Description

【０００１】
【発明の属する技術分野】
本発明は自動二輪車のアンチロックブレーキシステム（以下、ＡＢＳと記す）油圧ユニット組立体及びＡＢＳ油圧ユニットの取付構造の改良に関する。
【０００２】
【従来の技術】
従来、自動二輪車のＡＢＳ油圧ユニットの取付構造として、ＡＢＳ油圧ユニットをユニットホルダを使用して取付る方法が知られている（例えば、特許文献１参照。）。
【０００３】
【特許文献１】
特開平８−１１３１７９号公報（第３頁、６頁、図３）
【０００４】
図６は特許文献１の図３の再掲図である。ただし、符号は振り直す。
ＡＢＳ油圧ユニット１０１は油圧ポンプ１０２と電動モータ１０３とからなり、油圧ポンプ１０２からの油圧ホース１０４、１０５は、車体フレーム１０６のタンクレール１０７、１０８の内側に沿って車体前方へ配管される。
【０００５】
ＡＢＳ油圧ユニット１０１に、自動二輪車の走行時に受ける路面からの振動やエンジンからの振動が伝わることは好ましくない。そこで、車体フレームにクッション部材を介して、ＡＢＳ油圧ユニット１０１を取付る。
【０００６】
【発明が解決しようとする課題】
ＡＢＳ油圧ユニット１０１は、車体フレームにフローティング支持されいるため、ある程度移動する。この移動を吸収させるために、油圧ホース１０４、１０５は可撓性に富むゴムホースが採用される。
しかし、可撓性に富むゴムホースは、油圧が高圧化すると微小であるが拡径し、油圧が下がると元の径に戻る。
【０００７】
圧力伝達を考えた場合、油圧ホースの径が変化すると制御精度が低下する虞がある。
そこで、剛性の高い金属パイプや樹脂パイプを、油圧配管の要部に介在させることが望まれる。
【０００８】
組立ラインにおいて、車体フレームへＡＢＳ油圧ユニット１０１を迅速に組付けることを考えると、予め高剛性パイプをＡＢＳ油圧ユニット１０１に組付けておく必要がある。
【０００９】
この結果、ＡＢＳ油圧ユニット１０１から高剛性パイプが片持ち梁状に延びた組立体で、部品置き場から車体フレームへ運搬することになり、この運搬中に高剛性パイプを掴んだり、付近の物体や車体フレーム自体に接触したりしないように、作業者は注意を払う必要がある。高剛性パイプを何処かに接触させると、高剛性パイプの基部に負荷が加わる虞があるからである。
【００１０】
また、可撓性ホースは振動に強いが、高剛性パイプは長期にわたって振動を受けると疲労し劣化する虞があるので、高剛性パイプの外径を増すなどの振動対策を講じる必要がある。
そのため、従来、油圧経路の要部を高剛性パイプ化することが、困難であると考えられてきた。
【００１１】
【課題を解決するための手段】
本発明者らは、要部を高剛性パイプ化する研究を進める中で、添え木状のステーを付加すれば、従来の課題を解決し、要部を高剛性パイプ化することができることに気づいた。
すなわち、請求項１のＡＢＳ油圧ユニット組立体は、ＡＢＳ油圧ユニットと、このＡＢＳ油圧ユニットから延ばした油圧パイプと、この油圧パイプの先端をＡＢＳ油圧ユニットに機械的に連結するステーとからなる。
【００１２】
ＡＢＳ油圧ユニットと、油圧パイプの先端とをステーで機械的に連結したので、ＡＢＳ油圧ユニットに対して油圧パイプの先端が変位しない。
この結果、自動二輪車の走行中、起動時、制動時などにおいて、油圧パイプはＡＢＳ油圧ユニットと一体になって振動するため、油圧パイプの変形などを防止することができる。
【００１３】
また、高剛性パイプをＡＢＳ油圧ユニットに組付けた状態で高剛性パイプを掴んだり、組立時に、仮に油圧パイプが何処かに接触しても、ステーの存在により、油圧パイプに負荷が加わる心配が少い。そのため、組付け作業を容易にすることができる。
【００１４】
請求項２のＡＢＳ油圧ユニットの取付構造は、請求項１記載のＡＢＳ油圧ユニット組立体と、このＡＢＳ油圧ユニット組立体を支持させるために車体フレームに設けた支持部材と、この支持部材にＡＢＳ油圧ユニット組立体を結合させる結合手段とからなる。
【００１５】
車体フレーム側に設けた支持部材に、ＡＢＳ油圧ユニット組立体を載せ、このＡＢＳ油圧ユニット組立体をボルトなどの結合手段で支持部材に結合する。
【００１６】
ＡＢＳ油圧ユニットに対して油圧パイプの先端が変位しないので、自動二輪車の走行中、起動時、制動時などにおいて、油圧パイプはＡＢＳ油圧ユニットと一体になって振動するため、油圧パイプの変形などを防止することができる。
【００１７】
請求項３のＡＢＳ油圧ユニットの取付構造は、支持部材とＡＢＳ油圧ユニット組立体との間に弾性部材を介在させたことを特徴とする。
【００１８】
支持部材とＡＢＳ油圧ユニット組立体との間に弾性部材を介在させたことにより、自動二輪車の走行中、起動時、制動時などの振動は、車体フレームからＡＢＳ油圧ユニット組立体に伝わる時に、この弾性部材で吸収され軽減される効果がある。
【００１９】
【発明の実施の形態】
