Above two-wheeled in, as following, constitute tread portion 30,30.

About pedal (tread portion) 30,30 form the left-right symmetric shapes, extend along fore-and-aft direction, in an embodiment, as shown in Figure 4, overlook the shape that forms similar skis down.

Pedal 30 at first forwardly has navigating mate with tread portion 31 to the rear portion, the footrest for passenger portion 32 of conjointly rearward extending therewith is being set then continuously.That is pedal 30 links to each other, slips into chaufeur and constitutes with the footrest for passenger 32 of the upper/lower positions slightly of vehicle seat 19a by the footrest for driver 31 of front portion and with its rear end.The footrest for driver portion 31 of pedal 30 is by secondary pedal part (secondary tread portion) 31d formation of main pedal part (main tread portion) 31c with the weak point that is connected in its rear end of the elongation of front and back, edge.

Pedal 30,30 clips the back basifacial steering column cover 7a of portion of above-mentioned front shroud 7, hang over central floor panel cover 11 thereafter the bottom both sides with and subsequent the both sides of the front portion of back cover 18 be configured.

As Fig. 4 expressed, the lateral border of each tread portion 30 anterior 30a under overlooking was to overall width direction inside bend, and as Fig. 1,3 expressed, anterior 30a formed upward agley.

As Fig. 4 expressed, the width of pedal 30,30 was a maximum width with the bottom of the bending of each anterior 30a, and rearward to make width be that the direction of vehicle body line of centers C closely is formed slopely the 30b of lateral border portion towards overall width direction inboard with narrowing down successively.

As Fig. 5, shown in Figure 6, above left and right sides pedal 30,30 in about clip ground such as central floor panel cover 11 and be configured.

The interior end edge portion 30c of pedal 30,30 is by accepting 11b, 11b supporting, and this carrier 11b, the outside side of 11b are located at the two side 11a of central floor panel cover 11, the bottom of 11a agley.The 30b of lateral border portion of pedal 30,30 is by upper end 12a, the 12a supporting of the both sides of end cover 12.

As Fig. 5, Fig. 6 expressed, pedal 30,30 was made of the face of inclination predetermined angular θ, its 30b of lateral border portion height, and 30c is lower than it in medial margin portion.That is pedal 30,30 is formed obliquely, and the overall width central side is lower than the outside, to overall width central side angulation θ to descending slope.

This inclination all is formed centrally downward gradient ground along pedal 30,30 and sets in vehicle body, in the footrest for driver portion 31 of Fig. 5, the footrest for passenger portion 32 of Fig. 6, this inclination is consistent.

For footrest for driver portion 31 and footrest for passenger portion 32, also can set different angle θ.

As Fig. 1, Fig. 3 expressed, the driver of pedal 30,30 tilted with tread portion 31, and anterior 31a height, rear portion 31b are low, up the gradient forward of angulation θ 1.Like this, for each footrest for driver portion 31 of tread portion 30,30, main pedal part 31c forms the gradient on the whole forward up.

Rear at the main pedal part 31c of above footrest for driver portion 31 forms secondary pedal part 31d continuously with it.Square neck tiltedly forms with heavy grade secondary pedal part 31d to make progress backward than above-mentioned angle θ 1 big angle θ 2 from low rear portion 31b.

In other words, main pedal part 31c forms with the dip plane, and its front portion (leading section) 31a is than rear portion (rearward end) 31b height.In addition, secondary pedal part 31d forms with the dip plane, and (the rear portion 31b of main pedal part 31c) is lower than rearward end 31e for its leading section.

The footrest for passenger portion 32 that is provided with continuously at the rear portion of the secondary pedal part 31d at the rear portion of footrest for driver portion 31, as shown in Figure 3, form to the descending slope crustal inclination with the square backward downwards one-tenth of angle θ 3 from the rearward end 31e of the secondary pedal part 31d of high position, be provided with to descending slope backward.

As Fig. 4 expresses, in pedal 30,30,, on the overall width direction, make the central side of the center P 1 more close vehicle body of footrest for passenger portion 32 with respect to the center P of the footrest for driver portion 31 that is arranged on front portion～rear middle part.

