Tilts of the two pillars are prevented by tilting in the same manner with each claw locked to the part as a fulcrum and abutting each other, and the locking of each claw to the hole is maintained and locked. Pulling out the body is prevented. Thereby, a clamp is maintained in the stable attachment state in the normal attachment state. In addition, when a force is applied in a direction in which the two pillars are aligned obliquely toward one of the directions in which the two pillars are arranged in the locking body portion, what is the direction in which the two pillars are obliquely extracted? increase tilted with respect to the position to one of the pillars other pillar on the other side, the wing while protruding direction is tilted from the radially outer side in the insertion direction side of the wing which projects from the one of the pillars pillars The claw is unlocked in a posture bent in the tip direction, and then the blade piece returns to a state of extending in the base direction of the column, and the locking body portion is pulled out from the hole portion. . Thereby, when removing a clamp, it becomes possible to remove easily.

Next, the second invention, the insertion of the engaging torque ramp to the first invention described above, between the tip portions of the two pillars of standoff region, the hole of the strut portion connecting the distal end portion to each other The thin-walled portion is formed so that the thin-walled portion is bent to prevent the tilting when the two columns tilt due to the thin-walled structure .
According to the second aspect of the present invention, since the tip portions of the two pillars of the support column portion are connected by the thin wall portion, the support column portion becomes an obstacle when the locking body portion is inserted into the hole portion. Without stopping, the locking body portion is smoothly inserted. Since the thin portion is configured to bend when the two columns tilt due to the thin structure, the thin portion does not hinder the tilting of the two columns provided in the column part .

The present invention can obtain the following effects by taking the above-described means.
First, according to the first invention, in a normal mounted state, the claws formed at each end of the two wings with respect to the hole formed in the plate-like components are engaged Since it is held so as not to come out of the locking body portion, it is possible to achieve a stable mounting state without rattling the clamp. Therefore, the holding state of the long attachment member such as the wire harness can be stabilized. Moreover, when removing a clamp, a clamp can be easily removed with the force which an operator pulls out, without using machines, such as a heavy machine. Therefore, it is possible to perform the removal work of the clamp quickly.
Next, according to the second aspect of the invention, the thin wall portion is provided so as to connect the tip portions of the two pillars of the column portion, so that the clamp can be quickly removed and locked. The body part can be inserted more smoothly into the hole part .

Further, the front surface side of the vehicle body panel 92 is elastically received by the base portion 22. Therefore, as shown in FIG. 11, the clamp 1 is in an attached state in which the vehicle body panel 92 is sandwiched between the base portion 22 of the locking body portion 20 and the locking claws 28. Thereby, the clamp 1 can be securely attached to the vehicle body panel 92.

Next, the case where pulling-out locked state or Ra引 the locking body portion 20 into the hole 94. As shown in FIG. 11 (A), when the force is withdrawn from the hole 94 to the securing body portion 20 in the vertical direction (pulling force P1) was pressurized Erare is Hidaritsume 28a and Migitsume 28b and the hole 9 4 and the pull-out in the vertical direction since the tightly engaged locks is prevented. For this reason, since the expanded state is firmly maintained between the left claw 28a and the right claw 28b, the engagement between the left claw 28a and the right claw 28b and the hole 94 becomes strong. Thereby, in a normal state, it can be set as the stable attachment state, without shaking a clamp.

On the other hand, as shown in FIG. 11 (B), the engaging member 20, in a case where the force P2 is pulled out to the oblique direction is applied thereto, the narrow Mel deformation Ri by the expanded state the work of crosslinking sites 36 it is allowed to pull in the state. Specifically, when a pulling force P2 is applied to the locking body portion 20 in an oblique direction, the left wing piece 26a moves leftward as viewed in FIG. 11B with the contact point between the left claw 28a and the hole 94 as a fulcrum. Get up. Then, since the first bridging portion 36a disposed on the left wing piece 26a pulls the lower part of the right wing piece 26b in the left direction as viewed in FIG. 11B, the right wing piece 26b is also left as viewed in FIG. 11B. It will stand up in the direction. Therefore, expansion state between the Hidaritsume 28a and Migitsume 28b deforms the distance to the narrow Me so that. As a result, the right wing piece 26 b can pass through the hole 94, and the left wing piece 26 a also slips from the hole 94 as the right wing piece 26 a passes through the hole 94. That is, the clamp can be easily removed by the interaction between the left wing piece 26a and the right wing piece 26b. In this way, the locking body portion 20 is pulled out from the hole portion 94 formed in the vehicle body panel 92 by the pullable means. The second bridge member 36b is not be affecting since no or essentially dynamic when the rising operation of the right wing pieces 26b with the rising operation of the right wing piece 26b.
The pullable means added to the locking means in the present embodiment prevents the vertical pulling out by maintaining the expanded state at the lower end of the locking piece part, and this expanded state is achieved by the action of the bridging part. Pulling in an oblique direction is allowed by making the deformation state narrow.
According to the clamp according to the present embodiment as described above, it is possible to easily removed without the use of machine such as a clamp 1 vehicle body panel 92 or RaShigeru machine. Therefore, it becomes possible to perform the removal operation of the clamp 1 quickly.
