状態になっている。First, after the guide rail 41 is centered in the longitudinal direction, the height direction and the width direction, it is attached to the truss 40 with bolts and nuts. Next, the turn track 32 is temporarily removed from the base 31, and the shaft 22 (driven sprocket 21
And the roller 23 is already attached)
Is mounted on the guide rail 41, and then the turn track 32 is attached to the base 31 again. At this time,
The groove 24 of the shaft 22 is engaged with the notch 31a of the base 31.

Attach to 40. Then, the rod 26 penetrates the truss 40 and is screwed into the tap hole 25 of the shaft 22 to tighten the nut 26 a, and the spring 28 is interposed between the spring seat 27 and the truss 40.
(Biasing device) is inserted and shipped.
