　車輪速センサー１１２は、センサーカバー１１３に連結されて小組体とされ、小組体の状態でボトムケース９６に組み付けられる。
　詳細には、車輪速センサー１１２は、検出部１１２ｂがセンサーカバー１１３の筒部１２６ａに挿通されるとともに、センサー連結ボルト１２５によってセンサーカバー１１３に連結され、小組体となる。車輪速センサー１１２は、小組体の状態では、検出部１１２ｂが検出部挿通孔１２６ｃに挿通されることで回り止めされ、センサーカバー１１３に対して適正に取り付けられる。
　次いで、上記小組体は、車輪速センサー１１２がセンサー用凹部１２１に入るようにボトムケース９６にセットされ、センサーカバー固定ボルト１２４，１２４によって固定される。
　すなわち、車輪速センサー１１２は、センサーカバー１１３を介してボトムケース９６の内側面９６ａに取り付けられる。センサー連結ボルト１２５の頭部は、センサー用凹部１２１内に収納される。 The wheel speed sensor 112 is connected to the sensor cover 113 to form a small assembly, and is assembled to the bottom case 96 in a small assembly state.
In detail, the wheel speed sensor 112 is inserted into the cylindrical portion 126 a of the sensor cover 113 and connected to the sensor cover 113 by the sensor connection bolt 125 to form a small assembly. In the state of the small assembly, the wheel speed sensor 112 is prevented from rotating by inserting the detection unit 112 b into the detection unit insertion hole 126 c, and is properly attached to the sensor cover 113.
Next, the small assembly is set in the bottom case 96 so that the wheel speed sensor 112 enters the sensor recess 121, and is fixed by the sensor cover fixing bolts 124, 124.
That is, the wheel speed sensor 112 is attached to the inner side surface 96 a of the bottom case 96 via the sensor cover 113. The head of the sensor connection bolt 125 is housed in the sensor recess 121.
　車輪速センサー１１２は、ボトムケース９６の内側面９６ａに取り付けられるため、車両側面視では、車輪速センサー１１２のケース部１１２ａ及び検出部１１２ｂはボトムケース９６に隠れ、外側から視認されない。詳細には、ケース部１１２ａの後端は、Ｖ字形状部１０２の後縁１０２ａよりも前方に位置し、ケース部１１２ａはボトムケース９６に隠れる。このため、車輪速センサー１１２が目立つことを防止でき、外観性が良い。また、車輪速センサー１１２を取り付けるための専用のステーを省略できるため、部品単数を削減できるとともに、外観性が良い。 The wheel speed sensor 112 is attached to the inner side surface 96a of the bottom case 96. Therefore, in the vehicle side view, the case portion 112a and the detection unit 112b of the wheel speed sensor 112 are hidden by the bottom case 96 and not viewed from the outside. Specifically, the rear end of the case portion 112 a is located forward of the rear edge 102 a of the V-shaped portion 102, and the case portion 112 a is hidden by the bottom case 96. For this reason, it can prevent that the wheel speed sensor 112 stands out, and the appearance is good. In addition, since a dedicated stay for attaching the wheel speed sensor 112 can be omitted, the number of parts can be reduced and the appearance is good.
　また、ボトムケース９６の内側面９６ａに設けられるセンサーカバー１１３は、比較的小型であり、車両側面視において、その全体がボトムケース９６に隠れる。このため、センサーカバー１１３が目立つことを防止できる。
　車輪速センサー１１２のケーブル１１２ｄは、Ｖ字形状部１０２とブレーキキャリパー５８の前縁とによって区画される開口１０３を通って内側面９６ａ側からボトムケース９６の外側へ出て、上方に配索される。これにより、開口１０３を利用する簡単な構造でケーブル１１２ｄの配索方向をガイドできる。 Further, the sensor cover 113 provided on the inner side surface 96 a of the bottom case 96 is relatively small, and the whole thereof is hidden in the bottom case 96 in a side view of the vehicle. Therefore, the sensor cover 113 can be prevented from standing out.
