Description

  The present invention relates to a vehicle roof structure.

  Patent Document 1 discloses a conventional vehicle roof structure (hereinafter, simply referred to as a roof structure). This roof structure includes a vehicle body, a base panel, an opening / closing panel, a first weather strip, and a second weather strip.

  The base panel is fixed to the vehicle body. The base panel has an opening communicating with the vehicle interior. The open / close panel is formed in a plate shape. The opening / closing panel is movably provided on the base panel and can open and close the opening. Although the details are unknown in the document, such a roof structure is generally provided with an opening / closing mechanism for moving the opening / closing panel.

The first and second weather strips can be sealed between the outside of the vehicle and the inside of the vehicle by contacting the opening / closing panel.

  In this roof structure, the first and second weather strips come into contact with the opening / closing panels, respectively, so that water such as rainwater is discharged from the opening in the vehicle compartment as compared with the configuration including only the first weather strip or the second weather strip. Can be suitably prevented.

JP, 2011-51398, A

  In the above conventional roof structure, it is conceivable that the base panel is made of resin in order to realize weight reduction and easy manufacturing. However, in that case, the resin-made base panel has a larger linear thermal expansion coefficient than that of the inorganic glass or metal-made base panel, so that the resin-based base panel greatly expands and contracts due to temperature change. In this roof structure, the first and second weather strips are fixed to the base panel, so that the first and second weather strips move largely relative to the opening / closing panel as the base panel greatly expands and contracts. I will end up. As a result, the positional deviation between the first and second weather strips and the opening / closing panel becomes large, so that when the opening / closing panel closes the opening of the base panel, it is difficult for the first and second weather strips to appropriately contact the opening / closing panel. Become. As a result, with this roof structure, the space between the vehicle exterior and the vehicle interior cannot be sufficiently sealed, and water may enter the vehicle interior through the opening.

  Further, due to the large positional deviation between the first and second weather strips and the opening / closing panel, in this roof structure, when the opening / closing panel moves the base panel to open and close the opening, the first and second weather strips are It is likely to be erroneously detected as a foreign substance. As a result, this roof structure is apt to malfunction.

  The present invention has been made in view of the above-mentioned conventional circumstances, and realizes reduction in weight and simplification of manufacturing, and even when a large expansion and contraction occurs in the base panel, water does not enter the vehicle interior through the opening. It is a problem to be solved to provide a roof structure for a vehicle that can be highly reliably prevented and that can prevent the occurrence of malfunction.

The vehicle roof structure of the present invention includes a vehicle body,
A resin-made base panel fixed to the vehicle body and having an opening communicating with the vehicle interior,
A plate-shaped opening / closing panel that is movably provided on the base panel and is capable of opening and closing the opening,
An opening / closing mechanism that is provided between the vehicle body and the opening / closing panel and moves the opening / closing panel,
A plurality of weather strips located inside the opening and abutting the open / close panel to seal between the outside of the vehicle and the inside of the vehicle;
The opening / closing mechanism includes a mechanism main body to which the opening / closing panel is attached, a water receiving member attached to the mechanism main body, arranged in the opening, and capable of storing water,
The linear thermal expansion coefficient of the mechanism body and the linear thermal expansion coefficient of the water receiving member are smaller than the linear thermal expansion coefficient of the base panel,
At least one of the weather strips is attached to the water receiving member.

  In the roof structure of the present invention, since the base panel is made of resin, the weight can be reduced and the production can be facilitated as compared with the case where the base panel is made of inorganic glass or metal.

  Further, in this roof structure, the plurality of weather strips come into contact with the opening / closing panel within the opening of the base panel. Therefore, when the opening / closing panel closes the opening, the space between the outside of the vehicle and the inside of the vehicle can be suitably sealed.

  Here, in this roof structure, the opening / closing mechanism has the mechanism main body and the water receiving member, and the linear thermal expansion coefficients of the mechanism main body and the water receiving member are smaller than the linear thermal expansion coefficient of the base panel. For this reason, the mechanism body and the water receiving member are less likely to expand and contract due to temperature changes as compared to the base panel. Further, since the opening / closing panel is attached to the mechanism body, even if the opening / closing panel is made of resin, the opening / closing panel is less likely to expand and contract due to temperature change than the base panel.

