Before and after each limiting wall 27, its left end is fixed on the right lateral surface of supporting walls 64, the right-hand member side of the limiting wall 27 of these front and back is by connecting wall 69 connections, this connecting wall 69 is overlooked circular-arc into to right-hand protrusion.

In this example, limiting wall 27 before and after these and connecting wall 69 are integrally formed by a sheet material is bent.

In addition, the upper surface of each limiting wall 27 forms, and skewed along with what be moved upward to right-hand advancing from left end, the soffit of each limiting wall 27 forms the approximate horizontal shape along left and right directions.Therefore, each limiting wall 27 form along with from left end to right-hand advancing and up and down width broaden gradually.

Left and right directions middle part at each limiting wall 27 of front and back is provided with the restricted guidance portion 49 of shaking.Therefore, swing the height of limiting wall 27 upper surfaces in the left side of restricted guidance portion 49 therewith and compare, the height of limiting wall 27 upper surfaces on the right side of swing restricted guidance portion 49 is higher.

In this 3rd example, from the neutral position to operating pedal 22 during in the 1st direction of operating A swinging operation, swing restricted guidance portion 49 is by inserting holding section 47, allow the swing of this holding section 47 and restriction the swinging of holding section 47 (promptly, this swing restricted guidance portion 49 swinging operation of allowing the 1st direction of operating A of operating pedal 22, and limit the swinging operation of the 2nd direction of operating B of operating pedal 22).

In addition, in the 3rd example, about swing restricted guidance portion 49 be relative shape at fore-and-aft direction, constitute by the groove (being referred to as slot 49) of the lengthwise of penetration state on the thickness direction of limiting wall 27 and open upward shape.

This slot 49 be tabular surface at left and right directions facing surfaces 49a along above-below direction, bottom surface 49b is the tabular surface along left and right directions.

Slot 49 become the restriction face 49a of restriction the swinging of holding section 47 (swinging of restriction operating pedal 22) at left and right directions facing surfaces 49a.

This swinging mounting axle 28 forms the tubular with left and right directions axle center, and its left part runs through the supporting walls 64 of support unit 24, and is fixed on this supporting walls 64.

In addition, this swinging mounting axle 28 is configured in the more left of slot 49, and the limiting wall 27 of the rear portion side of its right side part of the words that are set to overlook and front side is overlapped.

In addition, this swinging mounting axle 28 be configured in limiting wall 27 near, the lower end of this swinging mounting axle 28 is positioned at the more downside of limiting wall 27 upper surfaces on the right side of slot 49.

Described rocking bracket 25 is by constituting with lower member: plate faces the 1st flat board 71 of the lengthwise on the left side that is configured in supporting walls 64 to the left and right, to right-hand be fixed on with being standing shape the spindle unit 72 of the middle part up and down of this 1st flat board 71, rearward be arranged on with being standing shape described the 1st flat board 71 top the front portion the 2nd flat board 73, rearward be arranged on the cartridge unit 74 on the right side of this 2nd flat board 73 with being standing shape.

The top of described the 1st flat board 71 is configured to extend to the more top of supporting walls 64, and becomes the shape of extending by the opening that forms on foot pedal 63 above this foot pedal 63.

The middle part of the 1st flat board 71, become along with this middle part front end advance downwards and rearward shift skewed, and form that width narrows down gradually along with advancing downwards.

Described the 2nd flat board 73 is positioned near the top of foot pedal 63, gives prominence to right-hand from the 1st flat board 71, and crosses the upper side of supporting walls 64.

Described spindle unit 72 has the axle center X of left and right directions, rotates around axle center X and inserts logical being supported on the swinging mounting axle 28 freely.Thus, rocking bracket 25 is supported on the swinging mounting axle 28 freely around the axle center of left and right directions X (on the 1st direction of operating A) swing.