本発明の実施の形態を添付図に基づいて以下に説明する。なお、図面は符号の向きに見るものとする。
図１は本発明に係る自動二輪車の一例を示す側面図であり、自動二輪車１０は、メインフレーム１１と、このメインフレーム１１の前部に取付たヘッドパイプ１２と、このヘッドパイプ１２の下方に取付た前輪１３と、車体中央のエンジンハンガ部１４で支えるエンジン１５と、ピボット１６で支えたスイングアーム１７の後部に取付た後輪１８と、車体上部の燃料タンク２１と、この燃料タンク２１の後部に取付たシート２２と、このシート２２の下方に取付たシートレール２３、２４と、このシートレール２４に取付た本発明に係るＡＢＳ油圧ユニット組立体３０とからなる構成体である。
ここで、シートレール２４は車体フレームの一部であるから、以後、シートレール２４を車体フレーム２４と表現する。
【００２０】
また、図１では、２５はドライブチェーン、２６はマフラー、２７はステップ、２８はチェンジペダル、２９はステアリングハンドルである。
さらに、ＡＢＳ油圧ユニット組立体３０から延びるラバーチューブは、マスターシリンダ４１とリアクッション下部取付座４２と連結する。一方、マスターシリンダ４１から後方に延びるラバーチューブは、リアブレーキキャリバ４４と連結する。
【００２１】
以下、本発明のＡＢＳ油圧ユニット組立体について詳しく説明する。
図２は図１の２部拡大図であり、ＡＢＳ油圧ユニット組立体３０は、ＡＢＳ油圧ユニット３１と、このＡＢＳ油圧ユニット３１上部に備えた第一接続部材３２と、この接続部材３２を介してＡＢＳ油圧ユニット３１から延ばした油圧パイプ３３と、この油圧パイプ３３の先端を第二接続部材３４を介してボルト３５でステー３６の一端に連結し、このステー３６の他端をＡＢＳ油圧ユニット３１に機械的に連結することからなる構成体である。
【００２２】
また、ＡＢＳ油圧ユニット組立体３０と車体フレーム２４との取付構造は、ＡＢＳ油圧ユニット組立体３０と、このＡＢＳ油圧ユニット組立体３０を支持させるために車体フレーム２４に設けた支持部材５１と、この支持部材５１とＡＢＳ油圧ユニット組立体３０をボルト５２により結合する結合手段とからなる。
ここで、支持部材５１とＡＢＳ油圧ユニット組立体３０との間に弾性部材５３を介在させたことを特徴とする。
【００２３】
以上の構成からなるＡＢＳ油圧ユニット組立体の作用を次に説明する。
図３はＡＢＳ油圧ユニット組立体の作用図である。
（ａ）は自動二輪車が停止状態の場合を示し、ＡＢＳ油圧ユニット組立体３０のＡＢＳ油圧ユニット３１は、地面と水平状態である。この時の油圧パイプ３３のＵ字曲げ部の内径長さをｔ、油圧パイプ３３のＬ曲げ部の角度をθとする。
【００２４】
（ｂ）は自動二輪車の前方に重心がかかった場合を示し、ＡＢＳ油圧ユニット３１とステー３６と支持部材５１とボルト５２と弾性部材５３からなるＡＢＳ油圧ユニット組立体３０の車体フレーム２４（図示せず）との取付部は、自動二輪車の重心が前方にかかることにより、弾性部材５３の前方部が縮み、後方部が伸びる。
【００２５】
その結果、ＡＢＳ油圧ユニット組立体３０は矢印▲１▼のように前方に傾くが、油圧パイプ３３とステー３６が連結されている（図２参照。）ために、油圧パイプ３３に過大な応力は発生せず、油圧パイプ３３のＵ字曲げ部の内径長さ及び油圧パイプ３３のＬ曲げ部の角度は、各々ｔ、θで一定で油圧パイプ３３の変形を防止できる。
【００２６】
（ｃ）は自動二輪車の後方に重心がかかった場合を示し、ＡＢＳ油圧ユニット３１とステー３６と支持部材５１とボルト５２と弾性部材５３からなるＡＢＳ油圧ユニット組立体３０の車体フレーム２４（図示せず）との取付部は、自動二輪車の重心が後方にかかることにより、弾性部材５３の後方部が縮み、前方部が伸びる。
【００２７】
その結果、ＡＢＳ油圧ユニット組立体３０は矢印▲２▼のように後方に傾くが、油圧パイプ３３とステー３６が連結されている（図２参照。）ために、油圧パイプ３３に過大な応力は発生せず、油圧パイプ３３のＵ字曲げ部の内径長さ及び油圧パイプ３３のＬ曲げ部の角度は、各々ｔ、θで一定で油圧パイプ３３の変形を防止できる。
【００２８】
図４は図２の比較例を示す図である。
（ａ）は油圧パイプ３３が連結する第二接続部材３４とボルト３５を、フレーム固定部品３９によって車体フレーム２４に連結した場合である。
この時の油圧パイプ３３のＵ字曲げ部の内径長さをｔ１、油圧パイプ３３のＬ曲げ部の角度をθ１とする。
【００２９】
（ｂ）は自動二輪車の後方に重心がかかった場合を示し、ＡＢＳ油圧ユニット３１と支持部材５１とボルト５２と弾性部材５３と車体フレーム２４（図示せず）との取付部は、自動二輪車の重心が後方にかかることにより、弾性部材５３の後方部が縮み、前方部が伸びる。
【００３０】
その結果、ＡＢＳ油圧ユニット３１とＡＢＳ油圧ユニット３１から延びる油圧パイプ３３は矢印▲３▼のように後方に傾く。この時、油圧パイプ３３の先端は、図４（ａ）に示すように、接続部材３４とボルト３５とフレーム固定部品３９により車体フレーム２４に連結されているので、油圧パイプ３３の自由度が無くなる。
