Description

[Technical Field]

[0001] The present invention relates to a head guard for an industrial vehicle, an industrial vehicle, and a roof member for an industrial vehicle. [Background technology]

[0002] Patent Document 1 discloses an industrial vehicle that includes an assembly plate having an opening, a roof supported within the opening of the assembly plate, and a circumferential frame elastically connected to the roof. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] U.S. Patent No. 9,481,555 Summary of the Invention [Problem to be solved by the invention]

[0004] Industrial vehicles may be used or stored in environments where they are subject to rainfall, such as outdoors, where liquid may drip onto the head guard from above. In such cases, liquid may accumulate on the horizontally extending head guard. If the industrial vehicle is moved with liquid pooled on it, the liquid may drip onto the user riding in the industrial vehicle, potentially reducing operability and comfort. Furthermore, liquid pooled on the transparent head guard may act as a lens, concentrating sunlight that passes through the liquid and the head guard, potentially causing parts of the industrial vehicle to become hot. Therefore, there has been a need for a head guard for an industrial vehicle, an industrial vehicle having such a head guard, and a roof member for an industrial vehicle that has a structure that is resistant to liquid pooling and can adequately ensure visibility above.

[0005] Therefore, an object of the present invention is to provide a head guard for an industrial vehicle, an industrial vehicle, and a roof member for an industrial vehicle that has a structure that makes it difficult for liquid to accumulate and that can properly ensure visibility above. [Means for solving the problem]

[0006] A head guard for an industrial vehicle according to one aspect of the present invention is provided directly above the driver's seat of an industrial vehicle having a loading device capable of loading cargo, and comprises a protruding portion that protrudes upward, and a flat portion that is provided on the loading device side of the protruding portion and above the driver's seat, and both the protruding portion and the flat portion are inclined toward either the front or rear in the fore-and-aft direction connecting the loading device and the driver's seat, and at least the flat portion is transparent to visible light.

[0007] In this industrial vehicle head guard, both the protruding portion and the flat portion are inclined toward either the front or rear direction, so that liquid that falls on the head guard is guided in the inclined direction. This reduces the likelihood of liquid accumulating on the protruding portion and the flat portion, reducing the likelihood of liquid spilling on the user riding the forklift 1 even when the forklift 1 is being moved, ensuring appropriate operability and comfort. Furthermore, sunlight that passes through the liquid and the head guard is concentrated, preventing parts of the industrial vehicle from becoming too hot. Furthermore, the user can see above through the flat portion, where liquid is less likely to accumulate. Furthermore, by providing the protruding portion directly above the driver's seat, the comfort of the user seated in the driver's seat can be improved. Furthermore, by providing the flat portion closer to the loading device than the protruding portion, the flat portion can be positioned between the user's viewpoint and the loading device when it has moved upward, ensuring appropriate visibility above. Therefore, this industrial vehicle head guard has a structure that prevents liquid from accumulating and ensures appropriate visibility above.

[0008] In one embodiment of the head guard for an industrial vehicle, the length of the protruding portion in the front-rear direction is longer than the length of the flat portion. In this case, the protruding portion is provided directly above the driver's seat, so that the comfort of a user sitting in the driver's seat can be more appropriately ensured.

[0009] In one embodiment of the head guard for an industrial vehicle, a portion of the flat plate portion may be located at a position that intersects with a line connecting the position of the bottom of the loading device or the load that can be loaded on the loading device and the estimated position of the viewpoint of a user who can sit in the driver's seat. In this case, the user sitting in the driver's seat can visually confirm the position of the bottom of the loading device and the position of the bottom of the load loaded on the loading device through the flat plate portion. This allows for appropriate visibility of the space above the driver's seat, such as the loading device, the load that can be loaded on the loading device, and the space below the load.

[0010] In one embodiment of the head guard for an industrial vehicle, the protruding portion may have a central portion protruding upward in the left-right direction intersecting the front-rear direction. In this case, for example, the amount of liquid that falls on the protruding portion and flows to the flat plate portion can be reduced, resulting in a structure that is less likely to collect liquid and ensuring appropriate visibility above.

[0011] According to one embodiment, the head guard for an industrial vehicle further includes a water guide portion provided at the lower end of the protruding portion and the flat portion in the inclined direction, extending in a left-right direction intersecting the front-rear direction, and capable of guiding water in the left-right direction. The water guide portion may have a drain outlet formed in at least one end in the left-right direction. In this case, the head guard can drain liquid flowing from the protruding portion and the flat portion through the drain outlet formed in at least one of the left and right directions. This reduces the possibility of liquid accumulating in the center of the head guard in the left-right direction, thereby ensuring appropriate visibility and comfort for the user.

[0012] The head guard for an industrial vehicle according to one embodiment may further include another water guide portion that is provided on at least one of both ends of the protruding portion and the flat plate portion in a left-right direction intersecting the front-rear direction, extends in the front-rear direction, and can guide water in the front-rear direction. In this case, the another water guide portion can receive liquid flowing in the left-right direction from the protruding portion and the flat plate portion and guide the water in the front-rear direction. This reduces the possibility of liquid dripping on at least one of both ends of the head guard in the left-right direction, thereby ensuring appropriate visibility and comfort for the user.

[0013] According to one embodiment, the head guard for an industrial vehicle further includes an extension portion connected to the protruding portion and the flat plate portion, provided at at least one of both ends of the protruding portion in a left-right direction intersecting the front-to-rear direction, and extending in a flat plate shape along the flat plate portion while inclined together with the protruding portion and the flat plate portion toward either the front or rear in the front-to-rear direction, and a water guide portion extending in the front-to-rear direction on the extension portion and the flat plate portion and capable of guiding water in the front-to-rear direction. In this case, the water guide portion can receive liquid flowing in the left-to-right direction from the protruding portion via the extension portion and liquid flowing in the left-to-right direction from the flat plate portion and guide the water in the front-to-rear direction. This reduces the possibility of liquid dripping on at least one of both ends of the head guard in the left-to-right direction, thereby ensuring appropriate visibility and comfort for the user.

[0014] According to one embodiment, the head guard for an industrial vehicle further includes a flat support member that supports the protruding portion and the flat portion from below, and the protruding portion and the flat portion may be attached to the support member. In this case, the protruding portion and the flat portion are attached to the flat support member from below, which prevents unevenness in the structure supporting the protruding portion and the flat portion from affecting the protruding portion and the flat portion. This prevents liquid from accumulating in parts of the protruding portion and the flat portion, and improves the attachability and sealing properties of the protruding portion and the flat portion.

