For example, the center of rotation of the axis of the lifting arm body 41 is about 1.5 m above the ground in the illustrated example, while the center of rotation of the axis of the lifting arm body 41 and the turning axis 7 are.
The distance between the axis of rotation of the bucket axis rotating around 5 is about 2.5 m. Therefore, the vehicle has a lift of about 3 m, and the swing shaft 75 connecting the bucket 49 is located in front of the front end portion 12 of the vehicle over the entire lift.

Next, propulsion and loader control will be described. The transmission 21 comprises a pair of conventional, conventional wash plates, hydrostatic pumps 90, 91.
The output of the hydrostatic pump is delivered to a conventional hydraulic motor 92 in a conventional manner. In this embodiment, the rearmost pump 90 provides power to the motor 92 on the left side of the vehicle, while the pump 91 provides power to the opposite pump on the right side of the vehicle, not shown. Has become. The pumps 90 and 91 are respectively provided with input members 93 and 9
4 each of which is rotatable about parallel axes which extend perpendicular to the longitudinal axis of the vehicle and are spaced apart substantially in the horizontal plane. In this example,
The input members 93 and 94 are coupled to each other by a fluid pressure servo mechanism incorporated in the fluid pressure pump by a conventional general method.
ate) angle. However, if desired, the input member may be directly mechanically driven by an angle of the water control plate in a conventional manner.
The vehicle is equipped with a suitable chain connecting manually operable propulsion control means 24 to said input members 93, 94 in order to achieve the desired mechanism for controlling the angle of the water control plate.
One such mechanism is shown in FIG. 7, in which, when the propulsion control member takes various different angular positions, the angles taken by the water control plate and the corresponding input members. The relationship between the angular positions of 93 and 94 is shown. The graph of FIG. 7 shows that the propulsion control member 95 moves to the maximum at any angular position and, conversely, the movement range of the water control plate of each pump is reduced, but the same pattern of the water control plate control is performed. Assumes less movement in any particular direction. The control member 95
7 in the frontmost position, that is, in a state parallel to the front-rear direction of the vehicle, is moved to a position of 0 ° in FIG. 7, both input members 93, 94 in the state shown in FIG. 3 or FIG. Rotate clockwise as you can see,
Causes forward movement of the left and right propelling means.

When the lever is moved to the right by 45 ° to the position of 45 ° in FIG. 7, the chain moves to a position where the water control plate does not supply liquid to the motor, that is,
The input member 94 is placed at the neutral position, while the input member 93 of the water control plate that drives the left motor 92 is used.
Remains in the foremost position, which results in the vehicle turning to the right. As shown at 90 ° in FIG.
By moving the member 95 in the direction of 90 ° to the right, the input member 94 is operated so as to output a signal for moving the water control plate so as to drive the water control plate in the opposite direction, while the input member 93 is operated at the maximum. Being held in the front position, the vehicle will begin to rotate on its central axis. By moving the control member 95 to the position of 135 ° to the right, the input member 9
No. 4 remains held completely in the opposite direction, while the input member 93 will be moved to the neutral position where the water control plate produces no output. When the lever 95 is moved in the reverse direction (the direction indicated by 180 ° in FIG. 7) parallel to the front-rear direction of the vehicle, the input member 94 is held in the completely reverse position, while the input member 93 also Moved to the completely opposite position. 225 ° in FIG. 7,
A similar chaining action occurs when lever 95 is moved to the corresponding left position, as shown at 270 ° and 315 °. A mechanical chain for the purpose of realizing the above mechanism is shown in FIG. Input member 93, 9
4 are provided with input levers 96 and 97, respectively, and these input levers 96 and 97 are provided at the lower end of the operating lever 100 at A3 and A4 respectively at links 98 and 99 connected by ball joints at A and A4.
They are connected by ball joints at positions 1 and A2. All of the nodes A1, A2, A3, A4 are located in a plane above the plane including the rotation axes of the input members 93, 94 and spaced apart from the plane and parallel to the plane. Lying down.

