Description

Steering member

This case concerns steering members.

In vehicles such as automobiles, an instrument panel is installed in the front of the passenger compartment. A steering member is provided as a strength member inside the instrument panel.

In this steering member, side brackets that can be fixed to a vehicle body are attached to both ends of a member main body extending in the vehicle width direction (see, for example, Patent Document 1).

JP 2014-28550 A

However, the steering member described in Patent Document 1 has the following problems.

That is, an airbag device is attached to the member body. The force applied to the member main body when the airbag device is activated is transmitted to the side bracket as a torsional force. Therefore, in order to receive the torsional force, the member body has a large cross-section (or diameter) to ensure the rigidity of the member body, or the side bracket is thickened to increase the rigidity of the side bracket. It was necessary to raise. Therefore, the steering member has increased in weight and cost.

Therefore, the main purpose of this case is to solve the above-mentioned problems.

In order to solve the above problem,
Side brackets that can be fixed to the vehicle body are attached to both ends of the member body that extends in the vehicle width direction.
The side bracket has a front-rear direction fixing portion that can be fixed to the vehicle body in the front-rear direction,
The front-rear direction fixing portion is characterized by a steering member constituting a hollow body having a space portion extending vertically.

According to this case, the above-described configuration can reduce the weight and cost of the steering member.

It is a whole perspective view of the steering member concerning this embodiment. It is the expansion perspective view of the side bracket part which looked at FIG. 1 from the vehicle body diagonally rear side. FIG. 3 is a transverse sectional view taken along line XX of the side bracket of FIG. 2. It is explanatory drawing (figure which looked at the instrument panel part from the side) which shows the attachment position of the steering column with respect to a steering member. It is a partial expansion perspective view of the vehicle body which attaches a steering member. It is the cross-sectional view which expanded the side bracket part which shows the attachment state of the steering member with respect to a vehicle body. It is an expansion perspective view of the side bracket part similar to FIG. 2 concerning a modification. FIG. 8 is a cross-sectional view taken along line YY of the side bracket of FIG.

Hereinafter, the present embodiment will be described in detail with reference to the drawings.

FIG. 1 to FIG. 8 are for explaining this embodiment and its modifications.

<Configuration> The configuration of this embodiment will be described below.

For vehicles such as automobiles, an instrument panel is installed at the front of the passenger compartment. A steering member is provided as a strength member inside the instrument panel. The steering member is for connecting the left and right vehicle body panels and supporting the steering column.

As shown in FIG. 1 (FIG. 3), the steering member 1 has side brackets that can be fixed to the vehicle body (see the vehicle body panel 4 in FIG. 5) at both ends of the member main body 3 extending in the vehicle width direction 2. 5 is provided.

The side bracket 5 has a front-rear direction fixing portion 7 that can be fixed to the vehicle body in the front-rear direction 6 of the vehicle.

Here, the member main body 3 is a metal cylinder or the like. In this case, as for the member main body 3, the driver seat side part is made into the large diameter part 3a, and the passenger seat side part is made into the small diameter part 3b. However, the member main body 3 may have a constant diameter dimension over the entire length. A column bracket 12 is installed on the driver seat side portion of the member main body 3. The column bracket 12 is for attaching a steering column 21 (see FIG. 4). Furthermore, one or a plurality of post brackets 14 are installed on the front side of the member main body 3 in the vehicle front-rear direction 6. This post bracket 14 is for attaching the steering member 1 to the vehicle compartment front wall 13 (see FIG. 5).

Also, a stay 16 is provided in the middle part of the member main body 3. The stay 16 can support and fix the member main body 3 to the floor panel. The stay 16 is a rod-shaped metal member or the like extending substantially in the vertical direction 17. In this case, two stays 16 are provided for the driver seat side and the passenger seat side. For example, only one stay 16 may be provided on the driver's seat side. The stay 16 has a C-shaped cross section. In addition, an auxiliary bracket etc. can be used for the attachment part with respect to the floor panel of the stay 16 as needed.

At this time, as shown in FIG. 4, the steering member 1 is positioned above the center of gravity 22 of the steering column 21 or in the vicinity thereof.

Here, the position of the center of gravity 22 of the steering column 21 is the position of the center of gravity 22 in the portion of the steering column 21 located in the vehicle interior.

