Fig. 2 is a partially enlarged view of fig. 1 showing a structure around the brake caliper 38 of the front wheel WF. Fig. 3 is a perspective view of the periphery of the caliper 38 as viewed from the rear right of the vehicle body. An upper support portion 43 for mounting the caliper 38 and a lower support portion 44 as a support portion are formed on the vehicle body rear side of the bottom bracket 42. The hydraulic caliper 38 has a pin-sliding type single plunger structure of female press, and upper and lower end portions of a support plate 48 (shown in dotted hatching) to which a slide pin is fixed are fixed to the upper support portion 43 and the lower support portion 44 by a 1 st bolt 45 and a 2 nd bolt 46, respectively.
The caliper 38 is formed with an upper projection 60 and a lower projection 61 for receiving the slide pin. A bleeder screw 62 for bleeding air is disposed on the vehicle body rear side of the upper projecting portion 60 as a projecting portion, and a docking adapter 66 connected to an end portion of a brake hose 64 is fixed to the vehicle body rear side of the bleeder screw 62 using a docking bolt 65.

A pad clip 69, which is a leaf spring, is provided radially outward of the brake pad 68 and between the brake caliper 38.
The wheel speed sensor 70 is fixed to a plate-like support portion 51 extending downward from the lower support portion 44 by a fastening member 71 such as a bolt directed in the vehicle width direction. The pulser ring 52 formed with a plurality of elongated holes 52a is fixed to the hub portion of the wheel hub 39, and the tip end of the sensor shaft 75 of the wheel speed sensor 70 is disposed in proximity to the pulser ring 52 through a through hole provided in the support portion 51.
A wire harness 72 for transmitting a sensor signal is connected to a cylindrical portion 74 of the sensor shaft 75 extending from the outside in the vehicle width direction to the front of the vehicle body. The wire harness 72 is routed upward of the vehicle body through the vehicle width direction inner side of the lower support portion 44. The retainer 50 for retaining the wire harness 72 is fixed to the vehicle width direction inner surface of the lower support portion 44 using a fastening member. The retainer 50 positions the wire harness 72 by retaining the grommet 49 made of rubber covering the wire harness 72.
On the other hand, a harness guide 47 that defines the arrangement position of the harness 72 is provided at a position below the 1 st bolt 45 of the upper support portion 43. The wire harness 72 inserted in the harness guide 47 is arranged above the vehicle body through between the 1 st bolt 45 and the upper side projection 60, and is bundled on the brake hose 64 side using the resin-made clamp 63 attached to the brake hose 64.
According to the above configuration, by mounting the wheel speed sensor 70 at the lower portion of the lower side support portion 44, it is possible to reduce the arrangement space of the wheel speed sensor 70 and prevent the wheel speed sensor 70 from protruding outward in the vehicle width direction to protect the wheel speed sensor 70. Further, since the plate-shaped support portion 51 extending downward from the lower support portion 44 is provided, and the wheel speed sensor 70 is fixed to the support portion 51 using the single fastening member 71 directed in the vehicle width direction, the assembling work of the wheel speed sensor 70 can be facilitated.
Further, since the wire harness 72 is routed above the vehicle body through the lower support portion 44 from the inside in the vehicle width direction, the wire harness 72 is shielded from the outside by the lower support portion 44, and the wire harness 72 can be protected from external forces, flying stones, and the like, and the appearance around the wheel speed sensor 70 can be improved.
Further, since the holder 50 for holding the wire harness 72 is attached to the vehicle width direction inner side surface of the lower support portion 44, even when the front fork 40 extends or contracts, the wire harness 72 can be prevented from contacting the wheel boss 39 or the like.
Further, after the wire harness 72 is guided upward of the vehicle body by passing through the vehicle width direction inner side of the lower support portion 44, the wire harness 72 is arranged upward of the vehicle body by passing through between the 1 st bolt 45 that fixes the caliper 38 to the upper support portion 43 and the upper projecting portion 60 provided on the caliper 38, and therefore, by sandwiching the wire harness 72 between the 2 projections, positioning of the wire harness 72 becomes easy, and the wire harness 72 can be protected against external force, flying stones, and the like.
Further, since the lower projecting portion 61 provided at a position below the caliper 38 and projecting outward in the vehicle width direction, the 2 nd bolt 46 for fixing the caliper 38 to the lower support portion 44, and the fastening member 71 for fixing the wheel speed sensor 70 are arranged in a linear shape in parallel when viewed from the vehicle body side, the plate portion 73 of the wheel speed sensor 70 is directed in the vehicle body front-rear direction, and 3 circles are directed in the longitudinal direction when viewed from the vehicle body side, and it is possible to impart a geometrically uniform design around the wheel speed sensor 70 and improve the appearance.
