  However, in the clip of Patent Document 1, the portion connecting the support column and the elastic engagement leg is thin, and the thin portion (thin portion) is elastically deformed so that the bulging portion is elastic in the radial direction. The diameter can be reduced. For this reason, when removing the clip from the mating member, if the pulling force from the mounting hole of the engaging portion becomes a predetermined value or more, it is conceivable that stress concentrates on the thin portion and is damaged.

  In view of the above facts, an object of the present invention is to obtain a clip that can prevent damage during removal.

  The clip according to the first aspect of the present invention is formed in a head that is locked to the mounting member, and a mating member that is erected on the lower surface of the head so as to be orthogonal to the head and to which the mounting member is mounted.

(Action / Effect)
Next, the operation and effect of the clip according to the embodiment of the present invention will be described.

(Mounting method using clips)
When the clip 10 is used to attach the door trim 15 to the door inner panel 17, first, the upper collar 20 of the clip 10 is inserted into the insertion hole 50 </ b> A of the key hole 50 provided in the locking portion 15 </ b> A of the door trim 15. The lower flange 24 is brought into contact with the back surface of the locking portion 15A, and after the shaft portion 22 is positioned in the insertion hole 50A, the clip 10 is moved with respect to the door trim 15 so that the shaft portion 22 is engaged with the engagement hole. The shaft portion 22 is brought into contact with the inner edge of the engagement hole 50B while being moved into 50B.

  Next, the front end of the engaging portion 14 of the clip 10 locked to the door trim 15 is directed to the door inner panel 17 side, and the engaging portion 14 is pushed into the mounting hole 19 from the front end side (press-fit). As a result, the bulging portions 36A of the pair of elastic engagement legs 36 are pushed by the peripheral edge portion of the mounting hole 19, whereby the pair of elastic engagement legs 36 (the pair of bulging portions 36A) are reduced in diameter. The engaging portion 14 of the clip 10 can be pushed into the mounting hole 19 until 25 is in contact (pressure contact) with the surface of the door inner panel 17.

  Thus, when the engaging portion 14 of the clip 10 is pushed into the mounting hole 19 until the elastic seal portion 25 is in contact with the surface of the door inner panel 17, the pair of elastic engaging legs 36 are in their original state due to their own elasticity. The diameter is expanded. For this reason, the downward inclined surface 36 </ b> C of the pair of elastic engagement legs 36 is in pressure contact with the peripheral edge portion on the back surface side of the mounting hole 19, whereby the door inner panel 17 is formed by the peripheral edge of the elastic seal portion 25 and the pair of elastic engagement legs 36. Can be pinched. As a result, the clip 10 can be attached to the door inner panel 17.

  Therefore, in the clip 10 of the present embodiment, when the pair of elastic engagement legs 36 are inserted into the mounting holes 19 of the door inner panel 17, the thin-walled portion 42 is elastically deformed, so that the pair of elastic engagement legs 36 is easily contracted. Diameter can be. In addition, the width L2 of the connection reinforcing portion 42B is narrower (L1> L2) than the width L1 between the elastic engagement leg 36 and the sub strut portion 32 at the distal end portion of the thin portion 42. For this reason, the elastic deformation range in the radial direction of the bulging portion 36A is widened. As a result, the insertion force when the engaging portion 14 of the clip 10 is pushed into the attachment hole 19 can be reduced. Further, the axial end 42A of the thin portion 42 extends to a position exceeding the bulging portion 36A. For this reason, the elastic deformation range in the radial direction of the bulging portion 36A is widened. As a result, the insertion force when the engaging portion 14 of the clip 10 is pushed into the mounting hole 19 can be further reduced.

  Further, in the clip 10 of the present embodiment, a portion of the elastic engagement leg 36 on the distal end side in the axial direction from the bulging portion 36A is an upward inclined surface 36B in which the bulging amount decreases toward the distal end direction. For this reason, even when the insertion locus when pushing the engaging portion 14 from the distal end side into the attachment hole 19 becomes an arc shape (rotation locus), the clip 10 is inserted into the attachment hole 19 to a position close to the elastic seal portion 25. The engaging portion 14 can be easily inserted. For this reason, an increase in insertion force can be suppressed, and insertion can be performed with an insertion force close to that when the insertion locus is a straight line (vertical direction).

(How to remove the clip)
When the clip 10 is removed from the mounting hole 19 of the door inner panel 17, the engaging portion 14 of the clip 10 is pulled out from the mounting hole 19. As a result, the bulging portions 36 </ b> A of the pair of elastic engagement legs 36 are pushed by the peripheral edge portion of the mounting hole 19, whereby the pair of elastic engagement legs 36 is reduced in diameter. For this reason, a pair of bulging portions 36 </ b> A pass through the mounting holes 19 of the door inner panel 17. As a result, the clip 10 can be removed from the mounting hole 19 of the door inner panel 17.

  At this time, in the clip 10 of the present embodiment, the connection reinforcing portion 42B of the thin portion 42 is connected to the lower surface 25A (head portion 12) of the elastic seal portion 25 and is reinforced. For this reason, when the pair of elastic engagement legs 36 is pulled out from the mounting hole 19, it is possible to prevent the thin portion 42 from being damaged (for example, generation of a crack) by the removal force. Moreover, since the connection reinforcement part 42B of the thin part 42 is connected to the root end 32A of the sub-post part 32, it is possible to prevent the thin part 42 from being damaged even by a larger extraction force.

  Further, in the clip 10 of the present embodiment, a thick portion 44 that is bent in an L shape reaching the head 12 from the elastic engagement leg 36 is formed along the edge of the connection reinforcing portion 42B. For this reason, the connection reinforcement part 42 </ b> B can be reinforced by the thick part 44. As a result, it is possible to prevent the clip 10 from being damaged even with a larger extraction force.
