  The windshield 10 shown in FIGS. 5 and 6 is for protecting the driver from the traveling wind, and includes a windshield main body 21, an air guide cover 22, and positioning mechanisms 23L and 23R (see FIG. 8 and the like described later). And a cover member 24. The windshield body 21 is disposed on the front side of the vehicle body 2 so as to be positioned in front of the driver for wind protection. The windshield main body 21 is made of a colorless and transparent synthetic resin and is formed symmetrically. More specifically, the windshield main body 21 is formed in a substantially pentagonal shape that is curved so that a central portion in the left-right direction protrudes forward with respect to the left and right sides, and has a tapered lower end in front view. Mounted portions 15e and 15f of the movable body 15 are arranged along the back surface at intervals in the left-right direction on the back surface (that is, the rear surface) of the windshield main body 21, and each mounted portion 15e, 15f is fastened to the windshield body 21 by three fastening members 17a to 17c. Therefore, the windshield main body 21 moves to the upper position and the lower position by raising and lowering the movable body 15 (see also the solid line and the two-dot chain line in FIG. 11). The upper end of the windshield body 21 is located near or above the top of the driver when viewed from the front when positioned at the highest upper position, and near the driver's mouth when positioned at the lowest lower position. Located below the mouth. In the windshield body 21 thus formed, the air inlet 31 is formed so as to be positioned between the attached portions 15e and 15f in a front view.

  The air guide port 31 has a substantially trapezoidal shape that is long in the left-right direction, the upper edge portion of the air guide port 31 is formed substantially linearly in the left-right direction in plan view, and the lower edge portion of the air guide port 31 is It is formed in a V shape in plan view. The air guide 31 having such a shape is an opening for taking in the traveling wind and guiding it around the chest of the driver, and is an area below the center in the vertical direction in the windshield body 21, that is, a lower area. Is formed. Therefore, when the windshield main body 21 is located at the upper position, all the air guide holes 31 are located above the meter visor 4 in front view. On the other hand, when the windshield main body 21 is located at the lower position, as shown in FIG. 7, all of the air ducts 31 are located so as to overlap the meter visor 4 in front view. The air guide port 31 is arranged in this way, and guides the air taken in when the windshield body 21 is in the upper position to the vicinity of the driver's chest without being blocked by the meter visor 4. Further, when the windshield main body 21 is positioned at the lower position, the air taken in by the air guide port 31 can be blocked by the meter visor 4 so as not to hit the driver. In addition, the windshield 10 is provided with mounting plates 32 on both the left and right sides of the air inlet 31.

  Each of the mounting plates 32 has a fixed portion 32a and a mounting portion 32b as shown in FIGS. The fixing portion 32a of the mounting plate 32, which is a mounting member, is disposed along the surface (ie, the front surface) of the windshield body 21, and as shown in FIG. 10, the two fastening members 17a and 17b together with the windshield body 21. Are attached to the attached portions 15e and 15f together (see also FIG. 4). By fastening together, it is not necessary to form another hole in the windshield main body 21 in order to attach the mounting plate 32, and a decrease in strength of the windshield main body 21 can be suppressed. Further, by attaching the fixed portion 32a to the attached portions 15e and 15f, it is possible to prevent the windshield body 21 from being damaged due to a large force acting on the fixed portion 32a.

  Further, as shown in FIGS. 8 to 10, in the mounting plate 32, the mounting portion 32b is integrally formed at the side end portion of the fixed portion 32a on the air guide port 31 side, and the mounting portion 32b is the same as the fixing portion 32a. The side end portion on the side of the air guide port 31 is bent so as to rise forward. The attachment portions 32b of the pair of attachment plates 32, 32 are disposed to be separated from each other in the left-right direction so as to face each other, and the air guide cover 22 is provided over the two attachment portions 32b.

  The air guide cover 22 that is a dam member is made of a colored (for example, black) synthetic resin, and is a cover for covering and closing the air guide port 31. The air guide cover 22 has substantially the same shape as the air guide port 31 in a front view, and the outer diameter dimension of the air guide cover 22 is slightly larger than the outer dimension of the air guide port 31. Therefore, when the air guide cover 22 is overlapped with the air guide port 31, the air guide port 31 is blocked in front view. In addition, the left and right end portions of the air guide cover 22 are bent rearward to form attachment portions 22a and 22b. The wind guide cover 22 is installed on a pair of mounting plates 32 and 32 with the mounting portions 22a and 22b facing the mounting portions 32b, and mounting holes 22c are formed in the mounting portions 22a and 22b, respectively. ing.

