The second upper surface 25c constitutes the left part of the upper surface of the grip 23. As shown in FIG. 8 and the like, the second upper surface 25c is inclined from the lower side to the upper side from the other side (left side) to the one side (right side). The upper surface 24c of the grip portion 24 and the upper surface (second upper surface) 25c of the operation portion 25 are connected in a mountain shape with a vertex 29 near the boundary between the grip portion 24 and the operation portion 25.

The second lower surface 25d constitutes the left part of the lower surface of the grip 23. As shown in FIG. 9 and the like, the second lower surface 25d is inclined from the upper side to the lower side from the other side (left side) to the one side (right side). The distance between the second upper surface 25c and the second lower surface 25d gradually increases from the other side toward the one side. The second lower surface 25d is connected to the lower surface 24d of the grip portion 24 and the lower surface of the extending portion 26.

The second left side surface 25e constitutes the left side surface of the grip 23. The upper portion of the second left side surface 25e is connected to the left portion of the second upper surface 25c. The lower portion of the second left side surface 25e is connected to the left portion of the second lower surface 25d. The boundary between the second left side surface 25e and the second upper surface 25c and the boundary between the second left side surface 25e and the second lower surface 25d are respectively curved.
The second back surface 25b constitutes the left part of the back surface of the grip 23. As shown in FIGS. 10 and 13, the second back surface 25b is a substantially flat surface that curves very gently. The upper edge of the second back surface 25b is connected to the second upper surface 25c. The lower edge of the second back surface 25b is connected to the second bottom surface 25d. The left edge portion of the second back surface 25b is connected to the second left side surface 25e. The right edge of the second back surface 25b is connected to the back surface 24b of the grip portion 24.

As shown in FIGS. 7 to 9, the extension portion 26 extends rearward from the lower portion of the grip portion 24 (the lower edge portion 24j of the curved surface 24a). The extending portion 26 extends from the other side (left side) to one side (right side), and is curved in a convex shape so as to bulge backward at a midway portion from the other side to the one side. ing. The other side portion (left portion) of the extending portion 26 extends to the other side (left side) of the curved surface 24a and the upright surface 24e, and the surface of the operating portion 25 ( The second surface) 25a. As shown in FIG. 9, in the extension portion 26, the extension width W1 on the other side (left side) is wider than the extension width W2 on the one side (right side) (W1>W2).

As shown in FIGS. 7 to 9, the grip 23 has a non-slip portion 28.
The anti-slip portion 28 is made of a material having an anti-slip function such as rubber. The coefficient of friction of the surface of the anti-slip portion 28 is larger than the coefficient of friction of the surface of the grip portion 24 (the surface of the portion where the anti-slip portion 28 is not provided). The anti-slip part 28 is configured by, for example, attaching a non-slip member such as a rubber plate to the surface of the grip part 24, or embedding the anti-slip member in the surface of the grip part 24. By providing the non-slip portion 28, it is possible to prevent the hand from slipping when the grip portion 24 is gripped and the operation lever 21 is operated. As a result, the operation lever 21 can be reliably operated, and since it is not necessary to firmly grip the grip portion 21, hand fatigue is unlikely to occur.

The anti-slip portion 28 is provided over (straddling) the surface of the grip portion 24 and the extension portion 26. Specifically, the anti-slip portion 28 is provided from the curved surface 24 a of the grip portion 24 to the surface of the extension portion 26. Hereinafter, of the anti-slip portion 28, the portion provided on the curved surface 24a of the grip portion 24 will be referred to as "anti-slip portion 28a", and the portion provided on the surface of the extending portion 26 will be referred to as "anti-slip portion 28b".

The anti-slip portion 28b is provided only on a portion located on one side (right side) of the surface of the extension portion 26, and is not provided on a portion located on the other side (left side). In other words, the anti-slip portion 28b is provided only on the side of the surface of the extending portion 26 opposite to the operation portion 25 side, and is not provided on the operation portion 25 side. The anti-slip portion 28a is not provided on the lower portion of the curved surface 24a of the grip portion 24 on the side of the operation portion 25. That is, the curved surface 24a of the grip portion 24 has a region 24a1 where the anti-slip portion 28b is not provided on the extending portion 26 side and the operating portion 25 side.

