PROBLEM TO BE SOLVED: To provide a fixing member that is prevented from being attached to an attachment mating side in an incomplete state.SOLUTION: The fixing member 1 is inserted from an outer wall side 62 of an attachment mating side 61 into a through hole 64 penetrating through an inner wall side 63 and is fixed to the attachment mating side 61, and has: a tensile part 11 which is inserted into the through hole 64 and applies tensile force to the inner wall side 63; an elastic deformation part 21 which is elastically deformed to the inside of the through hole 64 as the tensile part 11 is pulled to the inner wall side 63 and is moved from the outer wall side 62 to the inner wall side 63; an abutment part 31 which is in abutment with the outer wall side 62 of the attachment mating side 61 as the elastic deformation part 21 is moved to the inner wall side 63 and is elastically restored; and a fracture part 41 formed in the tensile part 11 or the elastic deformation part 21. The fracture part 41 is fractured by pulling the tensile part 11 to the inner wall side 63 by force larger than that produced when the elastic deformation part 21 is elastically deformed inside the through hole 64 while the abutment part 31 is brought into abutment with the outer wall side 62.

Description

  The present invention relates to a fixing member that is inserted into a through hole on an attachment counterpart side and fixed to the attachment counterpart side.

  For example, a clip for a wire harness described in, for example, Japanese Patent Application Laid-Open No. 2003-125525 (Patent Document 1) has been proposed as a fixing member that is fixed to an attachment counterpart.

  This wire harness clip attaches the wire harness to the engine side by inserting an attachment shaft portion integrally connected to a holding portion for holding the wire harness into an attachment hole formed on the engine side of the vehicle.

  The mounting shaft portion includes an engaging circumferential groove portion that fits into the mounting hole, a tapered guide portion that is formed adjacent to the edge of the engaging circumferential groove portion and is similar to the mounting hole and larger than the mounting hole, And a knob shaft extending from the tip of the tapered guide portion.

  Then, when the knob shaft is inserted into the mounting hole and pulled, the tapered guide section that is larger than the mounting hole moves inside the mounting hole while bending, and when it passes through the mounting hole, it returns to its original shape, and the engagement circumferential groove section is mounted. The wire harness is held on the engine side by engaging with the hole.

JP 2003-125525 A

  By the way, in the conventional wire harness clip described above, the tapered guide portion returns to its original shape when passing through the mounting hole, and the engaging circumferential groove portion is engaged with the mounting hole, so that the knob shaft is picked. The vibration transmitted when the tapered guide portion returns to the original shape is transmitted to the hand.

  For this reason, the engagement state between the engagement circumferential groove portion and the mounting hole is not visually confirmed, and it may be confirmed that the tapered guide portion is engaged with a click feeling due to vibration when returning to the original shape, There is a case where it is erroneously recognized that there is a click feeling and the engagement between the engagement circumferential groove and the mounting hole is not completed.

  Therefore, the present invention has been made to solve such a conventional problem, and the object of the present invention is to fix the fixing member to prevent the fixing member from being attached in an incomplete state to the mounting counterpart. It is to provide a member.

  In order to achieve the above object, the fixing member of the present invention described in claim 1 of the present invention is a fixing member that is fixed to the mounting partner side through a through-hole penetrating from the outer wall side of the mounting partner side to the inner wall side. A tension portion that is inserted into the through-hole and applies a pulling force to the inner wall side; and by pulling the tension portion toward the inner wall side, the inner portion is elastically deformed to the inside of the through-hole and is then An elastic deformation portion that moves to the inner wall side, an elastic contact portion that contacts the outer wall side of the mounting counterpart when the elastic deformation portion moves toward the inner wall side and is elastically restored, and the tension portion or the elastic deformation portion. A breakage portion, and the breakage portion is pulled with a greater force than when the elastic deformation portion is elastically deformed inside the through hole in a state where the contact portion is in contact with the outer wall side. By pulling the part to the inner wall side, Characterized by broken while maintaining the engagement of the elastic deformation portion to the inner wall of the circumference.