Further, since the harness guide 47 is disposed below between the 1 st bolt 45 and the upper projecting portion 60, even when the front fork 40 expands or contracts, the harness 72 can be prevented from contacting the 1 st bolt and the upper projecting portion 60. Further, by arranging the 1 st bolt, the upper projecting portion 60, and the harness guide 47 in a triangular shape when viewed from the vehicle body side, geometrically neat design can be provided and the appearance can be improved.
Fig. 4 is a perspective view of the wheel speed sensor 70. The wheel speed sensor 70 has a plate-like portion 73 as a mounting portion for mounting to the support portion 51. The plate-like portion 73 formed of a hard resin, a metal, or the like is oblong when viewed from the vehicle body side, a through hole 76 through which the fastening member 71 is inserted is formed on the vehicle body rear side, and a cylindrical portion 74 connected to the wire harness 72 is provided on the vehicle body front side of the vehicle width direction outer side surface 73 a. Further, a sensor shaft 75 protruding inward in the vehicle width direction is provided at a position closer to the vehicle body rear of the cylindrical portion 74 and closer to the vehicle body front of the through hole 76. The upper end surface 73b of the plate-like portion 73 is formed substantially parallel to the longitudinal direction of the cylindrical portion 74.
Thus, when the wheel speed sensor 70 is attached to the support portion 51, the cylindrical protrusion formed by the sensor shaft 75 is disposed in front of the fastening member 71 in the vehicle body, and the circles are disposed in parallel in the front-rear direction of the vehicle body, so that the periphery of the wheel speed sensor 70 can be geometrically designed to improve the appearance. The plate-like portion 73 as the mounting portion is not limited to the oblong shape shown in the above-described embodiment, and may be an extension portion having a square shape, a circular shape, a semicircular shape, or the like when viewed from the vehicle body side surface in accordance with the shape of the recessed portion 51a, and may be variously modified.
Fig. 5 is a perspective view of the periphery of the wheel speed sensor 70 as viewed from below at the rear right of the vehicle body. Fig. 6 is a right side view showing the structure of the support portion 51 in a state where the wheel speed sensor 70 is removed. The support portion 51 is provided with a recess 51a for accommodating the plate-like portion 73 of the wheel speed sensor 70. A female screw hole 53 to be screwed with the fastening member 71 and a through hole 54 through which the sensor shaft 75 passes are formed in the recess 51 a.
The recess 51a is formed with high accuracy by cutting the support portion 51 formed by casting or the like. This facilitates the positioning work when mounting the wheel speed sensor 70 on the support portion 51. Since the plate-shaped portion 73 is accommodated in the recess 51a, the movement of the plate-shaped portion 73 in the rotational direction is restricted, and therefore, the wheel speed sensor 70 can be fixed using the single fastening member 71 without increasing the number of working steps.
Further, since the upper end surface 73b of the plate-like portion 73 is along the lower surface 44a of the lower support portion 44 when the wheel speed sensor 70 is attached to the support portion 51, the plate-like portion 73, which is long in the front-rear direction, is directed in the vehicle body front-rear direction along the lower surface 44a of the lower support portion 44, and the appearance around the wheel speed sensor 70 can be further improved.
Fig. 7 is a rear view showing the configuration around the brake caliper 38. The wheel speed sensor 70 is fixed to the support portion 51, and is disposed so as to overlap the bottom bracket 42 at a position on the vehicle width direction inner side when viewed from the vehicle body rear. Thus, the wheel speed sensor 70 is disposed not only below the lower support portion 44 and on the rear side of the bottom bracket 42 but also on the vehicle width direction inner side, and the wheel speed sensor 70 is easily protected from external force, flying stones, and the like. Further, since it is difficult to visually recognize the wheel speed sensor 70 from the front and the side of the vehicle body, the appearance of the motorcycle 1 can be improved.
The form of the saddle-ride type vehicle, the shape and structure of the front fork, the shape and structure of the brake disc and the brake caliper, the shape and structure of the wheel speed sensor, the shape and structure of the support portion and the support portion, and the like are not limited to the above-described embodiments, and various modifications are possible. The utility model discloses a wheel speed sensor's installation structure not only can be applied to multiple two-wheeled motorcycle, can also be applied to and use the front fork to carry out the type tricycle of striding of shaft support to the front wheel.
