The guide pin 70 has a main body portion 72 having a predetermined length whose vertical direction is the axial direction, and a male screw portion 76 formed at the upper end portion of the main body portion 72. Specifically, the length of the main body portion 72 is the holes 33 and 35 described later when the first joint portion 54 and the second joint portion 58 are joined to the first joint portion and the second joint portion, respectively. The length is such that it penetrates through and protrudes downward from the lower surfaces of the under-reinforcement 32F and 32C.

Further, the lower end portion of the main body portion 72 is formed in a conical shape, and the lower end portion thereof is a tapered portion 74. The guide pin 70 is attached to the bracket 60 by screwing the male screw portion 76 into the female screw portion 66. As a result, the guide pin 70 is detachably mounted on the lower surface of the resin layer 56.

Further, in the front roof reinforcement 30F, the hole 33 as the reference portion is formed so as to penetrate in the vertical direction at the central portion in the vehicle width direction of the apparity reinforcement 36F and the underference 32F. Then, in the central portion of the flange portions 34C and 38C joined to each other at the front end portion of the roof reinforcement 30 on the central side in the vehicle width direction, the hole portion 35 as the reference portion is formed so as to penetrate in the vertical direction. ing.

The hole 33 formed in the roof reinforcement 30F on the front side is a substantially elliptical elongated hole long in the front-rear direction, and the width (inner diameter) along the vehicle width direction is the guide pin 70 (main body 72). It is said to be almost the same size as the outer diameter of. Further, the hole 35 formed in the roof reinforcement 30 on the center side is a circular fitting hole having an inner diameter substantially the same as the outer diameter of the guide pin 70 (main body 72).

Therefore, the guide pin 70 on the rear side is inserted into the hole 35 (fitting hole) from above with almost no gap, and the guide pin 70 on the front side has a gap in the hole 33 (long hole) from above in the front-rear direction. The surface layer 52 and the resin layer 56 of the main roof 50 are positioned and arranged with respect to the sub roof 40 and the roof reinforcements 30F and 30C.

Then, in the main roof 50, with the guide pins 70 inserted into the holes 33 and 35 and positioned, the first joint portion 54 and the second joint portion 58 are respectively the first jointed portion (support portion). 44 and the recess 39) and the second bonded portion (rear side flange portion 38F and front side flange portion 38C) are joined by the first adhesive G1 and the second adhesive G2.

The hole 33 is a long hole long in the front-rear direction in order to absorb an error in the position of the bracket 60 attached to the lower surface of the resin layer 56 in the front-rear direction. Further, as shown in FIG. 3, in each guide pin 70, after the first joint portion 54 and the second joint portion 58 are joined to the first joint portion and the second joint portion, respectively, each bracket 60 It is designed to be removed from.

Further, the external terminal 52B at the peripheral edge portion 52A of the surface layer 52 is a part of the upper surface of the step portion 42 of the sub roof 40, a part of the upper surface of the apparity information 36C in the roof reinforcement 30C on the center side, and the left and right weatherers 14. Along with a portion of the top surface, it is covered (sealed) by a weatherproof soft sealer S.

Since the sealer S is provided in an annular shape along the outer terminal 52B and has a high coefficient of expansion, even if the outer terminal 52B thermally expands to the front side and the rear side due to a difference in the linear expansion coefficient due to a temperature change, for example, the sealer S is provided. It is possible to follow the elongation. As a result, it is possible to prevent water from entering the vehicle interior through the gap between the outer terminal 52B and the upper surface of the step portion 42 and the gap between the outer terminal 52B and the upper surface of the apparity information 36C.

Next, the operation of the assembled structure 10 of the main roof 50 according to the present embodiment having the above configuration will be described.

First, two guide pins 70 are previously attached to the front and rear of the lower surface of the resin layer 56 of the main roof 50 at the center in the vehicle width direction. Specifically, the male screw portion 76 of each guide pin 70 is screwed into the female screw portion 66 formed on the boss portion 64 of each bracket 60 joined to the lower surface of the resin layer 56 by the double-sided tape T. back. Then, as shown in FIG. 2, the main roof 50 in this state is arranged while being positioned on the roof 12 of the vehicle.

That is, while visually inserting the guide pins 70 into the holes 33 and 35, the first joint portion 54 provided on the peripheral edge portion 52A of the main roof 50 and the second joint portion 58 provided on the resin layer 56 are inserted. It is joined to the first jointed portion and the second joined portion, respectively. Specifically, the first joint portion 54 is joined to the upper surface 44U of the support portion 44 and the upper surface 39U of the recess 39 via the first adhesive G1, and the second joint is joined via the second adhesive G2. The portion 58 is joined to the upper surface of the flange portion 38F and the upper surface of the flange portion 38C, respectively.

Here, since the lower end portion of each guide pin 70 is a tapered portion 74, each guide pin 70 is easily inserted into each of the hole portions 33 and 35. Further, each guide pin 70 inserted (positioned) into each of the holes 33 and 35 is provided in the resin layer 56 thicker than the surface layer 52. Therefore, the support rigidity of each guide pin 70 can be improved as compared with the case where each guide pin 70 is provided on the surface layer 52 thinner than the resin layer 56, for example.

