It is configured to face the chamfered portion 8b.

  In the present embodiment, the pressing portion 32 is formed in a rod shape extending in the axial direction of the operation portion 30 (in the direction of the axial center 9 of the binding tool 1), and both side portions in the width direction of the operation portion 30 ( It is provided on the left and right sides). Each of the left and right pressing portions 32 is disposed on the outer side in the width direction of the connecting portion 10 so as to be spaced apart from the connecting portion 10 by a predetermined distance. The pressing portion 32 is connected to the insertion support portion 7 of the holding portion 2 at one end portion (upper end portion).

  The linkage portion 33 is formed in a bent shape so as to protrude downward, and is provided on both sides (left and right sides) of the operation portion 30 in the width direction. Each of the left and right linkage parts 33 is disposed between the corresponding other end part (lower end part) of the pressing part 32 and the upper end part of the interlocking part 25 of the pushing part 20. Each linkage portion 33 is connected to the lower end portion of the corresponding pressing portion 32 at one end portion.

  Each linkage portion 33 is also connected to the upper end portion of the corresponding interlocking portion 25 in the push-in portion 20 at the other end portion. Thus, the left and right side portions of the upper portion of the fixing portion 3 are surrounded by the pressing portion 32 and the linkage portion 33 of the operation portion 30, the connecting portion 10, the insertion support portion 7 of the holding portion 2, and the like. As a result, a gap 35 is formed.

  As a result, in the operation unit 30, the pressing portions 32 are bent by elastic deformation by pressing the pressing portions 32 in the direction of reducing the width of the pressing portion 20, that is, inward in the width direction (axial center side). However, the upper end portion side of each interlocking portion 25 of the push-in portion 20 is pressed inward in the width direction (axial center side) via each linkage portion 33, and each interlocking portion 25 is elastic with the extending portion 27 as a fulcrum. It can be deformed. On the other hand, if this pressing is released, the operation portion 30 can be deformed to its original shape by elastic restoration of the push-in portion main body 21 and / or elastic restoration of the respective pressing portions 32.

  Here, the linkage part 33 includes a protruding end part 33a positioned below a corresponding connecting part to the interlocking part 25, and a downward inclined shape from the upper end part of the interlocking part 25 toward the protruding end part 33a. And an opposing portion 33c extending upwardly from the protruding end portion 33a toward the lower end portion of the pressing portion 32.

  The facing portion 33c has a shape corresponding to the chamfered portion 8b, specifically, a shape having an inclined facing surface along the chamfered portion 8b on the outer peripheral portion. And the said opposing part 33c opposes the said chamfering part 8b in the said opposing surface at the time of engagement with the protrusion part 22 of the said pushing part 20, and the inner wall part of the said screw hole 8, and with respect to this chamfering part 8b It is provided so as to have a predetermined gap or contact.

  With the configuration as described above, when the pushing portion 20 is pushed into the screw hole 8, the projecting portion 22 is elastically deformed along with the pushing operation, and simultaneously with the pushing portion main body 21 that is elastically deformed, the screw When entering into the hole 8 and stopping the pushing operation, as shown in FIG. 4, the protruding portion 22 can be elastically restored and engaged with the inner wall portion of the screw hole 8 as in the pushing portion main body 21. It becomes possible. That is, it becomes possible to hold the pushing portion 20 in a state in which the pushing portion 20 is prevented from coming off in the screw hole 8. Therefore, the binding tool 1 (the fixing portion 3) can be easily fixed to the fixing member 5.

  Moreover, after the binding tool 1 (the fixing portion 3) is fixed to the fixing member 5, the operation portion 30 (the pressing portions 32) is moved inward in the width direction (the direction in which the width of the pressing portion 20 is reduced) (see FIG. In the direction of reducing the width of the pressing portion 20 by elastic deformation in conjunction with this deformation, as shown in FIG. It becomes possible to bend, and it becomes possible to cancel | release engagement with the protrusion part 22 of the said pushing part 20, and the inner wall part of the said screw hole 8. FIG. Therefore, the pushing portion 20 can be pulled out from the screw hole 8 without breaking. Therefore, the said binding tool 1 (the said fixing | fixed part 3) can be removed from the said fixing member 5 using the said operation part 30, and it can be reused after removal.

  As a result, for example, when carrying out maintenance work or the like of automobiles and equipment including the fixing member 5, the binding tool 1 in a state in which holding objects such as wiring, piping, and tubes are bound from the fixing member 5. After detaching and temporarily moving, the binding tool 1 can be returned to the original position and fixed to the fixing member 5. Therefore, it is not necessary to prepare a new binding tool (binding band) every time maintenance work is performed, and it is not necessary to perform the binding release work and the binding work associated with the replacement of the binding tool at such time.

