  • Water drain structure of sunroof in vehicle
    Patent number: 10350978
    Abstract: A water drain structure of a sunroof includes a pair of guide rails disposed in a longitudinal direction of a vehicle body at both ends of a roof panel. A front drip is coupled to front ends of the pair of guide rails, the front drip having a water drain channel. An inner rail is disposed in each of the guide rails. The inner rails form a path of the sunroof at both sides from a projection formed at a center region of the guide rails in the longitudinal direction and an outer rail for keeping rainwater. A storage unit is disposed at a portion of a rear end of the outer rail and is divided into a plurality of rainwater storage spaces to keep rainwater flowing therein.
