(See FIGS. 4B and 4C). Further, as shown in FIGS. 3 and 4 (c), one end portion side of the side wall portions 53, 53 is suspended from the back surface 27 of the head portion 20. From the middle portion of the stem portion 30, The diameter gradually decreases toward the distal end portion 32, and the other end portion opposite to the head portion 20 is connected to both side surfaces in the thickness direction of the stem portion 30.

  Further, as shown in FIG. 4B, the curved portion of the long hole 5 is formed at the distal end portion of the side wall portion 53 in the extending direction along the stem portion longitudinal direction and on the outer peripheral surface near the head portion 20. A curved surface portion 53a is provided along the six curved shapes.

  Further, as shown in FIG. 5, when the pair of elastic engagement pieces 40, 40 are viewed from a direction orthogonal to the bending direction, the pair of elastic engagement pieces 40, 40 are not bent and deformed. The pair of elastic engagement pieces 40 and 40 and the base portions 51 and 51 constituting the rotation restricting portion 50 are configured so as not to overlap each other.

  As shown in FIG. 11, in this embodiment, the short axis S2 of the long hole 5 (a line segment passing through the center C of the long hole 5 and perpendicular to the long axis S1, the same applies to the following description). On the other hand, the elastic engagement piece 40 is arranged on one end side in the long axis direction of the long hole 5, and the rotation restricting portion 50 is arranged on the other end side in the long axis direction of the long hole 5. The rotation restricting portion 50 extends across the short axis S2 of the long hole 5, that is, from the other end side in the long axis direction of the long hole 5 to one end of the long hole 5 in the long axis direction beyond the short axis S2. It arrange | positions with the length which reaches the part side (refer FIG. 11). Thereby, the rotation control effect of the clip 10 with respect to the long hole 5 can be heightened.

  In addition, the shape of the said rotation control part is an illustration, Of course, even if it is shapes other than this embodiment, it is good.

  By the way, in this embodiment, as shown in FIG.4 (b) and FIG. 11, with respect to the long axis S1 of the long hole 5, it becomes with respect to a pair of elastic engagement pieces 40 and 40 arrange | positioned on both sides thereof. Thus, a pair of L-shaped cross-section plate ribs (base 51 and side wall 53) that constitute the rotation restricting portion 40 are arranged adjacent to each other. However, when the pair of elastic engagement pieces 40, 40 are arranged in a rotationally symmetric position with respect to the long axis S1 of the long hole 5, the pair of L constituting the rotation restricting portion 40 corresponding thereto. The plate-shaped plate ribs (base 51 and side wall 53) may be arranged so as to be rotationally symmetric with respect to the long axis S1 of the long hole 5. That is, the rotation restricting portion only needs to be provided at a position adjacent to the pair of elastic engagement pieces along the long axis direction of the long hole 5.

  In the clip 10, as shown in FIGS. 3, 4 (c) and 6, the first convex portion 47 is formed on the side edge 45 on the rotation restricting portion 50 side of each elastic engagement piece 40. Are protruded, and the side surfaces of the rotation restricting portion 50 on the elastic engagement piece 40 side, that is, the side surfaces 51 a and 51 a on the elastic engagement piece 40 side of the base portions 51 and 51 constituting the rotation restricting portion 50. In addition, a structure is provided in which the second convex portions 55 and 55 project.

  Further, as shown in FIG. 11, the first convex portion 47 is closer to the head 20 than the second convex portion 55 in a state where the engaging portion (here, the engaging portion 41) is engaged with the back side of the long hole 5. Further, when viewed from the axial direction of the stem portion 30, the second convex portion 55 is arranged so as to overlap.

  As shown in FIGS. 3 and 8B, the first convex portion 47 in this embodiment is a side edge portion 45 of the elastic engagement piece 40, and includes an engagement portion 41 and an engagement portion 42. Projecting from the vicinity of the boundary. Furthermore, a taper surface 47 a that gradually increases in height toward the tip end portion 32 of the stem portion 30 is formed on the surface of the first convex portion 47 on the head 20 side, and on the opposite surface thereof Is formed with an engagement surface 47b perpendicular to the side edge 45 (see FIG. 4C). Then, as shown in FIGS. 8A, 9A, and 10A, the elastic engagement piece 40 approaches and separates from the side surface of the stem portion 30 with the base end portion as a fulcrum. When bent and deformed in the direction, the first convex portion 47 draws an arc-shaped movement locus.