The portion of the steering column 21 located in the vehicle compartment is a portion on the rear side of the connection portion of the steering column 21 to the portion on the engine room side. More specifically, it is a portion between the steering wheel and the intermediate shaft (that is, between the steering wheel and the first universal joint located forward of the vehicle). The steering column 21 includes a steering wheel. In the case of the steering-by-wire system, since the intermediate shaft is not used, only the portion located in the vehicle interior is provided.

When the steering member 1 is positioned above the gravity center 22 of the steering column 21 or in the vicinity thereof, when a straight line extending vertically upward (up and down direction 17) from the position of the gravity center 22 of the steering column 21 is assumed, A straight line indicates that the cross section 23 of the member main body 3 exists. In the present embodiment, the center of gravity 22 or the straight line is within the range 23 from the frontmost part to the rearmost part of the diameter of the pipe constituting the member main body 3 extending in the vehicle front-rear direction 6.

Then, by installing the steering member 1 on the upper side of the center of gravity 22 of the steering column 21, the steering member 1 is located on the vehicle rear side from the general front position as indicated by the phantom line inside the instrument panel 24. It is displaced backward to a rearward position close to the meter 25.

Therefore, as shown in FIGS. 5 and 6 (mainly refer to FIG. 6), the side bracket 5 of the steering member 1 is not on the side wall 31 of the left and right body panels 4 but on the left and right body panels 4 (rear of the vehicle). It is fixed with bolts 33 in the vehicle front-rear direction 6 with respect to the opening flange 32 of the door (located on the side) (such as a mounting seat 32a provided on the door). For fixing the side bracket 5 to the door opening flange 32 in the vehicle front-rear direction 6, it is preferable to use a general tool 34 as shown in FIG. 6 instead of a dedicated tool.

As described above, the moment applied to the steering member 1 by the vibration of the steering column 21 can be minimized by positioning the steering member 1 above the gravity center 22 of the steering column 21 or the vicinity thereof. Therefore, it is possible to reduce the weight of the steering member 1 by reducing the section modulus of the steering member 1.

At this time, as described above, the steering member 1 may be a continuous body having a round cross section and extending straight with a constant diameter over the entire length. In this way, stress concentration on the steering member 1 due to vibration input is reduced, so that the steering member 1 can be further reduced in weight.

In contrast to the basic configuration as described above, this embodiment has the following configuration.

(1) As shown in FIGS. 2 and 3, the front-rear direction fixing portion 7 is configured as a hollow body having a space portion 41 extending vertically.

Here, the vertically extending space 41 is provided for the front-rear direction fixing portion 7 in order to increase the rigidity of the steering member 1. In particular, the vertically extending space 41 receives a torsional force 45 applied to the member main body 3 in accordance with the operation of the airbag device (attached to the member main body 3) (or by the torsional force 45). It is preferable that the rigidity can be increased so that deformation can be prevented. Since the member main body 3 tries to rotate (or axially rotate) about the axis 46 by the torsional force 45, the space portion 41 extending up and down of the front-rear direction fixing portion 7 moves the axis 46 of the member main body 3. The rotation around the center can be stopped. The torsional force 45 applied to the member body 3 is generated in the opposite direction when the airbag device is activated and when a reaction force is generated after the operation. In order to stop such rotation in both directions, the space portion 41 extending vertically is provided so as to cover at least the entire end surface of the member main body 3. In this case, the front-rear direction fixing portion 7 is a cavity having a substantially closed cross section when viewed from above. Alternatively, the space 41 extending vertically is a gap that penetrates substantially in the vertical direction 17.

At this time, the space 41 extending vertically is preferably substantially triangular or L-shaped in plan view, as will be described later.

The vertically extending space portion 41 having a substantially triangular shape or substantially L shape in plan view has a lateral side portion extending in the vehicle width direction 2 on the front side, and a vertical length extending in the vehicle front-rear direction 6 on the end side of the member main body 3. It is preferable to have a side portion.

The space portion 41 extending vertically may be provided by the front-rear direction fixing portion 7 alone. Or you may make it provide the space part 41 extended up and down between the auxiliary | assistant components attached integrally to the front-back direction fixing | fixed part 7 and the front-back direction fixing | fixed part 7 so that it may mention later. In addition, the space part 41 extended up and down is provided with the side bracket 5 (front-rear direction fixing part 7) as a state before the front-rear direction fixing part 7 is attached to the mounting seat part 32a of the opening flange 32. It is a hollow structure, and is different from, for example, a configuration in which a space is formed between the mounting seat 32a of the opening flange 32 after the mounting to the vehicle body.

