An opening is formed in between, and the weft thread is inserted into this opening. In the above case, lubricant is supplied between the inner circumferential surface of the shaft hole 40' of the bearing body 34 and the outer shaft 42 of the mounting shaft 35 from within the storage recess 48 of the bearing body 34. The inner peripheral surface of the shaft hole 40 and the outer ring 42 of the mounting shaft 35 can be well lubricated, and the storage recess 48 and the inner peripheral surface of the shaft hole 40 are communicated with each other by the pores 50, so that there is no oil from the storage recess 48. The lubricant is applied to the inner peripheral surface of the shaft hole 40 of the bearing body 34 and the mounting shaft 35.
As a result, a small amount of lubricant is supplied between the outer ring 42 of the bearing body 34 and the outer ring 42 of the mounting shaft 35 for a long period of time.

In addition, since the lubricant holder 38 that soaks lubricant is provided in the storage recess 48, even if the bearing body 34 moves due to the swinging of the setting lever 6, the lubricant is not kept in the storage recess 48. The lubricant can be stored stably over a long period of time, and the inner circumferential surface of the shaft hole 40 of the bearing body 34 and the outer shaft 42 of the mounting shaft 35 can be satisfactorily lubricated for a long period of time. Further, a lubricant supply hose 56 is inserted into the hose guide cylinder parts 54 and 55 of the cover 37 inserted into the storage recess 48, so that the lubricant supply hose 56 is communicated with the inside of the cover part 52 of the cover 37. Therefore, when the lubricant soaked into the lubricant holder 38 runs out, the lubricant can be easily supplied to the lubricant holder 3 days later through the lubricant supply hose 56.

If the wire 7 is damaged, loosen the fixing bolt 32, remove it from the female thread 19 of the receiver 15, and remove it from the locking body 26.
is rotated as shown by the imaginary line in FIG. The interval is made larger than the vertical dimension of the flange 24 of the connecting body 22, and the connecting body 22 is pulled out from between the adjacent receivers 15.