[0015] In one embodiment of the head guard for an industrial vehicle, the protruding portion and the flat portion each constitute a part of a roof member integrally molded from resin, the support member is a frame-shaped member having at least one opening extending vertically therethrough, and the roof member may be supported by covering the opening of the support member and having its outer edge fixed to the support member. In this case, the support member has a frame shape, and the protruding portion and the flat portion cover the opening. This prevents the support member from narrowing the upward field of view of a driver riding in the industrial vehicle.

[0016] In one embodiment, the head guard for an industrial vehicle may further include a bar member fixed to the support member, the bar member extending across at least one opening of the support member in a left-right direction that intersects with the front-rear direction. In this case, even if an impact is applied to the protruding portion and the flat plate portion by an object falling from above, the deflection of the protruding portion and the flat plate portion can be further reduced.

[0017] In one embodiment of the head guard for an industrial vehicle, a coating layer may be provided on at least one of the upper and lower surfaces of the protruding portion and the flat portion, which can suppress an increase in temperature inside the vehicle due to sunlight passing through the protruding portion and the flat portion, and ensure excellent visibility and durability.

[0018] An industrial vehicle according to another aspect of the present invention comprises a driver's seat in which a user can sit, a loading device capable of loading cargo, and a head guard, wherein the head guard has a protruding portion that is provided directly above the driver's seat and protrudes upward, and a flat portion that is provided on the loading device side of the protruding portion and above the driver's seat, the protruding portion and the flat portion being inclined toward either the front or rear in the fore-and-aft direction connecting the loading device and the driver's seat, and at least the flat portion is transparent to visible light.

[0019] A roof member for an industrial vehicle according to another aspect of the present invention is provided directly above the driver's seat of an industrial vehicle having a loading device capable of loading cargo, and comprises a protruding portion that protrudes upward, and a flat portion that is provided on the loading device side of the protruding portion and above the driver's seat, and both the protruding portion and the flat portion are inclined toward either the front or rear in the fore-and-aft direction connecting the loading device and the driver's seat, and at least the flat portion is transparent to visible light.

[0020] According to this industrial vehicle and roof member for an industrial vehicle, it is possible to obtain the same functions and effects as the head guard for the industrial vehicle described above. [Effects of the Invention]

[0023] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Note that identical or corresponding parts in each drawing are denoted by the same reference numerals, and redundant description will be omitted. In the following description, the X-axis, Y-axis, and Z-axis directions are mutually orthogonal axes in a Cartesian coordinate system in three-dimensional space. The X-axis and Y-axis directions are, for example, horizontal directions. For example, the X-axis direction is a horizontal direction, and the Y-axis direction is a horizontal direction intersecting the X-axis direction. In this embodiment, the positive direction of the X-axis direction is referred to as "rightward," the negative direction of the X-axis direction is referred to as "leftward," and the X-axis direction is referred to as the "left-right direction." In this embodiment, the positive direction of the Y-axis direction is referred to as "forward," the negative direction of the Y-axis direction is referred to as "rearward," and the Y-axis direction is referred to as the "front-to-back direction." The left-to-right direction is an example of a direction intersecting the front-to-back direction. The Z-axis direction is, for example, the up-down direction (vertical direction). In this embodiment, the positive direction of the Z-axis direction is referred to as "upward," and the negative direction of the Z-axis direction is referred to as "downward."

[0024] Fig. 1 is a side view showing a forklift, which is an industrial vehicle equipped with a head guard according to an embodiment of the present invention. In Fig. 1, the forklift 1, which is an example of an industrial vehicle, is, for example, a counterbalance type electric forklift. The forklift 1 is an industrial vehicle used for loading and unloading.

[0025] The vehicle comprises a vehicle body 2, a pair of drive wheels 3 arranged at the front of the vehicle body 2, a pair of steering wheels 4 arranged at the rear of the vehicle body 2, and a loading device 5 arranged at the front side of the vehicle body 2. The pair of drive wheels 3 and the pair of steering wheels 4 are capable of contacting the floor surface extending horizontally and rotate. A counterweight 6 is mounted at the rear of the vehicle body 2 to balance the vehicle body 2 in the fore-and-aft direction.

[0026] The cargo handling device 5 has a mast 7 erected at the front end of the vehicle body 2, a pair of forks 9 attached to the mast 7 via lift brackets 8, a lift cylinder 10 that raises and lowers the forks 9, and a tilt cylinder 11 that tilts the mast 7. The cargo handling device 5 is an example of a cargo handling device. The forks 9 are a portion that can carry cargo L. The cargo handling device 5 can place the cargo L on a loading surface SHa of a shelf SH. The loading surface SHa is, for example, the top shelf of the shelf SH.

[0027] The forklift 1 also includes a travel motor 12, a cargo handling motor 13, and a battery pack 14. The battery pack 14 is a power supply source for the travel motor 12 and the cargo handling motor 13.

[0028] The traveling motor 12 is an AC motor that rotates the drive wheels 3. When the traveling motor 12 is driven to rotate, the driving force of the traveling motor 12 is transmitted to the drive wheels 3 via a reducer, causing the drive wheels 3 to rotate. The traveling motor 12 also functions as a generator. Specifically, when braking the forklift 1, the rotation of the drive wheels 3 causes the traveling motor 12 to operate as a generator. In other words, regenerative braking of the traveling motor 12 is performed, and regenerative power is generated from the traveling motor 12.

[0029] The cargo handling motor 13 is an AC motor that drives a hydraulic pump (not shown) that supplies hydraulic oil to the lift cylinder 10 and tilt cylinder 11. An oil control valve that switches the flow direction of the hydraulic oil is arranged between the hydraulic pump (not shown) and the lift cylinder 10 and tilt cylinder 11.

[0030] The vehicle body 2 further includes a driver's seat 17 and a head guard 20. The head guard 20 includes a pair of left and right front pillars 15 and a pair of left and right rear pillars 16. The rear pillars 16 are disposed behind the front pillars 15. The driver's seat 17 is provided horizontally between the pair of left and right front pillars 15 and the pair of left and right rear pillars 16. The driver's seat 17 is configured to allow a user U to sit (ride) in it. The driver's seat 17 has a seating surface on which the user U can sit. The size of the seating surface is, for example, a value obtained by adding a predetermined area to a statistical quantity such as the average or median of the buttock sizes of users U who ride or are estimated to ride the forklift 1. The user U seated in the driver's seat 17 can, for example, view at least one of the lower part of the cargo handling device 5 and the space below the cargo handling device 5 through the head guard 20.