  On the other hand, as shown in FIG. 4, FIG. 5, and FIG. 8A, the second convex portion 55 is formed on the side surface 51 a of the base portion 51 of the rotation restricting portion 50 with the first convex portion 47 of the elastic engagement piece 40. It is formed along the width direction of the side surface 51a so as to extend in an arc shape along the movement locus. Moreover, the width direction base end part of this 2nd convex part 55 is connected with the thickness direction one side surface of the said stem part 30 (refer FIG.4 (b)). Further, an engagement surface 55a perpendicular to the side surface 51a of the base 51 is formed on the surface of the second convex portion 55 on the head 20 side, and the stem 30 is formed on the opposite surface thereof. A tapered surface 55b whose height gradually decreases toward the distal end portion 32 is formed (see FIG. 4C). The engaging surface 55a of the second convex portion 55 is adapted to engage with the engaging surface 47b of the first convex portion 47.

  The first convex portions 47 and 47 are, as shown in FIG. 4, the second convex portion 55 in a state where the stem portion 30 and the pair of elastic engagement pieces 40 and 40 are not inserted into the long hole 5. , 55 and an upper position closer to the head 20 and outside the width direction base end portions of the second convex portions 55, 55 (see FIG. 7), the mounted members having different plate thicknesses When the stem portion 30 and the pair of elastic engagement pieces 40, 40 are inserted into the long holes 5, 1a, 1b, the elastic engagement pieces 40 are bent and deformed, and the first convex portions 47, 47 become the second convex portions. It moves along the circular arc shape of the portions 55, 55 while maintaining a certain clearance between the first convex portion 47 and the second convex portion 55 (FIGS. 8A, 9A, 10). (See (a)). In this state, a force in a direction in which the pair of elastic engagement pieces 40, 40 are pulled out from the long hole 5 (hereinafter referred to as "pull-out force"). When also in the description) acts, as shown in FIG. 12, the first convex portion 47 and if the second convex portion 55 is adapted to engage.

  Note that the shapes and positions of the first convex portion 47 and the second convex portion 55 are merely examples, and the first convex portion is the second convex portion in a state where the engaging portion is engaged with the back side of the long hole. There is no particular limitation as long as it is configured to overlap the second convex portion when viewed from the axial direction of the stem portion and closer to the head.

  Next, a method of using the clip 10 having the above configuration will be described.

  That is, as shown in FIG. 1, the mounting member 3, which is a corrugated tube, is disposed in the receiving part 21 of the head 20, the opening / closing part 23 is closed via the hinge part 22, and the locking piece 23 a is The attachment member 3 is held by the head 20 by being locked to the locked portion 21a.

  In this state, the longitudinal direction of the stem portion 30 is aligned with the long axis direction of the long hole 5 formed in the mounted member 1, and in this state, the stem portion 30 and the pair of elastic members from the front side of the long hole 5. The pieces 40 and 40 are inserted.

  Then, the outer peripheral surface of the elastic engagement piece 40 is pressed to the inner periphery of the long hole 5, and the pair of elastic engagement pieces 40, 40 are bent and deformed in the directions approaching both side surfaces of the stem portion 30, respectively. The rotation restricting portion 50 enters the elongated hole 5. In this embodiment, the engaging portions 43, 42, 41 are sequentially pulled out from the back side of the long hole 5, the pair of elastic engaging pieces 40, 40 are elastically restored, and the uppermost engaging portion 41 is moved. While engaging with the back side periphery of the long hole 5, the flange part 25 of the head part 20 contact | abuts elastically with the front side periphery of the long hole 5 (refer FIG. 8). As a result, the clip 10 is attached to the long hole 5, and the attachment member 3 can be attached to the attached member 1 via the clip 10.

  Further, as described above, when the elastic engagement piece 40 is bent and deformed, the first convex portion 47 of the elastic engagement piece 40 moves along the arc shape of the second convex portion 55 having an arc shape, It is arranged closer to the head 20 than the two convex portions 55 and overlapping the second convex portion 55 (see FIGS. 8 and 11).

  In the above description, the case where the clip 10 is attached to the elongated hole 5 of the thin attached member 1 has been described. However, as shown in FIG. When the clip 10 is attached to one long hole 5, the engaging portion 42 engages with the peripheral edge of the back side of the long hole 5, and as shown in FIG. When the clip 10 is attached to the long hole 5 of the thick attached member 1 b, the engaging portion 43 is engaged with the rear side periphery of the long hole 5.