The operating lever 100 is a parallelogram chain 10
It is rotatably attached to a part 101 of the vehicle body 11 so that it can be freely operated by the action of 2. The chain 102 comprises a first hook joint 103.
One yoke (yo) of this first hook joint 103.
ke) 104 is fixed to the upper end of the operating lever 100, and is one yoke 105 of the joint 106 of the second hook.
Has also been fixed. This second hook fitting 106
The other yoke 107 is fixed to a part 101 of the vehicle body. The second yoke 108 of the first hook number joint 103 is connected to the first yoke 110 of the third hook joint 111 by a link 109, and the second yoke 108 of the third hook joint 111 is connected. The yoke 112 is connected to the first yoke 113 of the joint 114 of the fourth hook. The second yoke 115 of the joint 114 of the fourth hook is fixed to the part 101 of the vehicle body. In addition, the second yoke of the third hook joint 111 has a propulsion control member 95 thereon. Thus, the movement of the control member 95 in either radial direction, which is allowed by the fourth hook joint 114 as described above, is transmitted to the operating lever 100 by the link 109 and the hook joint assembly 103, 106. To be done. The line connecting the connection point B of the hook joints 106, 114 with the part 101 of the vehicle body is parallel to the line connecting the points A1, A2, but is a plane located at a distance above the plane containing A1-A4. Exists within. Thus, for example, movement of the propulsion control member 95 in the forward direction F, which is parallel to the longitudinal axis of the vehicle, causes the input members 93, 94 to rotate in a clockwise direction in order to provide the pump with output for advancing the vehicle. The movement in the reverse direction Rv that causes rotation occurs at points A3 and A4. Similarly, the control member 95 in the reverse direction Rv
Movement causes forward movement F at points A3 and A4,
Counterclockwise rotation of each of the input members 93, 94 is caused to reverse the vehicle. Lever 95 in direction R
Movement of the vehicle, ie, to the right of the longitudinal axis, causes the vehicle to move to the right at points A3 and A4, which causes the input member 93 to rotate clockwise. , The left ground propulsion unit is rotated forward,
On the other hand, the input member 94 is rotated counterclockwise to cause the right side ground propulsion unit to rotate in the opposite direction,
As a result, spin occurs on the central axis of the vehicle. When the member 95 is moved to the left in the direction of the arrow L,
The points A3 and A4 are moved to the right in the direction of the arrow R, which causes the member 93 to rotate counterclockwise,
A reverse drive force is applied to the left propulsion unit, while clockwise rotation is produced in the input member 94 such that the right propulsion unit rotates forward, resulting in a vehicle on its central axis. , This time in the opposite direction, ie, to the left, causing a rotation. By moving the lever 95 at an angle of 45 ° with respect to any one of the aforementioned directions,
A combination operation is generated. For example, control lever 95
Is moved 45 ° to the right, that is, in FIG.
When it is moved to the center position between the front and the right side, as shown in FIG. 8, A3 and A at the center position of 45 ° between Rv and L.
Corresponding movements of point 4 occur, holding the input member 94 in its neutral position, so that no driving force is exerted on the right ground propulsion means, while the input member 93 is largely clocked. Moved around, it provides sufficient forward force to the left-hand propulsion means, causing the vehicle to steer to the right. For other movements of the lever 95 of 45 °, a corresponding combination movement takes place and also a combination movement of the control members 93, 94 in the other positions is obtained according to FIG. The dimensions of the chain in one particular example are as follows: However, as will be appreciated by those skilled in the art, other dimensions than those listed here are possible.