  Further, since at least one of the weather strips is attached to the water receiving member, the weather strip attached to the water receiving member is unlikely to be displaced from the opening / closing panel. As a result, in this roof structure, even when the base panel greatly expands and contracts due to temperature changes, the weather strip mounted on the water receiving member and the opening / closing panel are preferably brought into contact with each other, so that the outside of the vehicle and the inside of the vehicle can be separated from each other. The space can be sealed. Further, even if water enters the opening, the water receiving member stores the water in the opening. As a result, in this roof structure, even if the base panel greatly expands and contracts, it is difficult for water to enter the vehicle interior through the opening.

  In addition, since the weather strip attached to the water receiving member is unlikely to be displaced from the opening / closing panel, the roof strip of this roof structure moves when the opening / closing panel moves the base panel to open or close the opening. It is difficult to be falsely detected as a foreign substance.

  Therefore, the vehicle roof structure of the present invention can reliably prevent the entry of water into the vehicle interior through the opening even when the base panel is largely expanded and contracted while realizing the weight reduction and the easy manufacturing. In addition, it is possible to suppress the occurrence of malfunction.

  The opening / closing panel may have a first surface facing the outside of the vehicle, a second surface located opposite to the first surface, and an end surface continuous with the first surface and the second surface. Each weather strip preferably includes a first weather strip that is annular and faces the second surface, and a second weather strip that is located on the outer peripheral side of the first weather strip and faces the end surface.

  In this case, the manufacturing of the roof structure can be facilitated by reducing the types of weather strips. In addition, the first weather strip and the second weather strip face the second surface and the end surface of the opening / closing panel, respectively, and abut against the opening / closing panel, so that the outside and the inside of the vehicle can be suitably sealed. It will be possible.

  The first weather strip and the second weather strip are preferably mounted on the water receiving member. In this case, it is possible to prevent both the first weather strip and the second weather strip from being displaced from the open / close panel when the base panel is greatly expanded and contracted. Therefore, the first and second weather strips can more appropriately seal between the outside of the vehicle and the inside of the vehicle. Here, since the second weather strip is located on the outer peripheral side of the first weather strip, the second weather strip is attached to the water receiving member while the second weather strip is the water in the water receiving member. In the flow direction of, the first weather strip is located on the upstream side.

  Also, the first weather strip may be attached to the water receiving member. The second weather strip is also preferably attached to the base panel. In this case, a space or the like for mounting the second weather strip on the water receiving member is not required, so that the degree of freedom in designing the water receiving member can be increased. On the other hand, since the first weather strip is attached to the water receiving member, it is possible to prevent the positional deviation from the open / close panel when the base panel greatly expands and contracts. Accordingly, the first weather strip can preferably contact the open / close panel.

  Here, since the second weather strip is located on the outer peripheral side of the first weather strip, the first weather strip is located downstream of the second weather strip in the water flow direction of the water receiving member. As a result, even if the position difference between the second weather strip and the end surface of the opening / closing panel increases due to the expansion and contraction of the base panel, the water receiving member stores water and the first By contacting the weather strip with the opening / closing panel, it is possible to prevent water from entering the vehicle compartment through the opening.

  It is preferable that a sealing member that seals between the base panel and the water receiving member is provided between the base panel and the water receiving member while absorbing expansion and contraction of the base panel due to temperature change.

  In this case, the sealing member can preferably prevent water from entering the vehicle compartment between the base panel and the water receiving member. Here, the sealing member absorbs expansion and contraction of the base panel due to temperature change. Therefore, in this roof structure, it is possible to prevent water from entering the passenger compartment from between the base panel and the water receiving member even when the base panel expands and contracts.

  The vehicle roof structure of the present invention is capable of reliably preventing the entry of water into the vehicle interior through the opening even when the base panel is greatly expanded and contracted while realizing the weight reduction and the easy manufacturing. The occurrence of malfunction can be suppressed.