  And this clip 10 has the following effects.

  That is, in this clip 10, as shown in FIG. 11, in the state where the engaging portion 41 of the elastic engaging piece 40 is engaged with the back side periphery of the long hole 5, the first convex portion 47 is the second convex portion. It is disposed closer to the head 20 than the portion 55 and overlaps the second convex portion 55. Therefore, in this state, the pulling force from the long hole 5 acts on the pair of elastic engagement pieces 40, 40 by pulling the attachment member 3 held by the head 20 on the long hole front side, etc. When the rotation restricting portion 50 arranged in the hole 5 tries to lift from the front side of the long hole 5, the first convex portion 47 and the second convex portion 55 engage with each other as shown in FIG. As a result, the rotation restricting portion 50 is restrained from floating from the front side of the long hole 5, and the pair of elastic engagement pieces 40, 40 are hardly affected by the twisting force due to the pulling force. On the other hand, the clip 10 can be attached with less backlash.

  In addition, when the clip 10 is attached to the long holes 5 of the attached members 1a and 1b having different thicknesses as shown in FIGS.

  Further, in this embodiment, as shown in FIG. 4B and FIG. 11, the base portions 51, 51 constituting the rotation restricting portion 50 protrude in the direction along the short axis S <b> 2 of the long hole 5. Since the rotation restricting portion 50 has a structure provided so as to straddle the short axis S2 of the long hole 5, the rotation restricting effect of the clip 10 by the rotation restricting portion 50 can be further improved.

  In addition, when the rotation restricting portion 50 is formed large in this way, the elastic engagement piece 40 tends to be relatively small, and the length of the engagement portions 41, 42, 43 provided on the elastic engagement piece 40 is long. There is a concern that the engagement amount (lapping margin) with respect to the back side of the hole 5 is reduced, and the engagement force of the clip 10 with respect to the long hole 5 is reduced. However, even in such a case, when a pulling force is applied to the clip 10, the first convex portion 47 of the elastic engagement piece 40 and the second convex portion 55 of the rotation restricting portion 50 are engaged with each other. Therefore, deformation of the elastic engagement piece 40 can be suppressed, and the clip 10 can be firmly engaged with the long hole 5.

  By the way, as described above, as shown in FIGS. 8A, 9A, and 10A, the thickness of the mounted member 1 provided with the long holes 5 may be thin or thick. When it changes, the elastic engagement piece 40 will bend and deform | transform according to it, and the engaging part 41,42,43 will engage with the back side of the long hole 5. FIG.

  In contrast, in this embodiment, as shown in FIGS. 4, 5, and 8 (a), the second convex portion 55 provided on the rotation restricting portion 50 is elastically coupled to the side surface 51 a of the base portion 51. Since it is formed so as to extend in an arc shape along the movement locus of the first convex portion 47 of the joint piece 40, the thickness of the mounted members 1, 1a, 1b provided with the long holes 5 changes, Even when the amount of deformation of the elastic engagement piece 40 changes, the first convex portion 47 on the elastic engagement piece 40 side is always closer to the head 20 than the second convex portion 55 on the rotation restricting portion 50 side. And since it will arrange | position with overlapping, the 1st convex part 47 and the 2nd convex part 55 can be reliably engaged when the clip 10 is pulled out.

  Furthermore, in this embodiment, the curved portion having a curved shape is formed so that the inner diameter of the long hole 5 formed in the attached member 1 is gradually narrowed toward the long axial end. 6 and 6 are formed, and correspondingly, the engaging portions 41, 42, 43 of the pair of elastic engaging pieces 40, 40 have a shape along the curved shape of the curved portion 6 of the long hole 5. (See FIG. 4B and FIG. 11). Therefore, when the stem portion 30 and the pair of elastic engagement pieces 40, 40 are inserted into the long hole 5, the engagement portions 41, 42, 43 of the elastic engagement piece 40 are behind the curved portion 6 of the long hole 5. Therefore, it is possible to secure a large lap allowance between the engaging portions 42 and 43. In this engaged state, the peripheral portions of the engaging portions 41, 42, 43 are pressed against the curved portion 6 of the long hole 5, and the pair of elastic engaging pieces 40, 40 are close to the rotation restricting portion 50 side. Therefore, the engagement state between the first convex portion 47 on the elastic engagement piece 40 side and the second convex portion 55 on the rotation restricting portion 50 side is firmly held, so that the two convex portions 47 and 55 It is possible to prevent the engagement from being released.
