[0009] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the scope of the invention as claimed, and not all combinations of features described in the embodiments are necessarily essential to the invention. Two or more of the features described in the embodiments may be arbitrarily combined. Furthermore, the same reference numerals are used for the same or similar components, and redundant explanations will be omitted.

[0010] <Overview of saddle-type vehicle> 1 and 2 are schematic diagrams showing an overview of a saddle-ride type vehicle (hereinafter simply referred to as a vehicle) 100 according to one embodiment of the present invention, with FIG. 1 being a side view (right side view) and FIG. 2 being a front view. Vehicle 100 of this embodiment is exemplified as a motorcycle equipped with a front wheel FW and a rear wheel RW, but the present invention is also applicable to other types of saddle-ride type vehicles. In each drawing, arrow D1 indicates the fore-and-aft direction of vehicle 100, with Fr and Rr indicating the front and rear, respectively. Arrow D2 indicates the vehicle width direction, and R and L indicate the right and left.

[0011] The vehicle 100 includes a body frame 101 that forms its skeleton. A front wheel steering unit 102 is supported at the front end of the body frame 101, and a swing arm 105 is supported at the rear end so that it can swing freely. The front wheel steering unit 102 includes a pair of left and right front forks 103R, 103L that support the front wheel FW via an axle 112, and a steering handlebar 104 that is attached to the upper parts of the pair of front forks 103R, 103L via a top bridge (not shown). A front fender 111 is provided between the pair of front forks 103R, 103L. The front fender 111 is supported by the pair of front forks 103R, 103L and covers the upper part of the front wheel FW.

[0012] The swing arm 105 has its front end swingably supported by the body frame 101, and its rear end supports the rear wheel RW. An internal combustion engine 106 and a transmission 107 are supported by the body frame 101 in the area between the front wheel FW and the rear wheel RW. In this embodiment, the internal combustion engine 106 is a water-cooled, single-cylinder, four-stroke engine. The output of the internal combustion engine 106 is transmitted to the rear wheel RW via the transmission 107 and a chain transmission mechanism (not shown). The exhaust passage 108 includes an exhaust pipe 108a connected to an exhaust port and a silencer 108b. A fuel tank 109 is disposed above the internal combustion engine 106, and a seat 110 on which a rider sits is disposed behind the fuel tank 109.

[0013] <Wheel speed sensor> Please refer to Figure 3. Figure 3 is a detailed view of the configuration of the right side of the front wheel FW. A wheel speed sensor 1 that detects the rotation of the front wheel FW is provided at the lower end of the front fork 103R, and a pulser ring 3 is fixed to the right side of the front wheel FW. The wheel speed sensor 1 and pulser ring 3 may also be provided on the front fork 103L.

[0014] The pulser ring 3 has a disk shape centered on the axle 112, and rotates together with the front wheels FW. The pulser ring 3 has a plurality of slits 3a arranged in a ring shape, and the wheel speed sensor 1 detects the slits. The amount of rotation of the front wheels FW can be calculated from the slit detection signal output from the wheel speed sensor 1, and this makes it possible to calculate the vehicle speed of the vehicle 100. The detection signal of the wheel speed sensor 1 is transmitted to a control unit and instruments (not shown) via a sensor cable 2.

[0015] A brake caliper 113 is provided on the rear side of the front fork 103R. A brake disc 114 is fixed to the right side of the front wheel FW. The brake caliper 113 clamps the brake disc 114 by hydraulic pressure of brake fluid supplied via a brake pipe 115. This allows a braking force to be applied to the front wheel FW. An intermediate portion of the sensor cable 2 is held by a hose clamp 116 together with the brake pipe 115. The hose clamp 116 is fixed to the front fork 103R via a bracket 117.

[0016] An exterior material 10 is provided at a longitudinal midpoint of the front fork 103R. In this embodiment, the exterior material 10 is a rectangular, plate-shaped reflector. The front fork 103R of this embodiment is an upright front fork with an upper tube as an inner tube and a lower tube as an outer tube, and the exterior material 10 is supported at the upper end of the lower tube. The exterior material 10 may be provided on both the front forks 103R and 103L.

[0017] In addition to Fig. 3, Fig. 4 and Fig. 5 are referenced. Fig. 4 is a detailed view of the configuration of the right side of the front wheel FW with the wheel speed sensor 1 and the sensor cable 2 removed. Fig. 5 is a perspective view of the front fork 103R from its midpoint to its lower end.

[0018] A mounting portion 20 to which the wheel speed sensor 1 is attached is provided at the lower end of the front fork 103R. The mounting portion 20 is formed integrally with the front fork 103R on the rear side thereof. The mounting portion 20 is a plate-shaped portion having an outer surface 20a on the outside in the D2 direction and an inner surface 20b on the inside. The wheel speed sensor 1 is disposed on the outer surface 20a. A screw hole 23 is formed through the mounting portion 20 in the D2 direction, and the wheel speed sensor 1 is fixed to the mounting portion 20 by a screw structure utilizing the screw hole 23. The mounting portion 20 also has a cylindrical portion 22 that protrudes inward in the D2 direction. The detection portion of the wheel speed sensor 1 is inserted into the cylindrical portion 22 and detects the slit 3a.

[0019] The mounting portion 20 also has an opening 21 between the outer surface 20a and the inner surface 20b. The opening 21 penetrates the mounting portion 20 in the direction D2, and in this embodiment, the opening 21 is a hole (window) with a closed periphery. However, the opening 21 may also be a notch. The sensor cable 2 is routed from the wheel speed sensor 1 on the outer surface 20a through the opening 21 to the inner surface 20b.

