3 to 7B show an embodiment of the present invention. A vehicle body panel 1 which is a member to be mounted has a horizontal surface 2 as a first mounting surface and an inclined surface 3 as a second mounting surface inclined with respect to the horizontal plane 2 . That is, the vehicle body panel 1 has mounting surfaces with different surface directions. Mounting holes 4 and 5 are respectively opened on the horizontal plane 2 and the inclined plane 3 .

The protector 10 has: a protector main body 11 having a wire accommodating chamber inside; and a cover 12 that closes an upper surface opening of the protector main body 11 . On the bottom portion of the protector main body 11 , first mounting portions 20 and second mounting portions 30 are provided at two positions corresponding to the respective mounting holes 4 and 5 of the vehicle body panel 1 .

The basic structures of the first mounting part 20 and the second mounting part 30 will be described. The first mounting part 20 and the second mounting part 30 have bases 21, 31 and jigs 23, 33 protruding from the bases 21, 31, respectively. The bases 21 and 31 are in the shape of a square frame. A pair of spring parts 22a, 22b, 32a, 32b protrude from the bottom surfaces 21a, 31a of the bases 21, 31 toward the blade part 25 described below. Each spring part 22a, 22b, 32a, 32b is a cantilever support structure.

Each clamp 23, 33 has: a shaft part 24, 34 protruding from the bottom surface 21a, 31a of the base 21, 31; a pair of blade parts 25, 35 protruding to the side of the shaft part 24, 34; The ribs 26 , 36 protrude from the upper ends of the blades 25 , 35 toward the base 21 , 31 . A pair of relief grooves 24a, 34a that allow elastic deformation of the blade portions 25, 35 are formed on the side surfaces of the shaft portions 24, 34 (see FIGS. 5A and 5B ). Each blade portion 25, 35 is formed in a tapered shape gradually widening from the tip of the shaft portion 24, 34 toward the root. Each blade part 25, 35 can be elastically deformed in the direction which narrows taper shape by the relief groove 24a, 34a. The upper end surfaces of the respective blade portions 25 , 35 are formed as abutting surfaces 25 a , 25 b , 35 a , 35 b that abut against when attached to the vehicle body panel 1 . Each locking rib 26 , 36 extends from the inner peripheral end of the upper end surface of each blade portion 25 , 35 toward the base 21 . Each locking rib 26, 36 is arc-shaped.

Next, specific structural parts of the first mounting portion 20 and the second mounting portion 30 will be described.

The clip 23 of the first mounting part 20 is formed so that the direction perpendicular to the horizontal plane 2 is inserted into the mounting hole 4 (the axial direction of the clip 23 ) F1. Like the clip 23 of the first mounting part 20 , the clip 33 of the second mounting part 30 is also formed in the direction perpendicular to the horizontal plane 2 as the insertion direction (axial direction of the clip 33 ) F1 into the mounting hole 5 . That is, the directions of the shaft portions 24 , 34 of the clips 23 , 33 of the first mounting portion 20 and the second mounting portion 30 are formed in the same direction F1 .

The horizontal direction of the jig 23 and the base 21 of the first mounting portion 20 is a direction in which the vehicle body panel 1 is sandwiched and fitted. On the other hand, in the clip 33 and the base 31 of the second attachment part 30, the inclined direction inclined with respect to the horizontal direction is formed as the direction in which the vehicle body panel 1 is sandwiched and fitted. That is, the directions in which the vehicle body panel 1 is sandwiched and fitted in the first mounting portion 20 and the second mounting portion 30 are set to be different directions, respectively.

In detail, as shown in FIGS. 6A and 6B , the bottom surface 21a of the base 21 of the first mounting portion 20 is formed along the horizontal direction. The bottom surface 21a of the base 21 is formed in the same height on both sides. A pair of spring part 22a, 22b protrudes from the bottom surface 21a of the same height on either side. Moreover, the contact surfaces 25a, 25b of a pair of blade part 25 are also formed in the same height. Thus, the pair of spring parts 22a and 22b abut against the horizontal plane 2 and the abutment surfaces 25a and 25b of the pair of blade parts 25 of the first mounting part 20 abut against the opposite surface of the horizontal plane 2 .

As shown in FIGS. 7A and 7B , the bottom surface 31 a of the base 31 of the second mounting portion 30 is formed in an oblique direction. The bottom surface 31a of the base 31 is formed to be low on the left side and high on the right side. A pair of spring part 32a, 32b protrudes from the bottom surface 31a whose left-right height differs. In addition, the contact surfaces 35a, 35b of the pair of blade parts 35 are formed so that the left side is low and the right side is high. As a result, the pair of spring parts 32a and 32b abut against the inclined surface 3 and the abutting surfaces 35a and 35b of the pair of blade parts 35 of the second mounting part 30 abut against the opposite surface of the inclined surface 3 .

