Description Titre de l'invention : VEHICLE ROOF STRUCTURE AND DE- CORATION FILM, AND DECORATION FILM AFFIXING METHOD Domaine technique 100011 The present invention relates to a vehicle roof peripheral structure, a vehicle roof de- coration film, a mobile abject equipped with a vehicle roof decoration film, and a decoration film affixing method. Technique antérieure [0002] As an exterior material of an automobile, a rail road vehicle, aircraft, etc., there are employed synthetic resin decoration films of various designs (hereinafter sometimes referred to as decoration films). By employine a decoration method in which a decoration film is affixed to the outer surface of an automobile or the like, it is possible to easily impart an freely chosen design as the exterior of an automobile or the like. The decoration film can be peeled off without damaging the actual exterior member of an automobile or the like, and allows re-affixine. [0003] As for such decoration films, as disclosed, for example, in Patent Literature 1, a de- coration film having an adhesion layer is known. The decoration film of this example has a skin layer, a decoration layer, and an adhesion layer, and, further, an adhesion layer protective sheet (separator) is affixed to the adhesion layer. [0004] On the other hand, the decoration film may be applied to the exterior of an au- tomobile or the like for the purpose, for example, of achieving improvement in terms of outward appearance. By affixine the decoration film to the exterior, it is possible to improve the strength of the surface of the vehicle body, to impart a complicated design thereto, etc. Problème technique [0005] In the case, however, in which an adhesion layer is provided on the decoration film as in the abovementioned example, deterioration in Ilexibility occurs as compared with the case of a single-layer decoration film. On the other hand, in many cases, the exterior of an automobile to which such a decoration film is affixed has a complicated three-dimensional configuration. [0006] Furthermore, in the case in which fo= is not imparted to the decoration film be- forehand, in a portion in which affixation to a vehicle portion is difficult due to a threedimensional configuration, the affixation tinte increases if the affixation is to be executed so as not to generate an exposed portion. For example, at a corner portion of an end portion of a vehicle body panel member constituting the object to which the 2 film is to be affixed, the affixation lime is rather long since the affixation has to be performed without involving exposure of the panel material. Thus, when a decoration film is to be bonded to a roof panel, there is room for improvement if the decoration film is to be bonded with a satisfactory outward appearance without involving deterioration in bowling strength, [0007] The present invention has hem made with a vicw ta solving the above-mentioned problcm. Tt is an abject of the present invention to facilitatc the operation of affixing a decoration film ta, for example, a corner portion of a vehicle roof panel without involving exposure of a panel member. Solution technique [0008] To achieve the abovementioned object, there is providcd, in accordance with the present invention, a vehicle roof peripheral structure including a roof panel ta which a decoration film is affixed, and a roof molding arranged on either side in the vehicle width direction of the roof panel. In the vehicle roof peripheral structure, at cach of a front portion and a rcar portion of the decoration film, there is providcd a lower affixation allowance portion bent toward the vehicle lower sicle and affixcd ta cach of the front portion and the rear portion of the roof panel; at an miter side portion in the vehicle width direction of the decoration film, there is providcd a lateral affixation flap bent toward the vehicle lower side and affixcd to a sicle portion in the vehicle width direction of the roof panel; and there is providcd a corner portion formed by the lateral affixation flap and the lower affixation flap, and the corner portion is affixcd to an outer side portion in the vehicle width direction of the roof panel. [0009] For example, the roof molding has a base portion cxtending along a vehicle front-rcar direction, and a head portion protruding to both sicles in the vehicle width direction from an upper portion of the base portion; the outer side portion in the vehicle width direction of the roof panel is provided with a contact portion with which a vehicle lower side of the head portion of the roof molding is held in contact; and the outer side portion in the vehicle width direction of the decoration film is held between the contact portion and the head portion, and an outer side end in the vehicle width direction of the latentl affixation allowance portion is ai-ranged on the outer side in the vehicle width direction of the contact portion. [0010] For example, a lip portion protruding to bath sides in the vehicle width direction is provided at the lower portion of the base portion of the roof molding; and the outer side end in the vehicle width direction of the lateral affixation allowance portion is arranged between the contact portion and the lip portion. [0011] For example, the corner portion is provided with a cutout cut to an inner side in the vehicle width direction. 