The cartridge unit 74 of rocking bracket 25 above the right part of swinging mounting axle 28 and be positioned at foot pedal 63 above, have the axle center Y of fore-and-aft direction.In addition, the axle center Y of this cartridge unit 74 is offset to the left side position from the top position of slot 49.

The top of pedal support component 23 is fixed with pivot 35 with forwards being standing shape, and this pivot 35 is inserted logical and is supported in this cartridge unit 74 freely around axle center Y rotation from the rear.Thus, pedal support component 23 is supported on the rocking bracket 25 freely around the axle center of fore-and-aft direction Y (on the 2nd direction of operating B) swing.

Pedal support component 23 is formed by long up and down sheet material, and top 23a is configured to plate and faces forwards, backwards, and above the central portion between the limiting wall 27, the lower end side of the top 23a of this pedal support component 23 becomes the shape of the lower side of inserting foot pedal 63.

The bottom 23b of this pedal support component 23 is configured to plate and faces forwards, backwards, is positioned at the rear of the limiting wall 27 of the lower side of foot pedal 63 and rear side.

In addition, the middle part 23c of the above-below direction of pedal support component 23 form from 23a lower end, top towards bottom 23b upper end and to the back lower place move skewed.

In addition, pedal support component 23 is configured in from the position of the formation position location skew left of slot 49.

The upper end of pedal support component 23 (the more upper side of pivot 35) is fixed with the support tube 43 in the axle center with left and right directions, and operating pedal 22 is supported on this support tube 43.Because the structure and the 1st example of this operating pedal 22 are roughly the same, therefore the identical parts identical symbol of mark is omitted explanation.

In addition, in this 3rd example, forwardly be pasted with anti-skidding thing 75 on the upper surface of pedal 41.

Lower end side at the 1st flat board 71 of described rocking bracket 25, be connected with to pivotal support inner cable one distolateral of the operation hawser (diagram is omitted) that constitutes by push-and-pull hawser etc., distolateral being installed on the described the 1st outer installation portion 67 of the outside hawser of this operation hawser.

In addition, another of the inner cable of this operation hawser is distolateral to be connected with the guiding valve accessory control valve, when from the neutral position during to the side of the 1st direction of operating A or opposite side (front and back) trampling operating pedal 22, the inner cable of the described operation hawser of push-and-pull and the accessory control valve is operated.

In addition, be formed with the hole 76 that usefulness is installed on supporting walls 64, use with a distolateral lower end side that is installed to the 1st flat board 71 of inner cable the time in this hole 76.

On the 23b of the bottom of pedal support component 23, be connected with the spherojoint 77a of the left end side of interlock link rod 77 from rear side.

On the other hand, the preceding bottom of the right flank of supporting walls 64 is fixed with Support bracket 78.On the right side of this Support bracket 78, to erect and be provided with bolster 79, this bolster 79 has the axle center of above-below direction.Relaying tube 80 rotates freely around the axle center, and overcoat is supported on this bolster 79.This relaying tube 80 is configured in the front side and the right side of the limiting wall 27 of front side.

Again, on the top of relaying tube 80, give prominence to be provided with the 1st relaying bar 81 towards the right back, and the 1st relaying bar 81 crosses the right-hand side of limiting wall 27, outstanding distolateral at this 1st relaying bar 81 is connected with the spherojoint 77b of the right-hand member side of described interlock link rod 77 from upper side.

Again, in the bottom of relaying tube 80, towards the left front side give prominence to and be provided with the 2nd relaying bar 82.

Outstanding distolateral at this 2nd relaying bar 82, be connected with to pivotal support inner cable 83a one distolateral of the operation hawser 83 (diagram is omitted) that constitutes by push-and-pull hawser etc., distolateral being installed on the described the 2nd outer installation portion 68 of the outside hawser 83b of this operation hawser 83.

