The opening width S can be increased.

  3 to 5 show the top load sunroof structure of Example 2 according to the embodiment of the present invention.

  The same or equivalent parts as in the first embodiment will be described with the same reference numerals.

  First, the differences in configuration will be mainly described. The top load sunroof structure of the second embodiment is an upper surface portion of a side roof outer reinforcement panel 37 provided on the roof portion 32 of the vehicle body 31 as shown in FIG. 37b is formed in the body side outer panel 39 and the side roof outer reinforcement panel 37 above the closed cross section 35, and has mounting holes 39 extending vertically through the inside and outside of the closed cross section 35. A plurality are formed by placing

  In the top load sunroof structure according to the second embodiment, the inward flange portion 36a of the side roof inner panel 36 and the inward flange portion 37a of the side roof outer reinforcement panel 37 are further attached to the outside of the vehicle body. Together with the inward flange portion 34a of the body side outer panel 34 located on the outer surface, the flange portion 38 is formed by being superposed in the vertical direction and joined at the periphery of the roof panel opening 24.

  The position of the inward flange portion 34a of the flange portion 38 is formed to be lower than the upper surface portion 37b.

  Further, a drainage groove 5b formed in the roof panel unit 5 is formed one step lower than the upper surface portion 37b.

  The drain groove 5b is positioned above the flange portion 38, the drain groove 5b forming position lower surface side 5c of the roof panel unit 5, and the inward flange portion 34a of the body side outer panel 34 of the flange portion 38. As shown in FIG. 4, when a load input F is applied to the side of the vehicle body 31 as shown in FIG. 4, the side roof portion 33 from the normal position indicated by the two-dot chain line in FIG. The flange portion 38 is set so as to contact the lower surface side 5c during the deformation.

  Next, the operation of the top load sunroof structure of the second embodiment will be described.

  In the top load sunroof structure of the second embodiment configured as described above, in addition to the function and effect of the first embodiment, the position of the inward flange portion 34a of the flange portion 38 further sets the flange portion 38 low. Therefore, it is formed to be lower than the upper surface portion 37b.

  For this reason, since the drainage groove 5b formed in the roof panel unit 5 can be formed one step lower than the upper surface portion 37b, the drainage groove 5b can be brought close to the mounting holes 39.

  Therefore, the dimension W5 from the mounting hole 39 shown in FIG. 3 to the side edge of the drainage groove 5b shown in FIG. 3 is lower than the dimension W4 from the mounting hole 29 shown in FIG. 2 to the side edge of the drainage groove 5b.