  Hereinafter, Examples 1 to 3 embodying the present invention will be described with reference to the drawings.

(Example 1)
As shown in FIGS. 1 to 3, the roof structure of the first embodiment includes a vehicle body 1, a base panel 3, an opening / closing panel 5, an opening / closing mechanism 7, an inner weather strip 9, and a first outer weather strip 11. , And a second outer weather strip 13. This roof structure is used in a vehicle and constitutes the ceiling of the vehicle body 1. The inner weather strip 9 is an example of the “first weather strip” in the present invention. The first and second outer weather strips 11 and 13 are examples of the "second weather strip" in the present invention.

  In this embodiment, the arrows shown in FIG. 1 define the front-rear direction, the up-down direction, and the left-right direction of the vehicle body 1. 2 and subsequent figures, the front-back direction, the up-down direction, and the left-right direction of the vehicle body 1 are defined in correspondence with FIG.

  As shown in FIG. 3, the vehicle body 1 has a metal body panel 1a that forms the outer shape of the vehicle and a resin interior panel 1b that forms the passenger compartment CR. The body panel 1a is formed with a communication port 1c that communicates with the inside of the vehicle compartment CR. As shown in FIG. 1, the communication port 1c has a rectangular shape in which the length in the front-rear direction is longer than the length in the left-right direction. The shape of the communication port 1c can be designed as appropriate. Further, in FIG. 1, the illustration of the interior panel 1b is omitted.

  The base panel 3 is made of a resin whose main component is polycarbonate and is colored opaque. The base panel 3 has a panel body 31. The panel body 31 is formed in a substantially rectangular plate shape whose length in the front-rear direction is longer than its length in the left-right direction so as to correspond to the communication port 1c of the vehicle body 1. The panel body 31 is formed larger than the mechanism body 71 of the opening / closing mechanism 7, which will be described later, and can cover the mechanism body 71 from above. The base panel 3 may be formed of a resin whose main component is other than polycarbonate.

  An opening 33 is formed in the panel body 31. The opening 33 has a rectangular shape and can communicate with the passenger compartment CR. As shown in FIG. 3, the base panel 3 is fixed to the vehicle body 1 while covering the communication port 1c from above by bonding the panel body 31 to the body panel 1a via the urethane adhesive layer 15. As a result, the opening 33 communicates with the vehicle compartment CR through the communication port 1c. Further, the urethane adhesive layer 15 prevents water or the like from entering the passenger compartment CR from between the panel body 31 and the body panel 1a.

  As shown in FIG. 1, the open / close panel 5 is made of resin whose main component is polycarbonate and is colorless and transparent. The open / close panel 5 has a rectangular plate shape corresponding to the opening 33 of the base panel 3. As shown in FIG. 3, the opening / closing panel 5 has a first surface 5a, a second surface 5b, and an end surface 5c. The first surface 5a faces the outside of the vehicle. The second surface 5b is located on the opposite side of the first surface 5a and faces the passenger compartment CR. The end surface 5c is continuous with the first surface 5a and the second surface 5b. A resin protective layer 17 is formed on the end surface 5c. The protective layer 17 protects the end surface 5c from the outer peripheral side, thereby preventing the end surface 5c and eventually the open / close panel 5 from being scratched or cracked. The formation of the protective layer 17 on the end surface 5c may be omitted. Further, the open / close panel 5 may be formed of a resin whose main component is other than polycarbonate, or the open / close panel 5 may be formed of an inorganic glass.

  The open / close panel 5 has a metal mounting frame 21. The mounting frame 21 is fixed to the second surface 5b by the urethane adhesive layer 19. Further, as shown in FIG. 1, the opening / closing panel 5 is provided with a frame-shaped concealing portion 23. The concealing portion 23 is formed by painting or printing black, which is an opaque color, on the second surface 5b. The concealing portion 23 prevents the mounting frame 21 and the like from being seen from the first surface 5a side. The concealing portion 23 may be formed by printing an opaque color other than black. Further, in order to facilitate the description, the protective layer 17 and the mounting frame 21 are not shown in FIG. 1, and the concealing portion 23 is not shown in FIGS. 3 to 5.

