Then, the attachment member 41 is further pushed up in the direction of the arrow X6 so that the upper end portion of the clip body 2 is brought into contact with the lower end surface of the attached member 45.

  As a result, the first stud bolt 46 is inserted into the clip body 2 while spreading the pair of first locking members 7, 7 and the pair of second locking members 8, 8 facing each other. A tip end portion 46 </ b> A in which the thread groove of the stud bolt 46 is not cut is inserted into the through hole 33. Further, each of the three first locking ribs 14 having a substantially triangular shape in a side view of the pair of first locking members 7 and 7 facing the thread groove of the first stud bolt 46 is caused by the elastic restoring force of the arm member 13. It meshes with the thread groove of the first stud bolt 46.

  In addition, any one of the three second locking ribs 15 each having a substantially trapezoidal shape in a side view of the pair of second locking members 8 and 8 facing the thread groove of the first stud bolt 46 is elastically restored by the arm member 13, respectively. The first stud bolt 46 is engaged with the screw groove by force. As a result, the attachment member 41 is locked to the first stud bolt 46 erected on the attached member 45 via the stud bolt fixing clip 1 with a high locking force.

  In addition, as shown in FIG. 15, when the upper end of the clip body 2 is brought into contact with the lower end surface of the attached member 45, each pressing piece 18 is pressed by the lower end surface of the attached member 45, The elastic arm 17 is bent downward. As a result, the substantially triangular pressing protrusion 20 formed on the edge of each pressing piece 18 moves downward, and each contact protrusion 25 formed on the end edge of each contact piece 23. The contact piece 23 is moved while being in contact with the inclined surface, and the contact pieces 23 are bent outward (in the direction of the arrow X7). In addition, since each protrusion member 21 is each supported by the reinforcement rib 22, the lower surface side does not bend in the downward direction.

  When the pressing protrusions 20 are further moved downward and separated from the contact protrusions 25, the contact pieces 23 are moved in the clip body 2 side direction (in the direction of the arrow X8) by the elastic restoring force. Due to elastic deformation, each contact protrusion 25 comes into contact with each pressing piece 18 vigorously. Therefore, at the moment when the upper end portion of the clip body 2 is brought into contact with the lower end surface of the attached member 45 and pushed to the attachment position of the first stud bolt 46, each contact projection 25 is detached from each press projection 20. Then, it strikes each pressing piece 18 vigorously.

  Therefore, at that time, it is possible to confirm a click feeling and a click sound (for example, a “chat” sound) transmitted to the operator, and to the first stud bolt 46 of the stud bolt fixing clip 1. Installation completion is confirmed. Further, since each pressing piece 18 presses the attached member 45 by the elastic restoring force of each elastic arm 17, it is possible to prevent rattling in the axial direction of the stud bolt fixing clip 1 with respect to the first stud bolt 46. .

  In the state shown in FIG. 15, a hexagon wrench is inserted into the hexagonal section tool hole 32 formed in the bottom surface of the clip body 2 of the stud bolt fixing clip 1 attached to the attachment member 41, and the hexagon Rotate the wrench counterclockwise as seen from below. Thereby, since the fixing clip 1 for stud bolts rotates counterclockwise as viewed from the lower side with respect to the first stud bolt 46, each of the first locking ribs 14 of the pair of first locking members 7, 7 and The second locking ribs 15 of the pair of second locking members 8, 8 move downward along the thread groove of the first stud bolt 46, disengage from the thread groove, and are unlocked. The

  Moreover, since the width of each arm member 13 is formed to be the same as the width of each first locking member 7 and each second locking member 8, the arm member 13 has sufficient strength in the twisting direction. . Therefore, when the stud bolt fixing clip 1 rotates counterclockwise, the first locking ribs 14 and the second locking ribs 15 reliably rotate along the thread groove of the first stud bolt 46. Rotation deviation does not occur.

  Next, the stud bolt fixing clip 1 attached to the attaching member 41 as described above is provided with two different screw pitches standing on the attached member 45 which is a metal plate (body) constituting the body of the automobile. A state where the stud bolt is attached to the second stud bolt 48 having the larger screw pitch will be described with reference to FIGS. 16 and 17.