(2) The front-rear direction fixing portion 7 includes at least a member fixing surface 51 fixed to the member main body 3 and a vehicle body that is bent from the member fixing surface 51 and can be abutted and fixed to the vehicle body in the vehicle front-rear direction 6. A contact fixing surface 52 may be provided.

Further, a reinforcing portion 53 that constitutes a space portion 41 that extends vertically may be provided between the member fixing surface 51 and the vehicle body contact fixing surface 52.

Here, the front-rear direction fixing portion 7 is a metal member (bracket main body) provided so that at least the member fixing surface 51 and the vehicle body abutting fixing surface 52 are substantially L-shaped in plan view. The member fixing surface 51 has a surface that extends substantially in the vehicle front-rear direction 6 and the vertical direction 17. The member fixing surface 51 is provided with a burring hole-like protruding portion 51a capable of fitting and fixing the end portion of the member main body 3 inward. Further, the vehicle body abutment fixing surface 52 has a surface 52 a that extends substantially in the vehicle width direction 2 and substantially in the vertical direction 17. Under the surface 52a, for example, an inclined surface 52b, a stepped surface 52c, or the like may be appropriately provided in accordance with the shape of the mounting seat portion 32a around the opening flange 32. The vehicle body contact fixing surface 52 is located on the front side of the member fixing surface 51, and a rounded bent portion 55 is provided between the member fixing surface 51 and the vehicle body contact fixing surface 52. A mounting hole 56 for fixing to the vehicle body with a fastening member such as a bolt 33, a positioning hole for positioning, and the like are appropriately provided on the vehicle body contact fixing surface 52. The attachment holes 56 are respectively provided on the upper side and the lower side at least with respect to the axis 46 of the member main body 3.

Further, a bent edge 57 is integrally provided on the opposite side of the vehicle body contact fixing surface 52 from the member fixing surface 51. In this case, the bent edge portion 57 is substantially parallel to the member fixing surface 51 and is shorter than the member fixing surface 51 and extends substantially rearward of the vehicle. The bent edge 57 is not exposed to the end of the member main body 3 or the end of the member main body 3 when the steering member 1 is viewed from the side before the reinforcing portion 53 is attached. It is said to be long.

Further, the reinforcing portion 53 is constituted by a metal member (space forming member) that is separate from the front-rear direction fixing portion 7. The reinforcing portion 53 is stretched between the edge portion of the member fixing surface 51 in the front-rear direction fixing portion 7 on the vehicle rear side and the outer end portion of the vehicle body contact fixing surface 52 or the bent edge portion 57. A space 41 extending vertically is formed between the front-rear direction fixing portion 7 and the bending angle between the front-rear direction fixing portion 7 and the vehicle body contact fixing surface 52 is restricted. The reinforcing portion 53 is fixed to the front-rear direction fixing portion 7 by welding or the like, so that the side bracket 5 is configured integrally with the front-rear direction fixing portion 7. In order to configure the space 41 extending vertically, the reinforcing portion 53 has a shape that is at least partially separated from the front-rear direction fixing portion 7. In this case, the space portion 41 extending vertically is substantially the same length as the length of the reinforcing portion 53 in the vertical direction 17.

(3) And the reinforcement part 53 shall cover the edge part of the member main body 3 made into the cylinder shape. The reinforcing portion 53 may have a through hole 61 that communicates with the inside of the member main body 3.

Here, the reinforcing portion 53 covers at least the end portion (the whole) of the cylindrical member main body 3 from the side via the space portion 41 extending vertically, and the member of the front-rear direction fixing portion 7. A first flat surface portion 62 extending along the fixing surface 51 and a second flat surface portion 64 extending from the first flat surface portion 62 toward the vehicle body contact fixing surface 52 of the front-rear direction fixing portion 7 are provided. Is preferred. Alternatively, the reinforcing portion 53 includes the first flat surface portion 62 described above, and the curved surface portion 63 and the second curved surface portion 63 extending from the first flat surface portion 62 substantially along the bent portion 55 of the front-rear direction fixing portion 7 and the vehicle body contact fixing surface 52. A flat surface portion 64 may be provided.