That is, as shown in Figure 4, the practical center P 1 of the footrest for passenger portion 32,32 about making, the distance L 1 between P1 (practical centre distance L1) less than about the practical center P, the distance L (practical centre distance L) between the P of footrest for driver portion 31,31.

Therefore, footrest for passenger portion 32,32 is disposed medially with respect to footrest for driver portion 31,31 deflection overall width directions.

" practical center P, P " refers to the common position of the practicality of chaufeur 40 placement pin 40a shown in Figure 7." practical center P 1, P1 " refers to that passenger 41 shown in Figure 7 places the common position of the practicality of pin 41a.

The footrest for passenger portion 32,32 of the pedal 30,30 about above-mentioned, in the both sides of the following quadrate part of the front portion of above-mentioned back cover 18 against the bottom of the rearward end both sides nearby of above-mentioned central floor panel cover 11.

About the both sides of this part of both sides, central floor panel cover 11 of back cover 18 at footrest for passenger portion 32,32 places, the recess 22,22 that slips into specified amount to the overall width inboard is set.That is, recess 22,22 is set in the both sides of main body cover 50.

As shown in Figure 6, the amount ground that sidewall 11a, the 11a of recess 22 about than central floor panel cover 11 slips into the width that for example is equivalent to call in person to overall width direction inboard forms, highly for example the bottom from middle base plate cover 11 is formed into the upper end, knee can be collected to the inside by bus.

Recess 22,22 outside to about the overall width direction is opened, and the part of recess 22 is shown by the oblique line of dotted line in Fig. 3, makes the locality specificization of the recess of side-looking.

In above situation, at first, about the overall width direction central side that carries instep of pedal 30,30 lower than the outside, form to descending slope to the vehicle body central side, as Fig. 5, as shown in Figure 6, under the state that passenger places pin 40a, 41a, pin 40a, 41a are all towards the inboard.For this reason, pin 40a, 41a on the pedal can make energetically, are difficult for outwards breakking away, and improve the retentivity of pin.

Because pin 40a, 41a all towards the inboard, move so pin 40a, 41a are difficult for outside side, can prevent that pin 40a, 41a from unconsciously jumping back out to the pedal outside.

The outer side height of pedal 30,30, the vehicle body central side is low, and therefore, the Outboard Sections of pedal uprises.As a result, the both sides that are disposed at the end cover 12 of pedal below also become the high position, therefore, can be provided with the two-wheeled angle that tilts when tilting bigger.

As Fig. 1, shown in Figure 3, footrest for driver portion 31 is by up forming the bevelled dip plane towards anterior direction, leading section height, rearward end are low, therefore, as shown in Figure 7, while taking a bus, the pin 40a of chaufeur 40 is placed on the anterior main pedal part 31c of bevelled dip plane up, and tiptoe becomes acclivitous state.

Therefore, as shown in Figure 7, even under the state with leg 40b elongation, tiptoe also becomes acclivitous posture, can improve the retentivity of pin 40a to pedal.For this reason, even elongated leg 40b also can remain on tiptoe on the main pedal part 31c, with comfortable posture, guarantee that the retentivity ground of pin uses walking always.

As shown in Figure 7 the workman by bus, at this moment, footrest for passenger portion 32 be up dip plane forward as described above, the tiptoe of passenger 41 pin 41a makes progress, and is placed in the footrest for passenger portion 32, similarly has good pin retentivity with above-mentioned footrest for driver 31.

The secondary tread portion 31d that is located at the main pedal part 31c rear portion of footrest for driver portion 31 tilts towards the rear portion direction is past as described above.

Therefore, as shown in Figure 8, pin 40a is being placed under the state of secondary pedal part 31d, pin forward down.As a result, two-wheeled 1 in service, when be rotated, turn to etc. turns to when walking, pin 40a becomes tiptoe and erects state, the bottom surface of pin 40a that comprises heel rearward applies power all forward toward having a down dip, pin 40a can make energetically secondary pedal part 31d.Therefore, favourable to rotating, turn to etc.

As Fig. 3, shown in Figure 6, both sides at the back cover 18 that comprises both sides, central floor panel cover 11 rear portion, part in the both sides that are positioned at footrest for passenger portion 32 forms the recess 22,22 (both sides in main body cover 50 form recess 22,22) that slips into overall width direction inboard.As shown in Figure 4, because the practical centre distance L1 of the footrest for passenger portion 32,32 about making is littler than the practical centre distance L of left and right sides footrest for driver portion 31,31, so compare footrest for driver 31,31, the inboard of footrest for passenger 32,32 more close overall width.

