The section 9a is connected to the operation cable 8 via an arc-shaped connecting rod 11 connected to the arm section 9a so as to rotate about an axis parallel to the support shaft 10. When the clutch lever 9 is swung in the longitudinal direction of the fuselage around the axis 10a of the lever support shaft 10 in the lateral direction of the fuselage to the clutch engaging position shown in FIG. To the rear side of the fuselage to pull the operation cable 8, and the operation cable 8 switches the operation arm of the main clutch 7 to the clutch engagement side. At this time, the connecting rod 11
, The clutch lever 9 is held at the clutch engaged position against the self-restoring force of the main clutch 7 for disengaging the clutch, and the main clutch 7 maintains the clutch engaged state. When the clutch lever 9 is swung from the clutch engaged position to the rear side of the fuselage to switch to the clutch disengaged position shown in FIG. 2B, the connecting arm 9a moves the connecting rod 11 to the front side of the fuselage. When the operation cable 8 is loosened, the operation arm of the main clutch 7 is switched to the clutch disengaged position by the self-restoring force of the main clutch 7.

That is, the main clutch 7 can be switched by swinging the clutch lever 9 around the shaft center 10a, and the main clutch 7 can be used to connect and disconnect the transmission from the engine E to the left and right wheels 1,1. The clutch is operated by operating the clutch lever 9 to the clutch engagement position to perform the traveling operation of the aircraft, and by operating the clutch lever 9 to the clutch disengagement position to perform the traveling stop operation of the aircraft.

The engine E is provided with a recoil starter device 12 for starting the engine E, as shown in FIG.
An operation in which a start cable 13 of the starter device 12 is extended rearward of the fuselage, and a start operation tool 14 located at an end of the start cable 13 is attached to the steering handle 3 near the clutch lever 9. Tool holder 1
5 is supported. Spindle 21 provided on steering handle 3
Swing links 22a, 22 rotatably mounted on
b, a swing link 2 of the swing body 22
A first interlocking mechanism configured to link the rocking body 22 to the clutch lever 9 by connecting the tension coil spring 23 attached to the control handle 3 and the swing link 22a of the rocking body 22 to the connecting rod 11; The rocking body 22 is connected to the clutch lever 9 by connecting the rocking link 22a of the rocking body 22 to the cable 24 and the interlocking arm 9b of the clutch lever 9 extending integrally and rotatably from the boss portion of the clutch lever 9. An interlocking mechanism 20 for interlocking the recoil starter device 12 with the main clutch 7 is constituted by each of the second interlocking cables 25 configured to interlock. The oscillating body 22 includes the pair of oscillating links 22a and 22b, and both oscillating links 22a and 22b.
And a pivoting link 22a, 2 which is rotatably mounted on the support shaft 21.
2b, the free ends of the connecting members 22b are connected to each other, and the connecting members 22d are configured to operate as shown in FIGS. 2 and 3, so that the main clutch 7 can be engaged. The interlocking mechanism 20 enables the engine E to be started while automatically switching this to off.