  A fixing member according to a second aspect of the present invention is the fixing member according to the first aspect, wherein a diameter of the fracture portion is smaller than a diameter of the tension portion.

  The fixing member according to a third aspect of the present invention is the fixing member according to the first or second aspect, wherein the fracture portion is provided between the tension portion and the elastic deformation portion. It is characterized by that.

  According to the fixing member of the present invention described in claim 1, the fracture portion has a greater force than when the elastic deformation portion is elastically deformed inside the through hole in a state where the contact portion is in contact with the outer wall side. It breaks by pulling the tension part to the inner wall side. For this reason, it can confirm that the fracture | rupture part fracture | ruptured that the elastically deformed elastic deformation | transformation part elastically restored and the fixing member was attached to the attachment other party side in the perfect state (normal fitting state).

  Moreover, it can confirm that the fixing member was attached to the attachment other party side in the perfect state (normal fitting state) because the fracture | rupture part fractured | ruptured. For this reason, although the elastically deforming portion is not elastically restored, the fixing member is attached in an incomplete state (half-fitted state) to the attachment counterpart side by stopping the pulling of the pulling portion. There is nothing.

  Therefore, it is possible to provide a fixing member that prevents the fixing member from being attached in an incomplete state with respect to the attachment counterpart.

  According to the fixing member of the present invention described in claim 2, since the diameter of the fracture portion is formed smaller than the diameter of the tension portion and the elastic deformation portion, the elastic deformation portion can be arranged inside the through hole with a simple configuration. The rupture portion can be broken by pulling the tension portion toward the inner wall with a greater force than when it is elastically deformed.

  According to the fixing member of the present invention described in claim 3, since the fracture portion is provided between the tension portion and the elastic deformation portion, the fixing member is attached when the vicinity of the contact portion is fractured. It can prevent coming off from the counterpart through-hole.

  Hereinafter, a fixing member according to an embodiment of the present invention will be described with reference to the drawings. First, the fixing member which is a premise of the fixing member according to the embodiment of the present invention will be described. FIG. 1 is a cross-sectional view showing a fixing member as a premise of a fixing member according to an embodiment of the present invention. FIG. 2 is a cross-sectional view showing a case where a fixing member, which is a premise of the fixing member according to the embodiment of the present invention, is attached to the attachment counterpart side.

  The fixing member which is a premise of the fixing member according to the embodiment of the present invention is a fixing member which is inserted into a through hole penetrating from the outer wall side on the attachment counterpart side to the inner wall side and fixed to the attachment counterpart side.

  As shown in FIGS. 1 and 2, the fixing member 1 includes a tension portion 11 that applies a pulling force to the fixing member 1 toward the inner wall side 63 (see arrow X in FIG. 1) of the attachment counterpart 61, and the attachment counterpart 61. The elastic deformation portion 21 is elastically deformed inside the through hole 64.

  The fixing member 1 includes a contact portion 31 that contacts the outer wall 62 of the attachment counterpart 61 and an insertion portion 51 that is inserted into the through hole 64 when the fixing member 1 is attached to the attachment counterpart 61. ing.

  The pulling portion 11 is a pulling operation that is a force point for pulling the distal end portion 12 inserted into the through hole 64 on the attachment counterpart side 61 and the inner wall side 63 of the attachment counterpart side 61 (see arrow X in FIG. 1). Part 13.

  The elastic deformation portion 21 protrudes from the outer periphery of the shaft portion 22 connected to the pulling operation portion 13 and the shaft portion 22 and elastically deforms inside the through hole 64 when passing through the through hole 64 on the attachment counterpart side 61. Part 23.

  The protrusion 23 has a substantially triangular shape when viewed from the side. As shown in FIG. 2, the protrusion 23 is elastically deformed when the elastic deformation portion 21 moves to the inner wall side 63 of the attachment counterpart 61. Is restored elastically, and the fixing member 1 is prevented from returning to the outer wall side 62.

