The attachment structure 350 for attaching the left side frame structure 330 to the vehicle body frame 36 will be described below with reference to FIGS. 3 to 6. The mounting structure 350 particularly has a structure for sealing the rear pillar 33R and the left door 35L when the left door 35L is closed, and includes the pillar cover 37 and the water blocking member 40 (see FIGS. 4 to 6). It consists of
FIG. 3 shows an example of the cross-sectional shape of the rear pillar 33R and the left door 35L in the A1-A1 plane of the present embodiment in a region R1 behind the cab 3 shown in FIG. The A1-A1 plane is a plane in which the rear pillar 33R and the pillar cover 37 are in contact with each other. As described above, in the present embodiment, the rear pillar 33R is formed to have an odd-shaped cross section. The rear pillar 33R has a first pillar surface (hereinafter also referred to as a first front surface in the connection portion between the rear pillar 33R and the pillar cover 37) 331 facing the front of the forklift 1 and a second pillar surface (hereinafter, the rear pillar 33R and the pillar cover 37 also refers to the second front surface) 332, and the third pillar surface 333 and the fourth pillar surface facing the left of the forklift 1 (hereinafter referred to as the second pillar surface 33R and the pillar cover 37, respectively) 1, also referred to as the second left side) 334). The first pillar surface 331 is a surface formed in front of the second pillar surface 332, and the third pillar surface 333 is a surface formed on the right side of the fourth pillar surface 334, that is, on the driver's cab 3 side. .

  The rear pillar 33R has a step-like cross-sectional shape on the left side surface of the forklift 1 by the first to third pillar surfaces 331, 332, and 333. The stepped cross-sectional shape can be called a step. The cross sectional shape of the rear pillar 33R is not limited to the shape shown in FIG. 3, and the area of the cross surface of the rear pillar 33R facing the outside of the cab 3 is made by the first to third pillar surfaces 331, 332, 333. It may be formed in steps.

  In addition, since the left side frame structure 330 has a shape along the peripheral edge of the left door 35L as described above, the first pillar surface 331 and the second pillar surface 332 are provided in the region R2 which is a connecting portion with the upper roof 32. Is a surface facing downward of the forklift 1. In addition, in the region R3 which is the front of the vehicle body of the forklift 1, the first pillar surface 331 and the second pillar surface 332 are surfaces facing the rear of the forklift 1.

  The pillar cover 37 looks good in the rear pillar 33R having a stepped cross section on the left side surface of the forklift 1 as described above, and the vehicle body frame 36 not having the stepped cross section on the left side surface (frame surface) of the forklift 1 It is a member for attachment. The upper portion of the pillar cover 37 is formed in a cross-sectional shape corresponding to the modified cross-section of the rear pillar 33R so as to cover the rear pillar 33R from the outside. That is, the cross section at the upper portion of the pillar cover 37 has a cross-sectional shape similar to the shape of the modified cross-section of the rear pillar 33R. The lower portion of the pillar cover 37 is formed in a cross-sectional shape corresponding to the shape of the vehicle body frame 36 in which a stepped cross section is not formed on the left side surface of the forklift 1 so as to cover the vehicle body frame 36 from the outside. In other words, the pillar cover 37 is a member that gradually changes its shape from the deformed cross-sectional shape of the rear pillar 33R to the left side planar shape of the vehicle body frame 36. The pillar cover 37 is attached to the rear pillar 33R or the vehicle body frame 36 by a bolt or the like.

  The seal member 39 described above is provided on the periphery of the left door 35L. The seal member 39 has a first seal portion 391 and a second seal portion 392. The second seal portion 392 is not provided on the entire periphery of the door periphery, but is provided on the connection portion between the rear pillar 33R and the pillar cover 37. That is, the second seal portion 392 of the seal member 39 is provided at least at a portion (range) in contact with the water blocking member 40 described later. The first seal portion 391 abuts on the second pillar surface 332 and the third pillar surface 333 of the rear pillar 33R when the left door 35L is closed. The second seal portion 392 abuts on the first pillar surface 331 and the third pillar surface 333 of the rear pillar 33R when the left door 35L is closed.

  FIG. 4A is an enlarged view of the region R1 shown in FIG. 2, that is, the vicinity of the attachment portion between the rear pillar 33R and the pillar cover 37. FIG. 4 shows a range in which the second seal portion 392 of the left door 35L abuts when the left door 35L is closed. The pillar cover 37 covers the rear pillar 33R from the outside. For this reason, as shown to a figure, a level | step difference arises in the surface of the pillar cover 37, and the 1st pillar surface 331 of the rear pillar 33R, the 2nd pillar surface 332, the 3rd pillar surface 333, and the 4th pillar surface 334. In the present embodiment, a water blocking member 40 is provided at this stepped portion as shown in FIG. 4 (b). Hereinafter, the water blocking member 40 will be described in detail.

