  Hereinafter, an embodiment of the roof apparatus will be described. In the following, the front-rear direction of the vehicle is referred to as “front-rear direction”, the inner side in the width direction of the vehicle toward the vehicle interior is referred to as “vehicle inner side”, and the outer side of the vehicle in the width direction toward the vehicle outer side is referred to as “vehicle outer side”. That's it.

  As shown in FIG. 1, a substantially square opening 10a is formed in a roof 10 of a vehicle such as an automobile, and a sunroof device 11 is mounted. The sunroof device 11 includes a deflector 12 that extends in the width direction of the vehicle and is arranged and supported at the front edge of the opening 10a, and moves in the front-rear direction to open and close the opening 10a. A substantially rectangular movable panel 13 is provided.

  The deflector 12 is attached so as to be able to perform a so-called tilt-up operation in which the front part moves upward by rotating around the rear part. When the movable panel 13 is opened, the deflector 12 is released from the movable panel 13 and tilts up, and protrudes upward from the top surface of the roof 10 (deployed state). Alternatively, the deflector 12 is pressed down from the movable panel 13 with the closing operation of the movable panel 13 and fits below the upper surface of the roof 10 (stored state). The deflector 12 is in an unfolded state when the opening 10a is opened, thereby preventing air vibrations due to wind being caught in the vehicle interior.

  The movable panel 13 is attached so that a tilt-up operation in which the rear part rises with the front part as a fulcrum and a slide operation in the front-rear direction. In the opening / closing operation of the opening 10a by the movable panel 13, a so-called outer sliding type is employed in which the sliding operation is performed in the tilt-up state.

Next, the structure of the sunroof device 11 related to the opening / closing operation of the movable panel 13 will be described.
As shown in FIG. 2, a pair of guide rails 14 are disposed at both edges of the opening 10 a in the width direction of the vehicle. Each guide rail 14 is made of, for example, an extruded material of an aluminum alloy, has a constant cross section in the longitudinal direction, and extends in the front-rear direction. The front ends of the guide rails 14 are connected to each other via a front housing 15 that extends in the vehicle width direction.

At both front ends of the guide rails 14 near the vehicle interior, both longitudinal ends of the deflector 12 are supported so as to be rotatable around an axis extending in the width direction of the vehicle.
A pair of functional components 20 are guided and supported on both guide rails 14 so as to be movable in the front-rear direction on the vehicle outer side than the deflector 12. The movable panel 13 is linked to and supported by both functional parts 20 in a state of being bridged between them. The two functional components 20 cause the movable panel 13 to perform a tilt-up operation or a slide operation in accordance with the movement in the front-rear direction along the guide rail 14.

  In addition, an electrical drive source 16 such as an electric motor having an output gear is installed in the longitudinal middle portion of the front housing 15. This electrical drive source 16 is connected to each functional component 20 via each of a pair of substantially belt-like drive belts 17 made of, for example, a resin material, and simultaneously moves both functional components 20 in the front-rear direction.

  As shown in FIGS. 3A and 3B, a support bracket 21 made of, for example, a metal plate is provided at the lower part of each edge of the movable panel 13 in the width direction of the vehicle. The support bracket 21 is connected to the functional component 20 on the vehicle outer side than the deflector 12, and is supported by the guide rail 14 so as to be rotatable and slidable through the functional component 20. That is, the movable panel 13 is supported by the guide rail 14 via the support bracket 21 and the functional component 20, and thus performs the above-described opening / closing operation with the driving force of the electrical driving source 16.

  As shown in FIG. 5, a cover portion 22 that protrudes toward the vehicle inner side and the vehicle outer side of the support bracket 21 is integrally provided on the upper portion of the front end portion of the support bracket 21. Therefore, the cover part 22 moves integrally with the opening / closing operation of the movable panel 13. In the cover portion 22, a first vertical wall 31 and a second vertical wall 32 constituting a vertical wall are juxtaposed in the front-rear direction, and the width of the vehicle is between the first vertical wall 31 and the second vertical wall 32. A drainage groove 33 communicating with the direction is formed. In other words, the first vertical wall 31 and the second vertical wall 32 prevent water flowing through the drainage grooves 33 from flowing forward and rearward of the vehicle, respectively.

