FIG. 6 is a cross-sectional view taken along line AA of the clip 10 shown in FIG. As shown in FIG. 6, the restricting portion 46 is accommodated in the engaging portion 56 in a state where the restricting portion 46 is close to the edge of the engaging portion 56. Accordingly, the leaf spring member 22 is restricted from moving in the width direction of the leaf spring member 22 and moving in the direction from the base end side toward the free end side.

The first connecting part 52 and the second connecting part 30 are provided so as to overlap each other, and the elastic part 38 on the second connecting part 30 side is in contact with the first connecting part 52. The elastic part 38 is formed so as to protrude to the free end side. The elastic part 38 urges the first connecting part 52 in the direction of separating.

FIG. 7 is a sectional view taken along line BB of the clip 10 shown in FIG. The leaf spring member 22 is urged toward the free end by the elastic portion 38, and the free end of the plate-like portion 50 comes into contact with the inner surfaces of the free end portion 32 a and the free end portion 34 a of the holding member 20. The pair of plate-like parts 50 are restricted from moving away from the first wall part 32 or the second wall part 34 by the free end part 32a and the free end part 34a. Thereby, rattling of the holding member 20 and the leaf spring member 22 can be suppressed, and rattling of the mounting member in a state where the clip 10 is mounted on the mounted member can be suppressed.

FIG. 8 is an exploded view of the clip 10. FIG. 9 shows the clip 10 during assembly. The assembly process of the clip 10 will be described. As shown in FIG. 8, the leaf spring member 22 is assembled from the side rather than from the free end side of the holding member 20.

The distance L1 from the inner surface of the second connecting portion 30 to the inner surface of the free end portion 32a shown in FIG. 3A, that is, the total length L1 of the spring accommodating space of the holding member 20 is a leaf spring member shown in FIG. It is longer than the total length L2 of 22. The total length L2 of the leaf spring member 22 is the length from the first connecting portion 52 to the free end of the plate-like portion 50. Thereby, since there is a gap when the leaf spring member 22 is inserted to the side of the holding member 20, it can be easily inserted. Further, since the elastic portion 38 extends in the width direction, it is easier to insert the leaf spring member 22 than when the elastic portion 38 extends in the opposing direction.

When the leaf spring member 22 is inserted from the side of the holding member 20, the first connecting portion 52 of the leaf spring member 22 hits the elastic portion 38 of the holding member 20. The first connecting portion 52 pushes the tapered surface 38 a of the elastic portion 38 and bends the elastic portion 38 and the connecting portion 40 interlocked with the elastic portion 38.

As shown in FIG. 9B, the plate-like portion 50 gets over the restricting portion 46, and the restricting portion 46 is disposed in the engaging portion 56. At this time, due to the pushing of the elastic portion 38 of the first connecting portion 52, the elastic portion 38 bends outward, and in conjunction with this, the connecting portion 40 and the restricting portion 46 are displaced so as to be lowered outward, It becomes easy for the plate-like part 50 to get over the restricting part 46. This is because the elastic portion 38 is separated from the first wall portion 32 side by the first slit 42, and is connected to the second wall portion 34 side by the connecting portion 40, and thus is pulled to the second wall portion 34 side. It is. Thus, the elastic portion 38 acts to lower the regulating portion 46 outward when the leaf spring member 22 is assembled, and after the assembly, the leaf spring member 22 is urged to suppress rattling.

The height at which the elastic portion 38 protrudes from the inner surface of the second connecting portion 30 is greater than the difference between the full length L1 and the full length L2. Thereby, the elastic part 38 can urge the leaf spring member 22 to press the free end of the leaf spring member 22 against the free end portion 32a and the free end portion 34a.

FIG. 10 is a perspective view of the clip 100 of the first modified example. The clip 100 of the first modified example is the same as the clip 10 shown in FIG. 1 in that the holding member 120 and the leaf spring member 22 are the same, but the direction when the leaf spring member 22 is assembled to the holding member 120 is the same. Different. In the first modification, the leaf spring member 22 is inserted from the free end sides of the first wall portion 132 and the second wall portion 134.

FIG. 11 is a perspective view of the holding member 120 of the first modification. The second connecting part 130 connects the first wall part 132 and the second wall part 134. The 2nd connection part 130 has the elastic part 138 extended in an opposing direction. The elastic portion 138 protrudes from the other second connecting portion 130 toward the free end, and biases the assembled plate spring member 22 toward the free end. A pair of slits 142 extending in opposite directions are formed on both sides of the second connecting part 130.

The free end portion 132a of the first wall portion 132 and the free end portion 134a of the second wall portion 134 are bent so as to be folded inward. Thereby, it can suppress that the assembled | attached leaf | plate spring member 22 remove | deviates to a free end side.

A protrusion 132b and a protrusion 134b are formed at the center of the inner surfaces of the free end 32a and the free end 34a, respectively, and restrict the movement of the plate spring member 22 in the width direction as an engagement with the plate spring member 22. The restricting portion 146 is formed to protrude from the inner surfaces of the first wall portion 132 and the second wall portion 134, respectively.