  The attachment hole 22c penetrates the attachment portions 22a and 22b in the left-right direction, and a cylindrical collar member 26 is fitted into the attachment hole 22c. Further, a fastening member 25 is inserted into the collar member 26 so as to be relatively rotatable. The fastening member 25 fastens the wind guide cover 22 by fastening the attachment portions 22a and 22b and the attachment portion 32b of the attachment plate 32. It is attached to the attachment plate 32. Thus, the air guide cover 22 is configured to be relatively rotatable around the axis L1 of the fastening member 25 extending in the left-right direction, and can be angularly displaced between the closed position and the open position. . Here, the closed position is a position where the air guide cover 22 covers and closes the air guide port 31 as shown in FIGS. 11 and 12. On the other hand, the open position is a position where the air guide cover 22 is angularly displaced from the closed position to the front side. As shown in FIG. 13, the air guide cover 22 protrudes forward from the windshield body 21 and the air guide port 31 is formed. This is the position that opens forward (see also FIGS. 5 and 6). An accommodation hole 22d is formed in each of the attachment portions 22a and 22b of the air guide cover 22. The accommodation hole 22 d is a bottomed cylindrical hole and opens toward the mounting plate 32. Part of the configuration of the positioning mechanisms 23L and 23R is accommodated in the accommodation holes 22d on the left and right sides, respectively.

  The pair of left and right positioning mechanisms 23L and 23R are basically symmetrical. Hereinafter, the configuration of the left positioning mechanism 23L will be mainly described, and the configuration of the right positioning mechanism 23R will be mainly described with respect to differences from the configuration of the left positioning mechanism 23L. As shown in FIG. 9, the positioning mechanism 23 </ b> L includes a pressing member 41, a ball member 42, and a mounting plate 32. The pressing member 41, which is a pressing member, is a so-called compression coil spring and is accommodated in a compressed state in the accommodation hole 22d. Note that the pressing member 41 is not necessarily a compression coil spring, and may be a disc spring or a stretchable synthetic rubber. A spherical ball member 42 is placed on the opening side end of the pressing member 41.

  A part of the ball member 42 which is an engaging member protrudes in the axial direction from the accommodation hole 22d, and the protruding portion 42a is an attachment portion 32b of the attachment plate 32 (more specifically, the attachment portion 22a of the attachment portion 32b). , 22b). The ball member 42 is urged toward the mounting portion 32b by the pressing member 41, and the amount of protrusion from the accommodation hole 22d changes as the pressing member 41 expands and contracts. Further, the ball member 42 is angularly displaced about the axis L1 while a portion 42a protruding when the air guide cover 22 is angularly displaced is brought into contact with the mounting portion 32b. A plurality of positioning holes (three positioning holes in the present embodiment) 43a to 43c are formed in the mounting portion 32b of the mounting plate 32, which is an engaged member, on the locus when the protruding portion 42a moves. Yes.

  The three positioning holes 43a to 43c, which are engaged portions, are arranged at equal intervals on the locus (that is, around the axis L1). When the ball member 42 slides on the mounting portion 32b, the ball member 42 is fitted into the positioning holes 43a to 43c. The ball member 42 is fitted into the positioning holes 43a to 43c, so that the wind guide cover 22 is located at each position. Is positioned. The positions where the air guide cover 22 is positioned are, for example, three positions, that is, a closed position, an open position, and an intermediate position. In the closed position, the ball member 42 is fitted into the first positioning hole 43a that is the hole farthest from the fixed portion 32a among the three positioning holes 43a to 43c, and the most of the three positioning holes 43a to 43c in the closed position. The ball member 42 is fitted in the second positioning hole 43b, which is a hole close to the fixed portion 32a. Further, at the intermediate position, the ball member 42 is fitted into the third positioning hole 43c which is the remaining hole (that is, the middle hole). Thus, the positioning holes 43a to 43c are respectively formed in the left and right mounting plates 32 so as to form a pair. The hole diameters of the positioning holes 43a to 43c are smaller than the outer diameter of the ball member 42, and only a part of the protruding portion 42a of the ball member 42 is fitted into the positioning holes 43a to 43c. Thereby, it is easy to allow the ball member 42 to escape from the positioning holes 43a to 43c when the wind guide cover 22 is angularly displaced while securing the engaging force related to the positioning. Further, the protruding amount of the ball member 42 at the position to be positioned, that is, the engagement position, is the ball member 42 at the engaged position corresponding to between the closed position and the intermediate position and between the intermediate position and the open position. It is larger than the protruding amount.