The ratio of the control force between the lateral movement and the longitudinal movement of the control member 95 can be adjusted by changing the length of the links 98, 99, in the case of the illustrated example 150 mm. When the length is long and the distance between the points A1 and A2 at the neutral position of the pump is 240 mm, each part between the links 98 and 99 and the line connecting the points A1 and A2 is 45 °. The longer the link, the greater the force required for lateral movement of the member 95, the smaller the lateral travel distance, and the biasing of the control member 95 for linear movement. FIG. 9 shows a fluid pressure chain as an alternative technique. The fluid pressure pump and the motor used in this fluid pressure chain are the same as those used in the embodiment shown in FIG. Similarly, each of 93 and 94 includes input levers 96 and 97. However, the levers 96 and 97 respectively have double-acting hydraulic rams 122 and 123.
Is connected to the piston rods 120 and 121. Each of the hydraulic rams 122, 123 has a vertical axis 125,
It is attached to a part 128 of the vehicle body so as to be rotatable around 126. The vertical axes 125 and 126 are parallel to the central axes of rotation of the input members 93 and 94, respectively. Each of the piston rods 120 and 121 is provided with a head portion 120a, 120b; 121a, 121b, and each of the rams 122, 123 is provided with a corresponding cylinder 122a, 122b; 123a, 123b, and each cylinder is , Entrance 127a, 12
7b; 128a and 128b. The respective input levers 96 and 97 are interlocked with the central levers 130 and 131, and the central levers 130 and 131 are connected to the vehicle body 11 respectively.
It is rotatably attached to the fixed part 134 at 132 and 133 points. The central levers 130 and 131 respectively have the coil springs 135a and 135b and the joint portions 138a and 138b of the input levers 96 and 97;
Balls 136a, 136b engaging with 139b; 137
It is urged to rotate by a and 137b. here,
If necessary, instead of two springs, levers 130,
It is also possible to use one spring that connects the 131 to each other. The shafts 132 and 133 interlock with the ball 136 of the central levers 130 and 131 when the input members 93 and 94 are in the neutral position and the water control plate does not output.
a, 136b; 137a, 137b by the joint 13
8a, 138b; 139a, 139b are positioned so that they engage one another, so that the input member 9
No matter which direction the 3,94 are moving from the neutral position, a biasing force is applied to return from the neutral position to the neutral position, and therefore, the neutral position is always held when there is no input. . It should be noted that the center return means described above, although not explicitly shown in FIG. 8, is equally applicable to the mechanical chain described in connection with FIG. Next, referring to FIGS. 10 and 11, the propulsion control member 95 is appropriately movable to the base portion 141 fixed in a relative relation to the vehicle body 11 so as to be freely movable around the point P.

Further, they are arranged at positions equidistant from each other in a plane parallel to the longitudinal axis of the vehicle. The plungers 144-147 are biased by a spring force so as to engage with the surface member 143, and the spring force causes an equal bias to return the member 95 to the vertically standing position as shown in FIG. This allows the member 95 to autonomously return to the neutral position when the member 95 is tilted in any direction. Two additional spring-biased plunger members, shown at 148, are attached to the universal joint 140 relative to the universal joint 140 on a line perpendicular to the longitudinal direction of the vehicle to provide the control member 95 with a biasing force when moving in the forward and reverse directions. They are located at opposite positions. The biasing force exerted by this plunger 148 is much stronger than the biasing force exerted by the plunger 144, and therefore the force exerted to return the member 95 to the vertical state when tilted rightward or leftward. Which is greater than the force that is required to return to a vertical position when tilted forward or backward. This is the member 95
A vehicle that has a biasing force to move the vehicle back and forth and that requires a stronger operating force to steer the vehicle to the right or left is configured, thereby facilitating forward and backward operation of the vehicle. And make the vehicle safer. The valve operated by the plunger 144 is
Adjusted to supply pressurized fluid, when the plunger 144 is pushed against the port 127b of the ram 122, the input member 93 begins to rotate clockwise, driving the left propulsion unit in the forward direction. Similarly, the plunger 147 causes the associated valve to supply fluid to the port 128b of the ram 123, causing the input member 94 to move the right propulsion unit in the forward direction. Plunger 145
Pressing causes the interlocking valve to direct fluid to the ram 123
Port 128a, which causes member 94 to begin rotating in a counterclockwise direction while valve member 14
By pressing 6, an interlocking valve supplies pressure fluid to port 127a of ram 122, which causes member 93 to begin rotating in a counterclockwise direction, driving the left propulsion unit in the opposite direction.