Therefore, passenger 41 pin 40a can not protrude into the outside as the footrest for driver of vehicle body lateral border.

Particularly because main body cover 50 sidepieces in footrest for passenger portion 32,32 inboards are provided with recess 22,22, so divisible formation front stall 19a and back seat 19b, form the leading section of back seat 19b particularly narrowly, passenger 41 the pin that comprises heel, the calf part that comprises leg 41b can rely in the recess 22,22 as shown in Figure 6.

As a result, passenger 41 need not open pin and use pedal, can ride under the state that tightens up pin 41a, leg 41b as far as possible to the inside, can obtain the pedal that women passenger likes.

Embodiment more than has been described, pedal 30,30 tilting to descending slope, is being provided with forward the gradient up to the vehicle body central side simultaneously, and, the rear portion of footrest for driver portion 31 secondary pedal part 31d is past backward to tilt, so, there is the danger of the surface area water of pedal 30,30.Therefore, for example, also can drain gutter be set, or constitute pedal with perforated panel, dictyosome with drainage in the part of pedal.

The present invention by above-mentioned consist of the performance following effect.

In the 1st invention, two-wheeled have low chassis turning between a section and the passenger Formula base plate, this base plate, will be stepped in this is two-wheeled take the vehicle-body width direction both sides as tread portion Board forms the overall width center side downward gradient lower than the outside, so, in the overall width direction of pedal Heart side is lower than the outside, and pin can be placed on the pedal to the inside.

Therefore, the pin that is placed on the pedal can make energetically, be difficult for sliding to the pedal outside, has improved pin Retentivity. In addition, because pin is all towards the inboard, so being difficult for outside side, moves on pin, thus can Jump the outside to pedal to prevent pin unconsciously.

Pedal is owing to outside portion height, vehicle body center side are low, so the Outboard Sections of pedal uprises configuration Cover both sides, the end below pedal also become the high position, can with two-wheeled when tilting about The inclination angle is set greatlyyer.

The 2nd invention is in the 1st invention, by in the main tread portion of front and back elongations be connected in its rear end The secondary tread portion of weak point consist of above-mentioned tread portion, simultaneously, this main tread portion by its front end than rearward end height The inclined plane form, and this pair tread portion is formed by the inclined plane lower than rearward end, its front end, Therefore, when the driver rides, when the main tread portion that pin is positioned over the inclined plane that the front portion is inclined upwardly When, because tiptoe is in forward toward the state that tilts, so even leg is stretched out, tiptoe is also Be forward toward the posture that tilts.

Therefore, the driver can stretch one's legs and take comfortable posture, and can guarantee that the retentivity ground of pin advances Row walking commonly used.

Be located at the secondary pedal at rear portion of main tread portion because towards the rear portion direction toward tilting, so with pin Be placed under the state of secondary tread portion, pin is downward forward, is easy to firmly can exert all one's effort, and it is right to obtain Two-wheeled rotation, favourable pedal when turning to walking when turning to etc.

In the 3rd invention, two-wheeled turn to have between a section and the passenger vehicle seat low Chassis type base plate, this base plate be take the vehicle-body width direction both sides as tread portion, in this is two-wheeled, By the footrest for driver of front portion be connected in its rear end and slightly slip into the driver with the passenger of below-seat Consist of above-mentioned tread portion with pedal, the practical centre-to-centre spacing that makes this left and right sides footrest for passenger is from less than an above-mentioned left side The practical centre-to-centre spacing of right footrest for driver from, so footrest for passenger is than footrest for driver more Near the inboard of overall width, passenger's pin can not protrude into the outside of footrest for driver.

Owing to be provided with at the sidepiece of the main body cover of passenger step inboard and slip into the recessed of overall width direction inboard Section can make in the recess of the leg bottoms such as the pin that comprises heel, calf and lean on. As a result, the passenger do not have must To open by force pin and use pedal, can receive inward knee, leg, pin ground by bus, can obtain the women and take advantage of The pedal that the visitor very likes.