The first flat surface portion 62, the curved surface portion 63, and the second flat surface portion 64 are configured by a flat surface or a curved surface that extends in the up-down direction 17. As a result, the vertically extending space portion 41 formed between the front-rear direction fixing portion 7 and the reinforcing portion 53 has a substantially triangular shape or a substantially L shape in plan view. The space portion 41 that is substantially L-shaped in a plan view and extends in the vertical direction extends in the vertical direction 17 more than the position of the uppermost portion or the lowermost portion in the diameter direction of the member main body 3. That is, the vertically extending space 41 is longer in the vertical direction 17 than the diameter of the member body 3.

The above-described through hole 61 is provided for the first flat surface portion 62 and the curved surface portion 63. The second flat surface portion 64 is provided with a working hole 65 for passing the bolt 33, the tool 34, and the like at a position that matches the mounting hole 56.

The second flat surface portion 64 is, as viewed from above, most or all of the second flat surface portion 64 is located on the front side of the axis 46 of the member main body 3 and is inclined obliquely toward the position of the axis 46 or the rear side thereof. The extending inclined surface is preferable. In FIG. 3, the extension line on the rear surface of the second flat surface portion 64 is directed to the position of the axis 46 of the member main body 3, but the extension line on the front surface of the second flat surface portion 64 and the second flat surface portion 64. The thickness center line may be directed toward the axis 46 of the member body 3.

In this way, the second flat surface portion 64 is inclined so that, for example, when an emergency load is input from the front to the vehicle body, the member main body 3 moves toward the rear of the vehicle as indicated by a virtual line A in FIG. This is because the bending force is restricted by the tension force of the inclined second flat surface portion 64. 7 and 8, if the reinforcing bead 71 is provided in the reinforcing portion 53, it is possible to more effectively prevent the bending of the member body 3 described above. It is effective to provide the reinforcing beads 71 so as to extend substantially horizontally at least at the same height as the axis 46 of the member main body 3 in the reinforcing portion 53.

Incidentally, when the space portion 41 extending vertically is provided in the front-rear direction fixing portion 7, as shown by the phantom line B in FIG. 3, the member fixing surface 51 and the vehicle body contact fixing surface 52 are rectangular. In general, an L-shaped reinforcing portion 53 is provided. However, if this is done, the longitudinal dimension of the space portion 41 extending in the vertical direction becomes large and there is a risk of being crushed. Therefore, an additional reinforcing material (for example, the bolt 33 is passed inside the space portion 41 extending in the vertical direction. It is necessary to provide a collar and a sleeve. In order to install an additional reinforcing material, an operation of fixing the additional reinforcing material to the front-rear direction fixing portion 7 and the reinforcing portion 53 in the space portion 41 that extends vertically (narrow) is performed. This task is difficult. In addition, the cost is increased by providing an additional reinforcing material and by the amount required to change the bolt 33 to a long and sturdy one. Therefore, the rectangular reinforcing structure is not preferable.

Further, in order to prevent the member main body 3 from being bent toward the rear of the vehicle or the like, as shown by an imaginary line C in FIG. 3, the member fixing surface 51 and the vehicle body contact fixing surface 52 are triangular. It is ideal to provide the diagonal reinforcing portion 53 as described above. However, in this case, since the reinforcing portion 53 is separated from the member fixing surface 51 and the vehicle body abutting fixing surface 52, the fixing of the side bracket 5 with the general tool 34 in the vehicle front-rear direction 6 and the exterior as described later are performed. Both the holding of the member main body 3 in the direction of the axis 46 by the assisting device and the conveyance of the member main body 3 (or a cockpit module configured around the member main body 3) become difficult.

Therefore, as described above, the reinforcing portion 53 is formed in an inwardly bent shape having the first flat surface portion 62 extending in the vehicle front-rear direction 6 and the inclined second flat surface portion 64, so that the reinforcing portion 53 is a member fixing surface. 51, the side bracket 5 is fixed in the vehicle front-rear direction 6 with a general tool 34 so as to come close to the vehicle body contact fixing surface 52, and the member body 3 is held in the direction of the axis 46 by an external assisting device or the member Making it easy to carry the main body 3 together and preventing the member main body 3 from being bent toward the rear of the vehicle can be established at a time.