  As shown in FIGS. 1 and 2, when the elastically deforming portion 21 moves from the outer wall side 62 of the mounting counterpart side 61 to the inner wall side 63 (see arrow X in FIG. 1), the contact portion 31 contacts the outer wall side 62. It has a contact surface 32 in contact therewith.

  As shown in FIGS. 1 and 2, in the fixing member 1 configured as described above, first, the distal end portion 12 is inserted from the outer wall side 62 of the mounting counterpart side 61, and the tension operation portion 13 is inserted into the inner wall side 63 (see FIG. The pulling portion 11 is inserted into the through hole 64 by pulling.

  When the tension portion 11 is inserted into the through hole 64, the shaft portion 22 is inserted into the through hole 64 by further pulling the tension operation portion 13 on the inner wall side 63 (see arrow X in FIG. 1).

  After the shaft portion 22 is inserted into the through hole 64, when the pulling operation portion 13 is further pulled toward the inner wall side 63 (see arrow X in FIG. 2), the protruding portion 23 is located inside the through hole 64 as shown in FIG. 2. It moves elastically from the outer wall side 62 to the inner wall side 63 (see arrows Y and Z in FIG. 1).

  When the pulling operation portion 13 is pulled toward the inner wall side 63 (see arrow X in FIG. 1) in a state where the protrusion 23 is elastically deformed inside the through hole 64, the elastic deformation portion 21 is moved to the inner wall side as shown in FIG. It moves to 63 and penetrates the through-hole 64, and the elastically deformed protrusion 23 is elastically restored.

  As shown in FIG. 2, when the protrusion 23 is elastically restored, the contact surface 32 contacts the outer wall side 62. When the contact surface 32 comes into contact with the outer wall side 62, the fixing member 1 is attached and fixed to the attachment counterpart side 61.

  By the way, in the fixing member 1 described above, when the elastically deformed elastic deformation portion 21 moves to the inner wall side 63 and elastically restores through the through hole 64, vibration (click feeling) is generated in the hand pulling the pulling operation portion 13. It is transmitted.

  In this way, since a click feeling is felt in the hand, it is not visually confirmed that the fixing member 1 is attached to the attachment counterpart side 61 in a complete state (normally fitted state), and the elastic deformation portion 21 is elastic. It may be confirmed by a click feeling due to vibration when restored.

  For this reason, it is mistakenly recognized that there is a click feeling, and the pulling operation unit 13 is stopped from pulling even though the protrusion 23 is not elastically restored. There is a risk of being attached in a complete state (half-fitted state).

  Therefore, the fixing member according to the embodiment of the present invention is configured so that the tension portion is placed on the inner wall side with a greater force than when the elastic deformation portion is elastically deformed inside the through hole in a state where the contact portion is in contact with the outer wall side. By providing a rupture portion that breaks when pulled to the fixing member 1, the fixing member 1 is prevented from being attached to the attachment counterpart in an incomplete state (half-fitted state).

  Next, the configuration of the fixing member according to the embodiment of the present invention will be described in detail with reference to FIG. FIG. 3 is a side view showing the fixing member according to the embodiment of the present invention.

  The fixing member according to the embodiment of the present invention is a through-hole penetrating from the outer wall side to the inner wall side of the mounting partner side on which a fuse circuit component that supplies electric power from the battery and the alternator to an electronic device mounted on the vehicle is mounted. It is a fixing member that is formed integrally with a cap that covers a terminal of an electronic device or the like that is inserted into the hole and fixed to the attachment counterpart, and fixes the cap to the attachment counterpart.

  As shown in FIG. 3, the fixing member 1 includes a tension portion 11 that applies a pulling force to the fixing member 1 toward the inner wall side 63 of the attachment counterpart 61 (see arrow X in FIG. 3, see FIG. 4 described later), and an attachment counterpart. It is comprised from the elastic deformation part 21 elastically deformed inside the through-hole 64 (refer FIG. 4 mentioned later) of the side 61. As shown in FIG.