【００３１】
したがって、油圧パイプ３３のＵ字曲げ部の内径長さをｔ２、油圧パイプ３３のＬ曲げ部の角度をθ２とすれば、油圧パイプが応力により変形するので、ｔ２及びθ２は図４（ａ）のｔ１及びθ１より大きくなる。
この比較例では、以上のような応力による変形が繰返される可能性がある。
【００３２】
図５は本発明に係る別実施例を示す図であり、ＡＢＳ油圧ユニット組立体３０は、ＡＢＳ油圧ユニット３１と、このＡＢＳ油圧ユニット３１上部に備えた接続部材３２と、この接続部材３２を介してＡＢＳ油圧ユニット３１から延ばした油圧パイプ３３と、この油圧パイプ３３の先端を第二接続部材３４を介してボルト３５でステー３６に連結し、このステー３６の他端を支持部材５１とボルト５２と弾性部材５３を用いて、ＡＢＳ油圧ユニット３１に機械的に連結することからなる構成体である。
【００３３】
図５と図２との相違点は、ＡＢＳ油圧ユニット３１と車体フレーム２４との取付構造が異なる点である。具体的な相違点は、図５では、支持部材５１と弾性部材５３の接触において、支持部材５１が弾性部材５３の中央に位置し、弾性部材５３の下面に接してステー３６が配置されている。
したがって、ＡＢＳ油圧ユニット３１の取付高さを低くできるため、重心を低くすることができる。
【００３４】
尚、ＡＢＳ油圧ユニット組立体３０において、油圧パイプ３３の材質は金属製で剛性のあるものであれば特に種類は問わない。
油圧パイプ３３を金属製としてＡＢＳ油圧ユニット３１及びステー３６と連結したため、振動した際にＡＢＳ油圧ユニット３１と共に動く部分の剛性が高いことから、ブレーキ剛性を向上させることができる。
また、弾性部材５３は十分な弾力性があり、耐候性に優れるゴム系のものであれば特に種類は問わない。
【００３５】
【発明の効果】
本発明は上記構成により次の効果を発揮する。
請求項１によれば、ＡＢＳ油圧ユニットと、油圧パイプと、ステーで機械的に連結したので、ＡＢＳ油圧ユニットに対して油圧パイプの先端が変位しない。
この結果、自動二輪車の走行中、起動時、制動時などにおいて、油圧パイプはＡＢＳ油圧ユニットと一体になって振動するため、油圧パイプの変形などを防止することができる。
また、組立時に、仮に油圧パイプの先端が、何処かに接触しても、ステーの存在により、油圧パイプの形状が保持される。そのため、組付け作業を容易にすることができる。
【００３６】
請求項２では、ＡＢＳ油圧ユニット組立体は、ＡＢＳ油圧ユニットと、油圧パイプと、ステーで機械的に連結したものであるから、組立時に、仮に油圧パイプの先端が、何処かに接触しても、ステーの存在により、油圧パイプが傷む心配はない。そのため、組付け作業を容易にすることができる。
【００３７】
ＡＢＳ油圧ユニットに対して油圧パイプの先端が変位しないので、自動二輪車の走行中、起動時、制動時などにおいて、油圧パイプはＡＢＳ油圧ユニットと一体になって振動するため、油圧パイプの変形などを防止することができる。
【００３８】
請求項３では、支持部材とＡＢＳ油圧ユニット組立体との間に弾性部材を介在させたことにより、自動二輪車の走行中、起動時、制動時などの振動は、車体フレームからＡＢＳ油圧ユニット組立体に伝わる時に、この弾性部材で吸収され軽減される効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to an antilock brake system (hereinafter referred to as ABS) hydraulic unit assembly for a motorcycle and an improved mounting structure for the ABS hydraulic unit.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as an ABS hydraulic unit mounting structure for a motorcycle, a method of mounting an ABS hydraulic unit using a unit holder is known (for example, see Patent Document 1).
[0003]
[Patent Document 1]
JP-A-8-113179 (page 3, page 6, FIG. 3)
[0004]
FIG. 6 is a reproduction of FIG. However, the code is reassigned.