3 [0012] For example, the cutout has a front edge portion extending to the miter side in the vehicle width direction from a bottom portion, and a rear edge portion arranged at a vehicle rear sicle of the front edge portion and extending to the miter sicle in the vehicle width direction from the bottom portion; the bottom portion is providcd at a position corresponding to a front end or a rear end of the roof panel; one of the front edge portion and the rear edge portion is providcd at the corner portion; the othcr is providcd at a position corresponding to the front end or the rear end or at the latcral affixation allowance portion; and in a state in which the laierai affixation allowance portion and the lower affixation allowance portion arc affixcd to the roof panel, the portion in which the front edge portion is overlapped on the rear edge portion is covered with the roof molding. [0013] For example, the othcr of the front edge portion and the rear edge portion extends in the vehicle width direction at a position corresponding to the front end or the rear end of the roof panel. [0014] There is providcd a vehicle roof decoration film affixcd to a vehicle roof panel, such that cach of a front portion and a rear portion of the decoration film is providcd with a lower affixation allowance portion lient toward a vehicle lower sicle and affixcd to cach of a front portion and a rear portion of the roof panel, that an outer side portion in a vehicle width direction of the decoration film is provided with a lateral affixation allowance portion bent toward the vehicle lower side and affixed to a side portion in the vehicle width direction of the roof panel, and that there is provided a corner portion formed by the lateral affixation allowance portion and the lower affixation allowance portion. [0015] For example, the corner portion situated at the front portion of the decoration film is arranged on the vehicle front side of the front end of the roof panel; and the corner portion situated at the rear portion of the decoration film is arranged on the vehicle rear side of the rear end of the roof panel. [0016] For example, the corner portion is provided with a cutout cut to an inner side in the vehicle width direction; the cutout has a front edge portion extending to the outer side in the vehicle width direction from a bottom portion, and a rear edge portion arranged at a vehicle rear side of the front edge portion and extending to the outer side in the vehicle width direction from the bottom portion; the bottom portion is provided at a position corresponding to a front end or a rear end of the roof panel; one of the front edge portion and the rear edge portion is provided at the corner portion; the other is provided at a position corresponding to the front end or the rear end or at the lateral affixation allowance portion; and in a state in which the latcral affixation allowance portion and the lower affixation allowance portion arc affixed to the roof panel, the portion in which the front edge portion is overlapped on the rear edge portion is covcred with the roof molding. [0017] For example, the other of the front edge portion and the rear edge portion extcnds in the vehicle width direction at a position corresponding to the front end or the rear end of the roof panel. [0018] For example, the corner portion is providcd with a protrusion protruding to the outer side in the vehicle width direction. [0019] For example, a part of the protrusion situated at the front portion of the decoration film protrudes to the vehicle front side beyond a line which is an extension to the outer side in the vehicle width direction of the front end of the lower affixation allowance portion situated at the front portion; and a part of the protrusion situatcd at the rear portion of the decoration film protrudcs to the vehicle rear side beyond a lino which is an extension to the outer side in the vehicle width direction of the rear end of the lower affixation allowance portion situatcd at the rear portion. [0020] For example, the front end of the protrusion situatcd at the front portion of the de- coration film is curved toward the outer side in the vehicle width direction [rom the vehicle front side; and the rear end of the protrusion situated at the rear portion of the decoration film is curved toward the outer side in the vehicle width direction from the vehicle rear side. [0021] For example, at the rear portion of the protrusion situated at the front portion of the decoration film, there is provided a front side recess recessed toward the vehicle front side; and at the front portion of the protrusion situated at the rear portion of the decoration film, there is provided a rear side recess recessed toward the vehicle front side. [0022] There is provided a mobile object such that it is equipped with a vehicle roof peripheral structure as above or a vehicle roof decoration film as above.

