Inclined surfaces 34 and 34 are formed, respectively, for moving 30 in a direction away from each other along a direction orthogonal to the diameter reducing direction of the pair of elastic locking pieces 20 and 20. Therefore, when the diameter of the pair of elastic locking pieces 20 and 20 is reduced, one engagement claw 32 is moved over the other engagement claw 32 via the inclined surface 34 (see FIG. 5A). ), The engaging claws 32 are engaged with each other (see FIG. 6A). In this embodiment, the inclined surface 34 is formed on both the pair of engaging claws 32, 32, but the inclined surface 34 may be formed on at least one of the engaging claws 32.

  Further, as shown in FIG. 2, the engagement pieces 30 and the engagement pieces 30 are provided at the tips of the engagement pieces 30 and the upper ends of the engagement claws 32, that is, at the end portion on the side of receiving the boss portion 2 of the mounting member 1. A tapered surface 36 that is inclined obliquely downward from the upper end surface of the claw 32 is formed. The tapered surface 36 is pressed by the tip 3 a of the wall 3 of the boss 2 inserted between the pair of elastic locking pieces 20, 20, and the elastic locking pieces 20, The boss portion 2 is guided between the pair of elastic locking pieces 20 and 20 by expanding the diameter 20.

  Next, a procedure for mounting the mounting member 1 to the mounted member 7 using the mounting structure for the mounting member having the above configuration will be described.

  First, in order to attach the clip 10 to the boss 2 projecting from the mounting member 1, the pair of side walls 4, 4 of the boss 2 is orthogonal to the diameter reduction direction of the pair of elastic locking pieces 20, 20. The clip 10 is pushed into the boss portion 2 so that the wall portions 3 of the boss portion 2 are sandwiched by the same pair of elastic locking pieces 20, 20 with the direction to be aligned. Then, the clip 10 is pushed in while being guided by the pair of side walls 4, 4, and the wall portion 3 of the boss portion 2 is inserted between the pair of elastic locking pieces 20, 20.

  Thereafter, the tapered surface 36 of each engagement piece 30 is pressed by the tip 3 a of the wall 3 of the boss 2, and the pair of elastic locking pieces 20, 20 are separated from each other via the engagement piece 30. As it opens, the boss 2 is inserted while the tip of the engagement piece 30 slides on the wall 3.

  And the front-end | tip part 3a of the wall part 3 fits in the boss | hub fitting part 24, and a pair of engagement pieces 30 and 30 are inserted from the both sides of the mounting hole 5 of the boss | hub part 2, and it penetrates in the mounting hole 5. Then, the pair of elastic locking pieces 20 and 20 are elastically restored, and the wall portion 3 of the boss portion 2 is sandwiched between the pair of elastic locking pieces 20 and 20.

  At this time, the pair of engaging pieces 30, 30 are positioned in the mounting hole 5 of the boss portion 2 with their distal end portions in a free state of the pair of elastic locking pieces 20, 20. When a pulling force is applied to the boss portion 2, the pair of engaging pieces 30, 30 are hooked and engaged with the inner periphery of the mounting hole 5, so that the clip 10 can be mounted to the boss portion 2 in a retaining state ( (See FIGS. 4A and 4B).

  Moreover, in this embodiment, since the taper surface 36 which guides the boss | hub part 2 is formed in each engagement piece 30, the wall part 3 of the boss | hub part 2 is inserted between a pair of elastic locking pieces 20 and 20. Then, by pressing the tip 3 a of the wall 3 of the boss 2 against the tapered surface 36 of the engagement piece 30, the pair of elastic locking pieces 20, 20 are opened via the engagement piece 30, The joining piece 30 gets over the wall 3 of the boss 2 and enters the mounting hole 5 so that the clip 10 can be mounted on the boss 2, and the mounting workability of the clip 10 to the boss 2 is improved. Can do.

  In this state, the boss 2 of the mounting member 1 is inserted into the mounting hole 8 of the mounted member 7 together with the clip 10. Then, the outer surfaces of the pair of elastic locking pieces 20, 20 are pressed into the inner periphery of the mounting hole 8, and the pair of elastic locking pieces 20, 20 are pushed in while bending inward. And the inclined surfaces 34 and 34 of each engagement claw 32 of a pair of engagement pieces 30 and 30 contact | abut, and a pair of engagement pieces 30 and 30 are in the diameter reduction direction of the elastic locking piece 20. FIG. While moving away from each other along the orthogonal direction, one engaging claw 32 rides over the other engaging claw 32 and overlaps each other (see FIGS. 5A and 5B). ).

  Thereafter, when the engagement shoulder portion 25 of the elastic locking piece 20 comes out from the back side periphery of the mounting hole 8, the pair of elastic locking pieces 20, 20 are elastically restored, and the engagement shoulder portion is formed on the back side periphery of the mounting hole 8. 25 and 25 engage with each other, and the shoulders 4a and 4a of the side walls 4 of the boss part 2 engage with the front peripheral edge of the attachment hole 8 so that the clip 10 is fixed to the member to be attached. Thus, the attachment member 1 can be attached to the attached member 7 (see FIGS. 6A and 6B).