In other words, the anti-slip portion 28 is not provided on the thumb side when the grip portion 24 is held by the right hand. Specifically, the anti-slip portion 28a is not provided at a portion where the vicinity of the base of the thumb (the ball of the thumb) abuts when the grip portion 24 is gripped by the right hand. This prevents the anti-slip part 28 from interfering with the movement of the thumb that operates the operation switch provided on the operation part 25.

Next, the operation switch provided on the grip 23 will be described.
The grip 23 is provided with a plurality of operation switches. The plurality of operation switches are provided on the grip portion 24 and the operation portion 25, respectively.
As shown in FIG. 7 to FIG. 9 and the like, the operation unit 25 is provided with a plurality of operation switches 30, 31, 32. The plurality of operation switches 30, 31, 32 are provided on the surface (second surface) 25 a of the operation unit 25. Specifically, the plurality of operation switches 30, 31, 32 are provided on the upper surface (second surface) 25a of the operation unit 25. Although the operation switch is not provided below the second surface 25a, another operation switch may be provided as necessary.

The plurality of operation switches 30, 31, 32 are arranged in a range in which an operator who holds the grip 24 with his right hand can extend his thumb to operate. The operation switches 30 and 31 are seesaw switches. The operation switch 32 is a push button switch.
Specifically, the operation switch 30 is a shuttle switch (a forward/backward changeover switch of the traveling vehicle 1) that operates the transmission. Pressing the upper portion (“F” portion) of the operation switch 30 switches to forward driving, and pushing the lower portion of the operation switch 30 (“R” portion) switches to reverse driving.

The operation switch 31 is a pumper switch that drives the elevating device 4 to elevate the work device. Pushing the upper part of the operation switch 31 raises the working device, and pushing the lower part of the operation switch 31 lowers the working device.
The operation switch 32 is an automatic/manual switch for automatic shifting. By pressing the operation switch 32, the automatic shift mode and the manual shift mode are switched. In the automatic shift mode, the optimum vehicle speed stage is automatically selected by electronic control within the range of the vehicle speed stage set by the operator in advance. In the manual shift mode, the operator can manually switch the vehicle speed.

As shown in FIGS. 7 to 11 and the like, on the upright surface 24e of the grip portion 24, other operation switches 33, 34 different from the operation switches 30, 31, 32 provided on the operation portion 25 are provided. .. The other operation switches 33 and 34 provided on the upright surface 24e are push button switches. The operation switches 33 and 34 are main shift switches for switching the gear ratio. Pushing the operation switch 33 increases the gear ratio, and pushing the operation switch 34 decreases the gear ratio. The operation switch 33 and the operation switch 34 are arranged side by side in the vertical direction. Specifically, the operation switch 34 is arranged below and behind the operation switch 33. As shown in FIG. 8 and the like, the anti-slip portion 28 is provided over at least a range that overlaps the operation switches 33 and 34 in the vertical direction.

As shown in FIGS. 8 and 11, the region 24a1 where the anti-slip portion 28b is not provided is disposed below the operation switches 30, 31, 32 in the vertical direction. Accordingly, when the operation switch 30, 31, 32 is selected, the bulge of the base of the thumb can be slid on the surface of the region 24a1, and therefore the fingertip position of the thumb can be easily adjusted to the operation switch to be operated. Further, when the selected operation switch is operated (pressed), the bulge of the base of the thumb is located on the surface of the anti-slip portion 28b, so that the slip is suppressed, so that the operation switch can be reliably pressed.

As shown in FIG. 7 to FIG. 10 and the like, another operation switch 35 different from the operation switches 30, 31, 32 is provided on the surface surrounding the grip 23 and the periphery of the grip portion 24. .. The operation switch 35 is provided on at least one of the upper surface 24c, the lower surface 24d, the right side surface 24f, and the corner edge surface 24g of the grip portion 24.
In the case of the present embodiment, another operation switch 35 different from the operation switches 30, 31, 32 provided on the operation portion 25 is provided on the upper surface 24c of the grip portion 24. The other operation switch 35 provided on the upper surface 24c of the grip portion 24 is a push button switch, and is provided so as to project from the upper surface 24c. The operation switch 35 is a switch for switching permission/prohibition of swinging of the swinging body 22, and specifically, is a sub-shift check switch. By pressing the operation switch 35, the rocking body 22 can be rocked. When the oscillating body 22 is swung forward while pressing the operation switch 35, the sub-shift stage is shifted up, and when it is swung backward, the sub gear is shifted down. That is, the operation switch 35 is a switch for switching the permission/prohibition of the shift operation by the swing of the swing body 22.