  As shown in FIGS. 4A and 4B, the guide rail 14 is formed with a guide groove 41 communicating in the front-rear direction, and the rail-side drain groove 42 adjacent to the vehicle outer side of the guide groove 41. Is formed. The functional component 20 is guided and supported by the guide rail 14 so as to be movable in the front-rear direction in the guide groove 41. The rail-side drain groove 42 is located on the vehicle outer side with respect to the support bracket 21 and communicates with the movable panel 13 in the front-rear direction along the widthwise edge of the vehicle. The rail-side drain groove 42 allows water that has dropped from the edge of the movable panel 13 in the width direction of the vehicle to flow in the front-rear direction.

  On the other hand, the front housing 15 is formed with a first housing-side drain groove 46 that communicates in the vehicle width direction along the front edge of the movable panel 13, and on the vehicle exterior side of the first housing-side drain groove 46. A second housing side drain groove 47 is formed adjacently. The first housing side drainage groove 46 discharges water that has dropped from the front edge of the movable panel 13 to the outside in the width direction of the vehicle. The second housing side drainage groove 47 is formed in a substantially U-shaped cross section including the guide rail 14 from below, receives the water flowing in the front-rear direction through the rail side drainage groove 42 and discharges it to the outside.

  In the fully closed state of the movable panel 13, the drainage groove 33 of the cover portion 22 has the vehicle inner end and the vehicle outer end positioned directly above the first housing side drainage groove 46 and the second housing side drainage groove 47, respectively. Yes. Accordingly, water such as rain water dropped from the movable panel 13 to the cover portion 22 is guided to the inside of the vehicle by the drainage groove 33 and discharged to the first housing side drainage groove 46, or is guided to the outside of the vehicle and secondly. It is discharged to the housing side drainage groove 47.

  Here, the drainage groove 33 is inclined so that the vehicle inner side and the vehicle outer side descend with respect to the central part in the width direction of the vehicle, and the central part is between the first vertical wall 31 and the second vertical wall 32. A ridge line 33a extending linearly in the front-rear direction is formed. Accordingly, the water that has fallen into the drainage groove 33 on the inside and outside of the vehicle across the ridge 33a is basically discharged to the first housing side drainage groove 46 and the second housing side drainage groove 47, respectively. 33. That is, the inner end and the outer end of the drainage groove 33 form drainage ports 33b and 33c of the drainage groove 33, respectively.

  In addition, the second vertical wall 32 that defines the rear end of the drainage groove 33 is curved in a substantially arc shape following the outer shape of the corner of the movable panel 13, but the first vertical wall 31 that defines the front end of the drainage groove 33 is a vehicle. It extends substantially linearly in the width direction. That is, the drainage groove 33 is gradually expanded toward the vehicle outer side by the extent that the first vertical wall 31 extends substantially linearly. This is because, for example, if the first vertical wall 31 is curved in a substantially arcuate shape following the outer shape of the corner of the movable panel 13, the center of the support bracket 21 is rotated when the movable panel 13 is tilted up. This is because the vehicle outer portion rises with respect to the vehicle inner portion of the drainage groove 33 by the distance. In this case, the water that has fallen into the drainage groove 33 is discharged only from the vehicle inner side (drainage port 33b), and drainage performance is inevitably deteriorated. The said shape of the 1st vertical wall 31 forms the suppression part 34 which suppresses that the water which fell to the drain groove 33 is biased and discharged | emitted by the drain outlet 33b.

Next, the operation of this embodiment will be described.
The water dropped from the front edge of the movable panel 13 above the guide groove 41 is guided by the drainage groove 33 in the vehicle width direction toward both the first housing side drainage groove 46 and the second housing side drainage groove 47. . For this reason, it is suppressed that the water which fell from the front edge part of the movable panel 13 wets the functional component 20 in the guide groove 41. FIG.
