Method for the assembly of a sun roof of an automotive vehicle

摘要

The front portion of a roof panel has left-hand and right-hand roof opening sections, each roof opening section being wide open without a roof side rail on its transversely outer side. A movable roof member is mounted on the roof opening sections so as to be movable longitudinally through a base frame fixed to the body of a vehicle, thereby opening the roof opening sections when the movable roof member is moved in its rear position and closing it when it is moved in its front position. The base frame contains a front section to be mounted to a front header of the body, a rear section to be mounted to a front edge portion of a rear roof panel section, a middle section for connecting middle portions of the front section and the rear section, and a guide section extending rearward from a transversely outer side portion of the rear section. The base frame is fixed to the body in such a state that the portions of the base frame or the body where the alignment position is likely to deviate from its normal position are aligned with an aligning jig or the movable roof member. Further, an alignment section or member is formed each on the body side and the base frame side so as to assume a normal positional relationship.