  As shown in FIG. 1, the opening / closing mechanism 7 includes a mechanism body 71 and a water receiving member 73. The mechanism main body 71 has a support frame 71a and a slide device 71b. The support frame 71a is made of metal and has a rectangular frame shape. As shown in FIG. 3, the support frame 71a is provided with a first mounting flange 711. Although not shown, a plurality of first mounting flanges 711 are provided on the support frame 71a.

  The slide device 71b is movably attached to the support frame 71a. Although not shown in detail, the slide device 71b has a slide frame, a motor, a gear mechanism, and the like, and most of them are made of metal. That is, the mechanism main body 71 is mainly made of metal. The slide device 71b is electrically connected to a controller (not shown) of the vehicle, and its operation is controlled by the controller. The controller can detect whether or not a foreign substance or the like exists between the base panel 3 and the open / close panel 5 based on the torque change in the slide device 71b.

  As shown in FIG. 2, the water receiving member 73 is made of metal and is formed in a rectangular annular shape corresponding to the opening 33 of the base panel 3. The water receiving member 73 has a water storage portion 73a which is annularly recessed. The water storage portion 73a can store the water that has entered through the opening 33. The water stored in the water storage section 73a is discharged to the outside of the vehicle body 1 through a drainage channel (not shown). As shown in FIG. 3, the deflector 25 is arranged in the water storage portion 73a. The deflector 25 can swing up and down in the water storage portion 73a.

  Further, in the water receiving member 73, a first support portion 73b is formed on the outer peripheral side of the water storage portion 73a. A locking portion 73c is formed on the first support portion 73b. The locking portion 73c has a plate shape protruding upward from the first supporting portion 73b, and extends so as to circulate around the outer peripheral side of the water storage portion 73a. Further, in the water receiving member 73, a second support portion 73d is formed on the inner peripheral side of the water storage portion 73a. The second support portion 73d is formed in a flat shape. It should be noted that the deflector 25 and the locking portion 73c are not shown in FIGS. 1 and 2 for ease of explanation.

  Further, as shown in FIGS. 1 and 2, the first support portion 73b is provided with a plurality of second mounting flanges 731. Each of the second mounting flanges 731 is arranged on the outermost peripheral side of the first support portion 73b and extends downward from the first support portion 73b.

  As shown in FIG. 3, the water receiving member 73 is attached to the support frame 71a by fastening the first attachment flange 711 and the second attachment flange 731 with the bolt 27 and the nut 29. Thus, in the opening / closing mechanism 7, the water receiving member 73 is attached to the mechanism body 71. The water receiving member 73 may be attached to the mechanism main body 71 by another method.

  Here, since the mechanism main body 71 is mainly made of metal and the water receiving member 73 is made of metal, the linear thermal expansion coefficient of the mechanism main body 71 and the linear thermal expansion coefficient of the water receiving member 73 are almost equal to each other. Are equal. The linear thermal expansion coefficient of the mechanism main body 71 and the linear thermal expansion coefficient of the water receiving member 73 are smaller than the linear thermal expansion coefficient of the resin base panel 3. The mechanism main body 71 and the water receiving member 73 may be made of materials other than metal as long as they are smaller than the linear thermal expansion coefficient of the base panel 3. Further, the linear thermal expansion coefficient of the mechanism main body 71 and the linear thermal expansion coefficient of the water receiving member 73 may be different from each other as long as the linear thermal expansion coefficient of the base panel 3 is smaller than that of the mechanism main body 71 and the water receiving member 73. And may be formed of different materials.

  As shown in FIG. 1, in the opening / closing mechanism 7, the support frame 71 a is fixed to the panel body 31 from the lower side of the base panel 3. Thereby, the opening / closing mechanism 7 is fixed to the vehicle body 1 via the base panel 3. Then, as shown in FIG. 3, in the mechanism main body 71, the opening / closing panel 5 is attached to the slide device 71 b via the attachment frame 21.