[0031] In this embodiment, the front pillar 15 is inclined rearward as it approaches its upper portion. The front pillar 15 has, for example, side pillars 15a extending in the front-to-rear direction at its upper portion. The rear ends of the side pillars 15a are connected to the upper ends of the rear pillars 16. In other words, the side pillars 15a, which form at least a portion of the upper portion of the front pillars 15, are provided above the driver's seat 17. A head guard 20 is connected between the pair of left and right side pillars 15a. The head guard 20 is provided above the driver's seat 17.

[0032] FIG. 2 is a perspective view showing an example of a head guard and a roof member of an industrial vehicle according to one embodiment. FIG. 3 is another perspective view of the example of the head guard and the roof member of the industrial vehicle shown in FIG. 2, viewed from a different angle. FIG. 4 is a plan view showing an example of the head guard and the roof member of the industrial vehicle according to one embodiment. As shown in FIGS. 2 to 4, the head guard 20 includes a support member 30, a roof member 40, and a water guide section 50. Note that "water guide" in this embodiment includes guiding and flowing a liquid. "Drainage" includes removing a liquid. "Overflow" includes the overflow of a liquid. Liquid includes water such as rainwater and industrial water.

[0033] The support member 30 supports the roof member 40 from below. The support member 30 is a flat plate-shaped member. The support member 30 is inclined toward either the front or rear in the front-rear direction connecting the cargo handling device 5 and the driver's seat 17. As shown in Figures 2 and 3, the support member 30 extends along the left-right direction and an inclination direction T that is aligned with the front-rear direction and inclined downward toward the front. The inclination direction T is inclined downward with respect to the front-rear direction (horizontal direction) at an angle greater than 0 degrees and less than 10 degrees. In this embodiment, the inclination direction T intersects with the left-right direction and the up-down direction, and is inclined downward toward the front at a predetermined angle in the range of 1 degree to 3 degrees. The inclination direction T is aligned with the Y-axis in the left-right direction.

[0034] FIG. 5 is a perspective view showing an example of a support member and a bar member included in a head guard of an industrial vehicle according to one embodiment. As shown in FIG. 5, the support member 30 is a frame-shaped member having at least one opening 30a formed therethrough in the up-down direction. In the example shown in FIG. 5, the support member 30 has one rectangular opening 30a formed in its center. The opening 30a is larger than the driver's seat 17 in the front-rear and left-right directions. Therefore, in the example shown in FIG. 5, the opening 30a provided in the support member 30 is not formed in a lattice shape. In other words, the support member 30 does not have any portion that blocks the space between the roof member 40 and the user U.

[0035] The support member 30 includes a right end portion 31 and a left end portion 32 extending in the front-rear direction, and a rear end portion 33 extending in the left-right direction. A rear combination lamp (not shown) is provided behind the rear end portion 33 of the support member 30.

[0036] The head guard 20 further includes a bar member 35. The bar member 35 extends in the left-right direction across at least one opening 30a of the support member 30 and is fixed to the support member 30. The bar member 35 extends in the left-right direction and has a rectangular parallelepiped shape. The bar member 35 is fixed to the underside of the right end portion 31 and the underside of the left end portion 32 of the support member 30 by welding or the like. The bar member 35 is provided, for example, directly below a protrusion 41 described below. The bar member 35 is provided, for example, directly below a front end portion 45 of the protrusion 41 described below. In other words, the bar member 35 is disposed spaced apart from the roof member 40. When an impact is applied to the roof member 40, such as when an object falls on it, causing the roof member 40 to bend downward, the bar member 35 abuts against the bent roof member 40, thereby suppressing the downward bending of the roof member 40. The bar member 35 may be molded integrally with the support member 30 as the same member.

[0037] The support member 30 has a plurality of female thread portions 30b used for connecting to a pair of second water guide portions 54 and third water guide portions 55, which will be described later. In the example shown in Fig. 5, the support member 30 has two female thread portions 30b formed at the right end portion 31, two female thread portions 30b formed at the left end portion 32, and four female thread portions 30b formed at the front portion of the rear end portion 33.

[0038] The roof member 40 shown in Figures 2 to 4 covers the area above the driver's seat 17. The roof member 40 covers the entire opening 30a of the support member 30 from above. This prevents the driver's seat 17 from getting wet due to water falling from above. The roof member 40 is, for example, a thin plate. The roof member 40 is made of, for example, resin. The roof member 40 is molded as a single piece. The roof member 40 is inclined toward either the front or rear in the front-to-rear direction connecting the cargo handling device 5 and the driver's seat 17. Since the roof member 40 is provided on the support member 30, the roof member 40 extends along the inclination direction T and the left-to-right direction. The support member 30 extends further to the right and left than the roof member 40. The roof member 40 is fixed to the support member 30 by fixing parts 56, which will be described later. The roof member 40 covers the opening 30a of the support member 30 and is supported by having its outer edge fixed to the support member 30. The outer edge of the roof member 40 is formed with a plurality of openings through which, for example, male screws of the fixing portion 56 (described later) can be inserted.

[0039] The configuration of the roof member 40 will be described in detail. A coating layer is provided on at least one of the upper and lower surfaces of the roof member 40. That is, a coating layer is provided on at least one of the upper and lower surfaces of each of the protruding portion 41 and the flat portion 48 described below. The coating layer protects the substrate on which the coating layer is formed. FIG. 6 is a cross-sectional view showing an example of a roof member included in a head guard for an industrial vehicle according to one embodiment. In the example shown in FIG. 6, the roof member 40 has a substrate 401, a first coating layer 403, and a second coating layer 405.

[0040] The substrate 401 is made of transparent resin and has an outer surface 401a facing upward (outside the vehicle) and an inner surface 401b facing downward (inside the vehicle). The substrate 401 is made of colorless, transparent polycarbonate. The substrate 401 is formed based on the shape and size of the opening 30a of the support member 30, and has a thickness of about 5 mm to 8 mm.

[0041] The first coating layer 403 is integrally formed on the outer surface 401a of the substrate 401. As a result, the first coating layer 403 faces the space above. The first coating layer 403 is formed of a colorless and transparent resin. More specifically, the first coating layer 403 has a two-layer structure consisting of a primer layer 403a made of a colorless and transparent acrylic resin and a surface layer 403b made of a colorless and transparent silicone resin. The primer layer 403a is formed on the outer surface 401a of the substrate 401 and is in contact with the outer surface 401a. The surface layer 403b is formed on the primer layer 403a and is in contact with the space above. The surface layer 403b is formed to be smooth. As a result, the first coating layer 403 is smooth. The primer layer 403a may be formed of a resin other than an acrylic resin, and the surface layer 403b may be formed of a resin other than a silicone resin. The first coating layer 403 may also have a single-layer structure.