  The fixing member 1 includes an abutting portion 31 that abuts against an outer wall 62 (see FIG. 4 to be described later) on the attachment counterpart side 61, a breaking portion 41 that breaks between the pulling portion 11 and the abutting portion 31, and a fixing member 1 When the member 1 is attached to the attachment counterpart side 61, it is constituted by an insertion portion 51 that is inserted through a through hole 64 (see FIG. 4 described later).

  The pulling portion 11 includes a distal end portion 12 to be inserted into a through hole 64 (see FIG. 4 described later) on the attachment counterpart side 61, and an inner wall side 63 of the fixing member 1 on the attachment counterpart side 61 (see arrow X in FIG. 3, see below). And a pulling operation portion 13 that serves as a power point for pulling to (see FIG. 4).

  The elastic deformation portion 21 protrudes from the outer periphery of the shaft portion 22 connected to the fracture portion 41 and the shaft portion 22, and passes through the through hole 64 (see FIG. 4 described later) on the attachment counterpart side 61. It has the protrusion part 23 which elastically deforms inside (refer arrow Y of FIG. 3, arrow Z).

  The protruding portion 23 has a substantially triangular shape when viewed from the side, and when the elastically deforming portion 21 moves to the inner wall side 63 of the mounting counterpart side 61, the elastically deforming protruding portion 23 is elastically restored, and the fixing member 1 is prevented from returning to the outer wall side 62 (see FIG. 5 described later).

  The contact portion 31 is a contact surface that comes into contact with the outer wall side 62 when the elastically deforming portion 21 moves from the outer wall side 62 of the attachment counterpart side 61 to the inner wall side 63 (see arrow X in FIG. 3, see FIG. 4 described later). 32.

  The contact surface 32 is formed to be larger than the diameter of a through hole 64 (see FIG. 4 described later) on the attachment counterpart side 61. For this reason, even when the pulling operation portion 13 of the pulling portion 11 applies a pulling force to the fixing member 1 toward the inner wall side 63 (see arrow X in FIG. 3, see FIG. 4 described later) of the attachment counterpart side 61 The surface 32 contacts the outer wall side 62 without penetrating the through hole 64.

  The fracture portion 41 is provided between the tension portion 11 and the elastic deformation portion 21, and the elastic deformation portion is in a state where the contact portion 31 is in contact with an outer wall side 62 (see FIG. 4 described later) of the attachment counterpart side 61. The pulling operation portion 13 is pulled to the inner wall side 63 (see arrow X in FIG. 3 and see FIG. 4 to be described later) with a greater force than when 21 is elastically deformed inside the through hole 64 (see FIG. 4 to be described later). Breaks.

  Further, when the pulling operation portion 13 is broken by pulling it toward the inner wall side 63 (see arrow X in FIG. 3, see FIG. 4 described later), the elastic deformation portion 21 is engaged with the inner wall side 63 around the through hole 64. Breaking while maintaining the state (state shown in FIG. 5 described later).

  As described above, since the breaking portion 41 is provided between the tension portion 11 and the elastic deformation portion 21, the fixing member 1 penetrates the attachment counterpart side 61 when the vicinity of the contact portion 31 is broken. It can prevent coming off from the hole 64 (refer FIG. 4 mentioned later).

  Further, when the elastic deformation portion 21 passes through the through hole 64 (see FIG. 4 described later), the vicinity of the elastic deformation portion 21 is not broken by the frictional force generated inside the through hole 64, so that the elastic deformation portion 21 is surely elastic. The deformable portion 21 can be passed through the through hole.

  The insertion portion 51 is provided between the contact portion 31 and the elastic deformation portion 21, and the elastic deformation portion 21 extends from the outer wall side 62 to the inner wall side 63 (see arrow X in FIG. 3, FIG. 4 described later). If it moves to (refer), it will be located inside the through-hole 64 (refer FIG. 4 mentioned later) of the attachment other party side 61. FIG.