  FIG. 5 is a perspective view showing the appearance of the water blocking member 40, and FIG. 5 (a) shows the appearance of the surface of the water blocking member 40, and FIG. 5 (b) is the appearance from the top of the water blocking member 40. 5C shows the appearance of the back surface of the water blocking member 40. FIG. In the present specification, the surface of the water shutoff member 40 in contact with the seal member 39 of the left door 35L is referred to as the front surface, and the surface of the water shutoff member 40 in contact with the rear pillar 33R is referred to as the back surface. In the following description, the first pillar surface 331, the second pillar surface 332, the third pillar surface 333, and the fourth pillar surface 334 of the rear pillar 33R are substantially parallel to the vertical direction of the forklift 1. . That is, it is assumed that it is perpendicular to the bottom of the cab 3.

  The water blocking member 40 is a member that fills in the step of the connection portion between the rear pillar 33R and the pillar cover 37, in other words, a member that gradually reduces the step and connects smoothly. The water blocking member 40 is provided so as to fill the steps between the first pillar surface 331, the third pillar surface 333, the second pillar surface 332, and the pillar cover 37 of the rear pillar 33R. The water blocking member 40 has a substantially L-shaped cross section, and the cross section gradually spreads from the upper edge to the lower edge, and the surface of the water blocking member 40 is smoothly connected from the surface of the rear pillar 33R to the surface of the pillar cover 37 It has a shape.

  The water blocking member 40 faces the front-rear direction of the forklift 1, and the back surface faces the first portion (front surface member) 41 in contact with the first pillar surface 331 of the rear pillar 33R; A second portion (left side member) 42 in contact with the three pillar surface 333 and an attachment portion 43 provided below the first portion 41 and the second portion 42 and inserted into a gap between the rear pillar 33R and the pillar cover 37. And. The first portion 41 and the second portion 42 are connected along the vertical direction of the forklift 1. The first portion 41 and the second portion 42 are connected at a predetermined angle θ1 on a plane orthogonal to the vertical direction of the forklift 1. The predetermined angle θ1 formed by the first portion 41 and the second portion 42 is an angle formed by the first pillar surface 331 and the third pillar surface 333 of the rear pillar 33R on a plane orthogonal to the vertical direction of the forklift 1. In FIGS. 3 and 4, the case where the angle formed by the first pillar surface 331 and the third pillar surface 333 is at right angles is shown as an example. In this case, the predetermined angle θ1 formed by the first portion 41 and the second portion 42 is a right angle.

  The first portion 41 has a first side surface 411 on the front side and a second side surface 412 on the back side. The first side surface 411 has a predetermined inclination with respect to the vertical direction of the forklift 1 as described later. The second side surface 412 is substantially parallel to the first pillar surface 331 of the rear pillar 33R. For this reason, the first thickness between the first side surface 411 and the second side surface 412 is different at each position in the vertical direction of the forklift 1. In the present embodiment, the first thickness between the first side surface 411 and the second side surface 412 at the lower end of the first portion 41, that is, the boundary connected to the attachment portion 43 is the first pillar surface 331 of the rear pillar 33R. And the step produced by the pillar cover 37 are substantially equal. The first thickness decreases as the distance from the mounting portion 43 increases, that is, the upper portion of the first portion 41.

  The second portion 42 has a third side surface 421 on the front side and a fourth side surface 422 on the back side. The third side surface 421 has a predetermined inclination with respect to the vertical direction of the forklift 1 as described later. The fourth side surface 422 is substantially parallel to the third pillar surface 333 of the rear pillar 33R. For this reason, the second thickness between the third side surface 421 and the fourth side surface 422 is different at each position in the vertical direction of the forklift 1. In the present embodiment, the second thickness between the third side surface 421 and the fourth side surface 422 at the lower end of the second portion 42, that is, the boundary connected to the attachment portion 43 is the third pillar surface 333 of the rear pillar 33R. And the step produced by the pillar cover 37 are substantially equal. The second thickness decreases as the distance from the mounting portion 43 increases, that is, the upper portion of the second portion 42.

