Therefore, when the binding band 16 has the same thickness as that of the binding band 15, the depth of the engagement recesses 16a and 16b is shallower than the engagement recesses 15a and 16a by the thickness of the partition wall 16d.

Below, the usage example of the binding member which uses the stopper 11 and the binding band 15 is demonstrated.
As shown in FIG. 8, the operator bundles a plurality of electric wires 22 of the member 21 to be bundled together by a bundling band 15 cut to an appropriate length, and bundles one end 15d as shown in FIG. The stopper 11 is inserted in the direction of arrow A from the opening end 11 b of the stopper 11, and the engaging recess 15 b on the inner surface of the binding band 15 is engaged with the locking claw 13 b of the tongue piece 13. At this time, it is preferable to extend the terminal 15d from the opening end 11a of the stopper 11 to an appropriate length. Thereby, the one side terminal 15d of the binding band 15 is fixed to the tongue piece 13 of the stopper 11, and the removal is prevented.

  Next, the operator inserts the terminal 15e on the other side of the binding band 15 in the direction of arrow B from the opening end 11a of the stopper 11 as shown in FIG. 9, pulls it out from the opening end 11b, and moves the arrow 15 as shown in FIG. Pulling in the B direction, the electric wire 22 is tightened, and the engaging recesses 15a on the outer surface are engaged with the respective locking claws 12b of the tongue piece 12. At this time, the binding band 15 is twice as thick as the other terminal 15e overlaps the one terminal 15d, and the tongue piece 12 is bent outward from the base portion 12a due to elasticity, so that the binding band 15 can be inserted. It becomes easy. When the fastening of the binding band 15 is stopped, the tongue piece 12 is restored to its original state by elasticity, and the locking claw 12b is engaged with the engaging recess 15a facing the binding band 15. The one side terminal 15d of the binding band 15 is extended from the opening end 11a side of the stopper 11, and the other side terminal 15e side inserted from the opening end 11a side is overlapped on the one side terminal 15d side to increase the thickness. Thus, the engaging claw 12b of the tongue piece 12 can be deeply engaged with the engaging recess 15a on the other terminal 15e side, and it is prevented from coming off. Thereby, the binding band 15 is firmly fixed to the stopper 11 in a state in which the plurality of electric wires 22 are tightened, and is prevented from coming off. After the binding, the terminal 15e of the binding band 15 protruding from the opening end 11b of the stopper 11 is cut to an appropriate length.

  When the binding band 15 is tightened, as shown in FIGS. 9 and 10, the tightening direction of the binding band 15 is the same as the direction in which the binding band 15 is inserted into the stopper 11, and the binding band 21 has a force to bind. It can be tightened, the efficiency of force when binding is good, and it is easy to tighten. Further, the stopper 11 and the binding band 15 have lubricity, and the widths of the locking claws 12b and 13b are approximately half the width of the engagement recesses 15a and 15b, so The sliding resistance between the claws 12b and 13b and the binding band 15 is reduced and workability is improved. Further, as shown in FIG. 3, the stopper 11 has the tongue pieces 12 and 13 and the locking claws 12 b and 13 b that are formed point-symmetrically, so that it is easy to use and the workability is improved. Thereby, the wire harness etc. of a motor vehicle can be bundled easily.

  When a specific electric wire 21 is removed from a plurality of electric wires 22 bound by the stopper 11 and the binding band 15 or when the binding by the binding band 15 is released, as shown by a two-dot chain line in FIG. For example, the tip of a thin screwdriver 23 is inserted into the gap between the tip inner edge 12 c of the tongue piece 12 and the binding belt 15. At this time, the tip of the tongue piece 12 is chamfered to form a curved surface, so that the driver 23 can be easily inserted. Next, the tongue piece 12 is bent outward by the driver 23, the engagement claw 12b is separated from the engagement recess 15a to release the engagement, and the binding belt 15 is pulled in the direction of arrow C indicated by the dotted line. Thereby, the terminal 15e side of the binding band 15 can be easily removed from the stopper 11, and workability can be improved. Further, the removed binding band 15 can be used again.

  As shown in FIG. 9, when the binding band 15 of the type in which the engagement recesses 15a and 15b are alternately formed on both sides as the binding band is used, the engagement recesses 15a and 15b can be deepened, and the tongue of the stopper 11 can be formed. The locking claws 12b and 13b of the pieces 12 and 13 can be deeply engaged, and the height of the stopper 11 can be lowered, which is preferable in reducing the size of the stopper 11. When the binding band 16 shown in FIG. 7 is used, the pitch of the engaging recesses 16a and 16b is half the pitch of the locking claws 12b and 13b. Is easy to adjust.
