Between the two sides of limiting member 26, be provided with on direction of principal axis on pivot shaft 36 that the compartment of terrain is chimeric an a pair of ratchet 25.This ratchet 25 can rotate around pivot shaft 36 independently with limiting member 26.Ratchet 25 is the rearward outstanding claw 25A of fastening selectively on ratchet 24A that be formed with on the top of posterior edges.On ratchet 25, between the bottom surface of an opposite side with claw 25A, be provided with circular arc spring 38 at itself and housing 14, to ratchet 25 application of forces, its direction to claw 25A and ratchet 24A fastening is rotated.Between two ratchets 25, be equipped with release component 39 to be clamped in their middle modes.Release component 39 is entrenched on the pivot shaft 36, and is same with ratchet 25, can rotate around pivot shaft 36.On release component 39, be formed with slotted hole 40, and communication pin 34 fastenings that will give prominence to from the upper end of ratchet 25 are in the rearward end of slotted hole 40.Upper end at release component 39 is connected with the end that is connected the 3rd line 41 on the rear brake bar 28 via retracing spring 58, pulled by the spring force that makes the 3rd line 41 opposing retracing springs 58, thus by communication pin 34 incorporate release components 39 with ratchet 25 to the diagram anticlockwise motion, can be with the engagement releasing of claw 25A with the ratchet 24A of ratchet 25.
Base portion at the handle 43 (handle) of the end that is arranged on handlebar 42 is provided with metal bar installing department 44.On this bar installing department 44, be connected with the end of the cover panel of the 1st line 29 and the 3rd line 41, and rear brake bar 28 is installed to such an extent that can rotate around pin 45 is installed.Be connected with the end of the 1st line 29 at the base portion of rear brake bar 28.In addition, side is removed plate 46 being equipped with respect to the mode that installation pin 45 freely rotates below the base portion of rear brake bar 28, and links the end that the 3rd line 41 is arranged on releasing plate 46.
And then, on the base portion of rear brake bar 28, be provided with can pressing operation disengage button 47, have not shown fastening axle below.Removing on the plate 46, relatively have not shown fastening hole with the lower end of the fastening axle of disengage button 47, when the state (state of Fig. 8 (a)) at the operation rear brake bar 28 of not holding with a firm grip descends pressing operation disengage button 47, the top of the fastening axle of disengage button 47 enters the fastening hole, when under this state, holding operation rear brake bar 28 with a firm grip, remove plate 46 and rotate around pin 45 is installed in linkage, pull operation the 1st, the 3rd line 29,41 (state of Fig. 8 (c)) thus together with rear brake bar 28.Relative therewith, if rear brake bar 28 is not held on pressing operation disengage button 47 ground, the fastening axle of then removing plate 46 and disengage button 47 is non-fastening state, even operation rear brake bar 28 so hold with a firm grip, remove also invariant position of plate 46, therefore only pull operation the 1st line 29 (state of Fig. 8 (b)).
Clipping the relative position of limiting member 26 along the overall width direction at the outer peripheral face of axial region 16, the radius vector direction outside (roughly the place ahead) is outstanding to be equipped with a pair of bar sheet 48.On the other hand, be formed with a pair of hold-down arm 49 in that the central portion of the antetheca of housing 14 is forwards outstanding.Be connected with cylinder 50 (oil damper, oil-pressure damper, oil damper) between two hold-down arms 49 and cooresponding bar sheet 48, this cylinder has power fluid in the inside envelope, has the bar 61 that can stretch.A side end of two cylinders 50 (toe lateral end) is connected to such an extent that can rotate with respect to the front end of hold-down arm 49, and bar side end (rear portion side end) is connected to such an extent that can rotate with respect to the top of bar sheet 48.Two cylinders 50 are arranged side by side on the overall width direction, and dispose along the vehicle fore-and-aft direction respectively.But though two cylinders 50 are outstanding to the place ahead of housing 14, the top of two cylinders 50 do not given prominence to from the upper limb of housing 14, covers not shown shell with obstruction free on housing 14.