That is, the oscillating body 22 normally operates as shown in FIG.
As shown in FIG. 3A and FIG.
The swing link 22b is in a first mounting position in which the swing link 22b is in contact with the first stopper 26 for the swing operation by the pulling force of the pulling coil spring 23 acting on the mounting cylinder 22c and the connecting cylinder 22c and the connecting rod 22d. The cable 13 is wound. At this time, if the starting operation tool 14 is still attached to the operation tool holder 15, the clutch lever 9
The first and second interlocking cables 24 and 25 are in a tension state in which the rocking body 22 does not swing against the coil spring 23 even when the lever is switched between the clutch engagement position and the clutch release position. The rocking body 22 maintains the first mounting posture only by switching to the loosened state. As shown in FIG. 2A, when the swinging body 22 is in the first mounting position and the clutch lever 9 is in the clutch engaged position, the starting operation tool 14 pulls the starting cable 13 to the rear side of the fuselage. Cable 13
As shown in FIG. 2A, the swinging member 22 is pushed against the coil spring 23 by pressing against the connecting rod 22d in order to extend from the bent state in which the swinging member 22 is wound around the swinging member 22, and swings in the rotation direction A shown in FIG. Operation. As the oscillating body 22 oscillates, the connection point of the coil spring 23 in the oscillating link 22b is changed to the oscillating axis of the oscillating link 22b and the coil spring 23.
Exceeds the dead point located on an imaginary straight line connecting the support point of the steering handle 3 in the turning direction A, the coil spring 23 thereafter moves in the opposite direction to the swing link 22b with respect to the swing link 22b. Swinging operation in the turning direction A of. Then, due to the swing operation by the tensile force of the coil spring 23, the swing body 22 is switched to the second mounting posture in which the swing link 22b contacts the second stopper 27, as shown in FIG. The starting cable 13 enables the recoil starter device 12 to be operated and the second interlocking cable 25 is pulled. Therefore, the second interlocking cable 25 acts on the interlocking arm portion 9b to switch the clutch lever 9 from the clutch engaged position to the clutch disengaged position. When the clutch lever 9 is switched from the clutch disengaged position to the clutch engaged position while the rocking body 22 is in the second mounting position, the connecting rod 11 causes the rocking body 22 to move through the first interlocking cable 24 as shown in FIG. The swing operation is performed against the coil spring 23 in the rotation direction B shown in FIG. When the connecting point of the coil spring 23 in the swing link 22b exceeds the dead point in the rotation direction B as the swing body 22 swings, the coil spring 23 thereafter moves with respect to the swing link 22b. Swings in the turning direction B in the opposite direction. Then, for the swing operation by the tensile force of the coil spring 23, FIG.
As shown in FIG. 7, the swinging body 22 is switched to the first mounting position, the starting cable 13 is wound around the mounting cylinder 22c and the connecting rod 22d, and then the swinging body 22 is pulled when the starting cable 13 is pulled. Turns in the turning direction A to enable the second interlocking cable 25 to switch the clutch lever 9 from the clutch engaged position to the clutch disengaged position.

That is, in starting the engine E, the starting cable 8 is pulled by removing the starting operation tool 14 from the operation tool holder 15 and pulling the starting operation tool 14 rearward. At this time, when the main clutch 7 is disengaged, the oscillator 22 is connected to the starting cable 13.
Even if the first mounting posture is switched to the second mounting posture due to the tension, the second interlocking cable 25 does not perform the switching operation of the clutch lever 9. Therefore, the interlocking mechanism 2
0 keeps the main clutch 7 off by leaving it inactive and leaving the clutch lever 9 in the clutch off position. Then, the starting cable 13 transmits a starting operation force to the recoil starter device 12, so that the recoil starter device 12 operates to start the engine E. On the other hand, when the main clutch 7 is engaged, the rocking body 22 is switched from the first mounting position to the second mounting position by the tension of the starting cable 13, and the second interlocking cable 25 engages the clutch lever 9. Switch from the engaged position to the clutch disengaged position. That is, the interlocking mechanism 2
0 is the second interlocking cable 25 which takes in the cable tension from the starting cable 13 by the rocking body 22 as the operating force.
As a result, the cable tension is transmitted as an operating force to the second interlocking arm portion 9b to switch the clutch lever 9 from the clutch engaged position to the clutch disengaged position, and
Automatically switches from on to off. Then, the start cable 13 transmits the starting operation force to the recoil starter device 12 while oscillating the oscillating body 22, so that the recoil starter device 12 operates to start the engine E.

After the engine E starts, the clutch lever 9 is switched from the clutch disengaged position to the clutch engaged position, whereby the main clutch 9 is switched from disengaged to engaged, and the left and right traveling wheels 1, 1 and the rotary The engine output is transmitted to the connection work device such as the tilling device 5, so that the machine body traveling and the work by the connection work device can be performed. Even if the engine start operation is performed with the main clutch 7 engaged, when the clutch lever 9 is subsequently switched to the clutch engagement position,
The rocking body 22 of the interlocking mechanism 20 automatically switches from the second mounting posture to the first mounting posture for interlocking with the clutch lever 9 by the first interlocking cable 24,
The interlocking mechanism 20 then enables automatic switching of the main clutch 7.