  In the positioning mechanisms 23L and 23R configured as described above, the pressing member 41 and the ball member 42 are accommodated in the accommodation hole 22d as described above. Since the air guide cover 22 is formed by molding, the accommodation hole 22d is slightly tapered toward the bottom in consideration of the draft at the time of manufacturing the air guide cover 22, as shown in FIG. The outer diameter of 41 and the outer diameter of the ball 42 are formed to be equal to or smaller than the inner diameter of the bottom of the accommodation hole 22d. Therefore, the ball member 42 is immersed in the accommodation hole 22d, and a gap in the direction in which the air guide cover 22 is angularly displaced is formed between the opening end of the accommodation hole 22d. In the positioning mechanisms 23L and 23R of the present embodiment, the center axes L2 of the left and right accommodation holes 22d are substantially aligned (that is, the left and right accommodation holes 22d are coaxial with a predetermined center axis L2). Therefore, it is conceivable that the air guide cover 22 is loose due to the gap.

  In order to reduce such backlash, in the positioning mechanisms 23L and 23R, the left and right positioning holes 43a to 43c are arranged shifted in the circumferential direction (see FIG. 9). More specifically, each of the positioning holes 43 a to 43 c of the left positioning mechanism 23 </ b> L has an angle α (for example, 1 to 4) in the circumferential direction with respect to the positioning holes 43 a to 43 c forming a pair with the right positioning mechanism 23 </ b> R. (About 5 degrees). In the present embodiment, the left first positioning hole 43a is arranged to be shifted counterclockwise by an angle α with respect to the right first positioning hole 43a, and the same applies to the second positioning hole 43b and the third positioning hole 43c. It is arranged to shift to. Then, as shown in FIG. 14, each ball member 42 engages with each of the pair of first positioning holes 43a and 43a in a state of being displaced from each other in the circumferential direction. Since the accommodation hole 22d is basically positioned between the left and right ball members 42 in the circumferential direction in a side view, the centers O1 and O2 of the first positioning holes 43a and 43a are located on the central axis L2 of the accommodation hole 22d. On the other hand, the circumferential direction is shifted to one side and the other side (that is, the shifted directions are opposite to each other). As a result, one ball member 42 comes into contact with one opening end in the circumferential direction of the accommodation hole 22d, and the other ball member 42 comes into contact with the other opening end in the circumferential direction of the accommodation hole 22d. Then, the angular displacement of the wind guide cover 22 is restricted in either the circumferential direction or the other direction, and the play in the circumferential direction of the wind guide cover 22 can be suppressed. The positioning mechanisms 23 </ b> L and 23 </ b> R configured in this way are covered from the front by a cover member 24 provided on the windshield body 21.

  As shown in FIG. 6, the cover member 24 has a pair of side cover portions 51 </ b> L and 51 </ b> R and an air guide portion 52. The pair of side cover portions 51L and 51R have a symmetrical shape, and are arranged apart in the left-right direction so as to be located on both the left and right sides of the air guide port 31, respectively. That is, the side cover portions 51L and 51R are positioned in front of the attached portions 15e and 15f, respectively. The side cover portions 51L and 51R are fastened together with the windshield main body 21 to the attached portions 15e and 15f by the fastening member 17c. Further, the side cover portions 51L and 51R cover the positioning mechanisms 23L and 23R and the mounting plate 32 from the front so as not to be seen from the front, and are fastened to the mounting plates 32. In the windshield main body 21, a portion to which the attachment plate 32 is attached is subjected to roughening or the like so that the positioning mechanisms 23L and 23R and the attachment plate 32 cannot be seen from behind.

  Further, the side surface portions of the side cover portions 51L and 51R on the side of the air guide port 31 are formed in accordance with the shapes of the left and right side surface portions (that is, the mounting portions 22a and 22b) of the air guide cover 22 in a plan view. In the side cover portions 51L and 51R, the side portion on the side opposite to the air guide port 31 in the left-right direction is inclined downward toward the air guide port 31 side, and is separated from the opposite side portion so as to protrude downward. The design member 53 is extended. The design member 53 is fastened together with the windshield main body 21 to the attached portions 15e and 15f by the fastening member 17c. Moreover, the wind guide part 52 is integrally provided in the lower end part of the side cover parts 51L and 51R so that it may span over them.