[0042] The second coating layer 405 is integrally formed on the inner surface 401b of the substrate 401. As a result, the second coating layer 405 faces the space below. The second coating layer 405 is mainly composed of a colorless and transparent acrylic resin. Unlike the first coating layer 403, the second coating layer 405 has a single-layer structure. Note that the second coating layer 405 may be formed of a resin other than an acrylic resin. The second coating layer 405 contains a plurality of reflective particles 407 that reflect sunlight (infrared rays, visible light, and ultraviolet rays). The plurality of reflective particles 407 are embedded in the second coating layer 405. Note that the second coating layer 405 may also have a function of absorbing sunlight. Note that in FIG. 6, for ease of explanation, the thicknesses of the substrate 401, the first coating layer 403, and the second coating layer 405, as well as the particle size of the reflective particles 407, are exaggerated.

[0043] The roof member 40 shown in FIGS. 2 to 4 has a protruding portion 41 and a flat plate portion 48. The roof member 40 further has an extending portion 70. In this embodiment, the protruding portion 41, the flat plate portion 48, and the extending portion 70 each represent a portion of the roof member 40. That is, the roof member 40 including the protruding portion 41, the flat plate portion 48, and the extending portion 70 is integrally molded. In the roof member 40, at least the flat plate portion 48 is visible light transmissive. In this embodiment, the protruding portion 41 and the extending portion 70 are visible light transmissive, for example, similar to the flat plate portion 48. That is, a user U seated in the driver's seat 17 can view the space above through the protruding portion 41, the flat plate portion 48, and the extending portion 70. The protruding portion 41, the flat plate portion 48, and the extending portion 70 are all inclined toward either the front or the rear in the front-to-rear direction. That is, the protruding portion 41, the flat plate portion 48, and the extending portion 70 are inclined in the same direction. In this embodiment, the protruding portion 41, the flat plate portion 48, and the extending portion 70 extend in the inclined direction T and the left-right direction. In the front-rear direction, the length of the protruding portion 41 is longer than the length of the flat plate portion 48.

[0044] The protruding portion 41 is provided directly above the driver's seat 17 and protrudes upward. Fig. 7 is a cross-sectional view showing an example of a head guard and roof member for an industrial vehicle taken along line VII-VII shown in Fig. 4. That is, Fig. 7 is a front view of the cross section of the head guard 20 of the forklift 1. As shown in Fig. 7, the protruding portion 41 has a right end portion 42, a left end portion 43, and a central portion 44 located between the right end portion 42 and the left end portion 43 in the left-right direction.

[0045] The protruding portion 41 has a central portion 44 that protrudes upward in the left-right direction. The central portion 44 has the portion that protrudes the most in the left-right direction. The protruding portion 41 is, for example, a curved portion. The central portion 44 is located higher than the right end portion 42 and the left end portion 43. The protruding portion 41 has a rounded curved surface. The right end portion 42 and the left end portion 43 may, for example, be portions that protrude upward to a greater extent than the central portion 44. A greater degree of protrusion refers, for example, to a greater curvature. The right end portion 42 and the central portion 44 are connected by a smoothly curved portion. The smoothly curved portion refers to a portion that is not uneven enough to allow water to accumulate. The left end portion 43 and the central portion 44 are connected by a smoothly curved portion. The central portion 44 may, for example, be a flat portion extending in the inclination direction T and the left-right direction. The protruding portion 41 can accommodate, for example, the head of a user seated (riding) on ​​the driver's seat 17 directly below the central portion 44 thereof.

[0046] FIG. 8 is a cross-sectional view showing an example of a head guard and a roof member of an industrial vehicle taken along line VIII-VIII shown in FIG. 4. FIG. 8 is a view showing a cross section of the head guard 20 of the forklift 1 viewed from left to right. As shown in FIG. 8, the protruding portion 41 has a front end portion 45, a rear end portion 46, and a central portion 47 located between the front end portion 45 and the rear end portion 46 in the front-to-rear direction. In this embodiment, the position of the central portion 47 in the front-to-rear direction coincides with the position of the central portion 47 in the left-to-right direction. The front end portion 45 may be a portion that slopes downward as it moves forward relative to the inclination direction T. The rear end portion 46 may be a portion that slopes downward as it moves forward, for example.

[0047] The rear end 46 may have a portion that does not extend along the inclination direction T. In this case, the portion may not extend along the front-to-rear direction. The portion may be inclined downward at least as it moves forward, or may be inclined upward at least as it moves forward. When the portion of the rear end 46 that does not extend along the inclination direction T extends along the front-to-rear direction, the portion may have a structure that inclines downward as it moves left and right from the center in the left-to-right direction. This allows liquid present in the portion to be properly discharged.

[0048] The protruding portion 41 has a central portion 47 that protrudes upward in the front-to-rear direction. The central portion 44 is located higher than the front end portion 45 and the rear end portion 46. The front end portion 45 and the rear end portion 46 may, for example, be portions that protrude upward to a greater extent than the central portion 47. The front end portion 45 and the central portion 47 in the front-to-rear direction are connected by a smoothly curved portion. The rear end portion 46 and the central portion 47 are connected by a smoothly curved portion. The central portion 47 may, for example, be a flat portion extending in the inclination direction T and the front-to-rear direction. The protruding portion 41 can accommodate the head of a user seated (riding) on ​​the driver's seat 17, for example, directly below the central portion 47.

[0049] As shown in Figures 2 to 4, the flat plate portion 48 is provided above the driver's seat 17. The flat plate portion 48 is provided closer to the cargo handling device 5 than the protruding portion 41, i.e., further forward. In this embodiment, the rear end of the flat plate portion 48 is connected to, for example, the front end portion 45 of the protruding portion 41. The flat plate portion 48 extends further in the left-right direction than the driver's seat 17. The flat plate portion 48 extends along the tilt direction T and the left-right direction, and its upper surface is a smooth surface.