  Further, the water receiving member 73 is arranged in the opening 33 of the base panel 3. A sealing member 41 made of an elastic material such as synthetic rubber is provided between the panel body 31 and the water receiving member 73. The sealing member 41 is adhered to the panel body 31 and the first support portion 73b of the water receiving member 73 to prevent water from entering the inside of the vehicle body 1 from between the base panel 3 and the water receiving member 73. To prevent.

  The inner weather strip 9 shown in FIG. 2 is made of resin. The inner weather strip 9 is formed in a rectangular ring shape. As shown in FIG. 3, the inner weather strip 9 has a fixed portion 9a and a first seal portion 9b. The fixed portion 9a is formed in a flat shape. The first seal portion 9b is integral with the fixed portion 9a and is hollow. The inner weather strip 9 has the fixed portion 9a bonded to the second support portion 73d of the water receiving member 73 with the first seal portion 9b facing upward. In this way, the inner weather strip 9 is attached to the water receiving member 73, and is located in the opening 33 on the inner peripheral side of the water storage portion 73a. The first seal portion 9b is capable of contacting the mounting frame 21, that is, the opening / closing panel 5 while facing the second surface 5b of the opening / closing panel 5. The second support portion 73d supports the inner weather strip 9 from below.

  Like the inner weather strip 9, the first and second outer weather strips 11 and 13 shown in FIG. 2 are also made of resin. The first outer weather strip 11 extends in a substantially U shape in a top view. The second outer weather strip 13 extends linearly in the left-right direction in a top view. As shown in FIG. 3, the first outer weather strip 11 has a base portion 11a, a second seal portion 11b, a third seal portion 11c, a rib 11d, and an engagement groove 11e. The second seal portion 11b is integral with the base portion 11a and is formed hollow. The third seal portion 11c is integral with the base portion 11a on the side opposite to the second seal portion 11b, and is formed hollow. The third seal portion 11c is formed smaller than the second seal portion 11b. The rib 11d is integral with the base portion 11a and extends from the base portion 11a toward the third seal portion 11c. The rib 11d is located above the third seal portion 11c. The engagement groove 11e is recessed in the base 11a. The second outer weather strip 13 shown in FIG. 2 also has the same configuration as the first outer weather strip 11.

  As shown in FIG. 3, the first outer weather strip 11 directs the second seal portion 11b toward the water storage portion 73a side of the water receiving member 73, and the locking portion 73c of the water receiving member 73 into the engaging groove 11e. It is inserted. In this way, the first outer weather strip 11 is attached to the water receiving member 73 by fitting the locking portion 73c and the engaging groove 11e. That is, in the first outer weather strip 11, the second seal portion 11b faces the water storage portion 73a. As a result, the second seal portion 11b can come into contact with the open / close panel 5 while facing the end surface 5c of the open / close panel 5 with the protective layer 17 in between. On the other hand, the third seal portion 11c and the rib 11d are elastically deformed and are in contact with the panel body 31 in the opening 33. Similarly to the first outer weather strip 11, the second outer weather strip 13 shown in FIG. 2 is also mounted on the water receiving member 73. The second outer weather strip 13 is arranged in front of the first outer weather strip 11. Thus, the first and second outer weather strips 11 and 13 are located on the outer peripheral side of the water storage portion 73 in the opening 33 and surround the water storage portion 73a. Further, the first support portion 73b supports the first and second outer weather strips 11 and 13 from below.

  Here, the water that has entered the opening 33 flows through the water receiving member 73 from the outer peripheral side toward the inner peripheral side. That is, in this roof structure, the first and second outer weather strips 11 and 13 exist on the most upstream side in the water flow direction in the water receiving member 73. Further, the water storage portion 73a is present on the downstream side of the first and second outer weather strips 11 and 13 in the water flow direction. The inner weather strip 9 is present on the downstream side of the water storage portion 73a in the water flow direction, that is, on the most downstream side of the water receiving member 73 in the water flow direction.