Again, another of the inner cable 83a of this operation hawser 83 is distolateral, the guiding valve of swing control valve is connected, when from the neutral position to the side of the 2nd direction of operating B or opposite side (about) during trampling operating pedal 22, push-and-pull interlock link rod 77 and inner cable 83a by the 1st relaying bar 81, the described operation hawser 83 of relaying tube the 80, the 2nd relaying bar 82 push-and-pulls operates swing control valve.

On the right side of the top of described pedal support component 23 23a, be fixed with the top of the axis direction of columned support stick 84, the bottom of this support stick 84 is the shape between the limiting wall 27 that is inserted in front and back.

The bottom of this support stick 84 is provided with holding section 47.Therefore, be positioned under the state of neutral position holding section 47 location skew to the right under the axle center Y of pivot 35 at operating pedal 22.

Again, in this example, this holding section 47 constitutes by rotate a pair of (a plurality of) axle collars 85 cylindraceous (rotatable parts) up and down that are supported on freely on the support stick 84 around the axle center.

On each axle collar 85, be embedded with the lining 86 (the nothing oil axle bushes of DU lining etc.) of tubular, the axle collar 85 is by these lining 86 outer being enclosed within on the support stick 84, and thus, this axle collar 85 rotates smoothly.

About the holding section 47 of support stick 84, be provided with the jump ring that moves that is used to limit the axle collar 85 (Japanese: ジ Network サ one Network リ ッ プ) 87, between the jump ring 87 of the axle collar 85 of upside and upside, be provided with the outer band rubber washer 88 that is enclosed within on the support stick 84.

Be positioned under the state of neutral position (when swing control valve and accessory control valve are in neutral condition) at operating pedal 22, the axle collar 85 up and down (is positioned at the position in the face of the slot 49 of front and back) between the slot 49 of front and back, swing to the left and right from the neutral position by making operating pedal 22, thereby make the axle collar 85 between limiting wall 27, move and limit the swing of operating pedal 22 to the left and right, by operating pedal 22 is swung forwards, backwards from the neutral position, limit swinging of operating pedal 22 in the slot 49 thereby the axle collar 85 is inserted in.

As above-mentioned, move between relative a pair of limiting wall 27 by making holding section 47, thereby allow operating pedal 22 a side swing and the restriction the opposing party swing, by holding section 47 is inserted in the swing restricted guidance portion 49 that forms on each limiting wall 27, allow operating pedal 22 the opposing party swing and limit a side swing, in this structure, for operating pedal 22 is moved smoothly, must between the restriction face 49a of between the opposite face 27a of holding section 47 and limiting wall 27 and holding section 47 and swing restricted guidance portion 49, gap S1 be set, S2, but as this gap S1, when S2 became big, it is difficult that the restriction of operating pedal 22 can become.

In described example, form holding section 47 by the axle collar 85 that rotates, therefore, even if the axle collar 85 contacts with the opposite face 27a of limiting wall 27 or the restriction face 49a of slot 49, contact resistance also can diminish because of the axle collar 85 rotates.

Therefore, a kind of manipulation device can be provided, the parts that rotated by the axle collar 85 grades form holding section 47, can make the gap S2 between the restriction face 49a of gap S1 between holding section 47 and the limiting wall 27 and holding section 47 and swing restricted guidance portion 49 as far as possible little, can fully have the swing limitation function of operating pedal 22 and can make the action of operating pedal 22 smooth and easy.

Again, forms holding section 47 by the parts that rotate, thereby when trampling operating pedal 22, owing to holding section 47 can not engage with limiting wall 27, so the trampling of operating pedal 22 condition of poor can not occur, in addition, it is minimum that resistance sense becomes, and operability is good.

In addition, in this example, for the link gear of be connected operating pedal 22 and swing control valve, the link gear of be connected operating pedal 22 and accessory control valve, its play (operation of operating pedal 22 does not have influence on the scope of the action of control valve guiding valve) is less.Therefore, when operating (when the 2nd direction of operating B operates operating pedal 22), must strictness limit this operation, so that can not operate by 22 pairs of accessory control valves of operating pedal by 22 pairs of swing control valves of operating pedal.