[0050] Here, the loading device 5 loads the cargo L onto a shelf SH or the like capable of loading the cargo L, or receives the cargo L from the shelf SH. For this reason, as shown in FIG. 1 , the user U needs to recognize the tip of the fork 9 and the bottom end of the cargo L moved to the upper end by the loading device 5 from the user U's viewpoint VP (the position of the user U's eyes). The user U also needs to recognize the end of the loading surface SHa of the shelf SH to which the cargo L is to be transferred from the viewpoint VP. The viewpoint VP of the user U is, for example, a statistical quantity such as the average or median of the eye positions of the user U who is riding or is estimated to be riding the forklift 1. Here, the range VF1 visible from the user U's viewpoint VP through the flat plate portion 48 can ensure a range VF2 above the roof member 40 (for example, a space including the periphery of the cargo L and the loading device 5). A part of the flat plate portion 48 is provided at a position intersecting a line connecting the position of the lower end of the cargo handling device 5 or the cargo L that can be loaded onto the cargo handling device and the estimated position of the viewpoint VP of the user U that can ride in the driver's seat 17. In this embodiment, the range VF1 is set so that the lower end of the cargo handling device 5 and the lower end of the cargo L that is moved upward by the cargo handling device 5 and estimated to be loaded by the cargo handling device 5 fall within the range VF2. The flat plate portion 48 in this embodiment extends at least longer in the front-rear direction than the set range VF1.

[0051] Referring again to FIGS. 2 to 4, the extending portion 70 is connected to the protruding portion 41 and the flat plate portion 48 and is provided on at least one of both ends of the protruding portion 41 in the left-right direction. In the example shown in FIGS. 2 to 4, the extending portion 70 has a first extending portion 71 provided on the right side of the right end portion 42 of the protruding portion 41 and a second extending portion 72 provided on the left side of the left end portion 43 of the protruding portion 41. That is, the extending portion 70 has a pair of portions and is arranged to sandwich the protruding portion 41 therebetween in the left-right direction. The first extending portion 71 and the second extending portion 72 are inclined together with the protruding portion 41 and the flat plate portion 48 and extend in a flat plate shape along the flat plate portion 48. The first extending portion 71 and the second extending portion 72 extend along the inclination direction T and the left-right direction. The first extending portion 71 and the second extending portion 72 are arranged to be flush with the flat plate portion 48. The first extension portion 71 and the second extension portion 72 may be disposed above the flat plate portion 48. The first extension portion 71 and the second extension portion 72 are provided with two openings (not shown) aligned in the front-to-rear direction. The openings penetrate in the up-down direction, and male screws of the fixing portion 56, which will be described later, can be inserted through the openings. The openings may be threaded.

[0052] The extending portion 70 may further include a third extending portion 73 connected to the protruding portion 41, the first extending portion 71, and the second extending portion 72, and provided rearward of the rear end portion 46 of the protruding portion 41. When the inclination direction T slopes downward toward the rear and the flat portion 48 is provided rearward, the third extending portion 73 may be provided forward of the front end portion 45 of the protruding portion 41. That is, the extending portion 70 is a U-shaped portion and is arranged to surround the protruding portion 41 in the left-right direction. The third extending portion 73 slopes together with the protruding portion 41 and the flat portion 48 and extends in a flat plate shape along the first extending portion 71 and the second extending portion 72. The third extending portion 73 extends along the inclination direction T and the left-right direction. The third extending portion 73 is arranged to be flush with the first extending portion 71 and the second extending portion 72. The third extension portion 73 may be disposed above the first extension portion 71 and the second extension portion 72. The third extension portion 73 has four openings (not shown) arranged in the left-right direction. The openings penetrate in the up-down direction, and male screws of the fixing portion 56, which will be described later, can be inserted through the openings. The openings may be threaded.

[0053] The water guide section 50 includes a first water guide section 51, at least one second water guide section 54, a third water guide section 55, a fixing section 56, and a pair of side plates 58. The first water guide section 51 has the function of guiding liquid flowing forward toward the pair of front pillars 15. The first water guide section 51 is disposed in front of the roof member 40. The first water guide section 51 is provided at the front end of the support member 30. The first water guide section 51 extends in the left-right direction. The first water guide section 51 extends outward (to the left and right) from a pair of second water guide sections 54, which will be described later. The first water guide section 51 is connected to the pair of side plates 58.

[0054] The first water guide section 51 has a recess 52 (see FIG. 2) and a water channel section 53 (see FIG. 4). The recess 52 is recessed forward and extends in the left-right direction. The interior of the recess 52 is, for example, inclined downward toward the rear. The recess 52 is recessed, for example, so as to be inclined upward toward the front. That is, the first water guide section 51 is a section in which a groove (recess) is formed that extends to cover a part of the upper part. The upper surface of the section forming the recess 52 is inclined downward toward the rear. The water channel section 53 is located behind the recess 52. The water channel section 53 extends in the left-right direction. Although not shown in the figure, the center of the water channel section 53 protrudes most upward in the left-right direction, and is inclined downward from the center to the right and from the center to the left.

[0055] At least one second water guide portion 54 has the function of pressing against the roof member 40 from above and the function of guiding liquid that has flowed down the roof member 40 toward the pair of side pillars 15a toward the front. In this embodiment, the water guide portion 50 has a pair of second water guide portions 54 as the at least one second water guide portion 54. The pair of second water guide portions 54 are provided on the first extending portion 71 and the second extending portion 72 of the roof member 40, respectively. The pair of second water guide portions 54 extend in the front-rear direction at the right end of the first extending portion 71 and the flat plate portion 48, and at the left end of the second water guide portion 54 and the flat plate portion 48, and are portions that can guide water in the front-rear direction. Each second water guide portion 54 has at least one insertion portion 54a through which the fixing portion 56 is inserted.

[0056] Each second water guide section 54 is, for example, an L-shaped metal member. The second water guide section 54 has an insertion section 54a and a first section in the form of a substantially rectangular plate extending in the tilt direction T and the left-right direction, and a second section in the form of a substantially rectangular plate extending in the tilt direction T and the up-down direction. The first section is provided on the inner side (toward the central section 44) of the second section. The first section of the second water guide section 54 may extend so as to be connected to a first section of a third water guide section 55 described below. In other words, the second water guide section 54 and the third water guide section 55 may be provided so as to surround the upper surfaces of the first extending section 71, the second extending section 72, and the third extending section 73 of the roof member 40.

[0057] In the example shown in Figures 2 to 4, each second water guide section 54 is provided with two insertion sections 54a aligned in the front-to-rear direction. Each insertion section 54a curves and protrudes inward (towards the central section 44). Each insertion section 54a has a surface against which a washer of the fixing section 56, which will be described later, can come into contact. Each insertion section 54a has an opening (not shown) that penetrates in the vertical direction. The opening may be threaded.

