(Explanation of component mounting method to mounted member)
Hereinafter, a method for attaching a component to a member to be attached using the resin clip 100 for attaching a component of the present invention will be described with reference to FIG. In FIG. 3, 300 is a member to be attached such as an under cover, and 400 is a component such as a deflector attached to the member to be attached. In FIG. 3, the attached member 300 and the component 400 make the cross section in the thickness direction visible for convenience. As shown in FIG. 3A, rectangular fitting holes 300 a and 400 a are formed in the attached member 300 and the component 400. The width dimension of the clamping piece 12 and the connection piece 13 is slightly smaller than the width dimension of the insertion holes 300a and 400a. Circular mounting holes 300b and 400b are formed at positions adjacent to the insertion holes 300a and 400a of the mounted member 300 and the part 400. The shapes of the insertion hole 300a and the insertion hole 400a are the same. Further, the inner diameters of the mounting hole 300b and the mounting hole 400b are the same. Furthermore, the positional relationship between the insertion hole 300a and the mounting hole 300b and the positional relationship between the insertion hole 400a and the mounting hole 400b are the same. A protruding positioning portion 400c is formed on the surface of the component 400 opposite to the surface in contact with the mounted member 300.

  As shown in FIG. 3A, the part 400 is overlapped on the member to be attached 300 so that the insertion hole 300a and the insertion hole 400a are aligned with each other. Next, as shown in FIG. 3B, the clamping piece 12 is inserted into the insertion holes 300 a and 400 a, and the attachment member 300 and the component 400 are clamped by the substrate 11 and the clamping piece 12. In addition, since the jumping part 12b is formed in the front-end | tip of the clamping piece 12, and it has the shape which the front-end | tip of the board | substrate 11 and the clamping piece 12 expanded, it is easy to insert the clamping piece 12 in the insertion holes 300a and 400a. . When the clamping piece 12 is inserted all the way into the insertion holes 300a and 400a, the positioning part 400c engages with the positioning part 11b. When the clamping piece 12 is inserted all the way into the insertion holes 300a and 400a and the connection piece 13 is in contact with the peripheral edge of the insertion holes 300a and 400a, the locking holes 11a and 12a and the mounting holes 300b and 400b are coaxially matched. ing. In this state, since the positioning portion 400c is engaged with the positioning portion 11b, the position of the component 400 in the front-rear direction with respect to the attached member 300 is not displaced, and the connection piece 13 is inserted through the insertion holes 300a and 400a. Since the parts 400 are in contact with each other, the position of the part 400 in the width direction with respect to the attached member 300 is not displaced, and the part 400 is attached to the attached member 300 in a state where the locking holes 11a and 12a and the attaching holes 300b and 400b are coaxially matched. And temporarily fixed.

  Next, the connecting portion 30 is bent at the bending groove 30a, and the locking piece 23 is inserted into the first locking hole 11a, the mounting holes 300b and 400b, and the second locking hole 12a. At this time, the bent groove 30a is broken. When the locking portions 23b pass through the second locking holes 12a, the locking portions 23b are expanded, the locking pieces 23 are locked in the second locking holes 12a, and the component 400 is attached to the attached member 300. Attached to. In this state, the flange portion 22 is pressed against the substrate 11 to be deformed, and the reaction force of the flange portion 22 is applied to the locking piece 23. For this reason, the mounted member 300 and the component 400 sandwiched between the sandwiching piece 13 and the substrate 11 are compressed and sandwiched between the locking surface 23c of the locking piece 23 and the flange portion 22 and attached to the mounted member 300. The rattling of the part 400 is prevented. The locking hole 11 a is closed by the flange portion 22, and the insertion hole 400 a is closed by the substrate 11.

Thus, in the present invention, the sandwiching piece 12 is inserted into the insertion holes 300a and 400a, the connecting portion 30 is bent at the bending groove 30a, and the locking piece 23 is attached to the first locking hole 11a, the mounting hole 300b, The component 400 can be attached to the attached member 300 while being temporarily fixed by a simple operation of inserting it into the second locking hole 12a.
Note that when the attached member 300 is an undercover and the attached member 300 is a deflector, the bent groove 30a is broken at the time of attachment. Is not caught. Moreover, since the flange part 22 has obstruct | occluded the 1st locking hole 11a, foreign materials, such as rain water, do not approach into the to-be-attached member 300 which is an undercover.

  In the present invention, since the temporary fixing portion 10 and the attachment portion 20 are connected by the connection portion 30, it is not necessary for the operator to take separate parts from the respective component boxes, and the workability is good. Since the bent groove 30 a is formed in 30, the operator can clearly grasp the position where the connecting portion 30 is bent.