Member 95 has right plungers 144 and 145.
Pushing them towards and causes the forward movement of the left propulsion unit and the reverse movement of the right propulsion unit, so that the vehicle spins right on its axis. . Similarly, the leftward movement of member 95 pushing plungers 146 and 147 causes the left propulsion unit to rotate in the opposite direction and the right propulsion unit to move forward, resulting in a vehicle Is
Spin to the left on that axis. If the lever 95 is moved, for example, by 45 ° between the front and the right, only the valve 144 is pushed to drive the left propulsion unit forward, while the right propulsion unit is: Neither of its drive plungers 145 or 146 is pushed, so it remains in the neutral position. Similarly,
By the operation of pushing only one plunger that occurs at any of the 45 ° positions, according to the mechanism of FIG.
Only one propulsion unit has associated movements. Moving the control member 95 to an intermediate position between the 45 ° positions described above causes a combination movement depending on the degree to which the pressed valve member is pushed. In the hydraulic chain system described above, with respect to the rotation angle about the horizontal axis passing through the point P, the maximum possible movement width of the propulsion control member 95 varies depending on the various directions of movement thereof. For example, the control member 95 is moved forward and the valve operating member 1
When 44 and 147 are moved downward, the control member 95 is associated with the given travel of its valve operating member.
The width of the forward movement of A is much larger than if it were moved to the right, for example at an angle of 45 °, and only the valve member 144 was moved downward. This is because the radial distances of the flow lines of the valve operating members 144 and 147 are closer to the center of rotation of the shaft of the member 95 than the valve operating member 144, so that the control member 95 moves forward, backward, This is because it is moved with a larger width in each of the left and right directions compared to the case of the intermediate position of 45 ° between them, and the upper line in FIG. 7 shows this. Similar differences in the width of movement of the control members occur in both the mechanical linkage described above and the flexible linkage described below. In FIG.
A pair of flexible cables 150 that can be pushed and pulled,
Figure 15 shows another mechanical linkage using 151. The inner member 150a of the cable 150 is connected to the propulsion control member 95 and is moved from the outer case 150b to the inner member 150a to move the lever 95 from the neutral position to the front F.
In order to pull out and move the lever 95 in the reverse direction Rv from the neutral position, the inner member 150a is pushed against the outer case 150b. Similarly, the inner member 151a of the other cable 151 is also connected to the member 95, and in order to move the lever 95 from the neutral position to the left L, the inner member 151a is pulled out from the outer member 151b, while the member 95 is pulled to the right. To move in the direction R, the inner member 151a is pushed into the outer member 151b. Outer members 150b and 15 of the cables 150 and 151, respectively
1b is fixed to the fixing portion 152 of the vehicle body 11 at the ends adjacent to those members 95. At the other end,
The outer member 150b is fixed to the fixed portion 153 of the transmission 21, while the inner member 150b is fixed at this end.
a is rotatably connected to the parallelogram chain 154 at point A. The other end of the outer portion 151b of the cable 151 is fixed to the parallelogram chain 154 at the point B, while the other end of the inner member 151a is fixed to the chain at the point A. The parallelogram chain 154 is composed of four links 155-158 of equal length. Links 155 and 156 join together at their one end and are connected to inner members 150a, 151a at point A. At the other end, the link 155 is connected to the input lever 96 at the C point, and is also connected to the link 158 at the C point, and the other end of the link 158 is connected to the outer member 151 at the B point.
b, the link 157 is also connected at the point B, and the other end of the link 157 is connected to the input lever 97 at the point D.
Link 156 is connected here. In actual use, the movement of the lever 95 toward the front F causes the outer member 15 to move.
The inner member 150a is pulled through 0b, causing the point A of the chain to move in the upper right direction in FIG.
It causes both input levers 96, 97 to rotate clockwise, causing both pumps to drive the forward drive of their associated propulsion means. The movement of the lever 95 from the neutral position to the rear Rv causes a downward movement of the point A in FIG. 12, and as a result, the input member 9
Produces 3,94 counterclockwise movement. Lever 95
To the right R causes the inner member 151a to move point A to the left, causing the inner levers 96, 97 to rotate in opposite directions, causing points C and D to approach, resulting in , The input member 93 rotates clockwise to cause the left propelling means to drive forward, while the input member 9
4 rotates counterclockwise causing the right hand propulsion unit to move in the opposite direction. When member 95 is moved to the left L from the neutral position, member 151a
Is moved to move the point A to the right, and the input lever 9
6 and 97 rotate in opposite directions away from each other, and the input member 93 is rotated counterclockwise so as to apply a reverse driving force to the left propulsion unit, while the input member 94 is rotated. , The right propulsion unit can be rotated clockwise to give a forward drive force. When the lever 95 is moved to a position of 45 ° with respect to any of the above-mentioned right-angled directions, for example, when it is moved 45 ° to the right between the front and the right, the chain links the pump unit to the right propulsion unit. The operating lever 97 of the
2 moves to stay in the neutral position, while the operating lever 96 for the left pump is moved to the forward position, also achieving the mechanism shown in FIG. 7 for moving the lever 95 in the other direction. Similar combinatorial motions for are accomplished in a manner similar to the motion described above in connection with other mechanical and hydraulic chains.