A bent edge 66 that is bent by a required amount toward the front-rear direction fixing portion 7 side or the like is provided at the edge of the reinforcing portion 53. The bent edge portion 66 serves as an attachment margin for the reinforcing portion 53 with respect to the front-rear direction fixing portion 7, and each surface (first flat surface portion 62, curved surface portion 63, second surface) of the reinforcing portion 53 with respect to the front-rear direction fixing portion 7. It also functions as a space forming portion for separating the flat surface portion 64) and forming a space portion 41 and the like extending vertically between the front-rear direction fixing portion 7 and the reinforcing portion 53.

Further, by providing the bent edge portion 66, the inclined second flat surface portion 64 can be brought closer to an ideal inclined state for preventing the bending of the member main body 3 as indicated by a virtual line C. Become.

More specifically, a gap forming portion 67 that extends inward in the vehicle width direction 2 toward the edge portion of the member fixing surface 51 of the front-rear direction fixing portion 7 is formed at the edge portion of the first flat surface portion 62. As a single unit. In this case, the rear edge portion of the first flat surface portion 62 and the rear edge portion of the member fixing surface 51 are substantially semicircular when viewed from the side, and the gap forming portion 67 is a continuous semicircular arc shape. .

Further, a gap forming portion 68 extending forward of the vehicle toward the vehicle body contact fixing surface 52 of the front-rear direction fixing portion 7 is formed as a bent edge portion 66 (along the vertical direction 17) at the edge portion of the second flat surface portion 64. It is provided integrally. The gap forming portion 68 is disposed in contact with the bent edge portion 57 of the front-rear direction fixing portion 7 in a state opposite to the bent edge portion 57. The space portion 41 extending vertically is provided on the front side of the reinforcing portion 53 mainly by separating the front-rear direction fixing portion 7 and the reinforcing portion 53 in the vehicle front-rear direction 6 by the gap forming portion 68.

The reinforcing portion 53 is integrated with the front-rear direction fixing portion 7 by welding the bent edge portion 66 (substantially the entire area of the gap forming portions 67, 68) to the front-rear direction fixing portion 7 in a continuous line shape. ing.

<Operation> The operation of this embodiment will be described below.

The front part of the vehicle body can be reinforced by attaching the steering member 1 extending in the vehicle width direction 2 between the left and right vehicle body panels 4 using the side brackets 5 provided at both ends thereof. Further, the steering member 21 can be supported by the steering member 1. The steering member 1 is supported on the floor panel by the stay 16 at an intermediate portion thereof.

Furthermore, devices such as an air bag device are attached to the member main body 3. A force applied to the member main body 3 when the airbag device is operated becomes a torsional force 45 and is transmitted to the side bracket 5. For this reason, the side bracket 5 needs to have rigidity that can receive the torsional force 45.

<Effect> According to this embodiment, the following effects can be obtained.

(Effect 1) While providing the side bracket 5 which has the front-back direction fixing | fixed part 7 fixed to the vehicle front-back direction 6 with respect to a vehicle body, the front-back direction fixing | fixed part 7 comprises the hollow body which has the space part 41 extended up and down. I did it. And since the side bracket 5 has the front-back direction fixing | fixed part 7, the steering member 1 can support the gravity center 22 of the steering column 21, or its vicinity. Under the present circumstances, the rigidity of the side bracket 5 can be raised by making the front-back direction fixing | fixed part 7 into the hollow body which has the space part 41 extended up and down. As a result, for example, the torsional force 45 (force in the rotational direction about the axis 46 of the member body 3) applied to the member body 3 when the airbag device attached to the member body 3 is activated, It can be received by the side bracket 5. Further, since the rigidity of the side bracket 5 is increased by the space portion 41 extending vertically, the thickness of the side bracket 5 can be suppressed by that amount, and the weight of the side bracket 5 can be reduced.

(Effect 2) The front-rear direction fixing portion 7 is provided with at least a reinforcing portion 53 (space forming member) that constitutes a space portion 41 extending vertically between the member fixing surface 51 and the vehicle body contact fixing surface 52. It is good as a thing. Thereby, the side bracket 5 which has the front-back direction fixing | fixed part 7 can be reliably made into a highly rigid member (hollow body) with the simple structure that the reinforcement part 53 is provided.

