  • Patent number: 4729597
    Abstract: A roof structure of a vehicle is composed of left and right removable roof lids, and a frame having front and rear portions, a longitudinal center beam connecting the front and rear portions, and left and right roof openings which are separated by the center beam between the front and rear portions, and closed by the left and right roof lids. Front and rear receiving members each having left and right latch holes are fixedly mounted on the center beam. Front and rear L-shaped latch plates are fixed to the underside of an inboard portion of each lid so that the front and rear latch plates are inserted in the latch holes of the front and rear receiving members, interlocking with each other, for securing the lid to the frame. Each of the receiving members further has a top wall which is formed with a stopper projection projecting upwardly.