The cable 112d of the wheel speed sensor 112 is routed upward through the opening 103 defined by the V-shaped portion 102 and the front edge of the brake caliper 58 from the inner side surface 96a to the outside of the bottom case 96. Ru. Thereby, the direction of cable 112 d can be guided in a simple structure using the opening 103.
　ブレーキキャリパー支持部９８の下側アーム部９９と上側アーム部１００とは、結合部１０１によって基端部が互いに結合され、Ｖ字形状部１０２を構成する。これにより、ブレーキキャリパー支持部９８を軽量にすることができるとともに、ブレーキキャリパー支持部９８の強度及び剛性を結合部１０１によって増加させることができる。この結合部１０１は、Ｖ字形状部１０２の底部であり、下側アーム部９９及び上側アーム部１００に比して面積を確保し易い。このため、結合部１０１に車輪速センサー取付部１２０を容易に設けることができる。 The lower arm 99 and the upper arm 100 of the brake caliper support 98 are connected to each other at their base ends by the joint 101 to form a V-shaped section 102. As a result, the weight of the brake caliper support 98 can be reduced, and the strength and rigidity of the brake caliper support 98 can be increased by the connecting portion 101. The connecting portion 101 is a bottom portion of the V-shaped portion 102, and can easily secure an area as compared with the lower arm portion 99 and the upper arm portion 100. For this reason, the wheel speed sensor attachment portion 120 can be easily provided in the coupling portion 101.
　図２に示すように、Ｖ字形状部１０２の結合部１０１は、車両側面視でパルサローター１１１の被検出部１１５及び取付部１１７に重なる。このため、被検出部１１５及び取付部１１７を結合部１０１によって隠すことができ、外観性が良い。
　また、被検出部１１５の外周１１５ｃ（図２）は、Ｖ字形状部１０２の後縁１０２ａにおける結合部１０１の部分よりも車軸２ａ側に位置する。このため、被検出部１１５をＶ字形状部１０２によって効率良く隠すことができる。なお、パルサローター１１１の取付部１１７の先端部を、Ｖ字形状部１０２の後縁１０２ａにおける結合部１０１の部分と車軸２ａとの間に位置させ、取付部１１７をＶ字形状部１０２によって全体的に隠す構成としても良い。 As shown in FIG. 2, the connecting portion 101 of the V-shaped portion 102 overlaps the detected portion 115 and the mounting portion 117 of the pulsar rotor 111 in a side view of the vehicle. Therefore, the detection target portion 115 and the attachment portion 117 can be hidden by the connecting portion 101, and the appearance is good.
Further, the outer periphery 115 c (FIG. 2) of the detection target 115 is located closer to the axle 2 a than the portion of the connecting portion 101 at the rear edge 102 a of the V-shaped portion 102. Therefore, the detection target portion 115 can be efficiently hidden by the V-shaped portion 102. The tip of the mounting portion 117 of the pulsar rotor 111 is positioned between the portion of the connecting portion 101 at the rear edge 102a of the V-shaped portion 102 and the axle 2a, and the mounting portion 117 is entirely configured by the V-shaped portion 102. It is good also as composition that hides.

　この構成によれば、車軸２ａを支持するボトムケース９６に車輪速センサー１１２が取り付けられるため、車輪速センサー１１２のための専用のステーを省略でき、簡単な構造で車輪速センサー１１２を支持できるとともに外観性を向上できる。さらに、車輪速センサー１１２は、ボトムケース９６における内側面９６ａに取り付けられるため、車両側面視ではボトムケース９６によって隠れる。このため、車輪速センサー１１２が目立つことを防止でき、外観性を向上できる。 As described above, according to the first embodiment to which the present invention is applied, the motorcycle 1 includes the pair of left and right front forks 24 and 24 supporting the front wheel 2 and the pulsar rotor 111 provided on the front wheel 2 , And a wheel speed sensor 112 for detecting the rotation of the pulsar rotor 111, and the front forks 24, 24 have a bottom case 96 for supporting the axle 2a of the front wheel 2 at the lower end. The bottom case 96 has a brake caliper support 98 supporting a brake caliper 58 for braking the front wheel 2 behind the axle 2a, and the pulsar rotor in the bottom case 96 between the axle 2a and the brake caliper 58 in a vehicle side view A wheel speed sensor mounting portion 120 to which the wheel speed sensor 112 is attached is provided on an inner side surface 96 a which is a surface on the side 111.
