PROBLEM TO BE SOLVED: To enhance water cut-off performance between a fixed frame and a movable window in an openable roof light window provided in such a manner that the movable window is slidable in a direction along a roof with respect to the fixed frame.SOLUTION: A water cut-off structure 50 of an openable roof light window 1 includes: a fixed frame 3 fixed to an inclined roof 2 so as to protrude and having an opening 3a; and a movable window 4 provided on the fixed frame 3 to be slidable in a direction along the roof 2. In the water cut-off structure 50, upper side eaves 51, 52 covering the fixed frame 3 from above the roof 2 are provided on an upper movable frame 8U of the movable window 4, a movable side projecting piece 51a projecting in the downward direction of the roof 2 is provided in the upper side eaves 51, 52 so as to extend over a full length of the upper edge of the opening 3a, and on an upper fixed frame 3U, a pair of fixing side projecting pieces 54, 55 projecting in the upward direction of the roof 2 is provided at a position, where they sandwich the movable side projecting piece 51a in a closed state, so as to extend over the full length of the upper edge of the opening 3a. |