The mounting portion 43 enters the gap formed between the first pillar surface 331 and the second pillar surface 332 of the rear pillar 33R and the inner surface of the pillar cover 37, thereby providing the water blocking member 40 to the rear pillar 33R and the pillar cover 37. Attach. Therefore, the thickness of the attachment portion 43 is smaller than the first thickness at the lower end of the first portion 41 and the second thickness at the lower end of the second portion 42. The mounting portion 43 has a first mounting portion 431 located below the first portion 41 and a second mounting portion 432 located below the second portion 42. The first attachment portion 431 and the second attachment portion 432 are connected so as to form a predetermined angle θ1 which the first portion 41 and the second portion 42 have. The thickness of the attachment portion 43 has a burr portion 433 that is larger at the lower side than at the upper side (the first portion 41 and the second portion 42 side). For this reason, when the water blocking member 40 is attached and the mounting portion 43 is inserted into the gap between the rear pillar 33R and the pillar cover 37, the burred portion 433 is fixed to the back surface of the upper end of the pillar cover 37 (see FIG. 6 (b)). For this reason, by inserting the attachment portion 43 into the gap between the rear pillar 33R and the pillar cover 37, it is possible to attach the water blocking member 40 without dropping off without using an adhesive or the like.
In addition, the attaching part 43 does not need to be equipped with the burred part 433 mentioned above. In this case, as shown in FIG. 6C, the attachment portion 43 is inserted into the gap between the rear pillar 33R and the pillar cover 37, and the water blocking member 40 is attached.
Further, as shown in FIG. 5 (d), the water blocking member 40 may not have the attachment portion 43. In this case, the water blocking member 40 may be attached using an adhesive or the like.

  FIG. 4 (b) shows a state in which the water blocking member 40 having the above-mentioned shape is attached to the pillar cover 37. The first pillar surface (first front surface) 331 of the rear pillar 33R is connected to the surface of the pillar cover 37 on the vehicle front side via the first side surface 411 of the first portion 41 of the water blocking member 40. The third pillar surface 333 (first left surface) of the rear pillar 33R is connected to the left surface of the pillar cover 37 via the third side surface 421 of the second portion 42 of the water blocking member 40. The first thickness of the first side surface 411 and the second side surface 412 of the water blocking member 40 decreases as the distance from the mounting portion 43 increases, that is, as the distance from the pillar cover 37 increases. Similarly, the second thickness of the third side surface 421 and the fourth side surface 422 of the water blocking member 40 decreases as the distance from the mounting portion 43 increases, that is, as the distance from the pillar cover 37 increases. Therefore, unlike the case where the water blocking member 40 is not attached as shown in FIG. 4A and a step is generated between the rear pillar 33R and the pillar cover 37, the rear pillar 33R and the pillar cover 37 Thus, it can be continuously connected along the periphery of the left door 35L, that is, it can abut without any gap. Therefore, according to the shape along the peripheral edge of the left door 35L, the ratio of the change in the first thickness and the change in the second thickness along the vertical direction may be determined.

  FIG. 6 is a schematic view showing an abutting state of the rear pillar 33R and the seal member 39 of the left door 35L when the left door 35L is closed. 6 (a) shows a state in which the water blocking member 40 is not attached as shown in FIG. 4 (a), and FIG. 6 (b) shows that the water blocking member 40 is attached as shown in FIG. 4 (b). Show the condition. 6 schematically shows the contact state between the third pillar surface 333 of the rear pillar 33R and the first seal portion 391 of the seal member 39 when viewed from the rear of the forklift 1.

  As shown in FIG. 6A, when the water blocking member 40 is not attached, a step is generated between the rear pillar 33R and the pillar cover 37, whereby the left door 35L is closed. There are places where the first seal portion 391 can not abut on the rear pillar 33R. That is, a space S is generated between the first seal portion 391, the rear pillar 33R, and the pillar cover 37. The width of the space S is smaller as it is on the upper side in the vertical direction.

  On the other hand, as shown in FIG. 6B, when the water blocking member 40 is attached, no step is generated between the rear pillar 33R and the pillar cover 37. When the water blocking member 40 formed so as to fill the space S shown in FIG. 6A is attached, the first seal portion 391 and the third side surface of the water blocking member 40 are closed when the left door 35L is closed. 421 contacts. That is, when the water blocking member 40 is formed such that the second thickness between the third side surface 421 and the fourth side surface 422 changes in accordance with the change in the width of the space S, the first seal portion 391 And the third side surface 421 and the third pillar surface 333 of the water blocking member 40 can be in close contact with each other.

