A linear reinforcing part is provided in the intersecting direction, and fixing means for attaching the sunroof frame to the vehicle body is arranged on the reinforcing part or an extension line of the reinforcing part.

  According to the first aspect of the present invention, the force in the closing direction and the opening direction applied to the corner portion of the opening portion provided in the roof panel is effectively reduced by the linear reinforcing portion provided in the corner portion of the sunroof frame. As a result of increasing the rigidity of the roof panel, the rigidity of the vehicle body can be increased. In addition, the sunroof described in this specification is a window provided on the ceiling of the vehicle body, and is generally a portion corresponding to a lid of an opening called a sunroof, moon roof, panorama roof, or multi roof Includes those that open and close, those that are fixed, and those that have a plurality of openings.

  The present invention according to claim 2 is characterized in that the reinforcing portion is formed by a step in the height direction of at least one of the vehicle body bodies provided in the sunroof frame, so that the weight of the vehicle is increased. It is possible to increase the rigidity of the roof panel without increasing the cost.

  The present invention according to claim 3 is characterized in that the reinforcing portion is provided at all corner portions formed by all of the front, rear, left and right frame portions of the sunroof frame. In all corner portions formed by the left and right frame portions, it is possible to further increase the rigidity of the roof panel against the force in the closing direction and the opening direction.

  According to a fourth aspect of the present invention, the reinforcing portion is configured as a part of a step portion formed in each of the front, rear, left and right frame portions of the sunroof frame. Therefore, it is possible to omit the process of processing only the reinforcing portion, and it is possible to suppress an increase in cost.

  The invention according to claim 5 is characterized in that the sunroof panel is fixed to the outer peripheral side and the inner peripheral side with an adhesive at at least a part of the frame portion forming the sunroof frame. The larger force applied to the frame can be received, and the rigidity of the vehicle can be increased.

  According to the present invention, in a vehicle with a sunroof, the rigidity of the roof panel can be further increased while suppressing an increase in the weight and cost of the vehicle.