The operation switch 35 is provided on the upper surface 24c of the grip portion 24. Since the upper surface 24c of the grip portion 24 is provided above the curved surface 24a, it can be said that the operation switch 35 is provided above the curved surface 24a. The operation switch 35 is provided at a position near the operation unit 25 on the upper surface 24c. Specifically, as shown in FIG. 8, the operation switch 35 includes a side edge on one side (first side edge 24h1) and a side edge on the other side (second side edge 24h2) of the grip portion 24. It is provided at a position closer to the operating portion 25 (a position closer to the left) than the intermediate position 24M between the two. The intermediate position 24M between the side edge on one side and the side edge on the other side is the distance between the first side edge 24h1 and the second side edge 24h2 in the width direction of the armrest 15. Is an intermediate position in the widest portion (the lower edge portion 24j of the curved surface 24a).

As described above, the upper surface 24c of the grip portion 24 and the upper surface (second upper surface) 25c of the operation portion 25 are connected in a mountain shape with the vertex 29 near the boundary between the grip portion 24 and the operation portion 25. As shown in FIG. 8, the operation switch 35 is provided between the side edge on one side (first side edge 24h1) and the side edge on the other side (second side edge 24h2) of the grip portion 24. It is provided at a position closer to the apex 29 than the position 24M (position on the left side).

As shown in FIG. 10, the operation switch 35 is arranged on an extension line La extending from the surface 25a (second surface 25a) of the operation portion 25 to the grip portion 24 side. This allows the operator to intuitively grasp the position of the operation switch 35 while holding the grip portion 24.
As shown in FIGS. 12 and 13, another operation switch 36 different from the operation switches 30, 31, 32 provided on the operation unit 25 is also provided on the back surface 24 b of the grip portion 24. The operation switch 36 provided on the back surface 24b of the grip portion 24 is a push button switch. The operation switch 36 is a shuttle restraint switch that switches whether the operation of the operation switch 30 which is a shuttle switch is permitted or not. By operating the operation switch (shuttle switch) 30 while pressing the operation switch (shuttle restraint switch) 36, it is possible to switch between forward and reverse.

As shown in FIGS. 14 and 15, the operation switch 36 does not protrude from the back surface 24b. Therefore, it is possible to prevent the operation switch 36 from impairing the operational feeling when the operator grasps the grip portion 24 and operates the operation lever 21.
As shown in FIGS. 12 to 15, the back surface 24b of the grip portion 24 is provided with a guide recess 37 for guiding a finger toward the operation switch 36. The operation switch 36 is operated by the index finger of the right hand while the grip portion 24 is held by the right hand. Therefore, the guide recess 37 guides the index finger of the right hand holding the grip 24 toward the operation switch 36.

The guide recess 37 is formed so as to be recessed from the back surface 24b of the grip portion 24. The guide recess 37 has an inclined surface 37a whose depth changes as it approaches the operation switch 36. As shown in FIGS. 14 and 15, the inclined surface 37 a has a dent depth that gradually increases as it approaches the operation switch 36. Therefore, by sliding the finger along the inclination of the guide recess 37, the finger is naturally guided to the operation switch 36. The inclined surface 37a may have a depth that is gradually reduced as it approaches the operation switch 36.

The outer edge portion of the guide recess 37 forms a closed region on the back surface 24b of the grip portion 24. That is, the outer edge portion 37b of the guide recess 37 is inside the outer edge portion (upper edge portion, lower edge portion, left edge portion, right edge portion) of the back surface 24b and does not reach the outer edge portion. As a result, on the back surface 24b of the grip portion 24, a non-recessed area 24p is formed around the closed area formed by the outer edge portion 37b of the guide recess 37. The region 24p that is not recessed surrounds the periphery (outside) of the outer edge portion 37b of the guide recess 37.