Next, the mounting of the motor and the stub shaft will be described. Each of the side members 18 and 19 is formed of a ring-shaped case, and as shown in detail in FIG.
Each of 8 and 19 includes a lateral inner wall 160 and a lateral outer wall 161. The inner wall 160 and the outer wall 161 are connected by a ceiling wall 162, a bottom wall 163, and a side wall 164 to form an oil-tight compartment. Outer wall 16

Are formed so as to be arranged at positions eccentric with respect to the comparison shaft 176 which is forcibly rotated between the guide surfaces 166 and 167 described above. A gripping member, such as an annulus 177, allows the transfer member 168 to grip the outer wall 161 at any angular position about the comparison axis 176. By arranging the shaft 172 in the eccentric position as described above with respect to the shaft 176, the shaft 172
The position of the vehicle can be adjusted in both the longitudinal and vertical directions of the vehicle, which allows the vehicle wheel base to be adjusted in cooperation with a drive chain of appropriate length and at the same time The height of the vehicle can be adjusted in combination with a device provided to apply tension to the chain of a fixed length. The stub shaft 171 appears to be solely supported by the side wall 161 without any support provided by the inner wall 160, but this is necessary if the stub shaft is also supported by other members. This allows any machining on the wall 160 that would otherwise be avoided. In addition, a gap is provided between the sprocket member 174 and the wall 160 so that the chain can be operated through the gap space so that the chain can be engaged with the teeth of the sprocket 174. 14
Referring to FIG. 3, the mounting mode of the motor 92 on the box-shaped compartment 18 is shown. The motor 92 is a high-torque motor that is normally commercially available, and has a conventional general output shaft 180.

It can be fastened to a mounting plate 182 that is welded to the inner wall 160 of the eight. The mounting plate 182 includes a seaming member 183 and is received in a hole 184 formed in the wall 160 to help position the ring 182. A pair of driving wheels in the form of sprockets 186 and 187 are formed on the sleeve 185. The output shaft 180 is formed on the inner surface of the hollow portion of the sleeve 185.
It is received through 88. A seal 186a is provided in the hollow portion and a shaft seal 186b is provided to allow the lubricating oil supplied from the motor 92 to the spline joint 188 to bore 186c to lubricate the bearing 190 before returning to the motor 92. To flow through. The inclined roller bearing 190 is
It is provided between the outer surface of the sleeve 185 and the seat 191 provided on the main body 192 of the motor 92. The three-legged spider-shaped bracket member 193 has bolts 194.
It is fastened to the pump body 192 by. Although only one leg 195 and one bolt 194 can be seen in the figure, the other two legs and bolts are the output shaft 18
They are arranged around the rotation center axis of 0 at equal angles. Another tilted roller bearing 196 is a bracket 1
It is provided between 93 and the outer surface of the sleeve 185. A protrusion 198 is formed on the brake drum 197, and the protrusion 198 is received in the outer shell portion 199 of the hollow portion of the sleeve 185 and is rotated together by the bolt 201 at the position 200. Is splined to. The sleeve comprises a laterally extending passage 202 for receiving a fixed key to the bolt 201. Although not shown, a chain such as a roller chain is wrapped around each sprocket 186, 187, each driven sprocket 174, and other wheel sprockets not shown. In order to assemble the sprocket and the chain drive mechanism, first, the chain is fed into the box-shaped compartment 18 through the hole 203 formed in the outer wall 161, and the inner wall 160 of the box-shaped compartment 18 and the sprocket 174 are connected. Insert it between each driven sprocket. At this stage, the motor 92 is tightened in place, but the sleeve 185 and the bracket 19