The boundary between the top surface affixation portion 41 and the lateral affixation allowance portion 44 of the decoration film 40 of this example is situated at the corner portion formed by the medium step surface 13 and the sicle wall surface 14 of the roof panel 10. The lateral affixation allowance portion 44 is affixed while caught between the sicle wall surface 14 at the outer sicle portion in the vehicle width direction of the roof panel 10 and the roof molding 30. [0053] -In the state in which the lateral affixation allowance portion 44 is affixed to the side wall surface 14, the rear side cutout 50 is situated at the rear portion of the side wall surface 14 of the roof panel 10, and the front side cutout is situated at the front portion of the side wall surface 14 of the roof panel 10. The outer side portion in the vehicle width direction of the rear sicle lower affixation allowance portion 47 is affixed to the side wall surface 14 whilc overlapping the lateral affixation allowance portion 44 via the rear side cutout 50. Likc the rear side lower affixation allowance portion 47, the outer side portion in the vehicle width direction of the front sicle lowcr affixation allowance portion is also affixed to the sicle wall surface 14 while overlapping the lateral affixation allowance portion 44 via the front sicle cutout. [0054] Here, the configuration of the cutouts will be described. As shown in Fig. 4, the rear side cutout 50 is substantially of a triangular configuration, and bas a bottom portion 51, a front edge portion 52, and a rear edge portion 53. The bottom portion 51 is situated at the inncr sicle end in the vehicle width direction of the rear sicle cutout 50, corresponds to the rear end 11 a of the roof top surface 11, and is arranged ncar the boundary between the lateral affixation allowance portion 44 and the top surface affixation portion 41. The position in the vehicle front-rear direction of the rear end 11 a and the position in the vehicle front-rear direction of the bottom portion Si substantially coincide with each othcr. The front edge portion 52 extends toward the miter sicle in the vehicle width direction from the bottom portion 51. The rear edge portion 53 is arranged on the vehicle rear side with respect to the front edge portion 52, and extends toward the outer sicle in the vehicle width direction from the bottom portion 51. [0055] Although not shown, like the rear side cutout 50, the front side cutout is substantially of a triangular configuration, and has a bottom portion, a front edge portion, and a rear edge portion. The bottom portion is situated at the inner sicle end in the vehicle width direction of the front sicle cutout, and is arranged so as to correspond to the front end of the roof top surface 11. The front edge portion extends toward the outer sicle in the vehicle width direction from the bottom portion. The rear edge portion is arranged on the vehicle rear side with respect to the front edge portion, and extends toward the outer side in the vehicle width direction from the bottom portion. [0056] In the present embodiment, one of the front edge portion and the rear edge portion is provided at a corner portion, and the other is provided at a position corresponding to the front end or the rear end lia, or at the lateral affixation allowance portion 44. [0057] As shown in Fig. 4, the rear edge portion 53 of the rear sicle cutout 50 of the present embodiment is provided at the rear sicle corner portion 49, and is inclined toward the vehicle rear side as it extends toward the outer side in the vehicle width direction. The 11 front edge portion 52 of the rear side cutout 50 is providcd at a position corresponding to the rear end 11 a of the roof top surface 11, and extends in the vehicle width direction. Likc the rear side cutout 50, the front side cutout has its front edge portion at the front side corner portion. The rear edge portion k provided at a position corresponding to the front end of the roof top surface 11, and cxtends in the vehicle width direction. [0058] Duc to this structure, in the state in which the lateral affixation allowance portion 44 and the rear side lower affixation allowance portion 47 arc affixcd to the side wall surface 14 and the rear wall surface 17 of the roof panel 10, the portion in which the front edge portion 52 is overlapped on the rear edge portion 53 of the rear side cutout 50 is arranged on the side wall surface 14 situated between the outcr side portion in the vehicle width direction of the top surface affixation portion 41 of the roof panel 10 and the roof molding 30. In this example, the ovcrlapping portion is covered with the roof molding 30. [0059] Although not shown, in the state in which the lacerai affixation allowance portion 44 and the front side lower affixation allowance portion arc affixed to the side wall surface 14 and the front wall surface of the roof panel, the portion in which the front edge portion is overlapped on the rear edge portion of the front side cutout is arranged on the side wall surface 14 situated bctween the outer side portion in the vehicle width direction of the top surface affixation portion 41 and the roof molding 30, and is covered with the roof molding 30. [0060] By atTixing the decoration film 40 as describect above, the latere affixation allowance portion 44, etc. of the side portion in the vehicle width direction of the decoration film 40 are covered with the roof molding 30 and are hidden, so that it is possible to achieve an improvement in tenus of appearance quality (outward appearance). Furthermore, by providing a cutout in the lateral affixation allowance portion 44, it is possible to prevent generation of wrinkles in the portion in which the rear side lower affixation allowance portion 47 or the front side affixation allowance portion is overlapped