SUNROOF UNIT

Increase of an overall thickness of a sunroof unit is suppressed even when a flange portion depending from a side edge of an opening of a roof has a large height. A rear panel 12 contacts an edge of an opening 3 via a rear seal portion 18. The rear seal portion 18 includes a first seal member 31 mounted to a rear molded part 17 in a rear portion of the opening 3 and a second seal member 32 extending in a fore and aft direction and supported by a frame 20 via a support bracket 33 to form a passage for a stay 63 between the second seal member and the rear molded part 17 in a side portion of the opening 3. The frame 20 includes a pair of guide walls 41 disposed more inboard than a side edge of the opening 3 and slidably guiding the slider 40 in the fore and aft direction and a vertical wall 43 formed to stand upright at a position more outboard than the side edge of the opening 3. The support bracket 33 has a U-shaped cross section opened upward and is disposed to receive a flange portion 4 depending from the side edge of the opening 3.
