DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a footrest structure for a vehicle, particularly a vehicle suitable for a scooter type motorcycle.

[0002]

2. Description of the Related Art For example, Japanese Patent Application Laid-Open No. 2000-142529.
FIG. 3 of the publication "Motorcycle" shows a motorcycle 1 in which a footboard 4 is arranged between a front wheel 2 (reference numerals are diverted from those in the publication; the same applies hereinafter) and a rear wheel 3. .
As shown in FIG. 4 of the publication, an occupant 5 who sits on or leans on the waist support member 21 shallowly can put his foot on the foot board 4.

[0003]

In many cases, the occupant 5 changes the position of the foot on the foot board 4 when the occupant sits deeply on the lumbar support member 21 or when the occupant sits shallowly. The footrest position also changes depending on the physique of the occupant 5, particularly the height of the occupant. In order to respond to such a request,
In a low-floor motorcycle, it can be said that flat steps extend back and forth.

[0004] However, depending on the preference of a small occupant or a driver, it may be desirable to take a riding posture that extends forward without bending the legs very much. In order to meet this demand, it is conceivable to integrally form a step portion at the front of a flat step floor (foot board). That is, the step floor is stepped. A stepped floor is, of course, more complex than a flat step floor. In order to maintain the required rigidity, the stairs are heavily weighted to provide reinforcement and the like, thereby increasing the manufacturing cost as compared with a flat step floor. Therefore,
The object of the present invention is to reduce the cost of the step floor,
An object of the present invention is to provide a vehicle footrest structure to which a footrest function having a high degree of freedom in a riding posture can be added.

[0005]

In order to achieve the above object, a first aspect of the present invention provides a main pipe extending rearward from a head pipe, an inclined section extending obliquely downward from the head pipe,
And a horizontal portion extending horizontally from the rear end of the inclined portion to support the step floor, wherein a step means is provided on the inclined portion of the main pipe at a position above the step floor.

[0006] The vehicle has a step floor and step means. Thereby, the driver can select the step floor and the step means and place the foot on the step. Since the step means is arranged separately from the step floor, it is not necessary to specially modify the step floor, and it is possible to suppress an increase in the manufacturing cost of the step floor.

According to a second aspect of the present invention, the step floor comprises a cover member disposed above the horizontal portion of the main pipe, and step floor boards provided on both sides of the cover member. By dividing the step floor board on which the feet are directly placed from the cover member on which the feet are hardly placed, it is easy to give a difference in the material or to give a difference in the shape.

According to a third aspect of the present invention, the rigidity of the step floor board is higher than the rigidity of the cover member. Increase the rigidity of the step floor board to deal with foot placement.

According to a fourth aspect of the present invention, the step floor is extended downward and forward of the step means. By extending the step floor to the lower front of the step means, it is possible to insert a toe as possible of the step means,
Expand the floor area of the step floor.

[0010] According to a fifth aspect of the present invention, the step means is a metal rod protruding from the inclined portion to the left and right substantially horizontally. By making the step means a simple metal rod, the manufacturing cost of the step means is suppressed.

According to a sixth aspect of the present invention, the seat provided in the vehicle has a structure in which the position can be adjusted in the longitudinal direction of the vehicle body and / or a structure in which the seat surface angle can be adjusted. By making the seat movable in the front-rear direction of the vehicle body, it is possible to correspond to the physique and preference of the driver. In addition, by providing the seat in a tiltable manner on the vehicle body, it is possible to operate not only in a sitting posture but also in a standing posture.

[0012]