The ABS hydraulic unit 101 includes a hydraulic pump 102 and an electric motor 103, and hydraulic hoses 104 and 105 from the hydraulic pump 102 are piped forward along the inside of the tank rails 107 and 108 of the vehicle body frame 106.
[0005]
It is not preferable that the ABS hydraulic unit 101 receives vibrations from the road surface and vibrations from the engine that are received when the motorcycle is traveling. Therefore, the ABS hydraulic unit 101 is attached to the vehicle body frame via a cushion member.
[0006]
[Problems to be solved by the invention]
Since the ABS hydraulic unit 101 is floatingly supported by the body frame, it moves to some extent. In order to absorb this movement, rubber hoses with high flexibility are adopted as the hydraulic hoses 104 and 105.
However, a flexible rubber hose has a small diameter when the hydraulic pressure is increased, but expands, and returns to the original diameter when the hydraulic pressure decreases.
[0007]
When pressure transmission is considered, there is a risk that the control accuracy will be reduced if the diameter of the hydraulic hose changes.
Therefore, it is desired that a highly rigid metal pipe or resin pipe is interposed in the main part of the hydraulic piping.
[0008]
Considering the quick assembly of the ABS hydraulic unit 101 to the body frame in the assembly line, it is necessary to assemble a high-rigidity pipe to the ABS hydraulic unit 101 in advance.
[0009]
As a result, the high-rigidity pipe extends from the ABS hydraulic unit 101 in a cantilever shape and is transported from the parts storage to the vehicle body frame. During this transportation, the high-rigidity pipe is gripped, The operator needs to be careful not to touch the body frame itself. This is because if the high-rigidity pipe is brought into contact with somewhere, a load may be applied to the base of the high-rigidity pipe.
[0010]
In addition, although the flexible hose is strong against vibration, the high-rigidity pipe may be fatigued and deteriorated when subjected to vibration over a long period of time, and therefore it is necessary to take measures against vibration such as increasing the outer diameter of the high-rigidity pipe.