  The tension part 11, the elastic deformation part 21, the fracture | rupture part 41, and the penetration part 51 have a circular cross section. And the diameter a of the tension | pulling part 11 and the diameter b of the insertion part 51 are formed in the substantially the same magnitude | size (for example, about 3 mm).

  Further, the diameter c of the shaft portion 22 of the elastically deformable portion 21 is formed so that the diameter a of the tension portion 11 and the diameter b of the insertion portion 51 are substantially the same size (for example, about 3 mm).

  Further, the protruding portion 23 of the elastically deformable portion 21 is displaced by elastically deforming inside a through hole 64 (see FIG. 4 described later) on the attachment counterpart side 61 (for example, displaced inward by about 1 mm). When the protruding portion 23 is displaced, the diameter d of the protruding portion 23 becomes substantially the same as the diameter c of the shaft portion 22.

  Moreover, the diameter e of the fracture | rupture part 41 is formed smaller than the diameter a of the tension | pulling part 11, the diameter b of the insertion part 51, and the diameter c of the axial part 22 of the elastic deformation part 21 (for example, about 1.5 mm). .

  Here, in the case of the fixing member 1 (see FIGS. 1 and 2) in which the fracture portion 41 is not formed, whether or not the fixing member 1 is attached to the attachment counterpart side 61 in a complete state (normally fitted state). This means that the deformation state of the elastic deformation portion 21 must be visually checked, and the operation for confirming the mounting state of the fixing member 1 becomes complicated.

  However, by providing the breaking member 41 in the fixing member 1, the fixing member 1 is attached to the attachment counterpart side 61 in a complete state (normally fitted state) due to the separation between the tension part 11 and the elastic deformation part 21. This makes it possible to confirm that the fixing member 1 has been attached.

  Further, as described above, the diameter e of the fracture portion 41 is formed to be smaller than the diameter a of the tension portion 11, the diameter b of the insertion portion 51, and the diameter c of the shaft portion 22 of the elastic deformation portion 21. Therefore, the tension portion 11 is moved to the inner wall side 63 (see FIG. 4 to be described later) with a greater force than when the elastic deformation portion 21 is elastically deformed inside the through hole 64 (see FIG. 4 to be described later) with a simple configuration. The breaking portion 41 can be broken by pulling to the right.

  Then, the pulling portion 23 of the elastic deformation portion 21 is elastically deformed by pulling the pulling operation portion 13 of the pulling portion 11 toward the inner wall side 63 (see arrow X in FIG. 3, see FIG. 4 described later) of the attachment counterpart 61. Is smaller than the force at which the breakage portion 41 breaks by pulling the pulling operation portion 13 toward the inner wall side 63 of the attachment counterpart side 61.

  That is, the breakage portion 41 does not break before the elastic deformation portion 21 moves to the inner wall side 63 (see arrow X in FIG. 3, see FIG. 4 described later) of the attachment counterpart side 61.

  Further, the pulling force received by the pulling portion 11 and the insertion portion 51 by pulling the pulling operation portion 13 of the pulling portion 11 toward the inner wall side 63 (see arrow X in FIG. 3, see FIG. 4 described later) is as follows. The protrusion 23 of the elastically deformable portion 21 is larger than the force for elastically deforming the inner side of a through hole 64 (see FIG. 4 described later) on the attachment counterpart side 61 and the force for breaking the breakable portion 41.

  That is, before the elastic deformation part 21 moves to the inner wall side 63 (see arrow X in FIG. 3, see FIG. 4 described later) of the attachment counterpart 61 and before the breaking part 41 breaks, the tension part 11 and the insertion part 51. Will not be damaged.

  As described above, when the elastic deformation portion 21 is elastically deformed inside the through hole 64 (see FIG. 4 described later) in a state where the contact portion 31 is in contact with the outer wall side 62 (see FIG. 4 described later). By pulling the tension part 11 to the inner wall side 63 (see FIG. 4 described later) with a greater force, the breaking part 41 breaks between the tension part 11 and the contact part 31.

