ABSTRACT:
A rotary rod bracing structure is composed of a main body and a circular inner pad, which is received in a recess of the main body. The bottom of the recess has a round hole. The circular inner pad is provided with a circular groove and an axial hole. The inner pad is received in the recess such that axial hole and the round hole are corresponding in location to receive the rotary rod. A plurality of balls is disposed in the circular groove such that the lubricating member is in contact with the inner wall of the recess for reducing the friction between the recess and the inner pad. The rotary rod is braced by the inner pad.