Therefore, conventionally, it has been considered difficult to make the main part of the hydraulic path into a highly rigid pipe.
[0011]
[Means for Solving the Problems]
The inventors of the present invention, while advancing research to make the main part a high-rigidity pipe, realized that if a splint-like stay was added, the conventional problem could be solved and the main part could be made a high-rigidity pipe. .
In other words, the ABS hydraulic unit assembly of claim 1 includes an ABS hydraulic unit, a hydraulic pipe extending from the ABS hydraulic unit, and a stay that mechanically connects the tip of the hydraulic pipe to the ABS hydraulic unit.
[0012]
Since the ABS hydraulic unit and the tip of the hydraulic pipe are mechanically connected by the stay, the tip of the hydraulic pipe is not displaced with respect to the ABS hydraulic unit.
As a result, the hydraulic pipe vibrates integrally with the ABS hydraulic unit during traveling, starting, braking, etc. of the motorcycle, so that deformation of the hydraulic pipe can be prevented.
[0013]
Also, if the high-rigidity pipe is attached to the ABS hydraulic unit, the high-rigidity pipe may be grabbed, or even if the hydraulic pipe touches somewhere during assembly, there is a concern that a load will be applied to the hydraulic pipe due to the presence of the stay. Little. Therefore, the assembling work can be facilitated.
[0014]
An ABS hydraulic unit mounting structure according to a second aspect includes an ABS hydraulic unit assembly according to the first aspect, a support member provided on a vehicle body frame for supporting the ABS hydraulic unit assembly, and an ABS hydraulic pressure on the support member. And coupling means for coupling the unit assemblies.
[0015]
An ABS hydraulic unit assembly is mounted on a support member provided on the vehicle body frame side, and the ABS hydraulic unit assembly is coupled to the support member by a coupling means such as a bolt.
[0016]
Since the tip of the hydraulic pipe is not displaced with respect to the ABS hydraulic unit, the hydraulic pipe vibrates integrally with the ABS hydraulic unit during running, starting, braking, etc. of the motorcycle. Can be prevented.
[0017]
The mounting structure of the ABS hydraulic unit according to claim 3 is characterized in that an elastic member is interposed between the support member and the ABS hydraulic unit assembly.
[0018]
By interposing the elastic member between the support member and the ABS hydraulic unit assembly, vibrations such as during running, starting and braking of the motorcycle are transmitted from the body frame to the ABS hydraulic unit assembly. There is an effect of being absorbed and reduced by the elastic member.
[0019]

Z)), the front part of the elastic member 53 is contracted and the rear part is extended when the center of gravity of the motorcycle is applied forward.
[0025]
As a result, the ABS hydraulic unit assembly 30 tilts forward as indicated by the arrow (1), but since the hydraulic pipe 33 and the stay 36 are connected (see FIG. 2), excessive stress is applied to the hydraulic pipe 33. The inner diameter length of the U-shaped bent portion of the hydraulic pipe 33 and the angle of the L bent portion of the hydraulic pipe 33 are constant at t and θ, respectively, and deformation of the hydraulic pipe 33 can be prevented.
[0026]
(C) shows a case where the center of gravity is applied to the rear of the motorcycle. The vehicle body frame 24 (not shown) of the ABS hydraulic unit assembly 30 comprising the ABS hydraulic unit 31, the stay 36, the support member 51, the bolt 52 and the elastic member 53 is shown. Z)), the rear part of the elastic member 53 contracts and the front part extends as the center of gravity of the motorcycle is applied to the rear.
[0027]
As a result, the ABS hydraulic unit assembly 30 is tilted rearward as indicated by the arrow (2), but since the hydraulic pipe 33 and the stay 36 are connected (see FIG. 2), excessive stress is applied to the hydraulic pipe 33. The inner diameter length of the U-shaped bent portion of the hydraulic pipe 33 and the angle of the L bent portion of the hydraulic pipe 33 are constant at t and θ, respectively, and deformation of the hydraulic pipe 33 can be prevented.
[0028]
FIG. 4 is a diagram showing a comparative example of FIG.
(A) is a case where the second connecting member 34 and the bolt 35 to which the hydraulic pipe 33 is connected are connected to the vehicle body frame 24 by the frame fixing part 39.
At this time, the inner diameter length of the U-shaped bent portion of the hydraulic pipe 33 is t1, and the angle of the L bent portion of the hydraulic pipe 33 is θ1.
