Technical Field

[0001] This invention relates to a straddle-type vehicle. Background Technology

[0002] Patent Document 1 discloses a straddle-type vehicle. The straddle-type vehicle includes a body frame, a resin rear fender, rear wheels, and rear turn signals. The body frame includes a metal seat frame. The rear wheels are mounted to the body frame. The rear fender is mounted to the seat frame. The rear wheels are positioned below the seat frame. The rear turn signals are mounted to the rear fender.

[0003] Patent documents

[0004] Patent document 1: Japanese Patent Application Publication No. 2010-228553. Summary of the Invention

[0005] In conventional straddle-type vehicles, the rear fenders are made of resin, which may result in insufficient mounting strength of the rear turn signals relative to the fenders. Furthermore, since the rear turn signals are mounted on the rear fenders, mud and water splashed from the rear wheels during driving may adhere to them.

[0006] The object of this invention is to provide a straddle-type vehicle that can improve the installation strength of the rear turn signal. Another object of this invention is to provide a straddle-type vehicle that can prevent mud and water splashed from the rear wheels during driving from adhering to the rear turn signal.

[0007] One aspect of the present invention relates to a straddle-type vehicle comprising a body frame, rear wheels, a seat, a rear cover, and rear turn signals. The body frame includes a seat frame made of metal. The rear wheels are mounted to the body frame. The rear wheels are positioned below the seat frame. The seat is positioned above the seat frame. The rear cover is positioned below the seat frame. The rear cover is mounted to the seat frame. The rear turn signals are mounted between the seat and the rear cover within the seat frame.

[0008] In the straddle-type vehicle described in this method, the rear turn signal is mounted on a metal seat frame, thus increasing the mounting strength of the rear turn signal. Furthermore, in the straddle-type vehicle described in this method, since the seat frame is mounted between the seat and the rear grille, and this seat frame is positioned above the rear wheels, it is possible to prevent mud and water splashed from the rear wheels during driving from adhering to the rear turn signal.

[0009] When viewed from the side, the rear turn signal can also be positioned slightly above the lower end of the tailgate. This helps to effectively prevent mud and water splashed from the rear wheels during driving from adhering to the rear turn signal.

[0010] When viewed from the side, the rear turn signal can also be positioned further forward than the rear of the seat. This helps to effectively prevent mud and water splashed from the rear wheels during driving from adhering to the rear turn signal.

[0011] The straddle-type vehicle may also include taillights mounted on the rear grille. In this case, when viewed from the side, the rear turn signals are positioned further forward than the taillights. This helps to appropriately suppress mud and water splashed from the rear wheels during driving from adhering to the rear turn signals.

[0012] The rear turn signals may also include a pair of rear turn signals. In this case, when viewed from the rear, the taillights and the pair of rear turn signals are arranged in a left-right direction. Thus, the pair of rear turn signals are positioned higher than in the prior art, thereby improving the visibility of the rear turn signals.

[0013] The rear turn signal may also include a pair of rear turn signals. In this case, each pair of rear turn signals has a flashing part and a mounting part, which is connected to the flashing part and mounted on the seat frame. When viewed from behind, the flashing part is positioned further outward than the side of the seat. This appropriately improves the visibility of the rear turn signals.

[0014] The straddle-type vehicle may also include a metal strut that connects to the seat frame. In this case, when viewed from the side, the rear turn signal is mounted on the strut between the lower end of the seat and the lower end of the rear spoiler. This allows the rear turn signal to be easily mounted on the seat frame via the strut.

[0015] The rear turn signal may also have a flashing part and a mounting part connected to the flashing part. In this case, the support bar has a fixing part and a mounting part, the fixing part being fixed to the seat frame and the mounting part extending downward from the fixing part. The mounting part is installed on the mounting part. Thus, the rear turn signal can be easily mounted to the support bar from below the seat frame.

[0016] The vehicle frame may also have a center plane that passes through the head tube in the longitudinal direction. In this case, when viewed from the rear, the mounting part is positioned between the mounting part and the center plane. The mounting part is attached to the mounting part by fastening members positioned between the center plane and the mounting part. As a result, the fastening members are not exposed to the outside, thus improving the rust resistance of the fastening members and enhancing the design of the straddle-type vehicle.

[0017] The strut can also have a fixing part and a mounting part. The fixing part is fixed to the seat frame, and the mounting part extends downward from the fixing part and mounts the rear turn signal. In this case, at least a portion of the fixing part is covered by the seat. This improves the rust resistance of the strut.

[0018] The straddle-type vehicle may also include: a metal strut connected to the seat frame; and a resin side cover that covers the seat frame from the side. In this case, the strut is exposed when viewed from the side, not covered by the side cover. This allows the rear turn signal to be easily mounted on the seat frame via the strut.

[0019] According to the present invention, the mounting strength of the rear turn signal can be improved in a straddle-type vehicle. Furthermore, according to the present invention, mud and water splashed from the rear wheels during driving can be prevented from adhering to the rear turn signal. Attached Figure Description

For example, the fixing part 13a is fixed to the first seat frame 17b. Specifically, the fixing part 13a is fixed to the first seat frame 17b by means of welding or the like. Figure 4 and Figure 5 As shown, at least a portion of the fixing part 13a is covered by the seat 10. In this embodiment, as... Figure 5 As shown, the fixing part 13a is covered by the seat 10. The fixing part 13a may also be partially covered by the seat 10.

[0064] like Figure 3 and Figure 5As shown, a rear turn signal 4 is mounted on the mounting portion 13b. The mounting portion 13b extends downward from the fixing portion 13a. For example, with the fixing portion 13a fixed to the seat frame 17, the mounting portion 13b extends downward from the fixing portion 13a. The mounting portion 13b and the fixing portion 13a are integrally formed. Figure 4 As shown, a bolt hole 13c is formed in the mounting portion 13b. An externally threaded portion 4b1 (described later) is inserted into the bolt hole 13c. Figure 3 ).like Figure 5 As shown, in rear view, the mounting part 13b is positioned between the mounting part 4b of the rear turn signal 4 (described later) and the vehicle center plane H.