In addition, when the water blocking member 40 is not attached, a step is also generated between the first pillar surface 331 of the rear pillar 33R and the pillar cover 37, so that the same as the space S as shown in FIG. Space also occurs in the first pillar surface 331. When the first thickness between the first side surface 411 and the second side surface 412 of the water blocking member 40 is changed so as to fill the space, the sealing member The second seal portion 392 and the first side surface 411 of the water blocking member 40 can be in close contact with each other (see FIG. 4B).
Thereby, the seal member 39 can be in close contact with each other without generating a space between the rear pillar 33R and the pillar cover 37.
In addition, since the right side of the forklift 1 also has the same structure as the left side structure described above, when the right door 35R is closed, the seal member can be closely contacted without creating a space between the rear pillar 33R and the pillar cover. .
In addition, the second seal portion 392 of the seal member 39 prevents the water blocking member 40 from pushing the lip portion of the first seal portion 391 of the seal member 39 forward when the left door 35L and the right door 35R are closed. So you can keep the water stop function.

According to the first embodiment described above, the following effects can be obtained.
(1) The forklift 1 includes a vehicle body frame 36 having a frame surface corresponding to the peripheral shape of the left door 35L, and a rear pillar 33R having a cross-sectional shape that supports the roof 32 covering the cab 3, and the peripheral shape of the left door 35L. And a mounting structure 350 for attaching the left side frame structure 330 to the vehicle body frame 36. The mounting structure 350 has a pillar cover 37 and a water blocking member 40. The pillar cover 37 is a cover that covers the connection between the vehicle body frame 36 and the rear pillar 33R, and the upper end has a cross-sectional shape similar to that of the rear pillar 33R, and from the upper end to the lower end, The irregular cross-sectional shape is gradually deformed to the body frame 36 frame surface. The water blocking member 40 is formed at a connection portion between the rear pillar 33R and the pillar cover 37, and has a shape connecting the surface of the rear pillar 33R and the surface of the pillar cover 37. When the left door 35L is closed, It abuts on the seal member 39. Therefore, the step between the surface of the rear pillar 33R and the surface of the pillar cover 37 can be filled with the water blocking member 40, and the connection portion between the rear pillar 33R and the pillar cover 37 can be smoothly connected with the peripheral shape of the left door 35L. When the left door 35L is closed by providing the second seal portion 392 of the seal member 39 at least in a portion (range) in contact with the water blocking member 40, the lip portion of the first seal portion 391 of the seal member 39 is on the front side. It can prevent being pushed. As a result, while attaching the rear pillar 33R to the vehicle body frame 36 in good appearance and closing the left door 35L, the first seal portion 391 of the seal member 39 disposed along the periphery of the left door 35L is the rear pillar 33R, the water blocking member 40 and the pillar cover 37 can be abutted without any gap. Thereby, dust, dirt, water and the like from the outside can be prevented from entering the inside of the cab 3. In addition, since the right side of the forklift 1 also has the same configuration as the left side, dust, dust, water and the like from the outside can be prevented from entering the inside of the cab 3 also on the right side of the forklift 1.

(2) The water blocking member 40 is thickened upward from the connection portion between the rear pillar 33R and the pillar cover 37 according to the space enclosed by the surface of the rear pillar 33R, the surface of the pillar cover 37 and the peripheral edge of the left door 35L. Becomes smaller. That is, by gradually reducing the thickness of the water blocking member 40 upward, the level difference between the upper end of the pillar cover 37 and the rear pillar 33R is eliminated. Therefore, when the left door 35L is closed, the first seal portion 391 of the seal member 39 disposed along the peripheral edge of the left door 35L can contact the rear pillar 33R, the water blocking member 40 and the pillar cover 37 without a gap. Thereby, dust, dirt, water and the like from the outside can be prevented from entering the inside of the cab 3. Since the right side of forklift 1 also has the same configuration as the left side, dust, dirt, water, etc. from the outside can be prevented from entering inside cab 3 even when right door 35R of forklift 1 is closed. Can.

(3) The water blocking member 40 has a first portion 41 in contact with the first pillar surface 331 of the rear pillar 33R and a second portion 42 in contact with the third pillar surface 333 of the rear pillar 33R. The first thickness of the first portion 41 and the second thickness of the second portion 42 decrease as the distance from the pillar cover 37 upward increases. When the left door 35L of the forklift 1 is closed, the first portion 41 and the second portion 42 abut on a seal member 39 disposed along the periphery of the left door 35L.

In addition, since the right side of the forklift 1 also has the same configuration as the left side, the sealing degree of the cab 3 when the right door 35R of the forklift 1 is closed can be improved.

-Second embodiment-
A water blocking member according to a second embodiment will be described with reference to the drawings. In the following description, the same components as those of the first embodiment are denoted by the same reference numerals and differences will be mainly described. The points that are not particularly described are the same as in the first embodiment. In the present embodiment, the shape of the water blocking member is different from the shape of the water blocking member 40 of the first embodiment.