(Effect 3) The reinforcing portion 53 may block the end portion of the member body 3 having a cylindrical shape. As a result, the reinforcing portion 53 closes the end portion of the member main body 3 having a cavity therein, and at the same time, the reinforcing portion 53 forms a space portion 41 extending vertically in the side bracket 5, so that the entire steering member 1 is In addition, a single hollow body (space coupling body) in which the hollow inside the member main body 3 and the space portion 41 extending in the vertical direction of the side bracket 5 are connected can be obtained.

Therefore, since the rigidity of the steering member 1 is further increased, a force acting on the member main body 3 (for example, (vertical) vibration of the steering column 21 attached to the member main body 3, a torsional force 45 by the airbag device, etc.) ), The required rigidity can be easily secured. As a result, it is not necessary to ensure the rigidity by increasing the cross section (or diameter dimension) of the member main body 3 as before, and the increase in the weight of the member main body 3 and the cost increase can be suppressed correspondingly.

Further, the reinforcing portion 53 has a through hole 61 communicating with the inside of the member main body 3. Accordingly, the central portion of the member main body 3 can be gripped (using an external assisting device or the like) using the through hole 61. In addition, the through hole 61 can be used as a fastening portion such as a temporary bracket (a bracket that is temporarily used in an external assisting device).

Generally, a large number of heavy parts such as an instrument panel 24, an air conditioning unit, a wire harness, an airbag device, and a steering column 21 are attached to the steering member 1. A cockpit module is constructed by assembling them in advance before assembling them to the vehicle body.

Therefore, the steering member 1 is subjected to loads and moments due to the various large parts described above. By using the through hole 61 to grip the center of the member body 3 with an external assisting device or the like, When the steering member 1 or the cockpit module is handled with an external assisting device or the like, the influence of the load or moment acting on the steering member 1 can be minimized.

Furthermore, when the steering member 1 and the cockpit module are lifted by holding the center portion of the member main body 3 with an external assisting device or the like using the through-hole 61, the steering member 1 and the cockpit module are lifted by their own weight. It is difficult for the gripping posture and the gripping angle (the angle in the rotational direction around the member main body 3) to shift (as compared to the case of gripping other than the central portion of the member main body 3). Accordingly, it is possible to eliminate the need to separately set an auxiliary component (strength component) or the like in order to prevent a shift in the gripping posture or the gripping angle. As a result, an increase in the weight of the steering member 1 and an increase in cost can be suppressed as much as the auxiliary parts can be eliminated.

In addition, since it is difficult for the gripping posture and the gripping angle to shift, when the steering member 1 or the cockpit module is assembled to the vehicle body, for example, a piping of an air conditioning unit attached to the steering member 1 is provided on the front wall 13 of the passenger compartment. It is possible to avoid problems such as being unable to enter the pipe insertion hole.

(Effect 4) The space portion 41 extending vertically may be capable of preventing deformation due to the torsional force 45 acting on the member main body 3. Thereby, the member main body 3 and the front-rear direction fixing portion 7 can be made not to be deformed or hardly deformed with respect to the torsional force 45.

(Effect 5) The space 41 extending vertically may have a substantially triangular shape or a substantially L shape in plan view. Thereby, the member main body 3 and the front-back direction fixing | fixed part 7 can be made into a structure strong with respect to the twisting force 45 efficiently without waste.

(Effect 6) The vertically extending space 41 having a substantially triangular shape or a substantially L shape in plan view has a lateral portion extending in the vehicle width direction 2 on the front side, and the vehicle longitudinal direction on the end side of the member main body 3. It is good also as what has the vertical side part extended to 6. FIG. Thereby, the space part 41 extended up and down can be made into the optimal shape suitable for the shape of the front-back direction fixing | fixed part 7. FIG.

(Effect 7) The reinforcing portion 53 includes a first flat surface portion 62 that extends along the member fixing surface 51 of the front-rear direction fixing portion 7, and the first flat surface portion 62 toward the vehicle body contact fixing surface 52 of the front-rear direction fixing portion 7. And the second flat surface portion 64 is located on the front side of the axis 46 of the member main body 3 and is inclined obliquely extending toward the position of the axis 46 or the rear side thereof. You may make it become a plane. Thereby, for example, when an emergency load is input to the vehicle body from the front, the member body 3 can be restrained from being bent toward the rear of the vehicle by the tension force of the inclined second flat surface portion 64.

Further, the side bracket 5 is fixed in the vehicle front-rear direction 6 by a general tool 34, and the member body 3 is held and transported in the direction of the axis 46 by an external assisting device. can do.
