(Action / Effect)
Next, the operation and effect of the clip 10 according to this embodiment will be described.
In the above configuration, when the sensor bracket 14 is attached to the back door 12, first, as shown in FIG. 4, the shaft portion 42 of the pin 18 of the clip 10 is inserted into the attachment hole 32 of the sensor bracket 14 and the pin 18. Is inserted into the opening 21 of the clip body 16 to which the packing 17 is attached. At this time, the convex portion 23 of the clip body 16 is inserted into the mounting hole 32 of the sensor bracket 14. Accordingly, the sensor bracket 14 is sandwiched between the head 50 of the pin 18 and the flange portion 22 of the clip body 16, and the clip 10 can be attached to the sensor bracket 14.

  Next, as shown in FIG. 2, the cylindrical portion 20 of the clip body 16 of the clip 10 attached to the sensor bracket 14 is inserted into the attachment hole 30 of the back door 12. At this time, the flange portion 22 of the clip body 16 is brought into contact with the upper peripheral edge portion 12 </ b> A of the mounting hole 30 in the back door 12 with the packing 17 interposed therebetween. Further, the upper surface 28 </ b> A of the claw portion 28 in the engagement piece 24 of the clip body 16 engages with the lower surface peripheral edge portion 12 </ b> B of the mounting hole 30 in the back door 12. For this reason, the sensor bracket 14 can be attached to the back door 12 by the clip 10.

  Further, when the pin 18 of the clip 10 is attached to the clip body 16, a pair of claw portions 60 formed on the shaft portion 42 of the pin 18 so as to protrude outward in the radial direction of the shaft portion 42 are formed in the cylindrical portion of the clip body 16. The pin 18 is engaged with a pair of protrusions 36 formed on the inner peripheral portion 20 so as to prevent the pin 18 from moving in the pulling direction. In addition, a pair of anchors 58 formed so as to be elastically deformable outwardly in the radial direction of the shaft portion 42 at positions shifted by 90 degrees around the shaft relative to the pair of claw portions 60 on the outer periphery of the shaft portion 42 of the pin 18. However, it engages with the pair of through holes 40 formed in the convex portion 23 of the flange portion 22 of the clip body 16 to prevent the pin 18 from moving in the pulling direction with respect to the clip body 16.

  Thus, in the clip 10 of this embodiment, the fitting position between the pair of claw portions 60 and the pair of convex portions 36 and the fitting position between the pair of anchors 58 and the pair of through holes 40 are the same as those of the clip 10. It is shifted along the axial direction and is shifted 90 degrees around the axis. For this reason, the fitting force (extraction force) between the pair of claw portions 60 and the pair of convex portions 36 and the fitting force (extraction force) between the pair of anchors 58 and the pair of through-holes 40 are independently and accurately controlled. It becomes possible to adjust. As a result, the fitting force (extraction force) between the pair of claw portions 60 and the pair of convex portions 36 and the fitting force (extraction force) between the pair of anchors 58 and the pair of through holes 40 are independently and accurately controlled. By adjusting, the clip main body 16 and the pin 18 can be prevented from being damaged when the pin 18 is removed from the clip main body 16 without reducing the pulling force when the pin 18 is removed from the clip main body 16. For example, in a normal use state, the pin 18 can be hardly detached from the clip body 16, and a tool K such as a flat-blade screwdriver is used between the head 50 of the pin 18 and the sensor bracket 14 as shown by a two-dot chain line in FIG. 5. When the pin 18 is inserted between the clip main body 16 and the pin 18 is squeezed out, the clip main body 16 and the pin 18 can be prevented from being damaged.

A convex portion 36 as a first fitting portion is formed on the inner peripheral surface 20D. For this reason, compared with the structure which formed the convex part 36 along the curved wall part 20C with a circular cross section in the cylinder part 20, the deformation | transformation of the convex part 36 to the radial direction outer side of the cylinder part 20 which is a direction which cancels | releases a fitting. The amount increases. As a result, when the pin 18 is removed from the clip body 16, damage to the pair of claws 60 and the pair of protrusions 36 can be prevented.

  Further, in the clip 10 of the present embodiment, as shown in FIG. 8, the upper peripheral edge portion 41 of the through hole 40 as the second fitting portion formed in the flange portion 22 of the clip body 16 extends in the circumferential direction of the flange portion 22. It has a long and long structure, and both end portions 41 </ b> A in the longitudinal direction are connected to the convex portion 23 of the flange portion 22. For this reason, the amount of deformation of the upper peripheral edge portion 41 in the radially outer side can be increased. As a result, when the pin 18 is removed from the clip body 16, damage to the upper peripheral edge 41 of the through hole 40 and the anchor 58 can be prevented.

  Further, in the clip 10 of the present embodiment, as shown in FIG. 2, the upper portion 42 </ b> A of the claw portion 60 in the shaft portion 42 of the pin 18 is formed on the intermediate surface 36 </ b> C of the convex portion 36 in the cylindrical portion 20 of the clip body 16. At the same time, the intermediate surface 60 </ b> C of the claw portion 60 contacts the inner peripheral surface of the flat plate wall portion 20 </ b> B of the cylindrical portion 20. Further, as shown in FIG. 5, the portion 54 </ b> C above the anchor 58 of the elastic piece 54 along the axial direction of the pin 18 is the upper peripheral portion of the through hole 40 that becomes the inner peripheral surface of the opening 21 of the clip body 16. A portion 54 </ b> D below the anchor 58 of the elastic piece 54 along the axial direction of the pin 18 contacts the inner peripheral surface 20 </ b> D of the cylindrical portion 20 of the clip body 16. For this reason, the play between the pin 18 and the clip body 16 is reduced. As a result, compared to the case where the backlash between the pin 18 and the clip body 16 is large, the pin 18 is less likely to be removed from the clip body 16, and the drop force can be prevented from being lowered.

  Further, in the clip 10 of the present embodiment, as shown in FIG. 5, the outer end 44 </ b> B of the wide portion 44 as the tip contact portion formed on the shaft portion 42 of the pin 18 is formed inside the cylindrical portion 20 of the clip body 16. It contacts the peripheral surface 20D. For this reason, the play between the pin 18 and the clip body 16 is further reduced. As a result, compared to a case where the backlash between the pin 18 and the clip main body 16 is large, the pin 18 is less likely to be removed from the clip main body 16, and a drop in the removal force can be prevented.