Two cylinders 50 work as compression spring, and only are constituted as carry out attenuation when elongation.Cylinder 50 constitutes switching mechanism T, can be boundary with the center position (state of Fig. 6) on the axis that is centered close to cylinder of turning cylinder 16A (axis that hold-down arm 49 sides and bar sheet 48 side both sides' coupling end is linked), carry out the application of force and make pin body 15 to reception position side displacement (moving) or make pin body 15 rotate on the contrary to the earthing position side.
Under the state that ratchet 25 and the fastening of the ratchet 24A of ratchet 24 are removed, the pin body 15 that is in earthing position is described being used for to the structure of reception position displacement.
On the position of the ratio overall width direction line of centers more close one-sided (driver's right crus of diaphragm side) of stretcher 9, dispose pedal 51.That is, as shown in Figure 2, as the car body main body 8 of leg fender for fear of with the interference of pipe 3 down, the overall width direction central portion of back rearward bloats and forms protrusion 8A, pedal 51 is configured in the position of deflection right crus of diaphragm side with respect to this protrusion 8A.This pedal 51 as shown in Figure 4, when pin body 15 is in earthing position (position shown in the long and two-short dash line), top pedal face 51A is positioned at by the top opening 52 that is formed on stretcher 9 outstanding upward position (with reference to the state shown in the long and two-short dash line), and when pin body 15 is in reception position (position shown in the solid line), pedal face 51A is chimeric with the state roughly very close to each other around with respect to opening 52, with top substantially flush (state shown in the solid line) of stretcher 9.In addition, on stretcher 9 on, clip the two side areas of the overall width direction of protrusion 8A, the part of putting pin zone F when constituting the driver and placing pin usually, and as shown in Figure 2, pedal face 51A is configured in this and puts in the F of pin zone.
In addition, as shown in phantom in Figure 1, when pin body 15 was in earthing position, pedal face 51A was configured to position, its rear end and leaves preset distance from the front edge of vehicle seat 11 to vehicle front.And then as shown in Figure 2, when pin body 15 was in reception position, pedal face 51A was configured to its front edge and rearward leaves preset distance from the back of leg fender (car body main body 8).
Below pedal face 51A, rearward be extended with and form circular-arc arm 53.On the other hand, can be supported with pedal axle 54 rotationally along the overall width direction below the installation portion 14B of one-sided (the disposing pedal 51 1 sides) of housing 14, the rear end of arm 53 is attached near the end in the overall width direction outside of pedal axle 54.Pedal axle 54 is compared the outside that is positioned at the overall width direction with turning cylinder 16A shown in Fig. 3 etc.Specifically, the medial end of pedal axle 54 (left end) on the birds-eye view on the overall width direction with the right-hand end position consistency of turning cylinder 16A.End in the overall width direction inboard of pedal axle 54, the radius vector direction outside are fixed with the distolateral of union lever 59.Another of union lever 59 be distolateral to be attached at and roughly to form the distolateral of circular-arc connecting strap 55, and another of this connecting strap 55 be distolateral to be attached near a side the rearward end of outside of armite 17 of pin body 15.Like this, pin body 15 can move displacement in linkage with the displacement of pedal 51.
In addition, be provided with pin body position detector switch 56 in the end in the overall width direction outside of the installation portion 14B of housing 14.On the other hand, pressing plate 57 is installed, thereby when trampling pedal 51 pin bodies 15 and be positioned at reception position, presses presser feet body position detector switch 56 by pressing plate 57 in the outside of the rearward end of the arm 53 of pedal 51.This pin body position detector switch 56 is assembled in the control circuit of driving engine E in this embodiment.Control setup is set for based on controlling from the having or not of signal of pin body position detector switch 56, allows the rotating speed of driving engine E to improve when pin body 15 is positioned at reception position, but forbids that when being in earthing position the rotating speed of driving engine E improves.