[0058] The third water guide portion 55 has the function of pressing the roof member 40 from above and the function of preventing (blocking) liquid from flowing backward (toward the rear combination lamp). The third water guide portion 55 is provided on the third extending portion 73 of the roof member 40. The third water guide portion 55 extends in the left-right direction. The third water guide portion 55 is, for example, an L-shaped metal member. The third water guide portion 55 has a first portion having a substantially rectangular plate shape extending in the tilt direction T and the left-right direction, and a second portion having a substantially rectangular plate shape extending in the left-right direction and the up-down direction. The first portion is provided more inward (toward the central portion 44) than the second portion. The third water guide portion 55 penetrates in the up-down direction and has an opening (not shown) through which the fixing portion 56 can be inserted. The opening may be threaded. The third water guide portion 55 has a surface against which a washer of the fixing portion 56, described below, can abut.

[0059] The fixing portions 56 are used to fix the pair of second water guide portions 54 to the roof member 40 and the support member 30, and to fix the third water guide portion 55 to the roof member 40 and the support member 30. For example, the fixing portions 56 include a plurality of male screws and a plurality of washers. The male screws are, for example, bolts having a threaded insertion portion and a head portion with a larger diameter than the threaded insertion portion. The washers are located between the head of the male screws and the pair of second water guide portions 54 and third water guide portions 55. Each male screw is inserted from top to bottom through the washers, openings formed in the multiple objects to be fixed (the pair of second water guide portions 54 and third water guide portions 55), openings formed in the roof member 40, and female thread portions 30b (see FIG. 5) formed in the support member 30, in that order, and threadedly engages with the female thread portions 30b. One of the second water guide sections 54 is provided on the upper surface of the first extending section 71, above the right end 31 (see FIG. 5) of the support member 30. The other second water guide section 54 is provided on the upper surface of the second extending section 72, above the left end 32 (see FIG. 5) of the support member 30. The third water guide section 55 is provided on the upper surface of the third extending section 73, above the rear end 33 (see FIG. 5) of the support member 30. Because the pair of second water guide sections 54 and third water guide sections 55 approach the support member 30 due to the screw engagement of the fixing sections 56, the roof member 40 is sandwiched between the pair of second water guide sections 54 and third water guide sections 55 and the support member 30, and is fixed to the support member 30.

[0060] The pair of side plates 58 are provided at both ends of at least one of the protruding portion 41 and the flat plate portion 48 in the left-right direction, extend in the front-rear direction, and are capable of guiding water in the front-rear direction. As shown in FIGS. 3 to 5 , the pair of side plates 58 are provided to the right of the right end portions of the support member 30 and the roof member 40, and to the left of the left end portions of the support member 30 and the roof member 40, respectively. The pair of side plates 58 are fixed, for example, to the side surface facing right and the side surface facing left, respectively, of the support member 30. The pair of side plates 58 are provided at positions sandwiched between the side pillars 15a of the pair of front pillars 15. In other words, the roof member 40 and the pair of second water guiding portions 54 are provided at positions sandwiched between the pair of side plates 58.

[0061] Each side plate 58 extends along the inclination direction T and the up-down direction. Each side plate 58 has a generally rectangular plate shape. In the inclination direction T, each side plate 58 extends longer than the length connecting the first water guide portion 51 and the third water guide portion 55. Each side plate 58 extends at least from the side of the first water guide portion 51 to the side of the third water guide portion 55. Each side plate 58 may extend to the rear end of the rear pillar 16, for example.

[0062] Each side plate 58 extends above the support member 30. As a result, when liquid flows down to the right or left from the roof member 40, the liquid flows down over the support member 30, but each side plate 58 can prevent the liquid from flowing down toward the side pillar 15a. Therefore, the liquid that flows down to the right or left from the roof member 40 flows down along each side plate 58 in the inclined direction T.

[0063] The water guide portion 50 is formed with a drain outlet that can drain water from at least one end in the left-right direction. In the example shown in FIG. 4, each side plate 58 is formed with a drain outlet 59 that penetrates in the left-right direction at its front end. The drain outlet 59 may be a notch that also opens upward. Although not shown in the figure, the drain outlet 59 opens, for example, to the same height as the right and left ends of the water channel portion 53. As a result, liquid flowing down along the water channel portion 53 and each side plate 58 is discharged through the drain outlet 59 toward the front pillar 15.

[0064] For example, a pipe 60 (see FIG. 4) and a hose (not shown) through which liquid can flow are provided on the front pillar 15. The opening at the upper end of the pipe is provided directly below the drain outlet 59. The hose is connected to the lower end of the pipe. Liquid discharged from the drain outlet 59 is guided toward the pipe. Liquid flowing down inside the pipe is guided from the pipe to the hose and discharged below the head guard 20.

[0065] Here, how liquid that falls on roof member 40 flows down will be described in detail with reference to Figure 4. Protruding portion 41 is curved upward in the left-right and front-rear directions and is inclined in inclination direction T, so liquid that falls on central portions 44, 47 of protruding portion 41 flows down to the right and in inclination direction T, or to the left and in inclination direction T, as shown by arrow F1.

[0066] Furthermore, a pair of second water guide sections 54 are provided at both left and right ends of roof member 40, preventing liquid from flowing down to the right at the right end and to the left at the left end. As a result, liquid that reaches right end 42 and left end 43 of protrusion 41 flows down along second water guide sections 54 in the tilt direction T, as shown by arrow F2.

[0067] Since the flat plate portion 48 of the roof member 40 is inclined in the inclination direction T, the liquid that reaches the flat plate portion 48 flows down along the inclination direction T toward the first water guide portion 51, as shown by arrow F3.

[0068] If a large amount of liquid falls on the roof member 40, the liquid may overflow from each second water guide section 54. Furthermore, depending on the acceleration of the forklift 1, the liquid that falls on the rear end of the roof member 40 may flow down from the area of ​​the roof member 40 between each second water guide section 54 and the third water guide section 55 onto the support member 30. In these cases, the liquid moves to the upper surface of the support member 30 between the second water guide section 54 located at the right end of the head guard 20 and the side plate 58, and to the upper surface of the support member 30 between the second water guide section 54 located at the left end of the head guard 20 and the side plate 58. Because the support member 30 is inclined in the inclination direction T, the liquid that reaches the upper surface of the support member 30 flows down in the inclination direction T as shown by arrow F4.

[0069] Because the first water conduit section 51 is inclined downward from its center to the right and left, liquid that reaches the water channel section 53 of the first water conduit section 51 flows down to the right and left, as shown by arrow F5, toward each side plate 58. The recessed section 52 of the first water conduit section 51 and the upper surface that constitutes the recessed section 52 are inclined downward toward the rear, so that liquid flowing down the roof member 40 in the inclination direction T can be received. The recessed section 52 is inclined downward toward the rear, so that the possibility of liquid overflowing from the first water conduit section 51 can be reduced even if the amount of liquid flowing down in the inclination direction T is large.