  In the roof structure configured as described above, the operation of the slide device 71b of the mechanism body 71 is controlled by the controller, so that the slide device 71b moves the opening / closing panel 5 in the front-rear direction with respect to the base panel 3. Thereby, the opening / closing panel 5 can open and close the opening 33. Then, when the opening / closing panel 5 closes the opening 33, the first seal portion 9 b of the inner weather strip 9 contacts the mounting frame 21 in the opening 33. Further, the second seal portions 11b of the first and second outer weather strips 11 and 13 contact the open / close panel 5 via the protective layer 17. As a result, the first seal portion 9b and the second seal 11b seal between the outside of the vehicle and the inside of the vehicle compartment CR while elastically deforming.

  Further, in this roof structure, since the base panel 3 is made of resin, the weight reduction is realized and the manufacturing is facilitated as compared with the case where the base panel 3 is made of inorganic glass or metal. ing. In particular, in this roof structure, since the opening / closing panel 5 is also made of resin, it is possible to realize further weight reduction and easy manufacturing.

  Further, in this roof structure, in the opening 33 of the base panel 3, the first seal 9 portion 9b of the inner weather strip 9 and the second seal portion 11b of the first and second outer weather strips 11 and 13 are elastically deformed. While making contact with the open / close panel 5. Therefore, when the opening / closing panel 5 closes the opening 33, the outside of the vehicle and the inside of the vehicle compartment CR can be preferably sealed.

  Here, in this roof structure, the opening / closing mechanism 7 has a mechanism body 71 and a water receiving member 73. The mechanism body 71 is mainly made of metal, and the water receiving member 73 is made of metal. Therefore, the linear thermal expansion coefficients of the mechanism main body 71 and the water receiving member 73 are smaller than the linear thermal expansion coefficient of the base panel 3. For this reason, the mechanism main body 71 and the water receiving member 73 are less likely to expand and contract due to temperature changes as compared with the base panel 3. The open / close panel 5 is attached to the slide device 71b of the mechanism body 71. Therefore, even if the open / close panel 5 is made of resin, expansion / contraction due to temperature change is smaller than that of the base panel 3.

  Furthermore, since the inner weather strip 9 and the first and second outer weather strips 11 and 13 are both attached to the water receiving member 73, the inner weather strip 9 and the first and second outer weather strips 11 and 13 are It is not affected by the expansion and contraction of the panel 3 and is less likely to be displaced from the open / close panel 5. As a result, in this roof structure, even when the base panel 3 is greatly expanded and contracted due to temperature change, the first seal portion 9b of the inner weather strip 9 and the second seals of the first and second outer weather strips 11 and 13 are formed. By suitably contacting the opening / closing panel 5 with the portion 11b, the space between the outside of the vehicle and the inside of the passenger compartment CR can be sealed. Further, even if water enters the opening 33, the water storage portion 73 a of the water receiving member 73 stores the water in the opening 33. As a result, in this roof structure, even if the base panel 3 expands and contracts greatly, it is difficult for water to enter the vehicle compartment CR from the opening 33.

  Further, since it is difficult for the inner weather strip 9 and the first and second outer weather strips 11 and 13 to be displaced from the opening / closing panel 5, in this roof structure, the opening / closing panel 5 moves the base panel 3 to open. When opening and closing 33, the inner weather strip 9 and the first and second outer weather strips 11 and 13 are less likely to be erroneously detected as foreign matter.

  Therefore, the roof structure of the first embodiment realizes reduction in weight and simplification of manufacturing, and even when the base panel 3 largely expands and contracts, it is possible to reliably prevent water from entering the vehicle compartment CR through the opening 33. This is possible, and the occurrence of malfunction can be suppressed.

  Further, in this roof structure, the inside weather strip 9 and the first and second outside weather strips 11 and 13 seal the space between the outside of the vehicle and the inside of the passenger compartment CR, so that the type of weather strip used for the roof structure can be improved. Can be reduced. Also in this respect, this roof structure can facilitate the manufacture.

  Further, the first and second outer weather strips 11 and 13 have a third seal portion 11c and a rib 11d, and the third seal portion 11c and the rib 11d are in contact with the panel body 31 in the opening 33. .. Therefore, in this roof structure, it is possible to prevent water from entering the opening 33 through the gap between the panel body 31 and the first and second outer weather strips 11 and 13. When the base panel 3 expands or contracts due to temperature change, the third seal portion 11c and the rib 11d elastically deform accordingly. Therefore, even when the base panel 3 expands and contracts, it is possible to prevent water from entering the opening 33 through the gap between the panel body 31 and the first and second outer weather strips 11 and 13.