Next, specify the action effect of the present embodiment that constitutes like that as mentioned above.As shown in Figure 5, be positioned at pin body 15 under the state of reception position, thereby slide roller 37 fastenings of limiting member 26 are in the state of the rotation that stops ratchet 24 in the fastening recess 24B of ratchet 24, so pin body 15 can not rotate to earthing position because of not noting in vehicle '.When pin body 15 was positioned at reception position, shown in solid line among Fig. 4, the pedal face 51A of pedal 51 was in the top substantially flush state with stretcher 9, becomes the obstacle of driving so pedal 51 can not become useless thrust.
When pin body 15 is descended, make under the front and back wheel connected to chassis state, do not carry out the operation of holding with a firm grip of carrying out rear brake bar 28 of disengage button 47 with pushing.So the 1st line 29 is pulled, so limiting member 26 is the anticlockwise motion of middle mind-set Fig. 5 via bar side relaying member 30 with pivot shaft 36.Thus, limiting member 26 becomes the posture (Fig. 6 state) that vertical roughly stands up (straight) from the hypsokinesis posture.So slide roller 37 breaks away from from the fastening recess 24B of ratchet 24, so ratchet 24 becomes the state of liberating from the limit rotation of being undertaken by limiting member 26.
Under this state, the driver pin is rested on the protrusion 23 of pin body 15 and pin body 15 integral body are pedaled following time to earthing position, with the displacement of pin body 15 ground that links, ratchet 24 clockwise rotates as shown in Figure 6.During this period, slide roller 37 breaks away from fastening recess 24B and slides onto on the neighboring of ratchet 24.Become when standing up posture at limiting member 26, the 2nd line 35 is forwards pulled.The not shown interior spring of post brake device of this pulling opposing carries out, so limiting member 26 loads application force by this spring force to the diagram clockwise direction, so slide roller 37 is maintained the state on the neighboring that is pressed against ratchet 24.In when operation of holding with a firm grip when under this state, stopping, on bar side relaying member 30, act on rearward pressing force by retracing spring 32 to rear brake bar 28.Thus, the binding pin 27 of limiting member 26 moves to front in slotted hole 31, and bar side relaying member 30 rearward moves thus, so the 1st line 29 is pulled to the rear, and its result, rear brake bar 28 resets to the preoperative original position of holding with a firm grip.
On the other hand, pin body 15 to earthing position rotate during in, be accompanied by the rotation of an axial region 16, bar sheet 48 is center and rotating in linkage with turning cylinder 16A also.Therefore, shunk lentamente from the first-half period inner casing 50 of reception position during the earthing position rotation, so ratchet 24 and pin body 15 are replied loading force of displacement owing to cylinder 50 is subjected to making their to the reception position side at pin body 15.Therefore, if interrupt in operating in during this period under the pedaling with pin body 15, then ratchet 24 and pin body 15 automatically return to reception position owing to the loading force of cylinder 50.
Then, rotation at pin body 15 carries out, when surpassing the axis and the bar sheet 48 of cylinder 50 and being listed in center position (state shown in Figure 6) on the same straight line, the loading force that is produced by cylinder 50 is with above-mentioned opposite, with the mode effect that ratchet 24 is loaded to clockwise direction, so operation under the pedaling of pin body 15 is got final product with lighter power, interrupt halfway even pedal down operation in addition, pin body 15 is also accepted the loading force of cylinder 50 and is automatically rotated (with reference to Fig. 7) to earthing position.Before the top ends of pin body 15 at once will ground connection, ratchet 25 meshed gradually with the ratchet 24A of ratchet 24, and at the top ends connected to chassis of pin body 15 constantly, the ingear of ratchet 24A and ratchet 25 stops, and keeps both fastening states.Like this, limited ratchet 24 and pin body 15 and replied displacement to the direction of reception position, thus the leg 20 that vehicle integral body is supported for pin body 15 connected to chassis state together, and be in the state of left and right sides balance.In addition, when pin body 15 was in ground state, limiting member 26 was retained as the posture of standing up as mentioned above, and the 2nd line 35 is retained as the state that is pulled, so rear brake is retained as mode of operation.Therefore, even make vehicle parking in down-hill way, vehicle can not move because of not noting yet.