  The air guide portion 52 is formed in a substantially V shape in front view in accordance with the shape of the lower edge portion of the air guide port 31, and extends along the lower edge portion of the air guide port 31 so as to be positioned below the air guide port 31. Are arranged. As shown in FIG. 12, the lower end portion 52a of the air guide portion 52 abuts on the surface of the windshield main body 21, and its intermediate portion gradually moves away from the windshield main body 21 as it proceeds from the lower end portion 52a to the upper end portion 52b. Standing diagonally up behind. That is, the intermediate portion 52c of the air guide portion 52 is formed so as to extend toward the air guide cover 22 located at the open position. Therefore, the traveling wind flowing along the windshield body 21 is separated from the windshield body 21 by the wind guide portion 52 and guided to the wind guide cover 22. The traveling wind guided to the wind guide cover 22 can flow toward the wind guide port 31 by changing its flow by hitting the wind guide cover 22.

  Further, the upper end portion 52b of the wind guide portion 52 has a step formed so as to be retracted toward the windshield body 21, and the tip portion 22e of the wind guide cover 22 in the closed position is seated on the lowered portion. It is supposed to be. Further, a seal member 55 is attached to the upper end portion 52b, and a gap generated between the front end portion 22e and the upper end portion 52b of the air guide cover 22 seated on the step is filled with the seal member 55. Yes. As described above, the seal member 55 is attached to the surface of the cover member 24 on the side of the air guide port 31, and the cover member 24 and the cover member 24 are guided when the air guide cover 31 is closed and the air guide port 31 is closed. The traveling wind is prevented from entering through the gap between the wind cover 22 and the wind cover 22. Further, the base end portion 22 f of the air guide cover 22 located at the closed position is located away from the upper edge portion of the air guide port 31. A guide portion 33 is disposed on the upper edge portion of the wind guide port 31 of the windshield body 21 so as to fill the space between the base end portion 22 f of the wind guide cover 22 and the upper edge portion of the wind guide port 31.

  The guide portion 33 fills a space between the base end portion 22f of the air guide cover 22 and the upper edge portion of the air guide port 31, and travels to the air guide port 31 while preventing the traveling wind from flowing upward along the windshield body 21. It has a function of guiding the wind and adjusting the flow of air taken into the air guide port 31. The guide portion 33 has a flange portion 33a and a guide portion 33b, and the flange portion 33a protrudes forward (in more detail, obliquely forward and downward) from the upper edge portion of the air guide port 31. The front end portion 33c of the flange portion 33a hangs downward, and a rubber cover 56 is attached to the front surface of the front end portion 33c. The rubber cover 56 is colored, and the rubber cover 56 can reduce reflected light generated by reflection of sunlight, streetlight light, and the like on the front surface of the front end portion 33 c. A guide portion 33b is integrally formed with the front end portion 33c of the flange portion 33a.

  The guide portion 33b is folded back from the front end portion of the flange portion 33a and extends rearward. The front end of the guide portion 33 b protrudes rearward from the back surface of the windshield body 21. By being formed in this way, the guide portion 33b can take the traveling wind into the air guide 31 and guide the air taken into the air guide 31 backward (that is, toward the driver's chest). . As a result, the air can be prevented from diffusing diagonally upward (that is, toward the driver's head), and the negative pressure around the driver's chest can be reduced. The rear end of the guide portion 33b does not hit the meter visor 4 when the windshield body 21 is lowered to the lower position.

  As shown in FIG. 12, the air guide cover 22 is integrally provided with an operation lever 57 at the rear end of the right attachment portion 22b. The operation lever 57 extends rearward from the right attachment portion 22b. Exist. The rear end portion of the operation lever 57 is located behind the back surface of the windshield body 21, and the driver can pick and push the rear end portion with a finger. When the driver pushes the operation lever 57 forward, the wind guide cover 22 rotates clockwise, and is angularly displaced from the closed position to the intermediate position or from the intermediate position to the open position (see FIG. 13). On the other hand, when the operation lever 57 is picked up and pulled down, the wind guide cover 22 rotates counterclockwise, and is angularly displaced from the open position to the intermediate position or from the intermediate position to the closed position (see FIG. 12). The operation lever 57 is located above the meter visor 4 when the windshield body 21 is located at the upper position, and the operation lever 57 provided integrally with the wind guide cover 22 opens and closes the wind guide cover 22. Can be done by the driver. When the windshield body 21 is lowered to the lower position, the operation lever 57 is lowered together with the windshield body 21 so as to be hidden in front of the meter visor 4 when viewed from the driver. The meter visor 4 is not hit.