  FIG. 7 is a perspective view showing the external appearance of the water blocking member 50 of the second embodiment, and FIG. 7 (a) shows the external appearance of the surface of the water blocking member 50, and FIG. The appearance from the top of the member 50 is shown, and FIG. 7C shows the appearance of the back surface of the water blocking member 50. Also in the second embodiment, the surface of the water shutoff member 50 in contact with the seal member 39 of the left door 35L is referred to as the surface, and the surface of the water shutoff member 50 in contact with the rear pillar 33R is referred to as the back surface. Also in the second embodiment, the structure on the left side of the cab 3 of the forklift 1 is mainly performed, but the same applies to the structure on the right side of the cab 3 unless otherwise specified.

  The water blocking member 50 is provided below the first portion 41 facing the front-rear direction of the forklift 1, the second portion 51 facing the left-right direction, and the first portion 41 and the second portion 51. And a mounting portion 43 connected to the second portion 51. The first portion 41 and the attachment portion 43 are the same as the first portion 41 and the attachment portion 43 of the water blocking member 40 of the first embodiment. As in the first embodiment, the first portion 41 and the second portion 51 are connected at a predetermined angle θ1 on a plane orthogonal to the vertical direction of the forklift 1.

The second portion 51 of the water blocking member 50 has a third side surface 521 on the front surface side and a fourth side surface 522 on the back surface side. The second thickness of the third side surface 521 and the fourth side surface 522 is the same as the second thickness of the third side surface 421 and the fourth side surface 422 in the first embodiment. That is, at the lower end of the second portion 51, that is, at the boundary connected to the attachment portion 43, the step difference substantially caused by the third pillar surface 333 of the rear pillar 33R and the pillar cover 37 is substantially equal. The second thickness decreases as the distance from the mounting portion 43 increases, that is, the upper portion of the second portion 51.
Also in the water blocking member 50 of the second embodiment, the mounting portion 43 may not have the burr portion 433. Further, as shown in FIG. 7D, the water blocking member 50 may not have the attachment portion 43.

  Unlike the second portion 42 of the water blocking member 40 of the first embodiment, the second portion 51 is formed with a notch. Specifically, an end 52 of the second portion 51 on the rear side of the forklift 1 has a predetermined notch angle θ2 with respect to the vertical direction of the forklift 1. Thus, the width of the fourth side surface 522 of the second portion 51, that is, the length along the front-rear direction of the forklift 1 from the boundary 523 connected to the first portion 41 to the end 52 Decrease with increasing distance along the vertical direction.

  FIG. 8 is an enlarged view of the region R1 shown in FIG. 2, that is, the vicinity of the attachment portion of the rear pillar 33R and the pillar cover 37 when the water blocking member 50 of the second embodiment is attached. Also in the present embodiment, the first thickness of the first portion 41 and the second thickness of the second portion 51 have the same shape as the water blocking member 40 of the first embodiment. Therefore, when the left door 35L is closed, the seal member 39 provided along the periphery of the left door 35L and the first side surface 411 and the second portion 51 of the first portion 41 of the water blocking member 50 are provided. Close to the three sides 521. Furthermore, the second portion 51 is formed with the above-described notch. Thereby, the moisture from above the third pillar surface 333 of the rear pillar 33R is transmitted along the inclined surface of the end 52 cut at the notch angle θ2, and the vehicle body of the forklift 1 as shown by arrow A in FIG. It is led down. For this reason, it is suppressed that the moisture from the upper part of the third pillar surface 333 of the rear pillar 33R is accumulated at the upper end of the second portion 51 and transmitted to the inside of the cab 3 along the upper end of the first portion 41.

According to the second embodiment described above, in addition to the effects obtained by the first embodiment, the following effects can be obtained.
The first portion 41 is in contact with a first pillar surface 331 facing in the front-rear direction of the forklift 1 of the rear pillar 33R, and the second portion 51 is a third pillar surface 333 facing in the left-right direction of the forklift 1 of the rear pillar 33R. Abut on. The width of the second portion 51 from the boundary 523 between the first portion 41 and the second portion 51 decreases with an increase in the distance from the pillar cover 37 upward. As a result, moisture from above the third pillar surface 333 of the rear pillar 33R is collected at the upper end of the second portion 51, and is prevented from infiltrating the inside of the cab 3 along the upper end of the first portion 41.

The following modifications are also within the scope of the present invention, and one or more of the modifications can be combined with the above-described embodiment.