  In addition, the engagement shoulder portion 25 of the elastic locking piece 20 comes out from the peripheral edge on the back side of the mounting hole 8, the pair of elastic locking pieces 20, 20 are elastically restored, and the engagement shoulder portions 25, 25 become the mounting hole 8. When engaging with the back side peripheral edge, the engaging claws 32, 32 of the pair of engaging pieces 30, 30 may be engaged with each other or overlapped beyond the engaging position. It may be in a state.

  As described above, in this embodiment, the pair of engagement pieces 30, 30 protrude from the same distance from the tips of the pair of elastic locking pieces 20, 20, that is, from the same height position in the drawing (FIG. 4 (B)). Therefore, when the pair of elastic locking pieces 20, 20 are inserted into the mounting hole 8, the engaging claws 32, 32 come into contact with each other, and the pair of elastic locking pieces 20, 20 are connected to the pair of elastic engagements. Since it can make it easy to bend in the direction orthogonal to the diameter reduction direction of the stop pieces 20 and 20, a pair of engagement pieces 30 and 30 can be engaged with a comparatively low insertion force.

  Further, in this embodiment, when the elastic locking piece 20 is inserted into the mounting hole 8 and the pair of elastic locking pieces 20, 20 has a reduced diameter, the engagement claws 32 of the pair of engagement pieces 30, 30. , 32 come into contact with each other via the inclined surfaces 34, 34 and get over the mating engagement pawl 32, so that the pair of engagement pieces 30, 30 can smoothly get over each other to be engaged or overlapped. Can be.

  Furthermore, in this embodiment, when the pair of elastic locking pieces 20, 20 is inserted into the mounting hole 8, the engagement piece 30 is disposed at a portion of the elastic locking piece 20 near the base end where the bending allowance is large. Therefore, the pair of engagement pieces 30 can be easily engaged with each other.

  Further, in this embodiment, when the elastic locking piece 20 is inserted into the mounting hole 8 of the mounted member 7, it is strongly pressed against the inner periphery of the mounting hole 8, and inside the engagement shoulder 25 having a large deflection margin. Since the engagement piece 30 is provided, the pair of engagement pieces 30 and 30 can be reliably engaged with each other when the diameter of the pair of elastic locking pieces 20 and 20 is reduced.

  Then, when it is desired to remove the mounting member 1 from the mounted member 7 for reasons of repair, maintenance, replacement, etc., the mounting member 1 is attached to the mounted member 7 as shown by the arrow in FIG. Pull strongly. Then, the engagement shoulder portion 25 is pressed against the inner periphery of the attachment hole 8 of the member 7 to be attached, and the pair of elastic locking pieces 20 and 20 are further bent inward and reduced in diameter, while being reduced in diameter. The clip 10 and the boss 2 of the attachment member 1 are pulled out, and the attachment member 1 can be detached from the attachment member 7.

  At this time, the pair of elastic locking pieces 20, 20 are elastically restored, and the pair of engagement pieces 30, 30 are engaged with each other via the engagement claws 32, 32 in the mounting hole 5. Therefore, the clip 10 can be maintained firmly attached to the boss portion 2 of the mounting member 1, and the boss of the mounting member 1 can be maintained from the mounting hole 8 of the mounted member 7 as described above. When the part 2 and the clip 10 are pulled out, the clip 10 can be prevented from being detached from the boss part 2 and remaining in the mounting hole 8 or falling to an unintentional place.

  That is, when the engaging claws 32 and 32 of the pair of engaging pieces 30 and 30 are engaged with each other, when the boss portion 2 and the clip 10 are pulled out from the mounting hole 8, Even if bending stress or stress in the torsional direction is applied, the pair of engagement pieces 30 and 30 can be firmly engaged, and the clip 10 is not attached to the boss portion 2 and is securely attached. Can be held.

  Further, the pair of engaging pieces 30, 30 are inserted in a state of passing through the mounting holes 5 of the boss portion 2 of the mounting member 1 with the mounting member 1 attached to the mounted member 7 via the clip 10. Since they are engaged with each other via the engaging claws 32, 32 (see FIGS. 6A and 6B), the mounting member 1 is attached from the mounting hole 8 of the mounted member 7 as described above. When the boss part 2 and the clip 10 are pulled out, the pair of engagement pieces 30 and 30 are firmly engaged with the mounting hole 5 of the boss part 2 so that the clip 10 is detached from the boss part 2 more reliably. Can be prevented.

  When removing the clip 10 from the boss portion 2, the knob pieces 27 and 27 are picked and the pair of elastic locking pieces 20 and 20 are bent inward so that the engagement claws 32 and 32 are engaged with each other. While releasing the state and maintaining the state, the clip 10 is moved to the tip end side in the axial direction of the wall portion 3 of the boss portion 2, and the pair of engagement pieces 30, 30 are pulled out from the mounting hole 5 of the boss portion 2. Thus, the clip 10 can be removed from the boss portion 2.
