  A typical configuration of a vehicle roof structure according to an embodiment of the present invention is a vehicle roof structure provided with an air conditioner disposed on a vehicle cabin side of the vehicle roof. The vehicle roof structure further includes a vehicle on both sides of the roof. A pair of side body panels extending in the front-rear direction and constituting a vehicle body, a roof member interposed between the pair of side body panels, and a pair of braces interposed between the pair of side body panels and the roof member The air conditioner includes a main body portion and a pair of extension portions extending from the main body portion to the outside in the vehicle width direction, and each of the pair of braces overlaps the side body panel and is fixed to the side body panel. And an extended portion of the roof member and the air conditioner, and an overlapping roof member and a second piece fixed to the extended portion.

  According to the above configuration, the side body panel and the roof member are connected by the brace, and the second piece of the brace that is fixed to the roof member overlaps the roof member and the extension of the air conditioner and is fixed to these. . For this reason, the heavy load of the air conditioner is transmitted not only from the roof member to which the extension of the air conditioner is fixed, but also from the second piece of the brace to the first piece, and further to the side body panel. Is done. Therefore, the load of the air conditioner can be distributed not only to the roof member but also to the side body panel, and the air conditioner can be stably supported.

  The first piece includes a first fixing point and a second fixing point which are fixed to the side body panel and are separated from each other in the vehicle front-rear direction. The second piece is a first fixing point and a second fixing point in the vehicle front-rear direction. It is good to include the 3rd fixed point which is located between and fixed to the extension part of a roof member and an air conditioner.

  Here, the air conditioner that is a heavy object has an extension extending in the vehicle width direction from the main body, and therefore tends to oscillate around the central axis along the vehicle width direction. In the above configuration, the brace forms a triangular shape with the first fixed point of the first piece, the second fixed point, and the third fixed point of the second piece as viewed from below. Moreover, since the extension part of the air conditioner is fixed at the third fixed point of the second piece, the central axis along the vehicle width direction passes through the third fixed point or the vicinity thereof. For this reason, the load accompanying the swing around the central axis of the air conditioner is surely received at the first fixed point and the second fixed point of the first piece separated in the vehicle longitudinal direction so as to straddle the third fixed point of the second piece. Can receive. Therefore, shaking of the air conditioner can be prevented.

  The main body of the air conditioner overlaps the roof member, and the roof member includes a fourth fixing point that is fixed to the main body, and the fourth fixing point is separated from the second piece of the brace in the vehicle front-rear direction. It is good to have.

  Thereby, the main-body part of an air conditioner is being fixed to the roof member by the 4th fixing point of the roof member spaced apart from the 2nd piece of the brace in the vehicle front-back direction. The extension of the air conditioner is fixed to the roof member together with the second piece of brace. For this reason, the load accompanying the swing around the central axis along the vehicle width direction of the air conditioner, which is a heavy object, is reliably received by the second piece of the brace and the fourth fixing point of the roof member that are separated in the vehicle longitudinal direction. be able to. Therefore, shaking of the air conditioner can be prevented.

  The side body panel has a bulging portion that bulges inward in the vehicle width direction, and the first piece of the brace is fixed so as to overlap the bulging portion. From the above, it is preferable that the closed cross section is formed together with the brace and the roof member.

  Thereby, the closed cross-section structure by the bulging part of a side body panel, a brace, and a roof member can be formed, and rigidity can be improved. For this reason, even if the air conditioner swings in the vehicle width direction or the vehicle front-rear direction, the swing of the air conditioner can be reduced by the closed cross-sectional structure having high rigidity.