[0029]
(B) shows the case where the center of gravity is applied to the rear of the motorcycle, and the mounting portions of the ABS hydraulic unit 31, the support member 51, the bolt 52, the elastic member 53, and the vehicle body frame 24 (not shown) are provided on the motorcycle. When the center of gravity is applied to the rear, the rear part of the elastic member 53 is contracted and the front part is extended.
[0030]
As a result, the ABS hydraulic unit 31 and the hydraulic pipe 33 extending from the ABS hydraulic unit 31 are inclined rearward as indicated by the arrow (3). At this time, as shown in FIG. 4A, the tip of the hydraulic pipe 33 is connected to the vehicle body frame 24 by the connecting member 34, the bolt 35, and the frame fixing part 39, so that the degree of freedom of the hydraulic pipe 33 is lost. .
[0031]
Therefore, if the inner diameter length of the U-shaped bent portion of the hydraulic pipe 33 is t2, and the angle of the L bent portion of the hydraulic pipe 33 is θ2, the hydraulic pipe is deformed due to stress, so t2 and θ2 are shown in FIG. Greater than t1 and θ1.
In this comparative example, there is a possibility that the deformation due to the stress as described above is repeated.
[0032]
FIG. 5 is a view showing another embodiment according to the present invention. An ABS hydraulic unit assembly 30 includes an ABS hydraulic unit 31, a connection member 32 provided on the ABS hydraulic unit 31, and the connection member 32. The hydraulic pipe 33 extended from the ABS hydraulic unit 31 and the tip of the hydraulic pipe 33 are connected to the stay 36 by the bolt 35 via the second connecting member 34, and the other end of the stay 36 is connected to the support member 51 and the bolt 52. And an elastic member 53 to mechanically connect to the ABS hydraulic unit 31.
[0033]
The difference between FIG. 5 and FIG. 2 is that the mounting structure of the ABS hydraulic unit 31 and the vehicle body frame 24 is different. Specifically, in FIG. 5, in the contact between the support member 51 and the elastic member 53, the support member 51 is positioned at the center of the elastic member 53, and the stay 36 is disposed in contact with the lower surface of the elastic member 53. .
Therefore, since the mounting height of the ABS hydraulic unit 31 can be lowered, the center of gravity can be lowered.
[0034]
In the ABS hydraulic unit assembly 30, the material of the hydraulic pipe 33 is not particularly limited as long as it is made of metal and has a rigidity.
Since the hydraulic pipe 33 is made of metal and connected to the ABS hydraulic unit 31 and the stay 36, the rigidity of the portion that moves together with the ABS hydraulic unit 31 when vibrated is high, so that the brake rigidity can be improved.
The elastic member 53 is not particularly limited as long as it is a rubber-based material having sufficient elasticity and excellent weather resistance.
[0035]
【The invention's effect】
The present invention exhibits the following effects by the above configuration.
According to the first aspect, since the ABS hydraulic unit, the hydraulic pipe, and the stay are mechanically connected, the tip of the hydraulic pipe is not displaced with respect to the ABS hydraulic unit.
As a result, the hydraulic pipe vibrates integrally with the ABS hydraulic unit during traveling, starting, braking, etc. of the motorcycle, so that deformation of the hydraulic pipe can be prevented.
Further, even if the tip of the hydraulic pipe contacts somewhere during assembly, the shape of the hydraulic pipe is maintained due to the presence of the stay. Therefore, the assembling work can be facilitated.
[0036]
In claim 2, since the ABS hydraulic unit assembly is mechanically connected by an ABS hydraulic unit, a hydraulic pipe, and a stay, even if the tip of the hydraulic pipe contacts somewhere during assembly. There is no worry that the hydraulic pipe will be damaged by the stay. Therefore, the assembling work can be facilitated.
[0037]
Since the tip of the hydraulic pipe is not displaced with respect to the ABS hydraulic unit, the hydraulic pipe vibrates integrally with the ABS hydraulic unit during running, starting, braking, etc. of the motorcycle. Can be prevented.
[0038]
According to the third aspect of the present invention, the elastic member is interposed between the support member and the ABS hydraulic unit assembly, so that vibrations during running, starting, braking, etc. of the motorcycle can be caused from the body frame to the ABS hydraulic unit assembly. This is effective in being absorbed and reduced by this elastic member.