on the lateral affixation allowance portion. As a result, it is possible to secure sufficient adhesion strength and to prevent defective peeling. Furthermore, when mounting the roof molding 30 to the groove portion 29, the roof molding 30 is caught by a wrinkle, whereby it is possible to suppress deterioration in operational efficiency in the operation of mounting the roof molding 30. [0061] Furthermore, the overlapping flaps of the lateral affixation allowance portion 44 of the decoration film 40 and the rear side lower affixation allowance portion 47 and the front side lower affixation allowance portion can be reliably situated on the inner side of the roof molding 30. Furthermore, even in the case in which, as shown in Fig. 9, the cutout angle is large and in which the front edge portion 52 and the rear edge portion 12 53 arc affixcd at an interval to farm no overlapping flaps, the interval can be rcliably arrangcd on the inner side of the roof molding 30. [0062] By thug forming the rcar side cutout 50 and the front side cutout, it is possible for the length in the vehicle front-rcar direction of the lateral affixation allowance portion 44 to correspond to the length in the vehicle front-rcar direction of the sicle wall surface 14 of the roof panel 10. As a result it is possible to secure the adhcsion arca for the roof panel 10 to the side wall surface 14. It is possible to prevent the front edge portion 52 and the mar edge portion 53 of the cutout from traversing the interval between the side wall surface 14 and the roof top surface 11, and when bending the rcar side corner portion 49 to affix it to the lateral affixation allowance portion 44 in a superimposed manncr, it is possible to suppress generation of wrinkles. [0063] As show in Fig. 2, in the present embodiment the vehicle lower side of the inner sicle head portion 32b of the roof molding 30 abuts the inner sicle contact portion 13a providcd on the medium step surface 13 of the roof panel 10 via the outer sicle portion in the vehicle width direction of the decoration film 40. Furthermore, the vehicle lower side of the outer side hcad portion 32a of the roof molding 30 dircctly abuts the outcr side contact portion 23a providcd on the medium step surface 23 of the roof side enter panel 20. [0064] As shown in Fig. 2, in the present embodiment the outer side portion in the vehicle width direction of the top surface affixation portion 41 of the decoration film 40 is held between the inner side contact portion 13a and the inner side head portion 32b of the roof molding 30, and the outer side end in the vehicle width direction of the lateral affixation allowance portion 44 is situated on the outer side in the vehicle width direction of the inner side contact portion 13a. By thus affixing the decoration film 40, a gap is generated between the inner side head portion 32b of the roof molding 30 and the inner side contact portion 13a of the roof panel 10 and the outer side end in the vehicle width direction of the decoration film 40, and it is possible to suppress deterioration in appearance quality through exposure of a part of the outer surface of the roof panel 10. [0065] As shown in Fig. 2, the outer side end in the vehicle width direction of the lateral af- fixation allowance portion 44 is arranged below the outer side contact portion 23a and above the outer side lip portion 33a. Due to this structure, when mounting the roof molding 30 to the groove portion 29, it is possible to suppress running of the outer side lip portion 33a on the decoration film 40 to cause the roof molding 30 to be raised. [0066] Next, the procedures for affixing the lateral affixation allowance portion 44 and the rear side lower affixation allowance portion 47 of the decoration film 40 to the roof panel 10 will be described with reference to Figs. 5 and 6. First, as shown in Fig. 5A, the top surface affixation portion 41 of the decoration film 40 is affixed to the roof top surface 11 of the roof panel 10. Next, as shown in Fig. 5B, the lateral affixation 13 allowance portion 44 of the decoration film 40 is bent toward the vehicle lower side, and affixed to the side wall surface 14 of the side portion in the vehicle width direction of the roof panel 10. Furthermore, as shown in Fig. 5C, the rear side lower affixation portion 47 of the decoration film 40 is lient toward the vehicle lower side at the rear end 11 a of the roof top surface 11 of the roof panel 10 and affixed to the rear wall surface 17. At this time, the front side affixation portion is also bent toward the vehicle lower side at the front end of the roof top surface 11 and affixed to the front wall surface. Furthermore, the rear sicle corner portion 49 is bent toward the vehicle front sicle. The front sicle corner portion is also bent toward the vehicle rear side. [0067] Next, as shown in Fig. 5D, the rear side corner portion 49 situated at the outcr sicle portion in the vehicle width direction of the rear side lower affixation allowance portion 47 is affixed to the sicle portion in the vehicle width direction of the roof panel 10 via the rear sicle cutout 50. In this example, it is affixed so as to be superimposcd on the lateral affixation allowance portion 44. Also rcgarding the front side lower affixation allowance portion, the affixation is cffected in a similar manner. As a rcsult, as shown in Figs. 6A