Next, the operation of attaching the protector 10 to the vehicle body panel 1 will be described. As shown in FIG. 3, the positions of the first mounting portion 20 and the second mounting portion 30 of the protector 10 are aligned with the positions of the two mounting holes 4, 5 of the vehicle body panel 1, and the clips 23, 33 are respectively inserted into the Mounting holes 4,5. Accordingly, the pair of blade portions 25 , 35 of each jig 23 , 33 are elastically deformed toward each other so as to allow the pair of blade portions 25 , 35 to be inserted into the mounting holes 4 , 5 . The pair of spring parts 22 and 32 abut against the vehicle body panel 1 while the pair of vane parts 25 and 35 enter the respective mounting holes 4 and 5 . A pair of blade parts 25, 35 overcomes the elastic force of a pair of spring parts 22, 32 and is gradually inserted into the mounting holes 4, 5. When 4 and 5 are pulled out, the pair of blade parts 25 and 35 undergo elastic recovery deformation. Thus, in the first mounting part 20 and the second mounting part 30, the pair of spring parts 22a, 22b, 32a, 32b and the pair of blade parts 25, 35 sandwich the vehicle body panel 1, thereby preventing the installation holes 4, 5 moves in the insertion/removal direction (positioning in the insertion/removal direction). In addition, in the first mounting portion 20 and the second mounting portion 30 , the pair of locking ribs 26 , 36 are press-contacted to the inner peripheral surfaces of the mounting holes 4 , 5 by utilizing the elastic restoring force of the blade portions 25 , 35 . , thereby preventing movement toward each surface direction of the vehicle body panel 1 (positioning in each surface direction). Accordingly, the protector 10 is fitted in a state of sandwiching the vehicle body panel 1 at the positions of the first mounting portion 20 and the second mounting portion 30 . At this point, the installation operation of the protector 10 is completed.

As described above, the direction of insertion of the clips 23 and 33 of the first mounting part 20 and the second mounting part 30 into the mounting holes 4 and 5 is the same as that of one mounting surface (horizontal plane 2 in this embodiment) of the vehicle body panel 1 . The surface directions are matched and set to the same orientation, and the direction in which the clamps 23, 33 and the bases 21, 31 of the first mounting part 20 and the second mounting part 30 sandwich the vehicle body panel 1 is consistent with the mounting surface, that is, the horizontal plane. The respective surface directions of the 2 and the inclined surface 3 are set in different orientations in accordance with each other.

In the protector 10, since the insertion directions F1 of the clips 23, 33 of the first mounting part 20 and the second mounting part 30 are the same, the clips 23, 33 can be smoothly inserted into the mounting holes 4, 5, and the insertion operability is improved. good. Since the clamps 23, 33 and the bases 21, 31 of the first mounting part 20 and the second mounting part 30 form the surface directions of the mounting surfaces, that is, the horizontal surface 2 and the inclined surface 3, so that the vehicle body panel 1 is sandwiched and fitted. direction, so it can be installed in a firm fitting state.

The protector main body 11 is manufactured by injection molding using a mold. As shown in FIG. 3, since the insertion direction F1 of the clip 23 of the first mounting part 20 and the insertion direction F1 of the clip 33 of the second mounting part 30, that is, the axial directions of the clips 23 and 33 are the same, the first mounting part can 20 and the second mounting part 30 have the same demolding direction, so that the common use of the mold can be realized, and thus the cost of the mold can be suppressed compared with the conventional one. That is to say, in the conventional example, as shown in FIG. Since the axial direction (F2) of the jig 71 is different, the demolding directions of the first mounting part 61 and the second mounting part 62 cannot be the same, and thus different molds are required, and the cost of the molds increases.

In the above-described embodiment, although the attached member is the vehicle body panel 1 , the present invention is applicable even if the attached member is a member other than the vehicle body panel 1 .

In the above-mentioned embodiment, although the installation surfaces with different surface directions of the vehicle body panel 1 are the horizontal surface 2 as the first installation surface and the inclined surface 3 as the second installation surface inclined relative to the first installation surface, the present invention also It can be applied to the case where both are inclined surfaces. In this case, the insertion direction (the axial direction of the clips 23, 33) of the clips 23, 33 of the mounting parts 20, 30 into the mounting holes 4, 5 is set so as to match the surface direction of any one of the inclined surfaces. same orientation.

In the above-mentioned embodiment, although the body panel 1 has two mounting surfaces with different surface directions, the present invention is applicable even if there are three or more mounting surfaces with different surface directions.

In the above-mentioned embodiment, although the mounting part of the protector 10 is two parts of the 1st mounting part 20 and the 2nd mounting part 30, even if it is three or more mounting parts, this invention is applicable.

In the above-mentioned embodiment, although the base 21, 31 has a pair of spring parts 22a, 22b, 32a, 32b, the jig 23, 33 consists of the shaft part 24, 34, a pair of blade parts 25, 35 and a pair of locking ribs. 26 and 36, but any structure can be used as long as the vehicle body panel 1 can be sandwiched and fitted.

The present invention is not limited to the above-described embodiments, and can be implemented by changing constituent elements within a range not exceeding the gist. In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments.