[0070] The liquid that flows down along arrow F4 and the liquid that flows down along arrow F5 flows out from drain outlets 59 provided in each side plate 58 toward the side pillar 15a as shown by arrow F6. The liquid that flows out from drain outlets 59 flows downward along pipes 60 provided in the front pillar 15 as shown by arrow F7. The liquid that flows down pipe 60 is guided from pipe 60 to a hose (not shown) and is discharged below the head guard 20. In this way, liquid that falls on the roof member 40 is prevented from accumulating on the roof member 40 and is properly drained from the roof member 40.

[0071] Next, we will explain the effects of the forklift 1 and head guard 20 of this embodiment, while explaining the problems with conventional forklifts (industrial vehicles). Forklifts may be used or stored in environments where liquid may pour onto the head guard from above the forklift, such as outdoors where it is subject to rain. In such cases, the head guards used in conventional forklifts extend horizontally, which can cause liquid to accumulate on the head guard. If the forklift is moved while liquid has accumulated on it, the liquid may pour onto the user riding the forklift, potentially reducing operability and comfort. Furthermore, liquid accumulated on the transparent head guard acts as a lens, concentrating sunlight that passes through the liquid and the head guard, potentially causing parts of the forklift to become hot. Therefore, there has been a need for a head guard for an industrial vehicle that is designed to prevent liquid from accumulating and that can adequately ensure visibility above (the space above), as well as an industrial vehicle equipped with such a head guard.

[0072] In the forklift 1 (an example of an industrial vehicle), head guard 20, and roof member 40 of this embodiment, the protruding portion 41 and the flat plate portion 48 are both inclined toward either the front or rear direction, so that liquid that falls on the head guard 20 is guided in the inclined direction T. This makes it difficult for liquid to accumulate on the protruding portion 41 and the flat plate portion 48. Therefore, even when moving the forklift 1, the possibility of the liquid spilling on the user U riding the forklift 1 is reduced, ensuring appropriate operability and comfort. Furthermore, sunlight that passes through the liquid and the head guard 20 is concentrated, preventing parts of the forklift 1 from becoming too hot. Furthermore, the user U can view the upper area through the flat plate portion 48, which is less likely to accumulate liquid. Furthermore, the protruding portion 41 is provided directly above the driver's seat 17, improving the comfort of the user U seated in the driver's seat 17. Furthermore, by locating the flat plate portion closer to the loading device than the protruding portion, for example, the flat plate portion can be located between the user's viewpoint and the loading device that has moved upward, thereby ensuring appropriate visibility above. Furthermore, if the roof member 40 slopes downward toward the front, the protruding portion 41 located behind the flat plate portion 48 allows even small amounts of liquid to easily flow down due to the steep slope at the rear of the forklift 1. Furthermore, as described above, the liquid on the flat plate portion 48 can more easily flow down by combining with the liquid flowing down from the protruding portion 41. Therefore, the forklift 1 and head guard 20 have a structure that makes it difficult for liquid to accumulate, thereby ensuring appropriate visibility above. Furthermore, if the protruding portion on the roof member is located at a position that intersects with a line connecting the user U's visual target and the estimated position of the user U's viewpoint VP, who may be seated in the driver's seat 17, distortion of the user U's field of view may occur. This is particularly likely to occur if at least a portion of the protruding portion is formed of a curved surface. However, the user U in the driver's seat 17 can view through the flat plate portion 48, ensuring a less distorted field of view, while ensuring comfort for the user through the protrusion 41. In other words, the head guard 20 and roof member 40 of this embodiment can achieve both improved visibility and ensure comfort.For example, since the flat plate portion 48 extends farther than the driver's seat 17 in the left-right direction, a wide area of ​​the space above the head guard can be seen.

[0073] Furthermore, in the front-rear direction, the length of the protruding portion 41 is longer than the length of the flat plate portion 48. In this case, the protruding portion 41 is provided directly above the driver's seat 17, is long in the front-rear direction, and a large space is secured above it, so that the comfort of the user U seated in the driver's seat 17 can be more appropriately secured.

[0074] Furthermore, a portion of the flat plate portion 48 may be provided at a position that intersects with a straight line connecting the position of the lower end of the cargo handling device 5 or the cargo L that can be loaded on the cargo handling device 5 and the estimated position of the viewpoint VP of the user U who can sit in the driver's seat 17. In this case, the user U sitting in the driver's seat 17 can visually confirm the position of the lower end of the cargo handling device 5 and the position of the lower end of the cargo L loaded on the cargo handling device 5 via the flat plate portion 48. Therefore, it is possible to appropriately ensure visibility of the space above the driver's seat 17, such as the cargo handling device 5, the cargo L that can be loaded on the cargo handling device 5, and the space below the cargo L (for example, the placement surface SHa of the shelf SH).

[0075] Furthermore, the central portion 44 of the protruding portion 41 may protrude upward in the left-right direction intersecting the front-rear direction. In this case, for example, the amount of liquid that falls on the protruding portion 41 and flows onto the flat plate portion 48 can be reduced, resulting in a structure that makes it difficult for liquid to accumulate and ensuring appropriate visibility of the upper portion.

[0076] The head guard 20 may further include a first water guide portion 51 (water guide portion 50) that is provided at the lower end of the protruding portion 41 and the flat plate portion 48 in the inclination direction T, extends in a left-right direction intersecting the front-rear direction, and is capable of guiding water in the left-right direction, and the pair of side plates 58 (water guide portions 50) may be formed with drainage ports 59 that can drain from at least one end in the left-right direction. In this case, the head guard 20 can drain liquid that has flowed from the protruding portion 41 and the flat plate portion 48 through the drainage ports 59 formed in at least one of the left and right directions. This reduces the possibility of liquid dripping at the center portion 44 of the head guard 20 in the left-right direction, and appropriately ensures the visibility and comfort of the user U.

