tension.

FIGS. 2A and 2B show another embodiment of the vertical wall member 7, respectively. FIG. 2A shows the longitudinal direction (vehicle width) on both inner wall surfaces before and after the vertical groove 73. FIG. (B) projectingly, and the inner and outer surfaces of the front wall surface 42 of the drain plate 4 can be fitted and attached in a state of elastic contact with the projections 74, 74. FIG. As in the case of the first embodiment, the protrusion 74 is provided only on the inner wall surface on the rear side of the vertical groove 73, and the lower end of the front wall portion of the mounting portion 72 is bent backward to form the hooking portion 75. In a state where the vertical groove 73 is fitted and attached to the front wall surface 42 of the drain plate 4, the hooking portion 75 wraps around and engages with the bottom surface 41 from the corner at the lower end of the front wall surface 42 of the drain plate 4, thereby making it more difficult to remove. An example is shown. 2A and 2B, the configuration other than the above is the same as that of FIG. 1, and the same reference numerals as those in FIG. 1 represent the same parts as those in FIG.

The drain structure of the present invention is not limited to the sunroof device shown in the drawing, but can be applied to any conventionally known sunroof device having a lid elevating operation when the lid is opened and closed.

[0024]

As described above, according to the present invention, there is provided a mounting portion having a vertical groove fitted to the front wall surface of the drain plate, and a lip-shaped vertical surface portion extending upward from an upper end of the mounting portion. In a vertical wall member integrally formed of an elastic material in shape, at least on the inner wall surface on the rear side of the inner wall surfaces before and after the vertical groove, a projection projecting into the groove is formed so as to protrude continuously in the longitudinal direction. In a state where the vertical groove is fitted and attached to the front wall surface of the drain plate, at least the inner wall surface on the rear side of the vertical groove and the inner wall surface of the front wall surface of the drain plate are configured to be in elastic contact with the projection. As a result, not only the mounting strength is improved and it is difficult to remove the water, but also water is prevented from flowing around due to surface tension almost completely.

Also, the mounting can be performed by a simple operation of merely inserting the vertical groove into the front wall surface of the drain plate, so that the mounting workability can be improved, and it can be formed by extrusion of an elastic material such as rubber. It is advantageous in terms of cost, physical distribution, and can stabilize quality, and can bring a great effect in practical use.
