International Publication No. WO 2013/140891

However, in the configuration of Patent Document 1, the clamp member that supports the front wheel brake hose to the vehicle body is exposed to the outside, which reduces the vehicle's appearance.

The object of the present invention is to provide a saddle-type vehicle that solves the problems of the conventional technology described above and makes it difficult to see from the outside the clamp member that supports the front wheel brake hose on the vehicle body.

To achieve the above object, the present invention has a first feature in that a saddle-type vehicle (1) having a license plate (41) on the front side of the vehicle body is provided with a clamp member (60) for supporting a front wheel brake hose (70) on the vehicle body, and the clamp member (60) is disposed behind the license plate (41) and in a position overlapping the license plate (41) when viewed from the front of the vehicle body.

The second feature of the vehicle is that it is equipped with a pair of left and right front forks (3) that support the front wheel (WF) and a bottom bridge (5) that connects the left and right front forks (3). A stay (50) that supports the license plate (41) is fixed to the bottom bridge (5). The bottom bridge (5) is provided with a plurality of pedestals (5b, 5c) for fixing the stay (50). The clamp member (60) is fastened together with the stay (50) to one of the plurality of pedestals (5b, 5c). The pedestal (5c) that fastens together the clamp member (60) is thinner than the other pedestals (5b).

The third feature is that a positioning protrusion (5e) that prevents the clamp member (60) from rotating is provided at the vehicle width direction outer end of the base (5c) that fastens the clamp member (60) together, and the positioning protrusion (5e) is disposed outside the vehicle width direction outer end (50a) of the stay (50).

Furthermore, the fourth feature is that the clamp member (60) is formed of a plate-like member, and the height dimension of the positioning protrusion (5e) is greater than the thickness dimension of the clamp member (60).

According to the first feature, a saddle-type vehicle (1) having a license plate (41) on the front side of the vehicle body is provided with a clamp member (60) for supporting a front wheel brake hose (70) on the vehicle body, and the clamp member (60) is disposed behind the license plate (41) and in a position overlapping the license plate (41) when viewed from the front of the vehicle body. Therefore, when the saddle-type vehicle is viewed from the front, the clamp member supporting the front wheel brake hose is hidden by the license plate, making it possible to improve the appearance of the saddle-type vehicle.

According to the second feature, the vehicle includes a pair of left and right front forks (3) that support a front wheel (WF) and a bottom bridge (5) that connects the left and right front forks (3). A stay (50) that supports the license plate (41) is fixed to the bottom bridge (5). The bottom bridge (5) is provided with a plurality of pedestals (5b, 5c) for fixing the stay (50). The clamp member (60) is fastened together with the stay (50) to one of the plurality of pedestals (5b, 5c). The pedestal (5c) that fastens the clamp member (60) together is thinner than the other pedestal (5b). This eliminates the need for a dedicated fastening member for fastening the clamp member to the bottom bridge, and makes it possible to reduce the number of parts. In addition, by making one pedestal thinner in consideration of the thickness of the clamp member, the parallel arrangement of the license plate can be maintained even when the clamp member is fastened together.

According to the third feature, a positioning protrusion (5e) that prevents the clamp member (60) from rotating is provided at the vehicle width direction outer end of the base (5c) that fastens the clamp member (60) together, and the positioning protrusion (5e) is disposed outside the vehicle width direction outer end (50a) of the stay (50), so that it is possible to ensure sufficient height of the positioning protrusion without interfering with the stay. This makes it easier to fasten the stay and clamp member together.

According to the fourth feature, the clamp member (60) is formed of a plate-like member, and the height dimension of the positioning protrusion (5e) is greater than the thickness dimension of the clamp member (60), making it easier to tighten and fix the stay and clamp member together, and the positioning protrusion can reliably prevent the clamp member from rotating.

A preferred embodiment of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a right side view of a motorcycle 1 according to this embodiment. The motorcycle 1 is a saddle-type vehicle that travels by transmitting the driving force of a power unit P to a rear wheel WR via a drive chain (not shown). A steering stem (not shown) is rotatably supported on a head pipe F1 provided at the front end of the body frame F. A top bridge 8 is fixed to the upper end of the steering stem, and a bottom bridge 5 is fixed to the lower end of the steering stem. A pair of left and right front forks 3 are supported by the top bridge 8 and the bottom bridge 5. A front wheel WF is rotatably supported on the lower end of the front forks 3 by an axle 26.

A front fender 2 that covers the upper part of the front wheel WF is attached to the front fork 3 by a pair of left and right fender stays 24 and a second fender stay 25. A cylindrical fork cover 4 that covers part of the front fork 3 is attached to the bottom bridge 5.

A steering handle 11 for steering the front wheels WF is fixed to the top of the top bridge 8, and a pair of left and right rearview mirrors 10 are attached to the steering handle 11. A meter device 9, a headlight 7, and a pair of left and right front flasher lamps 6 are disposed in front of the head pipe F1.

The body frame F has a main frame F2 that extends downward and rearward from the head pipe F1. A rear frame F3 that supports a front seat 13 and a rear seat 14 is connected to the rear of the main frame F2. A pivot 22 that supports a swing arm 21 so that it can swing freely is disposed at the lower rear part of the main frame F2. An axle 20 that supports the rear wheel WR so that it can rotate freely is disposed at the rear end of the swing arm 21. The rear part of the swing arm 21 is suspended from the rear frame F3 by a pair of left and right rear cushions 15.

