The pair of elastic strip-shaped pieces 31 and 31 integrally formed with the engagement receiving pieces 50 and 50 following the bending deformation of the 50 and 50 are also on the first plate portion 20 side as shown by the arrow F2 in FIG. Each bends and deforms toward. As described above, in the member mounting structure and the clip 10, the pair of engaging protrusions 75 and 75 of the pins 70 are engaged with the receiving portions 51 and 51 of the pair of engaging receiving pieces 50 and 50. Since not only the pair of elastic strips 31 and 31 but also the pair of engagement receiving pieces 50 and 50 are bent respectively, the stress concentration applied to the engaging receiving pieces 50 and the elastic strips 31 is relaxed and elastic. The elastic force of the strip-shaped piece 31 can be maintained for a long period of time, and the clip 10 can be stably sandwiched by the first member 1.

Further, since the receiving portion 51 of the engaging receiving piece 50 has a concave shape, the engaging protrusion 75 fits into the concave receiving portion 51 when the pin 70 is rotated, so that the engaging state is engaged. Can be easily grasped, and the engaged state can be stably maintained.

Further, in this embodiment, the extension amount of the pair of engagement receiving pieces 50, 50 from the opposite inner sides 31a, 31a of the pair of elastic strip-shaped pieces 31, 31 is a pin, as shown in FIG. When the 70 is rotated, the tip of the engaging protrusion 75 is set to have a length that does not reach the inner side 31a of the elastic band-shaped piece 31, so that the pushing by each engaging protrusion 75 accompanying the rotation of the pin 70 The pressure can be reliably applied to each engagement receiving piece 50 to make it easy to bend and deform each engaging receiving piece 50 (when the engaging receiving piece 50 is short, the engaging receiving piece 50 can be easily deformed when the pin 70 is rotated. The portion 75 directly hits the elastic strip-shaped piece 31 and the engaging receiving piece 50 is less likely to bend and deform), and the stress concentration on the engaging receiving piece 50 and the elastic strip-shaped piece 31 can be further relaxed.

Further, in this embodiment, as shown in FIGS. 3 and 4, each engaging receiving piece 50 has a receiving portion 51 extending from the inner side 31a of each elastic strip-shaped piece 31 and a receiving portion 51 extending from the receiving portion 51. With the extended guide portion 53, when the pin 70 is rotated from the state shown in FIG. 7, the engaging protrusion 75 rotates while being in contact with the guide portion 53 and engages with the receiving portion 51. It is configured to fit. Therefore, when the pin 70 is rotated, the pin 70 can be rotated while being guided by the guide portion 53, and the engaging protrusion portion 75 is rotated while being in contact with the guide portion 53 to flex the guide portion 53. Since the entire engagement receiving piece 50 is engaged while being bent little by little via the guide portion 53, the rotation of the pin 70 can be guided and easily rotated, and the rotation operation of the pin 70 can be performed. By reducing the force, the engaging protrusion 75 can be smoothly engaged with the receiving portion 51 of the engaging receiving piece 50.

Further, in this embodiment, a notch portion 57 is formed between the elastic strip-shaped piece 31 and the guide portion 53 so that the tip end side of the guide portion 53 is separated from the elastic strip-shaped piece 31. Since the tip of the notch 57 close to the receiving portion 51 has a length that does not reach the receiving portion 51, the guide portion 53 can be made more flexible. Further, since the tip of the notch 57 close to the receiving portion 51 has a length that does not reach the receiving portion 51, the receiving portion 51 of the engaging receiving piece 50 can be easily formed.

Further, in this embodiment, as shown in FIG. 4, guide portions 53 and 53 extend from both sides of each receiving portion 51, respectively, and guide portions 53 facing each other in the parallel direction of the pair of elastic strips 31, 31. , 53 are separated from each other via a gap, and this gap forms a protrusion insertion passage 62. According to this aspect, the engaging protrusion 75 of the pin 70 is passed through the protrusion insertion passage 62 to be positioned on the side of the second plate portion 30 opposite to the first plate portion 20, and then the pin 70. Is rotated in any of the directions of arrows R1 and R2 in FIG. 7, the engaging protrusion 75 can be guided by the guide portion 53, and the directionality of the pin 70 in the rotation direction can be eliminated. Further, since the guide portions 53, 53 of the respective receiving portions 51 facing each other in the parallel direction of the pair of elastic strip-shaped pieces 31, 31 are separated from each other through the gap, the respective receiving portions 51 are further bent. It can be easily deformed (when the pair of receiving portions 51 and 51 are connected via the guide portion 53, the pair of receiving portions 51 and 51 are less likely to bend).

Further, in this embodiment, as shown in FIG. 4, a pair of guide portions 53, 53 extend from both sides of each receiving portion 51, and the inner circumferences 53a, 51a of each of the guide portions 53 and the receiving portion 51 are extended. However, since the shape conforms to the outer circumference of the shaft portion 73 of the pin 70, the inner circumference 53a of each guide portion 53 and the inner circumference 51a of the receiving portion 51 are formed during rotation of the pin 70 as shown in FIG. As a guide for the shaft portion 73, the shaft portion 73 can be rotated while suppressing the inclination of the shaft portion 73, and rattling of the shaft portion 73 during rotation of the pin 70 can be suppressed.

When it is desired to remove the second member 5 from the first member 1, the pin 70 is rotated in a predetermined direction to receive the pair of engaging protrusions 75, 75 and the pair of engaging receiving pieces 50, 50. The shaft portion 73 is removed from the portions 51 and 51 so as to be aligned with the pair of protrusion insertion passages 62 and 62 of the second plate portion 30, and then the second member 5 is separated from the first member 1. Is pulled out from the shaft insertion passage 60 of the second plate portion 30, the first mounting hole 2 of the first member 1, and the pin insertion passage 21 of the first plate portion 20, respectively, from the first member 1 to the second member 5. Can be removed.

Further, in this embodiment, the projecting piece 37a is projected toward the engagement receiving piece 50 side at the center of the band-shaped piece connecting portion 37 of the second plate portion 30 in the width direction B, and is the same. Since the projecting piece 38a is projected toward the engagement receiving piece 50 side at the center of the connecting portion 38 of the second plate portion 20 in the width direction B, the clip 10 is painted or heat-treated. At that time, when a plurality of clips 10 are housed and arranged in a bucket or the like, the first plate portion 20 or the like of another clip 10 is prevented from entering the gap of the second plate portion 30 of the predetermined clip 10. As a result, the plurality of clips 10 are less likely to be entangled, so that the productivity of the clips 10 can be increased.

Further, in this embodiment, unlike the conventional clip, the structure is not such that a plate-shaped holding piece is provided inside the pair of elastic strip-shaped pieces via an elongated slit, so that the mold for clip forming can be used. , It is not necessary to provide an elongated punch or the like for forming an elongated slit, and the durability of the mold can be improved (the elongated punch or the like is easily worn or broken). Further, when a plate-shaped holding piece is provided inside the pair of elastic strip-shaped pieces, it is necessary to strictly control the opening dimension between the holding piece and the first plate portion (dimension control is poor). In this clip, a pair of elastic strip-shaped pieces and a pair of elastic strip-shaped pieces are provided inside the pair of elastic strip-shaped pieces. Since it is only necessary to control the opening dimension with the plate portion, product management becomes easy.

The present invention is not limited to the above-described embodiment, and various modified embodiments are possible within the scope of the gist of the present invention, and such embodiments are also included in the scope of the present invention. ..