Operation is many under the pedaling of above-mentioned pin body 15 carries out under the driver is sitting in state on the vehicle seat.Therefore, even the top ends ground connection of state leftover bits and pieces body 15 of taking one's seat, when the driver leaves from vehicle seat 11, bumper (shock absorber) (not shown) thus lift on the elongation pin body 15.Therefore, the top ends that can produce pin body 15 is temporarily from the state of ground plane come-up, but since this moment also by the loading force of cylinder 50 make ratchet 24 further rotations pin body 15 is rotated downwards, so automatically correct to ground state.
If to pin body 15 is described from the action of earthing position when reception position resets, at first the disengage button 47 with rear brake bar 28 is pressed into.Thus, the fastening axle (not shown) of disengage button 47 enters the fastening hole (not shown) of removing plate 46 and fastening, so if hold operation rear brake bar 28 with a firm grip, ground therewith then links, remove plate 46 and also rotate, so the 1st, the 3rd line 29,41 is pulled together around pin 45 is installed.So bar side relaying member 30 forwards moves, but only link pin 27 this moment from the leading section of slotted hole 31 end side shifting backward, limiting member 26 can not move.On the other hand, because the pulling of the 3rd line 41 forwards furthers ratchet 25,, allow the anti-clockwise of ratchet 24 to rotate so the engagement of claw 25A and ratchet 24A is disengaged.
On the other hand, when pin body 15 was in earthing position, pedal 51 was in state outstanding above stretcher 9.At this moment, as shown in Figure 7, become and make pedal face 51A towards oblique posterosuperior posture.Under the state of the rotation of above-mentioned permission ratchet 24, promptly one side pressing operation disengage button 47 is held with a firm grip on one side and is operated under the state of rear brake bar 28, the driver is by trampling pedal face 51A, make on the pin body 15 and lift, pedal face 51A is being trampled when flushing above the stretcher 9, pin body 15 resets to reception position.In this period, the slide roller 37 of limiting member 26 is constantly slided on the outer peripheral face of ratchet 24, can not rotate to the earthing position direction thereby fall into fastening recess 24B ratchet 24 in the moment that arrives fastening recess 24B.When pin body 15 reset to reception position, the armite 17 of pin body 15 touched by being installed in touching on the member 19 that elastomeric material on the housing 14 constitutes, so the impact can absorb pin body 15 reliably and reset the time.
Because pin body 15 resets to reception position, pressing plate 57 is pressed presser feet body position detector switch 56.Thus, from the control setup output detection signal of this switch 56, allow to improve the rotating speed of driving engine E to driving engine.On the contrary, when pin body 15 was in earthing position, parking lighted and makes the driver to perceive 15 declines of pin body with lamp, even and the maloperation throttle gate, the rotating speed of driving engine E does not improve yet.
As mentioned above, according to present embodiment, pin body 15 and ratchet 24 common turning cylinder 16A that use as unidirectional mechanism so compare with the situation of structure on they being arranged on different axles, can reduce the size of the vehicle fore-and-aft direction of holder device.
From above-mentioned embodiment, can and then find following distinctive structure.
(1) the unidirectional R of mechanism that is made of ratchet device comprises: constitute the 1st rotation section and have the ratchet 24 of a plurality of tooth 24A of portion and with the mode that can the remove ratchet 25 with respect to the 24A of tooth portion fastening on side face.
If such structure, then when pin body 15 will be to the displacement of earthing position direction, be accompanied by the rotation of pin body 15, ratchet 25 changes catch positions gradually with respect to the ratchet 24A of ratchet 24, can make pin body 15 arrive earthing positions thus.But when pin body 15 will be to the displacement of reception position direction, ratchet 25 remained on initial catch positions with the ratchet 24A of ratchet 24, does not move to the reception position direction because do not note so limited pin body 15.
(2) the 1st rotation sections 24 are the structure of rotating synchronously with pin body 15.Here, so-called " rotating synchronously ", be not limited only to the form same with present embodiment, promptly ratchet 24 be installed on the axial region 16 by welding with pin body 15 integrated and rotate integratedly thus, though also comprise the form that does not have integrated mode of rotating to link with constant speed.