  In addition, when the fixing member 5 vibrates at the time of fixing the binding tool 1 to the fixing member 5, the binding tool 1 affected by the vibration tends to be largely inclined with respect to the fixing member 5. In addition, the link portion 33 (the facing portion 33c) can be brought into contact with the chamfered portion 8b to regulate the degree of inclination thereof. Accordingly, the protruding portion 22 of the pushing portion 20 that engages with the inner wall portion of the screw hole 8 by the inclination of the binding tool 1 releases the engagement (the pushing portion 20 is detached from the screw hole 8). Can be prevented from being damaged or excessively deformed. As a result, it is possible to make it difficult for the binding tool 1 to be detached from the fixing member 5.

  Moreover, in this embodiment, as shown in FIG. 2, FIG. 4, the said binding tool 1 is provided with the reinforcement part 38. As shown in FIG. The reinforcing portion 38 is for increasing the deformation strength of the operation portion 30 inward in the width direction, and extends in the width direction between the pushing portion 20 and / or the operation portion 30 and the connecting portion 10.

The reinforcing portion 38 is connected to a connecting portion between the linkage portion 33 (the extending portion 33b) of the operation portion 30 and the interlocking portion 25 of the pushing portion 20 at one end portion in the longitudinal direction, and at the other end portion in the longitudinal direction. It is connected to the connecting part 10.

  With such a configuration, the pushing portion 20 and the operation portion 30 are not easily deformed inward in the width direction, and vibration or the like is generated when the protruding portion 22 of the pushing portion 20 and the inner wall portion of the screw hole 8 are engaged. It is possible to prevent the pushing portion 20 from being detached from the screw hole 8 due to unintentional deformation of the pushing portion 20 and the operation portion 30 due to, that is, the binding tool 1 can be easily removed from the fixing member 5. It becomes possible to do. In addition, it is preferable to set the said deformation | transformation intensity | strength to the grade which can operate the said operation part 30 not by the operator's manual operation but by operation using a tool.

  Moreover, in this embodiment, the said protrusion part 22 is the said connection part rather than the inner peripheral side edge part (connection side edge part with the said pushing part main body 21) 22b in the outer peripheral side edge part (the said protrusion edge part) 22a. It is located closer to 10. In the present embodiment, as shown in FIG. 4, the projecting portion 22 has the pushing portion main body 21 so that an angle formed by the projecting portion 22 and the axis of the pushing portion main body 21 is an acute angle in a sectional view. It is formed in the inclination shape extended toward an outer side upward.

  With such a configuration, when the pushing portion 20 is pushed into the screw hole 8 from the opening 8a, the projecting end portion 22a of the projecting portion 22 approaches the pushing portion main body 21, that is, the pushing portion 20 The protrusion 22 is easily elastically deformed so as to reduce the width. Therefore, the pushing portion 20 can be easily pushed into the screw hole 8.

  In addition, after the pushing portion 20 is pushed into the screw hole 8, the projecting portion 22 is engaged with the inner wall portion of the screw hole 8 by elastic restoration, and the projecting portion 22 is in the pushing portion main body 21. It becomes difficult to elastically deform toward the lower side. That is, the engagement between the protruding portion 22 and the inner wall portion of the screw hole 8 is difficult to be released. Therefore, it is possible to prevent the pulling strength of the pushing portion 20 (the fixing portion 3) from being lowered with respect to the fixing member 5.

  Moreover, in this embodiment, as shown in FIG. 1, FIG. 3, etc., the said fixing | fixed part 3 is provided with the collar part 40. As shown in FIG. The flange portion 40 is configured to be elastically deformed and press-contacted to the outer surface of the fixing member 5 when the pushing portion 20 is pushed into the screw hole 8.

A plurality are arranged so as to be arranged at a predetermined interval from each other. Each of the second projecting portions 42 has a projecting end portion 42a positioned concentrically with the projecting end portion 41a of the first projecting portion 41, and has a predetermined angular range (180) around the axis of the push-in portion main body 21. Less than degree).

  Further, the second projecting portion 42 is disposed at a position shifted in the axial direction of the push-in portion main body 21 with respect to the first projecting portion 41. In the present embodiment, the same number of the second protrusions 42 as the first protrusions 41 are provided so as to correspond one-to-one. Then, with respect to the axial direction of the push-in portion main body 21, the second projecting portion 42 (its projecting end portion 42a) is disposed above the corresponding first projecting portion 41 (its projecting end portion 41a) by a predetermined width.