  FIG. 16 is a partial cross-sectional view showing a state before the stud bolt fixing clip 1 attached to the attachment member 41 is attached to a second stud bolt 48 having a larger screw pitch of two stud bolts having different screw pitches. It is. FIG. 17 is a cross-sectional view showing a state in which the stud bolt fixing clip 1 attached to the attachment member 41 is attached to a second stud bolt 48 having a larger screw pitch of two stud bolts having different screw pitches. .

  16 and 17, the bolt insertion port 4 of the stud bolt fixing clip 1 attached to the attachment member 41 is opposed to the second stud bolt 48, and the attachment member 41 is pushed up in the direction of the arrow X8, A tip end 48 </ b> A in which the thread groove of the second stud bolt 48 is not cut is inserted into the bolt insertion port 4. Then, the mounting member 41 is further pushed up in the direction of the arrow X9 so that the upper end portion of the clip body 2 is brought into contact with the lower end surface of the mounted member 45.

  As a result, the second stud bolt 48 is inserted into the clip body 2 while expanding the pair of first locking members 7, 7 and the pair of second locking members 8, 8 facing each other. The front end 48 </ b> A in which the thread groove of the stud bolt 48 is not cut is inserted into the through hole 33. Also, any one of the three first locking ribs 14 each having a substantially triangular shape in a side view of the pair of first locking members 7 and 7 facing the thread groove of the second stud bolt 48 is elastically restored by the arm member 13, respectively. The screw engages with the thread groove of the second stud bolt 48 by force.

  Also, each of the three second locking ribs 15 having a substantially trapezoidal shape in a side view of the pair of second locking members 8, 8 facing the thread groove of the second stud bolt 48 is caused by the elastic restoring force of the arm member 13. It meshes with the thread groove of the second stud bolt 48. Thereby, the attachment member 41 is locked with a high locking force to the second stud bolt 48 erected on the mounted member 45 via the stud bolt fixing clip 1.

  In addition, as shown in FIG. 16, when the upper end portion of the clip body 2 is brought into contact with the lower end surface of the attached member 45, each pressing piece 18 is pressed by the lower end surface of the attached member 45, The elastic arm 17 is bent downward. As a result, the substantially triangular pressing protrusion 20 formed on the edge of each pressing piece 18 moves downward, and each contact protrusion 25 formed on the end edge of each contact piece 23. The contact piece 23 is moved while being in contact with the inclined surface, and the contact pieces 23 are bent outward (in the direction of the arrow X7). In addition, since each protrusion member 21 is each supported by the reinforcement rib 22, the lower surface side does not bend in the downward direction.

  When the pressing protrusions 20 are further moved downward and separated from the contact protrusions 25, the contact pieces 23 are moved in the clip body 2 side direction (in the direction of the arrow X8) by the elastic restoring force. Due to elastic deformation, each contact protrusion 25 comes into contact with each pressing piece 18 vigorously. That is, at the moment when the upper end portion of the clip body 2 is brought into contact with the lower end surface of the attached member 45 and pushed to the attachment position of the second stud bolt 48, each contact projection 25 is detached from each press projection 20. Then, it strikes each pressing piece 18 vigorously.

  Therefore, at this time, it is possible to confirm a click feeling and a click sound (for example, a “chat” sound) transmitted to the operator, and the stud bolt fixing clip 1 is connected to the second stud bolt 48. Installation completion is confirmed. Further, since each pressing piece 18 presses the attached member 45 by the elastic restoring force of each elastic arm 17, it is possible to prevent rattling in the axial direction of the stud bolt fixing clip 1 with respect to the second stud bolt 48. .