  For this reason, the elastically deforming elastic deformation portion 21 is elastically restored and the fixing member 1 is attached to the attachment counterpart side 61 (see FIG. 4 described later) in a complete state (normally fitted state). Can be confirmed by breaking.

  Moreover, when the fracture | rupture part 41 fractures | ruptures, it can confirm that the fixing member 1 was attached to the other party 61 (refer FIG. 4 mentioned later) in the perfect state (normal fitting state). For this reason, although the elastic deformation part 21 is not elastically restored, the fixing member 1 is in an incomplete state (half-fitted state) with respect to the mounting counterpart side 61 as the pulling of the pulling part 11 is stopped. ) Is not attached.

  Accordingly, it is possible to prevent the fixing member 1 from being attached to the attachment counterpart side 61 in an incomplete state.

  Next, the case where the fixing member according to the embodiment of the present invention is attached to the attachment counterpart side will be described in detail with reference to FIGS. 4 to 6. FIG. 4 is a cross-sectional view showing the elastic deformation of the elastic member of the fixing member according to the embodiment of the present invention.

  Moreover, FIG. 5 is sectional drawing which shows the case where the fixing member based on embodiment of this invention is attached to the other party of attachment. FIG. 6 is a perspective view showing the fixing member and the mounting partner side according to the embodiment of the present invention.

  The fixing member 1 configured as described above is attached to the attachment counterpart side 61 as shown in FIGS.

  As shown in FIGS. 4 to 6, a through hole 64 that penetrates from the outer wall side 62 to the inner wall side 63 is formed on the attachment counterpart side 61, and the protruding portion 23 is the shaft portion 22 in the through hole 64. An inclined portion 65 is formed corresponding to the inclined surface protruding from the outer periphery of the outer peripheral surface.

  Further, as shown in FIG. 6, the mounting partner side 61 is mounted with a fuse circuit component 66 that supplies electric power from the battery and the alternator to an electronic device or the like mounted on the vehicle. Has a terminal connection portion 67 to which a terminal of an electronic device or the like that supplies electric power is connected.

  As shown in FIG. 6, the fixing member 1 is integrally formed with a cap 71 that covers a terminal of an electronic device or the like. And while connecting terminals, such as an electronic device covered with the cap 71, to the terminal connection part 67, the fixing member 1 is inserted in the through-hole 64 of the attachment other party 61, and is attached to the attachment other party 61, and the cap 71 is fixed. To do.

  In order to attach the fixing member 1 to the attachment counterpart side 61, as shown in FIGS. 2 to 4, first, the distal end portion 12 is inserted from the outer wall side 62 of the attachment counterpart side 61, and the tension operation portion 13 is inserted into the inner wall side 63 ( The pulling portion 11 is inserted into the through hole 64 by pulling.

  When the tension portion 11 is inserted into the through hole 64, the shaft portion 22 is inserted into the through hole 64 by further pulling the tension operation portion 13 on the inner wall side 63 (see arrow X in FIG. 4).

  After the shaft portion 22 is inserted into the through hole 64, when the pulling operation portion 13 is further pulled to the inner wall side 63 (see arrow X in FIG. 4), the protruding portion 23 is located inside the through hole 64 as shown in FIG. 4. It moves elastically from the outer wall side 62 to the inner wall side 63 (see arrows Y and Z in FIG. 3).

  As shown in FIG. 4, in the through hole 64 on the outer wall side 62, the pulling operation portion 13 is connected to the inner wall side by an inclined portion 65 formed so that the protruding portion 23 corresponds to the inclined surface protruding from the outer periphery of the shaft portion 22. By pulling to 63 (see arrow X in FIG. 4), the protrusion 23 is elastically deformed inside the through hole 64.

  When the pulling operation portion 13 is pulled toward the inner wall side 63 (see arrow X in FIG. 4) in a state where the protrusion 23 is elastically deformed inside the through hole 64, the elastic deformation portion 21 is moved to the inner wall side as shown in FIG. It moves to 63 and penetrates the through-hole 64, and the elastically deformed protrusion 23 is elastically restored.