FIG. 12 is a sectional view taken along line CC of the clip 100 of the first modification shown in FIG. The elastic portion 138 of the holding member 20 biases the first connecting portion 52 of the leaf spring member 22 to the free end side. The free end of the leaf spring member 22 stops by coming into contact with the free end portion 132a and the free end portion 134a projecting inward in the opposite direction by the biasing of the elastic portion 138. Thereby, rattling of the leaf spring member 22 and the holding member 120 can be suppressed.

FIG. 13 is an exploded view of the clip 100 of the first modification. The leaf spring member 22 is inserted between the free end portion 132a and the free end portion 134a of the holding member 120, and is pushed in while expanding the first wall portion 132 and the second wall portion 134. The engaging portion 56 receives the restricting portion 146, and the concave portion 58 receives the protrusion 132b and the protrusion 134b, and the assembly is completed.

In the clip 100 of the first modified example, the elastic portion 138 urges the first connecting portion 52 of the leaf spring member 22, so that the play between the leaf spring member 22 and the holding member 120 can be suppressed.

FIG. 14 is a perspective view of the clip 200 of the second modified example. The clip 200 of the second modified example is different from the clip 10 shown in FIG. 6 in that the elastic portion 54 is provided on the leaf spring member 222.

The first connecting portion 52 of the leaf spring member 222 is formed in a flat plate shape. The 1st connection part 52 has a pair of elastic part 54 extended in the width direction. The pair of elastic portions 54 are cantilever pieces extending in a direction approaching each other.

The holding member 220 has a second connecting part 230 that connects the base end sides of the first wall part 232 and the second wall part 234, and the second connecting part 230 has a protrusion 230a on the inner surface in the center. The protrusion 230a contacts the pair of elastic portions 54 and receives a biasing force. As a result, the leaf spring member 222 receives a reaction force on the free end side and hits the free end portion 232a and the free end portion 234a, thereby suppressing rattling.

FIG. 15 is a perspective view of the clip 200 of the second modified example shown in FIG. The protrusion 230 a has a tapered portion 247 formed on the base side and a regulating portion 246 formed on the tip side from the tapered portion 247.

The pair of tapered portions 247 are inclined so as to rise toward the tip of the protruding portion 230a along the width direction. The restricting portion 246 is bent from the tapered portion 247 and is inclined more steeply than the tapered portion 247. The restricting portion 246 is formed substantially perpendicular to the second connecting portion 230.

The taper part 247 pushes the elastic part 54 of the leaf spring member 22 to the free end side. The restricting portion 246 hits both ends of the elastic portion 54 and restricts the movement of the leaf spring member 22 in the width direction. Thus, the protrusion 230a pushes the leaf spring member 22 to the free end side and restricts the movement of the leaf spring member 22 in the width direction.

FIG. 16 is an exploded view of the clip 200 of the second modified example. The leaf spring member 222 is inserted along the width direction from the side of the holding member 220.

The protrusion 230a is formed in a prismatic shape and has a tapered surface inclined so as to rise to the free end side in the width direction. The taper surface of the protrusion 230a serves as a guide when the leaf spring member 222 is assembled, and facilitates the pushing of the leaf spring member 222.

In the clip 200 of the second modified example, the elastic portion 54 is provided on the leaf spring member 222, so that a decrease in the rigidity of the holding member 220 can be suppressed.

FIG. 17 is an exploded view of the clip 300 of the third modified example. The clip 300 of the third modification is different from the clip 200 shown in FIG. 16 in the shape of the protrusion 330 a of the holding member 320 and the shape of the elastic portion 354 of the leaf spring member 322.

The protruding portion 330a is formed at the center of the inner surface of the second connecting portion 30, and is formed so as to protrude in a substantially hemispherical shape. It is possible to easily push in the leaf spring member 322 by curving the protruding portion 330a.

The pair of elastic portions 354 are formed in the first connecting portion 52 and extend so as to approach each other along the width direction. The ends of the pair of elastic portions 354 are formed so as to be cut out in an arc shape, and engage with the protrusions 330a. Thereby, rattling between the leaf spring member 322 and the holding member 320 can be suppressed.

18 is a cross-sectional view taken along line EE of the clip 300 shown in FIG. A line segment EE shown in FIG. 17 indicates a cross-sectional position of the holding member 320, but FIG. 18 also shows a plate spring member 322 in addition to the holding member 320.

The protrusion 330a pushes the leaf spring member 22 to the free end side by contact with the elastic portion 354 and restricts the movement of the leaf spring member 22 in the width direction. The pair of arc portions 355 are formed by being cut out so as to be recessed in the first connecting portion 52, and engage with the peripheral surface of the protruding portion 330a. The movement of the leaf spring member 22 in the width direction can be restricted by the engagement of the arc portion 355 and the projection portion 330a. As described above, by fitting the elastic portion 354 and the arc portion 355 to the protruding portion 330a, the play between the leaf spring member 322 and the holding member 320 can be suppressed.