  In the state shown in FIG. 16, a hexagon wrench is inserted into the hexagonal section tool hole 32 formed on the bottom surface of the clip body 2 of the stud bolt fixing clip 1 attached to the attachment member 41, and the hexagon Rotate the wrench counterclockwise as seen from below. As a result, the stud bolt fixing clip 1 rotates counterclockwise as viewed from the lower side with respect to the second stud bolt 48, so that the first locking ribs 14 of the pair of first locking members 7, 7 and The second locking ribs 15 of the pair of second locking members 8, 8 move downward along the thread groove of the second stud bolt 48, disengage from the thread groove, and are unlocked. The

  Moreover, since the width of each arm member 13 is formed to be the same as the width of each first locking member 7 and each second locking member 8, the arm member 13 has sufficient strength in the twisting direction. . Therefore, when the stud bolt fixing clip 1 is rotated in the counterclockwise direction, the first locking ribs 14 and the second locking ribs 15 are reliably rotated along the thread groove of the second stud bolt 48. Rotation deviation does not occur.

  Therefore, as described above, in the stud bolt fixing clip 1 according to this embodiment, when the first stud bolt 46 is inserted into the bolt insertion port 4, the pair of first locking members 7, 7 Each of the three formed first locking ribs 14 can be engaged with the thread groove of the first stud bolt 46. Further, when the second stud bolt 48 is inserted into the bolt insertion port 4, the three second locking ribs 15 formed on the pair of second locking members 8, 8 are connected to the second stud bolt 48. Can be engaged with the thread groove.

  Accordingly, each of the three first locking ribs 14 or the pair of pairs formed on the pair of first locking members 7 and 7 with respect to each of the first stud bolt 46 or the second stud bolt 48 having different screw pitches. The three second locking ribs 15 formed on the second locking members 8 and 8 can be securely engaged with each other and reliably attached with a high locking force.

  In addition, a pair of first locking members 7 each having three first locking ribs 14 engaging with the thread grooves of the first stud bolt 46 having the smaller screw pitch of the two stud bolts having different screw pitches. Is arranged on the side close to the bolt insertion port 4. Thus, even when the stud bolts 46 and 48 are inserted halfway into the bolt insertion port 4 for positioning when the stud bolt fixing clip 1 is attached to the stud bolts 46 and 48, the bolts are inserted. The first locking ribs 14 arranged on the side close to the opening 4 can be securely meshed with or engaged with the stud bolts 46 and 48, and the positioning can be easily performed. It becomes.

  The pair of first locking members 7 and 7 are shifted in the axial direction of the first stud bolt 46 by a half pitch of the screw pitch of the first stud bolt 46 with which each first locking rib 14 is engaged. . Further, the pair of second locking members 8 and 8 are shifted in the axial direction of the second stud bolt 48 by a half pitch of the screw pitch of the second stud bolt 48 with which each second locking rib 15 is engaged. . Accordingly, the first locking ribs 14 of the first locking members 7 or the second locking ribs 15 of the second locking members 8 are securely engaged with the stud bolts 46 and 48, respectively. Thus, it can be securely attached with a higher locking force.

  Furthermore, by forming the width of each arm member 13 to be the same as the width of each first locking member 7 and each second locking member 8, the rigidity of the arm member 13 in the width direction can be improved. Thus, each first locking member 7 and each second locking member 8 can be reliably brought into contact with the thread of each stud bolt 46, 48.

  Further, when the stud bolts 46 and 48 are pushed into the bolt insertion port 4 to the mounting position, the pressing pieces 18 are pressed by the mounted members 45, and the pressing protrusions 20 come into contact with the contact protrusions 25. While moving toward each projecting member 21 and bending each contact piece 23 outward with respect to the central axis of the bolt insertion port 4, each pressing projection 20 is moved from each contact projection 25. The contact protrusions 25 are separated from each other, and the pressing pieces 18 are urged against each other by the elastic restoring force of the contact pieces 23.

  As a result, at the moment when each stud bolt 46, 48 is pushed to the mounting position, the operator can select each stud bolt 46, The completion of attachment to 48 can be clearly recognized, and the stud bolt fixing clip 1 can be securely attached to the stud bolts 46 and 48.

  In addition, this invention is not limited to the said Example, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this invention.