[0077] The head guard 20 and the roof member 40 may further include an extending portion 70 (first extending portion 71 and second extending portion 72) connected to the protruding portion 41 and the flat plate portion 48, provided at at least one of both ends of the protruding portion 41 in the left-right direction intersecting the front-to-rear direction, and inclined together with the protruding portion 41 and the flat plate portion 48 toward either the front or rear in the front-to-rear direction and extending in a flat plate shape along the flat plate portion 48; and a water guide portion 50 (second water guide portion 54) extending in the front-to-rear direction on the extending portion 70 and the flat plate portion 48 and capable of guided water in the front-to-rear direction. In this case, the inclination of the extending portion 70 allows liquid on the extending portion 70 to be drained in the front-to-rear direction. The water guide portion 50 (second water guide portion 54) can receive liquid flowing in the left-to-right direction from the protruding portion 41 via the extending portion 70 and liquid flowing in the left-to-right direction from the flat plate portion 48, and guide the water in the front-to-rear direction. This reduces the possibility of liquid dripping on at least one of the left and right ends of the head guard 20, thereby ensuring appropriate visibility and comfort for the user U. Furthermore, the second water guide section 54 is attached to the support member 30 with the roof member 40 sandwiched between them. Because the extension section 70 extends in a flat plate shape, it becomes easier to attach the second water guide section 54 to the roof member 40 and the support member 30. In particular, when the support member 30 is a metal member such as iron, the portion where the fixing section 56 is fixed (fastened) to the roof member 40 and the surrounding area of ​​this portion are flat, making it easy to fix the second water guide section 54 using the fixing section 56.

[0078] The extension portion 70 may further include a third extension portion 73 connected to the protrusion 41, the first extension portion 71, and the second extension portion 72 and provided rearward of the rear end portion 46 of the protrusion 41. In this case, the extension portion 70 is also inclined rearward of the protrusion 41, allowing liquid on the extension portion 70 to be drained in the front-to-rear direction. Even if liquid flows rearward from the third extension portion 73 in the opposite direction to the inclination direction T, the water guide portion 50 (third water guide portion 55) can prevent (block) the liquid from flowing rearward (toward the rear combination lamp). This reduces the possibility of liquid dripping behind the head guard 20, thereby ensuring appropriate visibility and comfort for the user U. The third water guide portion 55 is attached to the support member 30, sandwiching the roof member 40 therebetween. The extension portion 70 extends in a flat plate shape, which makes it easier to attach the third water guide portion 55 to the roof member 40 and the support member 30. In particular, when the support member 30 is a metal member such as iron, the portion where the fixing portion 56 is fixed (fastened) to the roof member 40 and the surrounding area of ​​this portion are flat, which makes it easier to fix the third water guide portion 55 using the fixing portion 56.

[0079] The head guard 20 may further include a flat support member 30 that supports the protruding portion 41 and the flat portion 48 from below, and the protruding portion 41 and the flat portion 48 may be attached to the support member 30. In this case, the protruding portion 41 and the flat portion 48 are attached to the flat support member 30 from below, which prevents unevenness in the structure supporting the protruding portion 41 and the flat portion 48 from affecting the protruding portion 41 and the flat portion 48. This prevents liquid from accumulating in parts of the protruding portion 41 and the flat portion 48, and improves the attachability and sealing properties of the protruding portion 41 and the flat portion 48.

[0080] Furthermore, the protruding portion 41 and the flat portion 48 each constitute a part of the roof member 40 integrally molded from resin. The support member 30 is a frame-shaped member having a single opening 30a formed therethrough in the up-down direction, and the roof member 40 may be supported by covering the opening 30a of the support member 30 and having its outer edge fixed to the support member 30. In this case, the protruding portion 41 and the flat portion 48 cover the single large opening 30a formed in the frame-shaped support member 30. That is, the single opening 30a is covered by the roof member 40. This prevents the support member 30 from narrowing the upward field of view of the user U seated in the driver's seat 17. Furthermore, for example, the roof member 40 is made of resin (polycarbonate), and is therefore lightweight. Therefore, the frame-shaped support member 30 can support a roof member 40 having a large area. Furthermore, the support member 30 may have a single opening 30a that is larger than the driver's seat 17 in the front-rear and left-right directions. In this case, since the roof member 40 is made of resin, the frame-shaped support member 30 can support the protruding portion 41 and the flat plate portion 48, and a wide field of view for the user U can be ensured.

[0081] Furthermore, the head guard 20 may further include a bar member 35 that extends across at least one opening 30a of the support member 30 in the left-right direction that intersects with the front-rear direction and is fixed to the support member 30. In this case, even if an impact is applied to the protruding portion 41 and the flat plate portion 48 by an object falling from above, etc., the deflection of the protruding portion 41 and the flat plate portion 48 can be kept small.

[0082] Furthermore, a coating layer (first coating layer 403 and second coating layer 405) may be provided on at least one of the upper and lower surfaces of each of the protruding portion 41 and the flat plate portion 48. The first coating layer 403 and the second coating layer 405 are made of, for example, a transparent resin, and can reinforce the resin roof member 40 and prevent deterioration of the substrate 401 of the roof member 40 due to ultraviolet rays. Furthermore, the second coating layer 405 of this embodiment contains reflective particles 407 that reflect sunlight (infrared rays, visible light, and ultraviolet rays), thereby further improving the light concentration suppression effect. In this way, it is possible to suppress a temperature rise inside the forklift 1 due to sunlight passing through the protruding portion 41 and the flat plate portion 48, and ensure excellent visibility and durability of the roof member 40.

[0083] Although various exemplary embodiments have been described above, the present disclosure is not limited to the above-described exemplary embodiments, and various omissions, substitutions, and modifications may be made. For example, the support member 30 may have a plurality of openings 30a formed therein. The support member 30 and the roof member 40 may extend so as to slope downward toward the rear. The protruding portion 41 may slope downward toward either the right or left. In other words, the central portion 44 may not protrude the most upward. The protruding portion 41 may slope downward toward either the front or rear. In other words, the central portion 47 may not protrude the most upward.

[0084] The roof member 40 does not necessarily have to have the extension 70. In this case, the head guard 20 may further include a second water guide portion 54 (another water guide portion 50) that is provided on at least one of both ends of the protruding portion 41 and the flat plate portion 48 in the left-right direction, extends in the front-rear direction, and is capable of guiding water in the front-rear direction. In this case, the pair of second water guide portions 54 may be attached to, for example, the right end 42 and the left end 43 of the protruding portion 41. The second water guide portion 54 can receive liquid flowing in the left-right direction from the protruding portion 41 and the flat plate portion 48 and guide the water in the front-rear direction. This reduces the possibility of liquid dripping at both ends of the head guard 20 in the left-right direction, thereby ensuring the visibility and comfort of the user U. Furthermore, the third water guide portion 55 may be attached to, for example, the rear end 46 of the protruding portion 41.

[0085] The second water guide portion 54 and the third water guide portion 55 may be configured, for example, from the same member. The flat plate portion 48 may be provided on at least one of the right, left, and rear of the protruding portion 41.
