  • Open-top type vehicle roof structure
    Patent number: 5052743
    Abstract: An open-top roof structure is assembled by first assembling an inner panel, a reinforcing panel and an outer panel into a roof subassembly which has a roof opening to be closed with a roof lid and which is rigid enough to resist distortion. The subassembly is then joined to the front and rear pillars of the vehicle body in order to improve the dimensional accuracy, the fit, and the watertightness between the roof opening and roof lid. The roof structure further includes a weather strip bordering the roof opening and a roof lid locking member which are both fixed to the roof outer panel with a common bolt.