According to this configuration, since the wheel speed sensor 112 is attached to the bottom case 96 supporting the axle 2a, a dedicated stay for the wheel speed sensor 112 can be omitted, and the wheel speed sensor 112 can be supported with a simple structure. The appearance can be improved. Furthermore, since the wheel speed sensor 112 is attached to the inner side surface 96 a of the bottom case 96, the wheel speed sensor 112 is hidden by the bottom case 96 in a vehicle side view. For this reason, it can prevent that the wheel speed sensor 112 stands out, and the appearance can be improved.
　また、ブレーキキャリパー支持部９８は、ブレーキキャリパー５８の上端部５８ａ及び下端部５８ｂを支持すべく２本で延びる下側アーム部９９及び上側アーム部１００と、下側アーム部９９と上側アーム部１００とを結合する結合部１０１とを備え、車輪速センサー取付部１２０は、結合部１０１に設けられる。この構成によれば、結合部１０１によってブレーキキャリパー支持部９８を補強できるとともに、結合部１０１を利用して車輪速センサー１１２が目立ち難い位置に車輪速センサー取付部１２０を設けることができる。
　また、下側アーム部９９、上側アーム部１００、及び結合部１０１は、車両側面視でＶ字形状部１０２を形成し、車輪速センサー取付部１２０は、車軸２ａの後方でＶ字形状部１０２の底部となる結合部１０１に設けられる。これにより、ブレーキキャリパー支持部９８がＶ字形状であるため、ブレーキキャリパー支持部の形状をシンプルにして外観性を向上できるとともに、ブレーキキャリパー支持部９８を軽量に構成できる。また、ブレーキキャリパー支持部９８のＶ字形状部１０２の結合部１０１は、Ｖ字形状部１０２において面積を確保し易い部分であるため、車輪速センサー取付部１２０を容易に設けることができる。

　また、車輪速センサー取付部１２０は、車輪速センサー１１２が収納されるセンサー用凹部１２１を備える。これにより、車輪速センサー１１２をボトムケース９６に取り付ける構成であっても、車輪速センサー１１２及びボトムケース９６を車幅方向にコンパクトに設けることができる。 Furthermore, a brake disc 57 fixed to the front wheel 2 and sandwiched by the brake calipers 58 is provided, and the pulsar rotor 111 has a ring-shaped detected portion 115 and an attaching portion 117 projecting radially outward from the detected portion 115. And is attached to the brake disc 57 via the attachment portion 117, and the coupling portion 101 of the V-shaped portion 102 overlaps the attachment portion 117 in a side view of the vehicle. As a result, the mounting portion 117 can be hidden by the connecting portion 101 of the V-shaped portion 102, and the appearance is good.
In addition, the wheel speed sensor mounting unit 120 includes a sensor recess 121 in which the wheel speed sensor 112 is housed. Thus, even if the wheel speed sensor 112 is attached to the bottom case 96, the wheel speed sensor 112 and the bottom case 96 can be compactly provided in the vehicle width direction.
　また、車輪速センサー取付部１２０は、車輪速センサー１１２をボトムケース９６に固定するセンサーカバー固定ボルト１２４，１２４が挿通される複数の固定穴部１２２，１２３を備え、センサー用凹部１２１は、固定穴部１２２，１２３の間に設けられる。これにより、車輪速センサー１１２をセンサー用凹部１２１の両側に設けられるセンサーカバー固定ボルト１２４，１２４で固定できるため、車輪速センサー１１２を強固に固定できる。
