Open roof construction for a vehicle

An open roof construction for a vehicle having a roof opening in its fixed roof, includes a frame having longitudinal guide sections, and a closure moveable by a closure operating mechanism between a closed position and an open position in which the closure is slid under the fixed roof. A drain channel is positioned under the rear edge of the roof opening at least in a closed position of the closure and is movable with a drain channel operating mechanism, which is capable of moving the drain channel in the opening direction of the closure. The drain channel operating mechanism is adapted so as to cause a relative movement between the drain channel and the closure. The relative movement may be used to move the drain channel such that the drain channel occupies less space when the closure is at its fully opened position, which leads to a saving of space within the frame.
