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. ## Claims ### Claim 1 A method for the assembly of a sun roof for an automotive vehicle, wherein the sunroof comprises (1) a pair of left-hand and right-hand roof opening sections each at a front portion of a roof panel, wherein the openings each form an open-side transversing the roof panel, and wherein the openings each form a closed-side at a front side, a rear side, and a longitudinally inner side;

and connecting a right-hand outer side portion of said front header to a right-hand outer side portion of said rear roof panel section with a right-hand aligning jig. ### Claim 3 (depends on 1) A method for the assembly of a sun roof as claimed in claim 1, wherein said connecting step comprises: connecting a left-hand outer side portion of said front base frame section to a left-hand outer side portion of said front base frame section with a left-hand aligning jig; and connecting a right-hand outer side portion of said front base frame section to a right-hand outer side portion of said rear base frame section with a right-hand aligning jig. ### Claim 4 (depends on 2) A method for the assembly of a sun roof as claimed in claim 2, wherein said base frame further comprises (d) a left-hand guide section extending rearward from the left-hand outer side portion and a right-hand guide section extending rearward from the right-hand outer side portion. ### Claim 5 (depends on 4) A method for the assembly of a sun roof as claimed in claim 4, wherein said connecting steps comprise: connecting one sheet of an aligning jig in the form of a plate to at least (i) said left-hand and right-hand outer side portions of the front base frame section, (ii) said rear base frame section, and (iii) said left-hand and right-hand end portions of said guide sections. ### Claim 6 (depends on 5) A method for the assembly of a sun roof as claimed in claim 5, wherein said plate form aligning jig is larger than all peripheral edge portions of said base frame and said plate form aligning jig is connected to said base frame. ### Claim 7 (depends on 2) A method for the assembly of a sun roof as claimed in claim 2, wherein said at least one aligning jig in step is said movable roof member. ### Claim 8 (depends on 2, 3, 4, 5, 6, 7) A method for the assembly of a sun roof as claimed in any one of claims 2 to 7, wherein said at least one aligning jig is connected to said body or said base frame with a detachable fixing member. ### Claim 9 (depends on 8) A method for the assembly of a run roof as claimed in claim 8, wherein said fixing member comprises a bolt and a nut. ### Claim 10 A method for the assembly of a sun roof for an automotive vehicle, wherein the sunroof comprises (1) a pair of left-hand and right-hand roof opening sections each at a front portion of a roof panel, wherein the openings each form an open-side transversing the roof panel, and wherein the openings each form a closed-side at a front side, a rear side, and a longitudinally inner side; (2) a movable roof member large enough to substantially cover the pair of the left-hand and right-hand roof opening sections, wherein the movable roof ember moves longitudinally through a base frame fixed to a body of the vehicle, and wherein the movable roof member simultaneously opens and closes the left-hand and right-hand roof opening sections; and (3) said base frame comprises (a) a front base frame section extending transversely over substantially the entire length of and along a front header constituting a front edge portion of the roof opening sections; (b) a rear base frame section extending transversely over substantially the entire length of and along a front edge portion of a rear roof panel section; and (c) a middle base frame section extending longitudinally and connecting a middle portion of said front base frame section and a middle portion of the rear base frame section; wherein the method for assembly comprises the steps of: forming a first alignment member at transversely outer side portions of said front header and at transversely outer side portions of said front edge portion of the rear roof panel section;
