も充分に抗するものである。 Now, the fastener 3 of this example is made of synthetic resin or the like, in which the locking leg 5 is inserted into the mounting hole 2 penetrated through the steel plate body 1 and is elastically engaged to arrange the wire harness W, etc. The locking leg 5 has a central shaft 6 that can be inserted into the mounting hole 2 from the lower surface of the mounting board 4 of the wire harness W, and a central shaft 6 that can be inserted into the mounting hole 2 is vertically disposed at the tip of the central shaft 6. A locking piece 8 having a locking surface 9 and elastically deformable is provided, and a first joint piece 15 and a second joint piece 15 are provided on both sides of the central shaft 6 symmetrically and diagonally upward at a predetermined angle. A piece 16 is provided on the distal end sides of the joint pieces 15 and 16 at a predetermined distance from the central axis 6 and parallel to the locking surface 9 of the locking piece 8 and the lower surface of the mounting board 4. The leg pieces 10 that are joined to the two leg pieces 10 are connected symmetrically, and the outer surfaces of both leg pieces 10 are provided with a second locking claw 12, a third locking claw 13, and a fourth locking claw diagonally upward at a predetermined interval. 14 are formed to protrude symmetrically, and each locking claw 1
Joint pieces 15, 16 and leg piece 1 for 2, 13, 14
0 and the central axis 6 form one or more pairs of substantially parallelogram-shaped receiving parts. Therefore, in order to install the wire harness W using this fastener 3, the wire harness W is first wound and fixed around the mounting board 4 using adhesive vinyl tape or the like. Thereafter, when the tip of the locking leg 5 is brought into contact with the mounting hole 2 and pressed, the left and right locking pieces 8, 8 are guided by the edge of the mounting hole 2 and are elastically displaced toward the central shaft 6.

If the plate thickness is between t2 or t3 between the interval T2 and the interval T3 between the third locking claws, further pressure is applied to the second plate corresponding to the respective plate thickness.
By engaging the locking pawl 12 or the third locking piece 13 with the lower surface of each mounting hole 2, the locking can be achieved without wobbling, and the locking piece 8 and the first The reaction force of the joining piece 15 can sufficiently resist the movement and prevent it from coming off. Next, in the case of a thin plate thickness t4 corresponding to the interval T4 of the fourth locking pawl 14, by further pressing and locking the lower surface of the mounting hole 2, the mounting board 4 and the fourth locking pawl 14 can be In this case, the connecting piece 11 is attached to the mounting hole 2 in a pinched manner.
It can be easily attached close to the edge of the In addition, even if an external force is applied in the pulling direction in this state, the first joint piece 15, the second joint piece 16, the leg piece 10, and the central shaft 6 form a substantially parallelogram-shaped support against the fourth locking pawl 14. It is possible to sufficiently resist external force and prevent it from coming off.