Therefore, in the 3rd example, as shown in figure 19, the opposite face 27a of the limiting wall 27 of front and back and the restriction face 49a of gap S1 between the axle collar 85 and slot 49 and the gap S2 between the axle collar 85 (when the axle collar 85 inserts slots 49, the minimum clearance of the restriction face 49a of the axle collar 85 and slot 49) compare littler.

Though described holding section 47 also can be made of the single axle collar 85, but, consider when this holding section 47 of adopting the single axle collar 85 to constitute go up independent and limiting wall 27 butts of next side the time, the rotary resistance difference of part can make holding section 47 rotate more swimmingly, therefore, in described the 3rd example, holding section 47 is made of a pair of axle collar 85 up and down, because the upper and lower of holding section 47 can be rotated individually, therefore, even the independent butt of upward next side of holding section 47 also can rotate swimmingly.

In addition, holding section 47 also can be made of the axle collar more than 3 85 (rotatable parts) of above-below direction.

As shown in figure 16, be positioned at operating pedal 22 under the state of neutral position again,, because holding section 47 location skew to the right under the axle center Y of pivot 35, therefore, around pivot 35 from the neutral position when left carries out swinging operation to operating pedal 22, rise to right-hand swing in holding section 47; Around pivot 35 from the neutral position to right-hand when operating pedal 22 is carried out swinging operation, holding section 47 is to the left swing and descend.Corresponding to this, the height of limiting wall 27 is that the left side of swing restricted guidance portion 49 is lower than the right side.

And, configuration swinging mounting axle 28 above left side of swinging restricted guidance portion 49 and limiting wall 27, this swinging mounting axle 28 is configured near the upper surface in left side (the step-down side of limiting wall 27) of limiting wall 27, and the supporting mechanism of operating pedal 22 is constituted compactly.

On the other hand, as shown in figure 17, because 47 positions, holding section are displaced to the more rear side of the axle center X of swinging mounting axle 28, when around swinging mounting axle 28 from the neutral position when swinging operation is carried out to operating pedal 22 in the front side, holding section 47 side oscillation and making progress backward, when around swinging mounting axle 28 from the neutral position when rear side carries out swinging operation to operating pedal 22, holding section 47 side oscillation and descending forward.Therefore, the slot 49 bottom surface 19b of rear side are than the bottom surface 19b of the slot 49 of front side higher (groove depth of the slot 49 of front side is also darker than the groove depth of the slot 49 of rear side).

Because the below between a pair of limiting wall 27 is open shape, therefore do not worry because of between limiting wall 27, being detained the mobile variation that soil and rubbish etc. make operating pedal 22 again.

Again, in the 3rd example, in that rocking bracket 25, pedal support component 23, operating pedal 22, relaying tube 80, interlock link rod 77 etc. are assembled under the state of support unit 24, by being bolted to the bottom of turntable 8.

Again, this example also can have various design alterations, for example, also can be: the 1st direction of operating A be left and right directions (incline direction that perhaps relative left and right directions tilts), and the 2nd direction of operating B is fore-and-aft direction (a perhaps relative fore-and-aft direction Qing Xie De Pour tilted direction).

Again, in this example, though be that example represents that functional unit 22 also can adopt action bars etc. as the functional unit 22 that can operate with the operating pedal on the 1st direction of operating A and the 2nd direction of operating B both direction.

In described the 1st, 2 example, also can adopt the swing restricted guidance portion 49 that constitutes by groove and by by contact the holding section 47 that at least one rotatable parts of rotating constitute with limiting wall 27 again.

Again, direction of operating A, the B of the operating pedal 22 of the 3rd example also can be identical with described the 1st, 2 examples, become the incline direction of direction inclination relatively all around.

Also can the direction of restrictions 27 (limiting wall) and swing restricted guidance portion 49 (connecting hole, slots) suitably be changed again.