In other words, when the main roof 50 (surface layer 52 and resin layer 56) is assembled to the sub roof 40 and the roof reinforcements 30F and 30C, it is possible to suppress or prevent the guide pins 70 from inadvertently moving. It is possible to suppress or prevent mispositioning of the surface layer 52 and the resin layer 56 with respect to the sub-roof 40 and the roof reinforcements 30F and 30C. Therefore, it is possible to improve the assembling property when assembling the main roof 50 (surface layer 52 and resin layer 56) to the sub roof 40 and the roof reinforcements 30F and 30C.

Further, the guide pin 70 is located between the first joint portion 54 on the front side and the second joint portion 58 on the front side, and the first joint portion 54 on the rear side and the second joint portion on the rear side when viewed from the side view from the vehicle width direction. It is provided between the joint portion 58 and the joint portion 58. Therefore, the guide pin 70 is not provided between the front first joint 54 and the front second joint 58 and between the rear first joint 54 and the rear second joint 58. Compared to the case (when the guide pin 70 is provided far away from the first joint portion 54 and the second joint portion 58), the position accuracy of the first joint portion 54 with respect to the first joint portion and the second joint portion The position accuracy of the 58 with respect to the second joint can be improved.

Further, the reference portion is a hole 33, 35 formed in the roof reinforcements 30F and 30C, respectively, and the reference portion is a guide pin 70 inserted into the holes 33, 35, respectively. Therefore, the surface layer 52 and the resin layer 56 can be easily positioned with respect to the sub-roof 40 and the roof reinforcements 30F and 30C as compared with the case where the reference portion is not the holes 33 and 35 and the reference portion is not the guide pin 70.

Further, the hole portion 35 on the rear side is a fitting hole having an inner diameter substantially the same as the outer diameter of the guide pin 70, and the hole portion 33 on the front side is a long hole long in the front-rear direction. Therefore, even if there is some error in the position of the guide pin 70 in the front-rear direction, the rear guide pin 70 is inserted into the hole 35, and the front guide pin 70 is inserted into the hole 33. That is, even if there is some error in the position of the guide pin 70 in the front-rear direction, the mispositioning of the surface layer 52 and the resin layer 56 with respect to the sub-roof 40 and the roof reinforcements 30F and 30C is suppressed or prevented.

Therefore, there is no possibility that the assembling property when assembling the main roof 50 (surface layer 52 and resin layer 56) to the sub roof 40 and the roof reinforcements 30F and 30C is hindered, and the main roof 50 (surface layer 52 and resin layer 56) is not impaired. ) Can be easily assembled to the sub-roof 40 and the roof reinforcements 30F and 30C.

Further, each bracket 60 that supports each guide pin 70 is attached to the lower surface of the resin layer 56 by an adhesive material such as double-sided tape T. Therefore, it is not necessary to provide a hole or the like for attaching each guide pin 70 on the lower surface of the resin layer 56, and the attachability of the guide pin 70 to the resin layer 56 can be improved. That is, each bracket 60 can easily provide each guide pin 70 on the lower surface of the resin layer 56.

In this way, when the main roof 50 (surface layer 52 and resin layer 56) is assembled to the sub-roof 40 and the roof reinforcements 30F and 30C (the first joint portion 54 and the second joint portion 58 are the first joint portion and the second joint portion, respectively). After being joined to the jointed portion), each guide pin 70 is removed from the bracket 60. At this time, since each guide pin 70 is attached to the boss portion 64 of the bracket 60 by screwing (screw fastening), it can be easily removed.

Therefore, when the roof head lining (not shown), which is the ceiling of the passenger compartment (a panel-shaped base material arranged so as to face the passenger compartment), is provided on the lower side of the roof reinforcements 30F and 30C. Each guide pin 70 does not get in the way. The removed guide pin 70 can be reused.

Further, since the surface layer 52 of the main roof 50 according to the present embodiment is made of resin, the weight of the vehicle can be reduced as compared with the case where the surface layer 52 is made of metal. Further, since the resin layer 56 of the main roof 50 according to the present embodiment is a foam molded body and is formed thicker than the surface layer 52, it is possible to effectively suppress the ingress of noise into the vehicle interior. Moreover, the heat insulating effect can be enhanced.

Further, since the main roof 50 according to the present embodiment is configured by integrally providing the resin layer 56 on the surface layer 52 constituting the roof panel, the resin layer is integrally provided on the roof head lining to form the roof panel. The reference portion (guide pin 70), which is a reference at the time of assembly, can be easily set as compared with the configuration of attaching to.

That is, in the case of a configuration in which the resin layer is integrally provided on the roof head lining and attached to the roof panel, the reference portion is restricted to be provided on the outer peripheral portion for visual inspection. However, this embodiment is not subject to such restrictions. Also, when replacing the wire harness (not shown) arranged between the roof panel and the roof head lining, the main roof 50 can be removed and replaced, so the roof head lining can be removed and replaced. The replacement cost is reduced as compared with the case of doing so.

The assembly structure 10 of the main roof 50 (roof member) according to the present embodiment has been described above with reference to the drawings, but the assembly structure 10 of the main roof 50 according to the present embodiment is limited to the one shown in the drawing. The design can be appropriately changed without departing from the gist of the present invention. For example, the surface layer 52 is not limited to being made of resin, and may be made of thin plate-shaped metal.

Further, the second joint portion 58 may not be provided. In this case, each guide pin 70 is removed from each bracket 60 after the first joint portion 54 is joined to the first joint portion. That is, each guide pin 70 may be removed from each bracket 60 after at least the first joint portion 54 is joined to the first joint portion.
