As a conventional motorcycle, one having a disc brake device is known (for example, see Patent Document 1).
Japanese Utility Model Publication No. 60-60385

FIG. 2 of Patent Document 1 will be described with reference to FIG. In addition, the code | symbol was reassigned.
FIG. 16 is a side view of the main part showing the front part of a conventional motorcycle. A front wheel 302 is rotatably attached to the lower end of a front fork 301 provided at the front part of the motorcycle, and a rim constituting the front wheel 302 is shown. The outer peripheral portion of the disc plate 304 is attached to the side portion 303, and the caliper 307 is attached to the front fork 301 via the bracket 306 to brake the disc plate 304 from the inner peripheral portion side.

In the motorcycle, since the caliper 307 is moved away from the front axle 311 of the front wheel 302, the braking load generated by the caliper 307 can be small. That is, the rigidity of the front fork 301 that supports the caliper 307 can be lowered. If the front fork 301 can be reduced in weight while further improving the rigidity of the front fork 301, for example, the weight of a large displacement vehicle having a large output can be reduced.
Further, for example, if the front fork 301 is improved so as to give a new impression as an appearance, it can be made attractive as a motorcycle, and the merchantability is enhanced.

  An object of the present invention is to reduce the weight of a wheel support portion while ensuring the rigidity of a wheel support portion that supports a wheel in a motorcycle, to effectively use a space, and to improve merchantability.

According to the first aspect of the present invention, the outer peripheral portion of the annular brake disc is attached to the rim of the wheel, the brake caliper is attached to the wheel support portion that supports the wheel, and the brake disc is straddled from the inner peripheral portion of the brake disc. In a motorcycle equipped with a brake disc device that is sandwiched between the wheel support portion, the wheel support portion is provided with an opening portion that opens to the side of the vehicle, a brake caliper is attached to the wheel support portion so as to cross the opening portion, and the wheel is steered. The steering wheel is supported by a single long suspension , an opening is formed by the rim and the brake disc, and the brake caliper is bolted to the inner surface of the wheel support through the opening. It is characterized by being able to.

Since the brake caliper is mounted so as to cross the opening while providing an opening in the wheel support so that the appearance impact can be emphasized, the brake caliper can increase the rigidity of the wheel support. .
In addition, a brake caliper is disposed in the opening of the wheel support portion, and the space around the wheel support portion is effectively used. Further, it is possible to firmly receive and support the load applied during braking applied to the brake caliper.
Furthermore, an opening is provided in the wheel support portion to give a new impression as an appearance.
Still further, the steering wheel is supported by one long suspension device to form a slim vehicle body.