The sleeve 185 is then attached to the output shaft 1
80, then the chain is sleeve 185
Corresponding sprocket 186, 187 from the outer end of the
Is installed at a predetermined position. By mounting the stub shaft in an eccentric state as described above, the stub shaft 172 can be moved toward the motor 92, and the chain can be sufficiently loosened during the above-mentioned handling. The bracket member 195 is then tightened in place, allowing the chain to pass through the space between the legs. Thereafter, the brake drum 197 is tightened in place, and finally the expansion covering member 204 is moved to the outer wall 161.

Are supported solely by the motor via brackets 195, not by any other member independent of the motor, and in particular not by the outer member 161. Therefore, the member 161 does not need to be subjected to any machining process other than the simple forming process of the opening 203 which can be formed by, for example, the frame cutting method. If desired, the motor may be mounted on the outer wall instead of the inner wall. Instead of driving the stub shafts by the output shafts of the motors passing through the box-shaped compartments, it is also possible, if necessary, to drive them by other means, for example by directly driving each stub shaft individually. May be provided. In this case, if necessary, the above-mentioned mounting method in the eccentric state with respect to the motor can be adopted so as to rotate eccentrically with the stub shaft.

Next, the driver restraint mechanism will be described. Referring to FIGS. 15 to 17, the laterally moving vehicle is provided with a restraining member 210, which is mounted on a vehicle body by a lever 211 so as to be movable between a driving position and a stopping position. There is. The driving position is the state shown in FIG. 15, in which the member extends laterally in the cab 22 and becomes restrained with respect to the seat 23, for example, the vehicle suddenly stops or leans forward. Occasionally, restrain the driver sitting in the seat so that he / she cannot fall forward. In the stopped state shown in FIG. 16, the lever 2
11 is moved from the substantially upward position that the restraint member 210 occupies when it is in the driving position to a position that extends substantially forward, so that the restraint member 210 and the lever 211 pass through the doorway 33 to the seat 23 to the seat 23. Located in a position where you can get in and out of it. Lever 211
Is rotatably supported on the vehicle body 11 by a suitable rotatably supporting means so that the vehicle can be rotated around a laterally extending shaft 212. A rigid support bar 213 is rotatably connected to the lever 211 at one end thereof. The support rod 213 is equipped with a ratchet mechanism,
As described in detail in FIG. 17, the lever 211 is adapted to engage the ratchet member to lock it in its operating position. In the embodiment shown in FIGS. 15 and 16, the restraint member 210 is of a cantilever type extending from the lever 211. The lever 211 also includes an armrest element 214 that rotates with the lever 211 and the restraining member 210. On the opposite side of the driver's cab, described as one side 31 in the above description, a fixed armrest element 215 fixed to the seat 23 is provided, the restraining member 210 being designed to sufficiently restrain the driver. It comprises a rearward extension 216 cooperating with a fixed armrest element 215. In the embodiment shown in FIGS. 15 and 16, the propulsion control member 95 described above is constituted by a mechanically rigid chain and is attached to a fixed portion of the vehicle body 11, and thus does not move together with the lever 211 as shown in FIG. However, since it is arranged on one side of the vehicle body, it does not prevent the driver from entering and exiting through the doorway on the opposite side of the vehicle body. Further, on one side of the driver's cab, an engine speed control operation lever 217 is provided on a fixed portion of the vehicle body. The lever 211 is provided with a manually operable loader control device 25.
5 operates the valve means as described above. The valve means is connected to the lifting operation ram and the device operation ram by flexible fluid pressure piping. The tubing passes through the lever 211 downwards and out of it near its lower end to the corresponding ram. The flexible pipe allows the lever 211 to rotate as described above. Next, referring to FIG. 17 showing a modified example of the restraint member shown in FIGS. 15 and 16, in this modified example,