  As shown in FIG. 5, when the protrusion 23 is elastically restored, the contact surface 32 comes into contact with the outer wall side 62 (see FIG. 4). When the contact surface 32 comes into contact with the outer wall side 62, the fixing member 1 is attached and fixed to the attachment counterpart side 61.

  Then, in a state where the contact surface 32 is in contact with the outer wall side 62, the tension operation unit 13 is moved to the inner wall side 63 (see FIG. 6) with a greater force than when the elastic deformation portion 21 is elastically deformed inside the through hole 64. If it is pulled in the direction of arrow X in FIG.

  Further, when the pulling operation portion 13 is broken by pulling it toward the inner wall side 63 (see arrow X in FIG. 3, see FIG. 4 described later), the elastic deformation portion 21 is engaged with the inner wall side 63 around the through hole 64. Breaking while maintaining the state (the state shown in FIG. 5).

  As described above, since the force of elastic deformation of the protruding portion 23 of the elastic deformation portion 21 is smaller than the force of the breakage portion 41 breaking, the breakage portion 41 breaks after the elastic deformation portion 21 moves to the inner wall side 63. Thus, the tension part 11 and the elastic deformation part 21 are separated.

  Thus, since the fracture | rupture part 41 fractures | ruptures after the elastically deformable part 21 moves to the inner wall side 63, the fixing member 1 is completely in the mounting counterpart side 61 (see FIG. 4 described later) by the fracture of the fracture part 41. It can be confirmed that it is attached in the (normally fitted state).

  Moreover, when the fracture | rupture part 41 fractures | ruptures, it can confirm that the fixing member 1 was attached to the other party 61 (refer FIG. 4 mentioned later) in the perfect state (normal fitting state).

  For this reason, although the elastic deformation part 21 is not elastically restored, the fixing member 1 is in an incomplete state (half-fitted state) with respect to the mounting counterpart side 61 as the pulling of the pulling part 11 is stopped. ) Is not attached.

  Accordingly, it is possible to prevent the fixing member 1 from being attached to the attachment counterpart side 61 in an incomplete state.

  Thus, the fixing member 1 according to the embodiment of the present invention is fixed to the mounting partner side 61 through the through hole 64 penetrating from the outer wall side 62 of the mounting counterpart side 61 to the inner wall side 63. A tension portion 11 that is inserted into the through hole 64 and applies a pulling force to the inner wall side 63; and by pulling the tension portion 11 toward the inner wall side 63, the inner wall side 63 is elastically deformed to the inside of the through hole 64 to The elastic deformation portion 21 that moves to the side 63, the contact portion 31 that makes contact with the outer wall side 62 of the attachment counterpart 61, and the tension portion 11 or the elastic deformation portion when the elastic deformation portion 21 moves to the inner wall side 63 and is elastically restored. 21 when the elastic deformation portion 21 is elastically deformed inside the through-hole 64 in a state where the contact portion 31 is in contact with the outer wall side 62. Pull the tension part 11 to the inner wall side 63 with a large force. Rukoto by, breaking while maintaining the engagement of the elastically deformable portion 21 against the inner wall 63 of the periphery of the through-hole 64.

  Further, in the fixing member 1 according to the embodiment of the present invention, the diameter e of the fracture portion 41 is smaller than the diameter a of the tension portion 11.

  Further, in the fixing member 1 according to the embodiment of the present invention, the fracture portion 41 is provided between the tension portion 11 and the elastic deformation portion 21.

  And according to the fixing member 1 which concerns on embodiment of this invention, the fracture | rupture part 41 has the elastic deformation part 21 elastically deformed inside the through-hole 64 in the state in which the contact part 31 contacted the outer wall side 62. The pulling portion 11 is broken by pulling the pulling portion 11 toward the inner wall side 63 with a larger force than when it is present.

  For this reason, it is confirmed by the fracture | rupture part 41 fracture | rupture that the elastic deformation | transformation part 21 elastically deformed and the fixing member 1 was attached to the attachment other party side 61 in the perfect state (normal fitting state). be able to.

