FIXING DEVICE OF SUPPORTING BODY IN WEAVING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a fixing device that precisely sets up the positioning of a fastening member fixing a supporting body to a slay of a weaving machine.SOLUTION: A fastening member comprises a T-shaped head portion 18 with parallelogram, a screw portion and a protrusion portion 20 in a shaft portion 17. A penetrating hole 26 comprising restricted surfaces 26A and 26B and a free space 25 is provided on a block 24 of the supporting body 15 of a sub nozzle 14. When the displacement S is created due to the variation of the fixing position by the tolerance between a T-groove 5 and the supporting body 15, a protrusion 20 is rotated within the free space 25 together with the shaft portion 17 and the T-shaped head portion 18 is rotated around a contacting portion between a lower short side 21 and a lower wall 7 of the T-groove 5 as a fulcrum, upon engaging the block 24 to a positioning groove 13 and rotating the shaft portion 17. At this time, since the shaft portion 17 and the protrusion 20 are rotatably and upwardly displaced, the T-shaped head portion 18 is rotated until the upper short side 21 is in contact with an upper wall 6. As the result, it can be configurated such that a center X2 of the shaft portion 17 is coincident with a center line X1 of a front opening portion 12 and a contact area between the T-shaped head portion 18 and the upper front wall and the lower front wall of the T-groove 5 is constant.