Not only is the restraint member 210 supported by a lever corresponding to the lever 211 described above, but also at its opposite end about the common axis 212 about the lever 211.
Is also rotatably mounted in the same manner and is also supported by a second similar lever 211a with a further armrest element 214a. As shown in FIG. 17, the rigid support bar 213 has a ratchet tooth 21.
8 is provided, and this ratchet tooth has a supporting rod 2
13 meshes with a ratchet member 219 having a guide 220 that moves together to prevent it from rotating excessively. In addition, the brace bar 213 has a laterally extending projection 221 at the lower end thereof, and the driver can move the restraint member from its operating position to the stop position by moving the projection with a foot. Thus, the support bar 213 can be removed upward from the engagement with the ratchet member 219. Alternatively, a ratchet mechanism operated by a trigger or other manually operable mechanism may be provided on or near the restraining member. Such operation can be accomplished by a gas spring 222 of conventional conventional type. The lever 211a includes a propulsion control member 95 of the type described above when the fluid pressure chain or the flexible mechanical chain as described above is employed. In either case, a flexible fluid pressure pipe or a mechanically pushable / pullable cable allows the lever 211a to move freely around an axis 212. If necessary, the control member 95
It can be attached to the fixed part of the vehicle body regardless of the chain, and in that case, the restraint member 210 can be a single lever as shown in FIGS. 15 and 16 or two levers as shown in FIG. Can be supported. The brace bar 2 described and illustrated in connection with FIG.
13 and the gas spring 222 are also shown in FIGS.
It can also be used in the embodiment shown in. Additionally, in both embodiments, a flexible cable or rigid link can be provided on either lever 211, 211a or between lever 211 and the parking brake. Such links are shown in FIGS.
Is designated by reference numeral 223. In the example shown,
The propulsion control lever 95 is represented as being on one side 31 of the cab, while the loader control means 25 is arranged on the other side 32, but if necessary the position of the control member is rotatable. The position can be changed if the lever 211 that performs various operations can be accommodated. In practice, the link 223 is such that the vehicle parking brake is off when the restraint member 210 is in the driving position.
When the restraint member 210 is at the stop position, the parking brake is interlocked so as to work. In addition, although not shown, an interlock with the engine can be provided, in which case the engine can continue to run or be activated when the restraint member 210 is in the operating position. Furthermore, in either case, by providing an additional interlock that detects whether or not the driver is present, the engine can be activated only when the driver is sitting on the seat. When the restraint member 210 is moved from the operating position to the intermediate position, the interlock senses this and disables the engine. When the restraint member 210 is in the stop position, the interlock allows the engine to be started, in which case the engine will apply the parking brake by the action of the link 223 even when the driver is not in the seat. You can make it bootable if you do so. In the above embodiment, the ratchet teeth 218 are provided so that the position of the restraint member 210 can be adjusted according to the difference in the operating range depending on the physique of the driver.

Next, the cab will be described. Cab 2

In the case of one side 31, the presence / absence of the boom body and the stitch protection screen 30 constitute the entrance / exit prevention means. In the rear, the driver's cab is the engine compartment 34
Is defined by the front wall 34b. The space surrounded by the upper wall 34b and the lower portion of the shaft member makes it impossible to enter and leave the driver's cab, but on the other hand, the driver can see the lower rear part of the shaft member 42 from the driver's cab. ing. Inner plates 26a, 2 that define part of the cab
7a is integrated, and the side members 18,
The outer wall 161 of 19 continues integrally. In this embodiment, the inner plates 26a and 27a and the base 28a serving as the outer shell are formed by bending one plate into the shape shown in FIG. The roof 28 is welded to the plates 26a and 27a. if needed,
Instead of being molded from a single plate, the cab can be integrated with other structural parts of the vehicle body by welding.
In this way, the main structural members of the cab that make up the wall are