An accelerator operating device having an accelerator lever 31 interlocked with an accelerator device (not shown) of the engine E via an operating cable 30 is provided near the grip portion of the steering handle 3 and is shown in FIG. It is configured as shown.

That is, the accelerator lever 31 is attached to the base member 32 fixed to the steering handle 3 by the cover 3.
3 is attached to the mounting screw 3 so as to be rotated by a lever support shaft 34 which is also used. The disc spring 35 disposed between the base of the accelerator lever 31 and the cover 33 is pressed against the base of the accelerator lever 31 by the tightening force of the lever support shaft 34 and is elastically deformed. Is pressed against the lever receiving portion 32a of the base member 32 to generate a frictional force between the accelerator lever 31 and the base member 32. A positioning ball 36 is attached to the base of the accelerator lever 31 so as to move with respect to the base member 32 together with the accelerator lever 31, and the accelerator lever 31 is swung to position the positioning ball 36 by a through hole of the base member 32. The accelerator lever 31 is configured to be in the idle position AI when it enters the recess 32b.

That is, when the accelerator lever 31 is swung about the axis of the lever support shaft 34, the accelerator lever 3
1 performs the pulling operation or the loosening operation of the inner cable 30I of the operating cable 30 along the cylindrical outer peripheral surface 32c of the lever receiving portion 32a of the base member 32 as a cable guide, thereby operating the accelerator device in the engine stopped state. Idling state, and
The operation can be switched to a running speed range higher than idling. When the vehicle is operated in the traveling speed range or when performing a speed change operation in the traveling speed range, the friction between the accelerator lever 31 and the base member 32 causes the accelerator lever 31 to self-restoring force of the accelerator device to the engine stop state. To maintain the accelerator device in a predetermined operating state. When the accelerator device is operated in the idling state, the positioning ball 36
Penetrates into the positioning recess 32b and locks the base member 31, thereby holding the accelerator lever 31 at the idling position AI against the self-restoring force of the accelerator device, thereby maintaining the accelerator device in the idling state. . In this case, when the accelerator lever 31 is at the idling position AI, this is determined by the positioning ball 36.
Can enter into the positioning recess 32b. In addition, the accelerator lever 31 is moved to the idling position A
By simply swinging in the predetermined direction from I, the positioning ball 36 is detached from the positioning recess 32b, and the accelerator lever 31 moves to the traveling side or the engine stop side. Therefore, when the accelerator lever is moved to the idling position, the stopper acts to recognize the arrival at the idling position, and the accelerator lever is pivoted while releasing the stopper by a manual operation so that the accelerator lever is moved from the idling position. A special means for releasing the means for recognizing that the accelerator lever has reached the idling position so that the accelerator lever can be moved, as compared to a case where the accelerator lever is moved to a predetermined traveling side or an engine stop side. The operation of the accelerator lever is easily and quickly switched to the traveling side or the engine stop side without requiring a complicated switching operation, so that the traveling of the body and the driving of the connecting work device can be quickly enabled or stopped.

A pair of steering clutches (not shown) are arranged in the transmission case 2 so that the pair of right and left traveling wheels 1 and 1 are separately driven to stop and the operation of changing the traveling direction of the aircraft is performed. As shown in FIGS. 5 and 6, a clutch operation arm 41 a or 41 b attached to the rotation operation shaft 40 a or 40 b of each of the pair of steering clutches so as to be integrally rotatable is disposed outside the transmission case 2. The pair of clutch operating arms 41a and 41b are connected to the operating arms 41a or 41b by the connecting members 42a or 4b.
Operation cable 43a or 43b connected by 2b
By interlocking the steering levers 44a and 44b separately to the pair of steering levers 44a and 44b separately located on the left and right sides of the steering handle 3 through the steering wheel 3 and operating the steering lever 44a or 44b to the cut side, the lever operation force is used. The steering clutch is disengaged and the steering clutch is disengaged, and the steering lever 44 is disengaged.
The steering lever 44a or 44b and the restoring force of the steering clutch to the entrance side are caused by the self-restoring force of the steering lever 44a or 44b and the restoring force of the steering clutch to the entrance side. It is configured to return to the on position and operate the steering clutch on.

