The pressure receiving portion 12 formed in this manner is connected and held by a pair of joining pieces 17 having the same length. One end of the pair of joining pieces 17 is connected to the pair of clamping pieces 3,
A thin-walled hinge 18 is located at a corresponding position on the opposite surface of 6.
The other end is connected to the pressure receiving part 12.
are connected via thin hinges 19 to symmetrical positions on the back side of the receiving board 13. The pair of joint pieces 1 that connect and hold the pressure receiving part 12 in this way
A kind of parallel link is formed by the joint parts 3a and 6a of the hinge 18 from the hinge part 2 of the clamping pieces 3 and 6 that form a pair with 7, and when the locking piece 3 and the gripping part 7 are engaged, pressure is received. The portion 12 is located on the opening side, that is, the gripping portion 7, approximately along the center line of the expansion angle of the gripping pieces 3, 6.
It is formed to move forward to a predetermined position on the side.

Next, the operation and effects of this embodiment configured as described above will be explained.

Now, the fastener 1 of this example is provided with a pair of clamping pieces 3 and 6 in a diverging shape via a hinge part 2, and the distal ends of the clamping pieces 3 and 6 are opposed and engageable with each other. A stopper piece 4 and a gripping part 7 are provided, and a pressure receiving part that can be elastically deformed into an arc shape is provided on the free end side of a pair of connecting pieces 17 connected via a hinge 18 from the pair of clamping pieces 3 and 6, respectively. 12 is provided, and the locking piece 4
When the grip part 7 is engaged with the wire harness W, the pressure receiving part 12 is moved forward in the direction of the locking piece 4 via the joint piece 17, and the wire harness W is pushed and fixed by the pair of joint pieces 17. This is what I did. Therefore, when disposing the wire harness W1 having the outer diameter D1, the wire harness W1 is first inserted between the pair of clamping pieces 3 and 6, and then the locking piece 4 and the gripping part 7 are engaged with each other. When the pressure receiving part 12 is fitted together, the pressure receiving part 12 is moved forward to a predetermined position, and the pair of joint pieces 17 acts like a tensioner, so that the contact piece 15 of the pressure receiving part 12 comes into contact with the outer periphery of the wire harness W1, and The wire harness W1 is pressed against the gripping part 7, and the corresponding contact piece 15 is elastically deformed along the outer periphery of the wire harness W1, and the entire shape of the pressure receiving part 12 is elastically deformed into an arc shape as shown in the figure. The wire harness W1 is firmly and elastically held between the pressure receiving part 12 and the gripping part 7 due to the multiple force of 15 and the tensile force of the pair of joining pieces 17.

Next, when the wire harness W2 with the outer diameter D2, which is slightly larger than the outer diameter D1, is attached using the same fastener 1 in the same manner as above, the contact piece 15 of the pressure receiving part 12 is further elastically deformed, and the receiving surface of the receiving board 13 is 14, and the pair of joint pieces 17 acts as tension to tighten the wire harness W2.
