Description

Technical field of motorcycles

The present invention relates to a motorcycle including a tail light at a rear portion. Background technology>

Conventionally, there is a motorcycle in which a tail light is disposed at a rear portion and a tail cover is provided so as to cover the tail light (for example, Japanese Patent Application Laid-Open No. 2002-193610, Open 200-3—see 722624).

By the way, it is conceivable to increase the size of the te / relight in the motorcycle (hereinafter, also referred to as the “taillight width”) in order to increase the tenorrelight's perception. Increasing the width of the taillights makes it easier for riders on the following vehicles, such as dry cars and motorcycles, to see and recognize the tenoraire lights.

However, in a straddle-type motorcycle that has a fuel tank behind the steering wheel and a seat behind the fuel tank, if the width of the taillight is too wide, the tail cover that covers the taillight and cams will be in the direction of the arrow. And the rider's ease of getting on and off the motorcycle deteriorates. For example, when a rider raises his foot and straddles a saddle-type motorcycle, it becomes a tail cover.

Also, if the width of the tenorelleite is too wide and the tenorelleite and the tenorelle cover protrude in the vehicle width direction, the aerodynamic performance of the motorcycle deteriorates.

The present invention has been made in view of a powerful situation, and an object of the present invention is to provide a motorcycle in which the rider's getting on and off f / c is delicate and the visibility of tenor light is improved. Invention disclosure>

According to the first aspect of the present invention, a steering shaft, a body frame extending from the disgusting steering shaft to the outside, a seat supported on the SiflB body frame, and a seat shaft between the Sift self-steering shaft and the tiff self seat are provided.燃料 A rear arm that supports the front wheel at the front end of the body frame and supports the rear wheel, and a tin arm that supports the tfriB rear arm to the tin body frame. A te / relight arranged on the vehicle body with a cushion, a brake light part and a win light part; and It has a tail cover that covers the upper end attached to the outside of the body frame of the lya cushion, and the ttft tail light in the 畐 direction is less than the minimum distance of the pair of lya cushions in the 嫌> 畐 direction. Motorcycles that are larger and smaller than the maximum dimension of the shuttle tank in the ¾> 畐 direction are »

The term “tail light” as used herein means a so-called combination light that is combined with the brake light portion and the blinker light portion.

The “minimum distance in the vertical direction between a pair of lya cushions” means the point closest to the lya cushion of one lya cushion and the point closest to the one lya cushion of the ite cushion. Means the interval. That is, the “minimum distance in the negative direction between a pair of lya cushions” means the distance between the inner edge of one lya cushion and the inner surface of the lya cushion.

“Maximum clearance in the direction of the fuel tank” means the width of the fuel tank at the point where the width of the fuel tank is the largest.

The maximum dimension of the fsf tank & body including the length is defined as the “maximum dimension of the fuel tank in the vehicle width direction”. I reckon. As an example of the “attachment of the shape along the outer shape of the fuel tank” here, air that is fixed to the fuel tank so that its surface is substantially flush with the surface of the fuel tank and covers part of the tank Guides. However, the phrase “Thanks for the shape along the outer shape of the fuel tank” is not limited to the shape of an air guide.

According to the motorcycle described above, it is possible to improve the visibility of the taillight while maintaining the rider's getting on and off 14 well. In other words, the width of the taillight is increased in a range where the taillight does not protrude from the fuel tank in the vehicle width direction, so that the visibility of the taillight and the life of the taillight can be improved without deteriorating rider getting on and off. In this way, the driver of the succeeding vehicle or the rider of the subsequent motorcycle can easily recognize the tenor relay.

Usually, the width of the fuel tank is set according to the characteristics of the vehicle. Auto: ^ Some cars have a fuel tank width of J: b ^ for ease of handling, depending on the main application, while others have a fuel tank width for easy handling by riders. Some are relatively wide The According to the motorcycle of the present invention, since the taillight does not protrude in the vehicle direction from the fuel tank, the rider can handle the motorcycle easily.

The rider straddles the motorcycle with the knee ^ the fuel tank across the motorcycle seat.

3 When the rider lifts one leg to straddle the motorcycle seat, if the taillight protrudes in the 畐 direction from the return tank, the rider's feet can easily hit the tail power bar covering the taillight feW ^.

According to the motorcycle of the present invention, the taillight does not protrude in the vehicle width direction from the fuel tank, so the rider can easily straddle the seat.

Also, when the rider lifts one foot up on the ground to get off the seat, if the taillight protrudes in the vehicle direction from the fuel tank, the tail canopy covering the left of the taillight; The feet of ifc ^ are easy to hit.

According to the motorcycle of the present invention, since the taillight does not protrude from the fuel tank in the bridle direction, the rider can easily get off the seat.

According to the motorcycle of the present invention, the aerodynamic performance of the motorcycle is good. If the taillight protrudes in the right direction from the tank, the aerodynamic resistance increases and the aerodynamic performance of the motorcycle is monitored. According to the motorcycle of the present invention, the taillight does not project from the fuel tank in the ¾> ¾ direction, and the tail canopy that covers the 畐 end of the taillight also covers the upper ends of the pair of rear cushions. As a result, air flows smoothly from the side to the rear of the motorcycle. .

Further, according to the motorcycle of the present invention, since the tail cover has a function of covering the tail light and a function of covering the rear of the reaction, the number of parts with cover sounds can be reduced.

According to the second aspect of the present invention, the tins tail light is disposed between the pair of win light lights, and the MIS brake light is protruded rearward from the touch win light light. It has a curved shape that protrudes backward in plan view, and at the boundary between the ftflB tail cover and the tail light, the surface of the tail cover is almost flush with the surface of the tin light part.

According to the above statement, the taillight force is curved and extended to the side of the motorcycle, so that the taillight brake light and the winlight light can be adjusted even from diagonally behind or from the side of the motorcycle. Easy to see. Therefore, the visibility of the taillight is further improved. According to the third aspect of the present invention, the tail light of the knitted tail light has a concave curved surface on the side;

According to the above, it is easy to see the win-carlit part of the motorcycle from one diagonally behind the motorcycle. Therefore, the visibility of tenorerite is further improved.

According to a fourth aspect of the present invention, the Yuki tail light is arranged with a brake light section S between a pair of win light sections, and the knitting brake light section is more wasteful than the Fujimi Win light section. The protruding seat has a curved shape protruding rearward in a plan view, and the vulgar seat has a main seat and a passenger seat disposed behind the main seat. It is located further back in the taillight direction.

According to Makoto Makoto, the passenger seats extend from the taillights of the cafeteria in the $ 1 畐 direction, and the passenger seats are large and comfortable. By increasing the size of the taillight in the 畐 direction, it became possible to provide such a large passenger seat. According to the above 3t Shigenari, it is possible to improve the visibility of the tenor seat while maintaining the rider's getting on and off I "life as a ^! Child, and further improve the sitting comfort of the passenger seat.

According to the fifth aspect of the present invention, the distance in the direction of the rear end of the vulgar passenger seat is greater than the minimum distance between the pair of lya cushions in the vehicle width direction, and Smaller than the maximum dimension of.
