  According to the invention shown in claim 4, the upper connecting plate and the lower connecting plate made of two plate-like members are connected to each of the left engaging portion and the right engaging portion in a state where one end is superposed, By engaging and connecting each suspension support rod to the other end of the connection plate / lower connection plate, multiple-point suspension support in a state of exhibiting anti-vibration (anti-vibration) properties can be obtained. Moreover, the upper connecting plate and the lower connecting plate can change the overlapping angle of the two sheets when one end is overlapped according to the angle of the diagonally suspended support of the suspended support rod, so that in a more stable state Multiple point suspension support is obtained.

  According to the fifth aspect of the present invention, since the upper connecting plate and the lower connecting plate are configured using plate members having exactly the same structure, either the upper connection plate or the lower connection plate can be used without paying attention to the vertical relationship of layering these two sheets. Functions as a connecting plate member. In addition, when manufacturing it, a single type of manufacturing facility such as a mold is sufficient, so that production efficiency is high, manufacturing costs can be reduced, and only one type of plate member is manufactured, so inventory management, order receipt management, Delivery management is easy.