A power unit P, which is an integrated engine and transmission, is suspended below the main frame F2 and in front of the pivot 22. Combustion gas from the power unit P is led via an exhaust pipe 23 to a muffler 19 located at the rear of the vehicle body. A fuel tank 12, which straddles the main frame F2 in the center of the vehicle width direction, is located above the power unit P. A taillight unit 17 and a pair of left and right rear flasher lamps 18 are attached to the rear of a rear fender 16 that covers the upper part of the rear wheel WR.

Figure 2 is a partially enlarged front view of motorcycle 1. Figure 3 is a partially enlarged plan view of motorcycle 1, and Figure 4 is a partially enlarged view of Figure 3. The same reference numerals as those above indicate the same or equivalent parts. A horizontally long rectangular license plate 41 is disposed in front of the front fork 3 of motorcycle 1. The license plate 41 is supported by a stay 50 (shown in gray) fixed to the front surface of the bottom bridge 5. A front wheel brake hose 70 for operating the front wheel brake is routed near the bottom bridge 5. The front wheel brake hose 70 extends from the steering handle 11 on the right side in the vehicle width direction, passes behind the headlight 7 and the bottom bridge 5, and is routed downward.

Referring to FIG. 4, the stay 50, which is made of a thin metal plate member, is fixed to the front surface of the bottom bridge 5 by a fastening member 51 consisting of two bolts or the like. A clamp member 60 that supports a front wheel brake hose 70 is disposed behind the stay 50, at a position toward the left in the vehicle width direction. The clamp member 60 is fastened together with the stay 50 to the front surface of the bottom bridge 5 by the fastening member 51 on the left side in the vehicle width direction. As a result, when the motorcycle 1 is viewed from the front, the clamp member 60 is hidden by the license plate 41, and the clamp member 60 is not exposed to the outside, improving the appearance.

Figure 5 is a perspective view of the bottom bridge 5 as viewed from below, front, on the right. Figure 6 is an enlarged perspective view of the bottom bridge 5 as viewed from below, front, on the right, and Figure 7 is a perspective view of the bottom bridge 5 as viewed from below, front. Figure 5 shows the front wheel brake hose 70 and harness 71 held by the clamp member 60 (shown in dotted hatching), and Figures 6 and 7 show the state in which only the clamp member 60 is fixed to the bottom bridge 5.

The clamp member 60, which is formed by pressing a single metal plate, has a main body 61 made of two overlapping metal plates, a large diameter portion 62 that holds a first grommet 72 through which the front wheel brake hose 70 is inserted, a small diameter portion 63 that holds a second grommet 73 through which the harness 71 is inserted, and a stopper portion 64 that functions as a rotation stopper for the clamp member 60. The main body 61 extends downward from the fastening portion formed by the fastening member 51, curves backward toward the bottom bridge 5 below, and then extends inward in the vehicle width direction to connect with the large diameter portion 62 and the small diameter portion 63.

The front wheel brake hose 70 and harness 71 supported by the clamp member 60 are routed with a large curve that convexly curves forward, but because the clamp member 60 and its surroundings are hidden by the license plate 41, there is no impact on the appearance.

Figure 8 is a partially enlarged view of the bottom bridge 5. Figure 9 is a plan view showing the co-fastening structure of the clamp member 60. On the front surface of the bottom bridge 5, pedestals 5b and 5c are formed as raised flat surfaces for fixing the stay 50. In the center of the pedestals 5b and 5c, female threaded holes 5a into which the fastening member 51 screws are provided.

The clamp member 60 is fastened together with the base 5c on the left side in the vehicle width direction. This eliminates the need for a dedicated fastening member for fastening the clamp member 60 to the bottom bridge 5, making it possible to reduce the number of parts. The outer end of the base 5c in the vehicle width direction is provided with a positioning protrusion 5e that forms a linear erected wall 5d. When fastening together the clamp member 60, the clamp member 60 is positioned so that the abutment portion 64 faces the erected wall 5d of the base 5c, and the fastening member 51 is screwed in.

In this embodiment, the thickness of base 5c is made thinner than base 5b, taking into account the thickness of clamp member 60. This allows the license plate 41 to be kept parallel even when clamp member 60 is fastened together. In addition, positioning protrusion 5e is disposed outside outer end 50a of stay 50 in the vehicle width direction. This makes it possible to ensure sufficient height for positioning protrusion 5e without interfering with stay 50, making it easier to fasten stay 50 and clamp member 60 together.

Furthermore, in this embodiment, the height dimension of the positioning protrusion 5e is set to be greater than the thickness dimension of the clamp member 60. This makes it easier to fasten the stay 50 and the clamp member 60 together, and the positioning protrusion 5e can reliably prevent the clamp member 60 from rotating.

As described above, the saddle-type vehicle of the present invention is provided with a clamp member for supporting the front wheel brake hose on the vehicle body, and the clamp member is disposed behind the license plate and overlaps the license plate when viewed from the front of the vehicle body. Therefore, when the saddle-type vehicle is viewed from the front, the clamp member supporting the front wheel brake hose is hidden by the license plate, which makes it possible to improve the appearance of the saddle-type vehicle.

The shape of the motorcycle, the shape and structure of the bottom bridge, the shape and arrangement of the license plate, the shape and structure of the stays and clamp members, the type of hoses held by the clamp members, etc. are not limited to the above embodiment and can be modified in various ways. For example, the clamp member supporting the front wheel brake hose may be disposed in a position shifted to the right in the vehicle width direction. The mounting structure of the clamp member according to the present invention is not limited to motorcycles, but can be applied to various straddle-type vehicles such as three-wheeled vehicles and four-wheeled vehicles.