  In the windshield 10 configured as described above, the air guide port 31 is formed in the lower region of the windshield main body 21 as shown in FIG. 5, so that a large amount of air taken in is placed around the chest of the driver. The negative pressure generated around the chest of the driver can be reduced. Thereby, the effect which suppresses that a driver | operator is pushed ahead can be improved. Further, in the windshield 10, as shown in FIG. 13, traveling wind flows along the region below the windshield body 21 (see arrow A). The traveling wind that flows along the windshield body 21 is peeled from the windshield body 21 at the lower end of the wind guide portion 52, and then flows along the wind guide portion 52. When the windshield body 21 is raised to the upper position and the wind guide cover 22 is angularly displaced to the open position, the traveling wind that flows along the wind guide portion 52 is generated at the upper end portion 52b of the wind guide portion 52. 52, it is led to the lower surface of the wind guide cover 22 and once blocked there. The dammed wind is guided rearward in the direction of flowing by the guide portion 33b of the guide portion 33 to the air guide port 31 (see arrow B). By directing the flow direction by the guide portion 33b in this way, it is possible to suppress the air taken in through the air guide port 31 from diffusing upward, and a larger amount of air is taken in and the chest of the driver is taken. Can lead to around. Thereby, it can further suppress that a driver is pushed ahead.

  In the windshield 10, side cover portions 51 </ b> L and 51 </ b> R that cover the mounting plate 32 are provided on both the left and right sides of the air guide port 31. The side cover portions 51L and 51R serve as partition members that divide the left and right sides of the air guide port 31 and other portions, and block the traveling wind flowing in the left and right direction of the air guide port 31. That is, the side cover portions 51L and 51R projecting forward from the surface of the windshield main body 21 guide the traveling wind to the air guide port 31 so that the wind taken into the air guide port 31 does not escape to the left and right sides of the air guide port 31. It is like that. As a result, a greater amount of traveling wind can be collected at the air inlet 31 and a larger amount of air can be guided to the driver.

  Further, in the windshield 10, the windshield main body 21 can be angularly displaced between the open position and the closed position, and rain can be prevented from entering from the air guide port 31 by angularly displacing to the closed position. In addition, even when angularly displaced to the open position, the wind guide cover 22 is disposed above the wind guide port 31 so as to protrude forward with respect to the windshield body 21, and thus acts like a kite. Thereby, even if it arrange | positions the wind guide cover 22 in an open position, it can suppress that rain enters from the wind guide port 31. FIG.

  In the windshield 10, the air guide cover 22 is positioned by positioning mechanisms 23L and 23R at each position. In the positioning mechanisms 23L and 23R, the ball member 42 is urged toward the positioning holes 43a to 43c by the pressing member 41 and engaged with the positioning holes 43a to 43c. Therefore, the engagement force is improved and the air guide cover 22 can be positioned at each position. Further, since the positioning mechanisms 23L and 23R are arranged on the left and right sides of the air guide cover 22, the air guide cover 22 can be held from both the left and right sides. Thereby, the holding force of the wind guide cover 22 can be increased, and the play of the wind guide cover 22 can be suppressed. Furthermore, since the paired positioning holes 43a to 43c are arranged shifted in the circumferential direction, it is possible to suppress the play in the circumferential direction of the wind guide cover 22 when the wind guide cover 22 is positioned at each position. . Further, by shifting the positioning holes 43a to 43c, the ball member 42 is sandwiched between the opening end of the accommodation hole 22d and the opening ends of the positioning holes 43a to 43c to restrict the angular displacement of the air guide cover 22. Become. Thus, by sandwiching the ball member 42 between the open ends, the contact area where the ball member 42 contacts the air guide cover 22 and the mounting plate 32 can be increased, and the force for sandwiching the ball member 42 is increased. be able to. Thereby, the holding force holding the air guide cover 22 at each position can be increased.

  Furthermore, in the windshield 10, the windshield body 21 can be raised and lowered between the lower position and the upper position by the lifting mechanism 16. In the lower position, the upper end of the windshield body 21 is located at a low position, so that the traveling wind that flows above the windshield body 21 hits the driver's head, and the traveling wind is somewhat guided around the driver's chest. Therefore, the negative pressure around the driver's chest is eliminated. In such a lower position, the air guide port 31 is located on the front side of the meter visor 4, and the air taken in from the air guide port 31 is blocked by the meter visor 4. By doing so, it is suppressed that the wind taken in from the baffle 31 hits the driver.