As shown in FIG. 5, the outer cable of the operation cable 30 connecting the accelerator device of the engine E and the accelerator lever 31 is connected to an outer cable portion 30A on the accelerator device side and an outer cable portion 30L on the accelerator lever side. And by connecting the outer cable portions 30A and 30L so as to be relatively slidable in the longitudinal direction of the operation cable 30, the accelerator adjusting mechanism 50 is configured. By operating the accelerator adjusting mechanism 50, The shift of the accelerator device of the engine E can be adjusted. That is, when the accelerator adjustment mechanism 50 is operated to the side where the length of the outer cable portion 30A on the accelerator device side protruding from the outer cable portion 30L on the accelerator lever side is increased, the outer cable length becomes the normal length, The travel speed of the accelerator device is set by the accelerator lever 31. Then, the outer cable portion 30A on the accelerator device side is connected to the outer cable portion 3 on the accelerator lever side.
When the accelerator adjustment mechanism 50 is operated to the side where the length protruding from 0L becomes shorter, the outer cable length becomes shorter than the normal length, and the operation cable 30 acts to decelerate the accelerator device. The steering low speed is reduced by the speed determined by the shortened stroke of the outer cable from the set traveling speed.

Outer cable part 3 on the accelerator device side
0A, an inner cable 53a connected to a cable connector 52 included in the transmission case 2, and an outer cable 53b having one end held by an outer holder 54 included in an outer cable portion 30L on the accelerator lever side. A coil spring 55 provided between the cable connecting member 51 and the outer holder 54 so as to separate and urge the cable connecting member 51 and the outer holder 54; and the other end of the outer cable 53b of the interlocking cable 53. And an outer holder 56 connected to the transmission case 2 so as to be swingably supported around a shaft core 56a.
Thus, an interlocking mechanism 57 for interlocking the accelerator adjustment mechanism 50 with the pair of steering clutches is configured, and the interlocking mechanism 57 causes the accelerator adjustment mechanism 50 to interlock with the switching operation of the pair of steering clutches. It is configured to operate automatically. That is, when any one of the pair of steering clutches is operated to the disengagement side, the operation cable 43a or 43b is pulled and the connecting tool 4 is operated.
In order to raise the clutch operation arm 41a or 41b to the clutch disengagement position via 2a or 42b, the coupling tool 42a or 42b pushes up the outer holder 56. Then, the outer holder 5
6 moves the outer cable 53b of the interlocking cable 53 toward the accelerator adjusting mechanism 50 against the coil spring 55, so that the protruding length of the outer cable portion 30A from the outer cable portion 30L is reduced. As a result, the interlocking mechanism 57 automatically switches the accelerator adjusting mechanism 50 to the steering low-speed side in conjunction with the disengagement operation of one of the steering clutches. When the steering clutch which has been operated to the disengagement side is returned to the ingress side, the operation cable 43a or 43b is loosened and the coupling tool 42a or 42b is also moved to lower the clutch operation arm 41a or 41b to the clutch engagement position. It descends to release the push-up operation on the outer holder 56.
Then, the outer holder 53 is lowered until the outer holder 53 is received by the coupling tools 43a and 43b for the pushing operation by the coil spring 55, and the outer cable 53b of the interlocking cable 53 is moved from the accelerator adjusting mechanism 50 to the clutch operating levers 40a and 40b. To the outer cable portion 30A of the outer cable portion 30A.
The protruding length from L returns to the original long length. Thus, the interlocking mechanism 50 automatically switches the accelerator adjusting mechanism 50 to the traveling set speed degree side in conjunction with the engagement operation of the steering clutch.