  Further, in this roof structure, since the sealing member 41 is formed of an elastic body such as synthetic rubber, if the base panel 3 expands or contracts due to a temperature change, the sealing member 41 and the base panel 3 are correspondingly expanded or contracted. It is possible to elastically deform with the water receiving member 73. Thereby, the sealing member 41 can absorb the expansion and contraction of the base panel 3 due to the temperature change. Therefore, in this roof structure, even if the base panel 3 expands and contracts, it is possible to prevent water from entering the inside of the vehicle body 1 from between the base panel 3 and the water receiving member 73.

(Example 2)
As shown in FIG. 4, in the roof structure of the second embodiment, the extending portion 35 is formed in the panel body 31 of the base panel 3. The extending portion 35 is integrated with the panel body 31 and is located in the opening 33. The extending portion 35 extends from the panel body 31 side toward the water storage portion 73a side of the water receiving member 73. The extending portion 35 is integrally formed with a locking portion 37 that projects upward. The locking portion 37 extends so as to go around the outer peripheral side of the water storage portion 73a. Further, a standing wall 39 is formed on the side of the extending portion 35 opposite to the panel body 31. The standing wall 39 extends into the water storage portion 73a.

  Also, in this roof structure, unlike the roof structure of the first embodiment, the third seal portion 11c and the rib 11d are not formed in the first outer weather strip 11. Then, in the first outer weather strip 11, the locking portion 37 is inserted into the engagement groove 11e while the second seal portion 11b is directed toward the water storage portion 73a side of the water receiving member 73. Thus, the first outer weather strip 11 is attached to the panel body 31 by fitting the locking portion 37 and the engagement groove 11e. Further, in the first outer weather strip 11, the base portion 11 a is brought into contact with the panel body 31. Although not shown, the second outer weather strip 13 is also attached to the panel body 31 like the first outer weather strip 11. As a result, the extending portion 35 supports the first and second outer weather strips 11 and 13 from below.

  Further, in this roof structure, the locking portion 73c is not formed on the first support portion 73b of the water receiving member 73. Further, in this roof structure, each second mounting flange 731 extends downwardly shorter than the roof structure of the first embodiment. A sealing member 43 made of an elastic material such as synthetic rubber is provided between the base panel 3 and the water receiving member 73. The sealing member 43 is bonded to the extending portion 35 and the first supporting portion 73b. The sealing member 43 prevents water from entering the inside of the vehicle body 1 from between the base panel 3 and the water receiving member 73. The other structure of this roof structure is the same as that of the roof structure of Example 1, and the same structures are denoted by the same reference numerals and detailed description thereof is omitted.

  In this roof structure, the first and second outer weather strips 11 and 13 are mounted on the panel body 31, thereby mounting the first and second outer weather strips 11 and 13 on the first support portion 73b of the water receiving member 73. The space for it is unnecessary, and the locking portion 73c is also unnecessary. As a result, in this roof structure, the degree of freedom in designing the water receiving member 73 can be increased, and the water receiving member 73 can be downsized as compared with the roof structure of the first embodiment. Is becoming Here, also in this roof structure, since the inner weather strip 9 is attached to the water receiving member 73, the positional deviation between the inner weather strip 9 and the opening / closing panel 5 due to the temperature change hardly occurs. As a result, the inner weather strip 9 can suitably contact the mounting frame 21, that is, the opening / closing panel 5.