and 6B, the front edge portion 52 is overlapped on the rear edge portion 53, and the rear edge portion 53 is affixed to the sicle wall surface 14 whilc extending in the vehicle up-down direction. Next, the roof molding 30 is tnounted to the groove portion 29 such that the lateral affixation allowance portion 44 is caught betwecn the sicle wall surface 14 of the roof panel 10 and the roof molding 30. [0068] By thus affixing the decoration film 40, it is possible to prevent generation of wrinkles at the front side corner portion formed by the front sicle lower affixation allowance portion and the front portion of the lateral affixation allowance portion 44 and at the rear side corner portion 49 fonned by the rear side lower affixation allowance portion 47 and the rear portion of the lateral affixation allowance portion 44. As a result, it is possible to secure sufficient adhesion strength and to prevent defective peeling. [0069] Subsequently, the second embodiment will be described with reference to Figs. 10 and 11. The present embodiment is a modification of the first embodiment (Figs. 1 to 9). The portions that are the same as or similar to those of the first embodiment are indicated by the same reference numerals, and a redundant description thereof will be omitted. [0070] As in the first embodiment, the decoration film 40 of the present embodiment has the front sicle lower affixation allowance portion 45, the rear sicle lower affixation allowance portion 47, and the lateral affixation allowance portion 44. The front side corner portion 46 is formed by the lateral affixation allowance portion 44 and the front sicle lower affixation allowance portion 45, and the rear side corner portion 49 is formed by the lateral affixation allowance portion 44 and the rear sicle lower affixation 14 allowance portion 47. As shown in Fig. 10, the front side corner portion 46 k situated at the front portion of the dccoration film 40, and, at the outer side portion in the vehicle width direction, is arranged on the vehicle front side of the front end 11h of the roof panel 10. As shown in Fig. 11, the rcar side corner portion 49 is situatcd at the rear portion of the dccoration film 40, and, at the outer sicle portion in the vehicle width direction, is arrangcd on the vehicle rear side of the rear end 11 a of the roof panel 10. [0071] As shown in Fig. 10, the front side corner portion 46 is provided with a front side protrusion 55 protruding to the outer sicle in the vehicle width direction. The front side protrusion 55 protrudes to the outer side in the vehicle width direction from the outcr side portion in the vehicle width direction of the front sicle corner portion 46, and the end in the vehicle width direction of the front side protrusion 55 is tapercd. Phantom line Ll in Fig. 10 indicatcs an imaginary line extending along the vehicle width direction from the front end of the intermediate portion in the vehicle width direction of the front side lower affixation allowance portion 45 of the decoration film 40. The front end is inclincd toward the vehicle rear side as it extcnds toward the outer side in the vehicle width direction from the center in the vehicle width direction of the decoration film 40. A part of the front end 55a of the front side protrusion 55 protrudes to the vehicle front sicle beyond line Ll which is an extension of the front end of the front side lower affixation allowance portion 45. [0072] The front end 55a of the front side protrusion 55 is curved toward the outer side in the vehicle width direction from the vehicle front sicle. In this example, the fi-ont end 55a of the front sicle protrusion 55 is curved so as to protrude toward the vehicle front sicle, and is curved toward the vehicle rear sicle as it extends toward the outer side in the vehicle width direction. Furthermore, at the rear portion of the front sicle protrusion 55, there is provided a front sicle recess 56 recessed toward the vehicle front side. In this example, the distal end in the vehicle width direction of the front sicle protrusion 55 is pointed, and it is concave with a radius of curvature toward the vehicle front sicle between the distal end and the lateral affixation allowance portion 44. [0073] On the other hand, as shown in Fig. 11, at the rear side corner portion 49, there is provided a rear side protrusion 57 protruding to the outer sicle in the vehicle width direction. The rear sicle protrusion 57 protrudes toward the outer sicle in the vehicle width direction from the outer sicle portion in the vehicle width direction of the rear sicle corner portion 49. The width in the vehicle front-rear direction of the rear sicle protrusion 57 is set to be larger on the outer sicle in the vehicle width direction than on the inner sicle in the vehicle width direction of the rear side protrusion 57. PhantomuMe L2 in Fig. 11 indicates an imaginary line which is an extension to the outer sicle in the vehicle width direction of the rear end of the intermediate portion in the vehicle width direction of the rear sicle lower affixation allowance portion 47 of the roof panel 10. A part of the rear end 57a of the rear side protrusion 57 protrudcs toward the vehicle rear side beyond une L2 which is an extension of the rear end of the rear sicle lower affixation allowance portion 47. [0074] Furthermore, the rear sicle protrusion 57 is curvcd