  Moreover, it can confirm that the fixing member 1 was attached to the attachment other party side 61 in the perfect state (normal fitting state) by the fracture | rupture part 41 breaking. For this reason, although the elastic deformation part 21 is not elastically restored, the fixing member 1 is in an incomplete state (half-fitted state) with respect to the mounting counterpart side 61 as the pulling of the pulling part 11 is stopped. ) Is not attached.

  Furthermore, the fixing member 1 is attached to the mounting counterpart side 61 in a complete state (normally fitted state) by providing the fractured portion 41 in the fixing member 1 so that the tension portion 11 and the elastic deformation portion 21 are separated. This makes it possible to confirm that the fixing member 1 has been attached.

  Therefore, it is possible to prevent the fixing member 1 from being attached to the attachment counterpart side 61 in an incomplete state (half-fitted state).

  Further, according to the fixing member 1 according to the embodiment of the present invention, the diameter e of the fracture portion is formed smaller than the diameter a of the tension portion 11, so that the elastic deformation portion 21 has a through hole 64 with a simple configuration. The breaking portion 41 can be broken by pulling the pulling portion 11 to the inner wall side 63 with a larger force than when it is elastically deformed inside.

  Furthermore, according to the fixing member 1 according to the embodiment of the present invention, since the breaking portion 41 is provided between the tension portion 11 and the elastic deformation portion 21, the vicinity of the contact portion 31 is broken. The fixing member 1 can be prevented from coming off from the through hole 64 on the attachment counterpart side 61.

  Further, when the elastic deformation portion 21 passes through the through hole 64 (see FIG. 4 described later), the vicinity of the elastic deformation portion 21 is not broken by the frictional force generated inside the through hole 64, so that the elastic deformation portion 21 is surely elastic. The deformable portion 21 can be passed through the through hole.

  As mentioned above, although the fixing member of the present invention has been described based on the illustrated embodiment, the present invention is not limited to this, and the configuration of each part may be replaced with an arbitrary configuration having the same function. it can.

  In the embodiment of the present invention described above, in the fixing member 1, the diameter e of the fracture portion 41 is smaller than the diameter a of the tension portion 11, the diameter b of the insertion portion 51, and the diameter c of the shaft portion 22 of the elastic deformation portion 21. Although the case where it is formed has been described, it is not limited to this.

  For example, as shown in FIG. 7, the diameter e of the fractured portion 41 ′ is approximately the same as the diameter a of the tension portion 11, the diameter b of the insertion portion 51, and the diameter c of the shaft portion 22 of the elastic deformation portion 21. It may be formed (for example, about 1.5 mm).

  In this case, the force by which the protruding portion 23 of the elastically deforming portion 21 is elastically deformed is smaller than the force by which the breaking portion 41 is broken, and the tensile force received by the tensile portion 11 and the insertion portion 51 is the force by which the protruding portion 23 is elastically deformed. The rupture portion 41 ′ can be formed of a material such as a porous material so that the rupture portion 41 is larger than the breaking force.

  Then, after the elastically deformable portion 21 moves to the inner wall side 63 of the mounting counterpart side 61, the rupture portion 41 ′ is fractured in a state where the abutting portion 31 is in contact with the outer wall side 62 of the mounting counterpart side 61. By doing so, the same effect as the fixing member 1 which concerns on embodiment of this invention mentioned above can be acquired.

  Moreover, although the fracture | rupture part 41 of the fixing member 1 which concerns on embodiment of this invention demonstrated the case where it was provided between the tension | pulling part 11 and the elastic deformation part 21, it is not limited to this. For example, the breaking portion 41 may be provided in the tension portion 11 or the elastic deformation portion 21 as long as it is a portion excluding the contact portion 31 and the insertion portion 51.

  The present invention is extremely useful in providing a fixing member that prevents the fixing member from being attached to the attachment counterpart in an incomplete state.