That is, the left or right steering lever 44a
Alternatively, the airframe is steered rightward or leftward by operating the steering wheel 44b to stop driving either the left or right traveling wheel 1 by operating one of the steering clutches. At this time, the interlocking mechanism 57 and the accelerator adjusting mechanism 5
Because of 0, the accelerator device of the engine E automatically switches from the set speed for traveling set by the accelerator lever 31 to the low speed for steering, and the rotational speed of the engine E becomes lower than when traveling straight. As a result, the traveling wheels 1 located outside the turning of the fuselage are automatically decelerated and driven as compared with the straight running, so that the operation can be performed at a low speed without operating a special deceleration operation only by operating the steering lever 44a or 44b. The aircraft steers and turns.

FIG. 7 shows another embodiment of the interlocking mechanism 57 for interlocking the accelerator adjusting mechanism with the steering clutch.
That is, the outer cable 53 of the interlocking cable 53
Outer holder 56 for holding the clutch side end of b
Are connected so as to be supported by the transmission case 2 via a pair of support links 58, 58 which are respectively swingably connected to both ends thereof. That is, when the steering clutch is disengaged and the connecting tool 42a or 42b pushes up on the outer holder 56, the operating force causes the pair of support links 58, 58 to swing upright with respect to the transmission case 2, and When the steering clutch is engaged to release the pushing of the connecting tool 42a or 42b against the outer holder 56, the pair of support links 58, 58 is released.
Swings to the falling side with respect to the mission case 2. For this purpose, the outer holder 56 moves to the side separated from the support point of the inner cable 53a by the transmission case 2 in conjunction with the disengagement operation of the steering clutch, and moves the outer cable 53b to the accelerator adjusting side, The outer cable 53b can return to the side approaching the inner cable support point in conjunction with the operation of engaging the steering clutch. Thus, the accelerator adjusting mechanism is automatically operated in conjunction with the operation of the steering clutch.

FIG. 8 shows a further embodiment of the interlocking mechanism 57 for interlocking the accelerator adjustment mechanism with the steering clutch. That is, the pair of clutch operation arms 41a,
41b from each cable connecting arm 59a or 5
9b is extended so as to swing integrally, the inner cable 53a of the interlocking cable 53 is connected to one of the pair of cable connecting arms 59a, 59b, and the outer cable 53b of the interlocking cable 53 is connected to the other cable connecting arm 59b. Is held at the end. That is, when one of the pair of steering clutches is disengaged or returned to the on state, the cable connection arm 59a or 59b is engaged together with the clutch operation arm 41a or 41b.
b swings, and the cable connection point interval between the cable connection arms 59a and 59b increases or returns to the original narrow interval, so that the inner cable 53a is slid with respect to the outer cable 53b. Thus, the accelerator adjusting mechanism is automatically operated in conjunction with the operation of the steering clutch.

FIG. 9 shows an accelerator device and an accelerator lever 3.
1 shows another embodiment of an accelerator adjusting mechanism 50 that acts on an operation cable 30 connecting the first and second gears 1 and 2 to perform a shift operation of an accelerator device. That is, a pair of outer cable portions 30A of the operation cable 30 that are connected so that the outer cable portion 30A on the accelerator device side and the outer cable portion 30L on the accelerator lever side are relatively swung about the axis thereof by the connecting pin 60. The holders 61a and 61b are separately held. When one of the outer holders 61a is swung to the side separated from the other outer holder 61b, the outer cable length becomes a normal length, and the accelerator device is set by the accelerator lever 31. Adjust to the set traveling speed. When one of the outer holders 61a is swung toward the side closer to the other outer holder 61b, the outer cable length becomes shorter than the normal length, and the operation cable 30 acts to decelerate the accelerator device. For this purpose, the accelerator device is adjusted to a low steering speed that is lower than the set traveling speed by a speed determined by the shortened stroke of the outer cable.

Alternative Embodiment When the main clutch is also used as the traveling clutch as in the above-described embodiment, the connection between the engine and the connection working device is automatically cut off, and the operation of the recoil starter device can be advantageously reduced. However, the present invention can also be applied to a case where a clutch dedicated to the traveling device that connects and disconnects transmission from the engine only to the traveling device such as a traveling wheel is employed. Therefore, the main clutch 7 is referred to as a traveling clutch 7.