  Here, in this roof structure, if the base panel 3 greatly expands and contracts due to temperature changes, the first and second outer weather strips 11 and 13 can move accordingly. As a result, the positional deviation between the first and second outer weather strips 11 and 13 and the end surface 5c of the opening / closing panel 5 becomes large, so that the gap between the first and second outer weather strips 11 and 13 and the opening / closing panel 5 is increased. Water may enter the openings 33. In this respect, in this roof structure, the first and second outer weather strips 11 and 13 are located on the most upstream side in the water flow direction in the water receiving member 73 when mounted on the panel body 31. As a result, even when water enters the opening 33 through the gap between the first and second outer weather strips 11 and 13 and the opening / closing panel 5, the downstream side of the first and second outer weather strips 11 and 13 is reduced. The water storage portion 73a stores the water, and the inside weather strip 9 comes into contact with the opening / closing panel 5 to seal between the outside of the vehicle and the inside of the vehicle compartment CR. Therefore, even in this roof structure, it is difficult for water to enter the vehicle compartment CR through the opening 33.

  Also in this roof structure, the expansion and contraction of the base panel 3 can be absorbed by elastically deforming the sealing member 43 when the base panel 3 expands and contracts. Therefore, also in this roof structure, the sealing member 43 can prevent water from entering the inside of the vehicle body 1 from between the base panel 3 and the water receiving member 73. Other operations in this roof structure are similar to those of the roof structure of the first embodiment.

(Example 3)
As shown in FIG. 5, in the roof structure of the third embodiment, the holding portion 73e is formed on the first support portion 73b of the water receiving member 73. The holding portion 73e projects from the first support portion 73b toward the extending portion 35 of the base panel 3. In this roof structure, the sealing member 45 is provided between the panel body 31 and the water receiving member 73.

  As shown in FIG. 6, the sealing member 45 is also formed of an elastic body such as synthetic rubber. The sealing member 45 has a main body portion 45a, a first contact rib 45b, a second contact rib 45c, and a groove portion 45d. The first contact rib 45b is integrally formed with the main body portion 45a and extends from the main body portion 45a side toward the extending portion 35 side. The second contact rib 45c is also integrally formed with the main body portion 45a. The second contact rib 45c extends from the main body portion 45a side toward the standing wall 39 side. The first contact rib 45b and the second contact rib 45c are formed thinner than the main body portion 45a. The groove portion 45d is recessed in the main body portion 45a.

  The sealing member 45 is attached to the first support portion 73b by inserting the holding portion 73e of the water receiving member 73 into the groove portion 45d. Then, in the sealing member 45, the first contact rib 45b is elastically deformed and is in contact with the extending portion 35, and the second contact rib 45c is elastically deformed and is in contact with the standing wall 39. In this way, the sealing member 45 is located between the base panel 3 and the water receiving member 73, and prevents water from entering the inside of the vehicle body 1 from between the base panel 3 and the water receiving member 73. The other structure of this roof structure is the same as that of the roof structure of the second embodiment.

  In this roof structure, when the base panel 3 expands and contracts due to temperature changes, the first and second contact ribs 45b and 45c of the sealing member 45 are elastically deformed accordingly. Here, since the first contact rib 45b and the second contact rib 45c are formed thinner than the main body portion 45a, they are easily elastically deformed. As a result, the first contact rib 45b appropriately maintains the state in which the first contact rib 45b is in contact with the extending portion 35 while absorbing expansion and contraction of the base panel 3 due to temperature change. Similarly, the second contact rib 45c appropriately maintains the state of contact with the standing wall 39 while absorbing expansion and contraction of the base panel 3 due to temperature change. Thus, in this roof structure, as compared with the roof structures of the first and second embodiments, it is possible to more reliably prevent water from entering the inside of the vehicle body 1 from between the base panel 3 and the water receiving member 73. it can. Other operations in this roof structure are similar to those of the roof structure of the second embodiment.

  Although the present invention has been described above with reference to the first to third embodiments, the present invention is not limited to the first to third embodiments, and may be appropriately modified and applied without departing from the spirit of the present invention. Needless to say.

  For example, the roof structure may be configured by appropriately combining the roof structures of the first to third embodiments.

  Further, the first seal portion 9b of the inner weather strip 9 may be in contact with the second surface 5b of the open / close panel 5.

  Further, in addition to the inner weather strip 9 and the first and second outer weather strips 11 and 13, a weather strip may be further provided in the opening 33.

  Further, the second outer weather strip 13 may be omitted by forming the first outer weather strip 11 in a shape extending in a rectangular frame shape surrounding the water storage portion 73a.
