It is explanatory drawing of the fixing method of the bracket which concerns on this embodiment, (A) is a temporary fixing process, (B) is a moving process, (C) is a final tightening process, (D) shows piping fixing process.

The bracket according to the present embodiment will be described below based on the attached drawings. The same parts are given the same reference numerals, and their names and functions are also the same. Therefore, detailed description about them will not be repeated.
(Configuration of bracket 10 according to the present embodiment)
FIG. 1 is a view showing a bracket in the present embodiment, in which (A) is a plan view and (B) is a cross-sectional view taken along the line II.

  The bracket 10 has a main body 11 having a rectangular cross section and extending in a predetermined direction. A long hole 12 is formed at one end in the longitudinal direction of the main body 11, and a round hole 13 as a fixing portion is formed at the other end in the longitudinal direction.

  The elongated hole 12 is formed to be inclined at a predetermined angle with respect to the longitudinal direction of the main body 11. Further, the arrangement of the bracket 10 as shown in FIG. 1A (ie, the longitudinal direction of the main body 11 is parallel to the vertical direction, the long hole 12 is at the upper part in the vertical direction, and the round hole 13 is in the vertical direction In the lower portion of the long hole 12, the elongated hole 12 is formed to be inclined so as to approach the anti-rotation rib 22 described later as it goes downward in the longitudinal direction of the main body 11. The angle of inclination is 45 ° as shown in FIG. 1A as an example.

  Further, a bolt 15 is inserted into the long hole 12.

  The round hole 13 is for attaching a clip 30 for holding the piping 31 as an object to be fixed. On the back surface side of the main body 11, a welding nut (not shown) to be screwed with an external thread inserted into the round hole 13 is provided.

  The bracket 10 is attached to the mounting member. Examples of the mounting member include, but are not limited to, the side surface of the engine, and more specifically, the pedestal portion 21 formed by raising a part of the intake manifold 20, but is not limited thereto. Further, the pedestal portion 21 is provided with a rotation preventing rib 22 as a projection portion for preventing the rotation of the bracket 10. The rotation preventing rib 22 is, for example, expanded from a part of the pedestal portion 21 and integrally formed with the pedestal portion 21, but may be formed separately from the pedestal portion 21. Also, the rotation preventing rib 22 extends in the vertical direction. Further, in the vicinity of the center of the pedestal portion 21, a female screw 23 to be screwed with the male screw of the bolt 15 is formed.

  The bracket 10 is disposed such that the longitudinal direction of the main body 11 is parallel to the vertical direction. The main body 11 is fixed by screwing the male screw of the bolt 15 inserted into the long hole 12 with the female screw 23.

Next, before describing the operation and effects of the bracket 10 according to the present embodiment, the configuration of the comparative example as a premise and the problems thereof will be described.
(Configuration of Bracket 50 of Comparative Example and Problems Thereof)
FIG. 2 is an explanatory view of a bracket of a comparative example, in which (A) shows a state of alignment and (B) shows a state of fastening with a bolt.

  The bracket 50 is formed similarly to the bracket 10 shown in FIG. 1 except that a round hole 52 is formed at one end in the longitudinal direction of the main body 51 extending in a predetermined direction and having a rectangular cross section.

  The bracket 50 is fixed to the pedestal portion 21 formed in the intake manifold 20 at a single point by the bolt 15 inserted into the round hole 52 in the same manner as the bracket 10.

  Here, since the rotation preventing rib 22 is formed as a projection on the pedestal portion 21, when the bracket 50 is originally disposed at a position adjacent to the rotation preventing rib 22, when the bracket 15 is fastened by the bolt 15, The side surface and the protrusion side surface of the rotation preventing rib 22 contact with each other, and the rotation of the bracket 50 is prevented.

  However, the position of the female screw 23 provided on the pedestal 21 may vary due to a manufacturing error or the like, which may cause positional deviation. For example, as shown in FIG. 2A, when the bracket 50 is positioned on the pedestal 21, a clearance C may be generated between the bracket 50 and the rotation preventing rib 22. When the bracket 50 is fastened with the bolt 15 in this state, as shown in FIG. 2B, the main body 51 contacts the lower end of the rotation preventing rib 22 with the position of the round hole 52 (female screw 23) as a fulcrum. It will rotate clockwise.

Even if the width of the clearance C is slight, at the position of the round hole 13 at a certain distance from the position of the round hole 52 (female screw 23), the horizontal deviation is several times or more by "lever principle". To expand. Therefore, when the clip 30 is attached to the round hole 13, the horizontal position of the clip 30 may be largely displaced, and the piping 31 may not be attached.
(A method of fixing the bracket 10 according to the present embodiment)
Next, a method of fixing the bracket 10 according to the present embodiment will be described based on FIG.

First, as shown in FIG. 3A, the bracket 10 is disposed on the pedestal 21 and the bolt 15 is inserted into the long hole 12 to perform temporary fastening (temporary fastening process).
For temporary fixing, the bolt 15 is lightly rotated a couple of times, and the external thread of the bolt 15 is shallowly screwed on the female screw 23.

  A clearance C is assumed to be provided between the bracket 10 and the rotation preventing rib 22 as in FIG.

  Next, as shown in FIG. 3B, the bracket 10 is on the side of the rotation preventing rib 22 while keeping the longitudinal direction of the main body 11 parallel to the vertical direction along the inclination direction of the long hole 12 by the weight of the bracket 10. Move to As a result of the movement, the main body 11 contacts the rotation preventing rib 22 (moving step).

  Next, as shown in FIG. 3C, the bolt 15 is further rotated, and the male screw of the bolt 15 is completely screwed with the female screw 23 to fix the bracket 10 on the pedestal 21 (final tightening Process).

Finally, as shown in FIG. 3D, the clip 30 is attached to the bracket 10 by inserting and fastening the clip fixing bolt 40 into the round hole 13 while bundling the pipes 31 with the clip 30 (pipes Fixing process).
(Effect of this embodiment)
In the bracket 10 according to the present embodiment, even if the clearance C is generated between the rotation preventing rib 22 due to the positional deviation of the female screw 23 when temporarily fixed to the pedestal portion 21, the bracket 10 Due to its own weight, the bracket 10 moves to the rotation preventing rib 22 side and contacts while keeping the longitudinal direction of the main body 11 parallel to the vertical direction along the inclination direction of the long hole 12. Therefore, even if the bracket 10 is fastened by the bolt 15, the main body 11 does not rotate, and it is possible to prevent the position of the clip 30 from being shifted in the horizontal direction. Therefore, the pipe 31 can be reliably fixed by the clip 30 without affecting the attachment of the pipe 31 extending in the vertical direction.

  The present invention is not limited to the embodiments described above, and can be appropriately modified and implemented without departing from the spirit of the present invention.

  For example, in the present embodiment, the inclination angle of the elongated hole 12 with respect to the longitudinal direction of the main body 11 is 45 °, but if it is other than 0 ° (parallel to the longitudinal direction) and 90 ° (perpendicular to the longitudinal direction) It can be suitably set within the range in which movement by the weight of 10 is possible.

  Moreover, in this embodiment, when performing temporary fastening of the bracket 10, although the same volt | bolt 15 as full fastening was used, you may use another bolt for temporary fastening only.

  Further, in the present embodiment, an example of the pedestal portion 21 formed in a part of the intake manifold 20 is shown as the mounting member of the bracket 10, but the bracket 10 can be moved by its own weight at the time of temporary fastening. It may be a cylinder block, a vehicle body frame or the like. Furthermore, although the example of piping was shown as a fixed subject in this embodiment, wiring members, such as a wire harness, may be used.