The operation switch 36 is arranged at the upper corner portion 24n of the back surface 24b of the grip portion 24 opposite to the driver's seat 10 (right side). The upper corner portion 24n is located on the back side of the corner edge portion 24k of the curved surface 24a of the grip portion 24 and is connected to the corner edge surface 24g. The inclined surface 37a extends in a fan shape from the vicinity of the upper corner portion 24n.
As shown in phantom in FIG. 13, the guide recess 37 may be provided with a projection or groove 37c extending in an arc shape. The protrusion or groove 37c is provided in a region near the center of the guide recess 37 (a region between the outer edge portion on the operation switch 36 side and the outer edge portion on the opposite side to the operation switch 36). The protrusion or groove 37c is formed in an arc shape centered on the operation switch 36. Thus, when the fingertip is placed near the center of the guide recess 37, the protrusion or the groove 37c is touched to obtain the sensation that the operation switch 36 is located at the center of the arc and to grasp the position of the operation switch 36. You can

As shown in FIGS. 2 to 5 and FIGS. 16 to 18, a plurality of operation tools are arranged in the operation tool placement section 19. Hereinafter, the plurality of operation tools arranged in the operation tool disposition unit 19 will be referred to as a “front operation tool group 60”. In FIG. 17, the front operation tool group 60 is shown surrounded by an imaginary line designated by reference numeral 60. The front operation tool group 60 is arranged on the upper surface 16 a of the main body 16 and in front of the rear operation tool group 40. The front operation tool group 60 and the rear operation tool group 40 are provided on the same surface (upper surface 16a). The operation tools included in the front operation tool group 60 arranged in the operation tool arranging section 19 are operation tools that are operated more frequently than the operation tools included in the rear operation tool group 40 covered by the elbow rest section 18. ..

The operation tool placement portion 19 is provided at a position closer to the front of the armrest 15. Specifically, the operation tool placement portion 19 is provided behind the swing operation portion 17 and in front of the elbow rest portion 18. In other words, the operation tool placement section 19 is provided between the swing operation section 17 and the elbow rest section 18. The operation tool placement portion 19 is an upper surface of a portion of the upper surface 16 a of the main body 16 located between the swing operation portion 17 and the elbow rest portion 18.

As shown in FIGS. 4 and 5, the operation tool disposition portion 19 is provided at a lower position than the upper surface 20 a of the pedestal 20 and the upper surface 18 a of the elbow rest portion 18. That is, the height of the operation tool placement portion 19 is lower than the height of the pedestal 20 (the height from the upper surface 16a) and the height of the upper surface 18a of the elbow rest portion 18. In other words, the operation tool placement portion 19 is provided so as to be recessed with respect to the upper surface 20a of the pedestal 20 and the upper surface 18a of the elbow rest portion 18. Further, the upper surface of the operation tool disposing portion 19 is inclined so as to move downward as it goes forward.

As shown in FIG. 4, the front operation tool group 60 is arranged below a virtual straight line L1 that connects the upper end of the pedestal 20 and the front end of the upper surface 18a of the elbow rest 18. That is, the front operation tool group 60 does not project upward from the virtual straight line L1. The front operation tool group 60 is arranged below an extension line L2 that extends the upper surface 18a of the elbow rest 18 to the pedestal 20. That is, the front operation tool group 60 does not project upward from the extension line L2.

The upper end of the pedestal 20 is higher than the upper surface 18a of the elbow rest 18. Therefore, the virtual straight line L1 is inclined so as to move upward as it goes forward. Further, since the upper surface 18a of the elbow rest portion 18 is inclined so as to move downward as it goes from the front to the rear, the extension line L2 is also inclined so as to move upward as it goes to the front. In addition, the vertical distance between the upper surface of the operation tool placement portion 19 and the virtual straight line L1 increases as it goes forward.

The front operation tool group 60 includes a first operation tool group 60A and a second operation tool group 60B. In FIG. 18, the first operation tool group 60A is surrounded by a virtual line with a reference numeral 60A, and the second operation tool group 60B is surrounded with a virtual line with a reference numeral 60B.
