Is extended, the guide rail 97 swings upward along the arc-shaped guide grooves 92a, 92a. As a result, one guide roller 23 engaged with the guide rail 97 is pressed upward, and the pivot shafts 20, 20 rotate in opposite directions together with the left and right roller support shafts 24, 24 interlocked via the interlocking gears 25, 25. Move. As a result, the front support arms 21 and 21 and the rear support arms 22 and 22 fixed to the pivots 20 and 20 expand outward.

  Subsequently, after the lift table 98 on which the subassembly SA is placed is raised to a predetermined height, the swinging cylinder 96 is contracted from the state shown in FIG. 19 to the state shown in FIG. 18 to form arcuate guide grooves 92a and 92a. Then, the guide rail 97 is swung downward. As a result, one guide roller 23 engaged with the guide rail 97 is pressed downward, and the pivot shafts 20, 20 rotate in opposite directions together with the left and right roller support shafts 24, 24 interlocked via the interlocking gears 25, 25. In order to move, the front support arms 21 and 21 and the rear support arms 22 and 22 fixed to the pivots 20 and 20 are closed inward.

  As a result, the lower support portions 26 and 26 of the front support arms 21 and 21 are engaged with both ends of the suspension rod 32 of the front conveyance jig Jf, and the rear conveyance arms 22 and 22 are suspended from the rear conveyance jig. Since the supporting members 80, 80 at the lower ends of the lower means 27, 27 are engaged with the engaged members 45, 45 of the rear conveying jig Jr, the lift table 98 is lowered to move the overhead assembly C to the overhead conveyor C. Transfer is completed.

  Next, a second embodiment of the present invention will be described with reference to FIGS.

  In the first embodiment described above, the rear transport jig Jr is supported only by the upper rail SRa of the seat rail unit SR of the subassembly SA. In the second embodiment, the rear transport jig Jr is supported by the seat rail of the subassembly SA. The unit SR is supported by the upper rail SRa and the lower rail SRb.

  That is, the first fulcrum members 48 and 48 are opposed to the front upper surface of the upper rail SRa, the second fulcrum members 56 and 56 are opposed to the lower surface of the lower rail SRb, and the third fulcrum members 60 and 60 are the upper rail SRa. Opposite the rear upper surface. Therefore, the second fulcrum members 56 and 56 supported by the upper collars 53 and 53 in the first embodiment are supported by the lower collars 54 and 54 in the second embodiment. In addition, the upper and lower positions of the third fulcrum members 60 and 60 are also adjusted so that the first fulcrum members 48 and 48 do not rise significantly from the upper surface of the upper rail SRa in a state where the rear conveyance jig Jr is mounted on the seat rail unit SR. The

  As described above, the upper and lower positions of the second fulcrum members 56 and 56 are adjusted in two stages, and the upper and lower positions of the third fulcrum members 60 and 60 are further finely adjusted. It can be made to correspond to the seat rail unit SR of the model.

  The embodiments of the present invention have been described above, but various design changes can be made without departing from the scope of the present invention.

  For example, in the embodiment, the positions at which the support members 80, 80 of the rear conveyance jig support means 27, 27 are engaged with the engaged members 45, 45 of the rear conveyance jig Jr are more than the third fulcrum members 60, 60. Although it arrange | positions back, the position should just be back rather than the 2nd fulcrum member 56,56. This is because if an upward load is applied to the rear of the second fulcrum members 56, 56, a moment in the direction of the arrow M 'in FIG.