[0020] The mounting portion 20 is also formed integrally with a support portion 30. The support portion 30 is formed integrally with the front fork 103R on the rear side of the front fork 103R. Two bolts 31 spaced apart from each other in the vertical direction are inserted into the support portion 30, and the brake caliper 113 is fixed to the support portion 30 via a bracket 40 by the two bolts 31.

[0021] A recess 103a is formed in the front fork 103R near the boundary with the support part 30. The recess 103a is recessed outward in the D2 direction and extends along the longitudinal direction of the front fork 103R at a position between the mounting part 20 and the exterior material 10. The front edge of the recess 103a in the D1 direction forms a protrusion 103b that protrudes slightly inward in the D2 direction (towards the front wheel FW). An attachment part 25 is formed integrally with the front fork 103R at a midpoint (at the upper end of the lower tube). The exterior material 10 is fixed to the attachment part 25.

[0022] The routing of the sensor cable 2 will be described with reference to Fig. 6 to Fig. 8. Fig. 6 is an explanatory diagram of the routing of the sensor cable 2, showing the front fork 103R as viewed from the front wheel FW side. Fig. 7 is a cross-sectional view taken along line AA in Fig. 3, and Fig. 8 is a cross-sectional view taken along line BB in Fig. 7.

[0023] The sensor cable 2 is routed upward from the mounting portion 20 along the front fork 103R between the front fork 103R and the front wheel FW. More specifically, it is led out from the wheel speed sensor 1 attached to the mounting portion 20 through the opening 21 to the front wheel FW side. From there, it extends upward parallel to the longitudinal direction of the front fork 103R to the vicinity of the exterior material 10. Partway along the routing, the sensor cable 2 is routed along the recess 103a. The sensor cable 2 is routed so as to enter the recess 103a.

[0024] The sensor cable 2 then curves away from the front fork 103R, passes between the exterior material 10 and the front wheel FW, and is held by a hose clamp 116. The sensor cable 2 further extends from the hose clamp 116 toward instruments or a control unit.

[0025] As described above, in this embodiment, the sensor cable 2 is routed so as to pass between the front fork 103R and the front wheel FW. In a right side view of the vehicle 100, the sensor cable 2 is hidden behind the front fork 103R as shown in FIG. 3 and is therefore not noticeable. Furthermore, the portion of the sensor cable 2 that leaves the front fork 103R is also not noticeable because it is hidden behind the exterior material 10. Furthermore, once the sensor cable 2 passes through the exterior material 10, it is bundled together with the brake piping 115 by the hose clamp 116 and is therefore not noticeable.

[0026] The sensor cable 2 is also routed along the recess 103a, which makes it easy to position the sensor cable 2 relative to the front fork 103R. The recess 103a partially surrounds the sensor cable 2, protecting it from flying objects. Furthermore, the protrusion 103b prevents the sensor cable 2 from moving forward, enhancing the positioning effect, and also prevents flying objects from the front from reaching the sensor cable 2.

[0027] The sensor cable 2 is also routed outside (to the right) of the front fender 111 in the direction D2. The front fender 111 guards against dirt and pebbles kicked up by the front wheel FW, preventing them from reaching the sensor cable 2. The sensor cable 2 also passes at a position forward of the brake caliper 113 in the direction D1. The brake caliper 113 guards against flying objects coming from behind the sensor cable 2, preventing them from reaching the sensor cable 2. The sensor cable 2 also passes rearward of the center C of the front fork 103R in the direction D1 and outside (to the right) of the inner end IE of the front fork 103R in the direction D2. The front fork 103R guards against flying objects coming from in front of the sensor cable 2, preventing them from reaching the sensor cable 2.

[0028] <Other embodiments> A guard portion may be provided to protect the sensor cable 2. FIG. 9 is a schematic diagram (cross-sectional view of the lower tube) showing one example. The guard portion 103c is formed integrally with the front fork 103R. However, the guard portion 103c may be separate from the front fork 103R. The guard portion 103c is a plate-shaped member extending rearward in the direction D1 from the front fork 103R, and is positioned between the sensor cable 2 and the front wheel FW. The guard portion 103c and the front fork 103R surround the sensor cable 2 except for the rear, thereby improving the protection performance of the sensor cable 2.

[0029] The guard portion 103c is provided at a position between the mounting portion 20 and the exterior material 10, extending in the longitudinal direction of the front fork 103R, and the length of the extension can be designed appropriately. As an example, it can be provided within a range of the same length as the recessed portion 103a. The recessed portion 103a and the guard portion 103c can also be used together.

[0030] Figure 10 shows another example of the configuration of the guard portion that protects the sensor cable 2, and corresponds to the cross section taken along line BB in Figure 7. The bracket 40 is a plate-shaped member, and has a guard portion 40a on a part thereof. The guard portion 40a extends obliquely in the direction D1 facing the inner side surface (the side surface on the front wheel FW side) of the front fork 103R, particularly the recess 103a.

[0031] The sensor cable 2 is located between the guard portion 40a and the recess 103a. front wheel The guard portion 40a is located between the sensor cable 2 and the front fork 103R. The sensor cable 2 is surrounded by the guard portion 40a and the front fork 103R, and the performance of protecting the sensor cable 2 can be improved.
