る。A supporting bracket for an auxiliary suspension line is connected between the ends of two supporting brackets having a recess holding the auxiliary suspension line by a hinge so as to be freely opened and closed, and one of the supporting brackets is connected. It is fixed to the tip of the auxiliary arm, the other support metal piece is free, and is fixed to the support metal piece on the auxiliary arm fixed side via a bolt, thereby holding the auxiliary suspension line. For this reason, when an auxiliary suspension line is stretched, the auxiliary suspension line is inserted into the recess between the support bracket pieces and fastened with bolts and nuts. And there was a problem with its workability. In use, when the bolts and nuts are loosened and the bolts fall off, the space between the support brackets is inevitably opened. As a result, the auxiliary suspension wire comes off the support bracket and hangs down, which may cause an unexpected accident.

One of the support pieces is fixed to the auxiliary arm, and the other is a free end that is fixed by bolts. For this reason, the auxiliary suspension line stretched is merely temporarily inserted into the recess between the opened support bracket pieces, and is temporarily supported, so that the holding with the bolt is easily performed. Also, even if the bolts fall off during use and the space between the support brackets becomes open, the tensioned auxiliary suspension wire is locked to the support bracket on the fixed side of the arm, and it does not fall out unnecessarily. It prevents unexpected accidents and improves safety.