toward the outer sicle in the vehicle width direction from the vehicle rear sicle of the rear end 57a. In this example, the rear end 57a of the rear side protrusion 57 is curved so as to protrudc toward the vehicle rear side, and is curvcd toward the vehicle front side as it extends toward the outer side in the vehicle width direction. [0075] The front portion of the rear side protrusion 57 is provided with a rear side recess 58 recessed toward the vehicle rear side. In this example, the distal end in the vehicle width direction of the rear sicle protrusion 57 is curved so as to be convcx toward the outer side in the vehicle width direction. it is inclincd whilc curvcd toward the inner side in the vehicle width direction as it cxtends toward the vehicle front side from the distal end, and is inclincd to the vehicle rear side as it extends toward the inner side in the vehicle width direction from the front end of the inclincd portion, extending to the intermediate portion in the vehicle width direction of the rear side protrusion 57. it forms an arc swollen toward the inner side in the vehicle width direction from the intermediate portion, and is connected to the lateral affixation allowance portion 44. At this timc, the inner side end in the vehicle width direction of the arc is situatcd on the inner side in the vehicle width direction of the miter side end in the vehicle width direction of the lateral affixation allowance portion 44. [0076] As in the first embodiment, in the state in which the decoration film 40 of the present embodiment is installed on the roof top surface 11 of the roof panel 10, the lateral affixation allowance portion 44 is bent toward the vehicle lower sicle, and affixed to the sicle wall surface 14 of the side portion in the vehicle width direction of the roof panel 10, and each of the front sicle lower affixation allowance portion 45 and the rear sicle lower affixation allowance portion 47 is bent toward the vehicle lower sicle and affixed at each of the front portion and the rear portion of the roof panel 10, and the front skie corner portion 46 and the rear sicle corner portion 49 are affixed to the sicle wall surface 14 of the side portion in the vehicle width direction of the roof panel 10. At this time, the roof molding 30 is mounted such that the outer sicle portion in the vehicle width direction of the decoration film 40 is caught between the sicle wall surface 14 of the roof panel 10 and the roof molding 30 extending in the vehicle front-rear direction. [0077] Fm-thermore, in the present embodiment, when the front side corner portion 46 and the rear sicle corner portion 49 are affixed to the sicle wall surface 14 of the roof panel 10 so as to be caught therein, the front sicle corner portion 46 and the rear sicle corner portion 49 serve as grasping flaps that can be grasped by the worker. By securing the grasping flaps, it is possible to achieve an improvement in terms of operational ef- 16 ficiency. Furthermore, in the present embodiment, the corner portions 46 and 49 arc respectively provided with the front side protrusion 55 and the rcar sicle protrusion 57, so that it is possible to secure sufficicnt grasping flaps and to achieve an improvement in ternis of operational cfficiency. [0078] Furthermore, in the present embodiment, the front sicle corner portion 46 (the front side protrusion 55) is situatcd on the front side of the outer side portion in the vehicle width direction of the front end 11h of the roof panel 10, and the rcar side corner portion 49 (the rcar side protrusion 57) is situated on the rear sicle of the outer side portion in the vehicle width direction of the rcar end 11 a of the roof panel 10, so that when affixing the lateral affixation allowancc portion 44 to the side wall surface 14 of the roof panel 10, it is possible to suppress a rcduction in adhesion strcngth as a requit of the adhcsion surfaces of the corner portions 46 and 49 including the protrusions 55 and 57 coming into contact with the side wall surface 14 of the roof panel 10, making it possible to achieve an improvement in terms of workability. In particular, atter the affixation of the rcar side corner portion 49, the rcar side protrusion 57 can be eut off, SC) that it is possible to further suppress a rcduction in the adhcsion force mentioned abovc. In this example, it is eut off along line L3 indicated in Fig. 11. [0079] Furthermore, in the present embodiment, a part of the front end 55a of the front sicle protrusion 55 protrudcs to the vehicle front side beyond line Ll, and a part of the rear end 57a of the rear sicle protrusion 57 protrudcs to the vehicle rear side beyond line L2, so that even in the case in which affixation is to be effected to a corner R portion formed by the sicle wall surface 14 and the front wall surface 16 or the rear wall surface 17 of the roof panel 10, it is possible to secure a sutTicient adhesion surface. Furthennore, the front end 55a of the front sicle protrusion 55 and the rear end 57a of the rear sicle protrusion 57 are curved, whereby, as compared with the case in which a discontinuous portion is provided, grasping with fingers is facilitated during work, and an improvement in terms of workability is achieved. Furthennore, due to the provision of the front side recess 56 and the rear side recess 58, it is possible to secure a sufficient grasping tlap.