  Further, when the windshield body 21 is raised to the upper position by the elevating mechanism 16 in order to improve the windproof effect on the driver, the wind is not guided around the driver's chest, and the negative pressure around the chest increases. . Therefore, in the upper position, the air guide port 31 is disposed so as to be positioned higher than the meter visor 4, and the wind taken from the air guide port 31 is guided around the driver's chest. Thereby, it can suppress that a driver | operator is pushed ahead with a negative pressure.

  Further, in the windshield 10, the air guide port 31 is formed in a V shape and has a large opening area. As a result, a larger amount of air can be taken in from the air inlet 31 and the negative pressure around the driver's chest can be further reduced.

[Other Embodiments]
In the windshield 10, the wind guide cover 22 is configured to be angularly displaced. However, the wind guide cover 22 slides linearly or curvedly in the vertical direction or the horizontal direction along the windshield body 21 (in the vertical direction or in the vertical direction). It may be configured to be displaced in the left-right direction. When the air guide cover 22 slides, the positioning holes 43a to 43c of the positioning mechanisms 23L and 23R are shifted in the sliding direction, shifted in the direction crossing the sliding direction, and a combination thereof, thereby suppressing back and forth and back and forth play. Can do.

  In the windshield 10, the positioning holes 43 a to 43 c are formed in each of the left and right mounting plates 32, but the positioning holes 43 a to 43 c may be formed only in one of the mounting plates 32. The paired positioning holes 43a to 43c may be formed so as to be biased to one of the two mounting plates 32, and the paired positioning holes 43a to 43c are formed in the mounting plate 32 while being shifted in the radial direction instead of the circumferential direction. May be. Further, if only positioning is required, it is not necessary to form the paired positioning holes 43a to 43c in a shifted manner. Further, the positions of the paired positioning holes 43a to 43c are shifted in order to suppress the play, but even if the positions of the accommodation holes 22d are shifted from each other without shifting the positions of the paired positioning holes 43a to 43c. Similar effects can be obtained. Further, although the positioning holes 43 a to 43 c are formed in the mounting plate 32, the positioning may be performed by forming a convex portion in the mounting plate 32 and forming a concave portion in the ball member 42. Further, in the present embodiment, the engaging member is constituted by the spherical ball member 42, but it may be conical or frustoconical, and the diameter decreases toward the mounting plate 32 that is the engaged member. Any shape can be used.

  In the windshield 10, the pressing member 41 presses the ball member 42 in the direction along the central axis L2, but the pressing direction of the pressing member 41 may be different for each of the positioning mechanisms 23L and 23R. For example, the positioning holes 43a to 43c are formed so that the orientations of the positioning holes 43a to 43c viewed from the accommodation hole 22d are different for the positioning mechanisms 23L and 23R. More specifically, the positioning mechanisms 23L and 23R are configured such that the pressing member 41 presses the ball member 42 in different directions with respect to a plane perpendicular to the central axis L2 of the accommodation hole 22d.

  In the windshield 10, the guide portion 33 b is formed short so that it does not hit the meter visor 4 when the windshield body 21 is lowered. However, when the windshield 10 does not have the lifting mechanism 16, the guide portion 33b may be formed long. By doing so, more air can be guided around the driver's chest, and the negative pressure around the chest can be eliminated. Moreover, in the windshield 10, the guide part 33 and the air guide part 52 are not necessarily required. The windshield 10 only needs to have at least the wind guide cover 22, and the wind guide cover 22 may be used in combination with either the guide portion 33 or the wind guide portion 52. Further, the air guide portion 52 is not necessarily arranged along the lower edge portion of the air guide port 31, and may be disposed below the air guide port 31.

  In the windshield 10, the air guide cover 22 is manually opened and closed by the operation lever 57, but it is not always necessary, and may be configured to be opened and closed using an actuator such as an electric motor or a cylinder mechanism. .

  In the windshield 10, various configurations together with the windshield main body 21 are fastened to the attachment portions 15 e and 15 f by the fastening members 17 a to 17 c, but it is not always necessary to configure as such. For example, the attachment plate 32 and the cover member 24 may be directly attached by welding or engaging with the windshield main body 21. Further, the fastening members 17a to 17c are not necessarily bolts, and may be rivets or the like.

  The windshield body 21 is a molded product of a synthetic resin, and a weld line may be generated in a region below the air inlet 31. In order to make such a weld line inconspicuous, the windshield main body 21 hides the weld line by roughing the region where the weld line is generated or applying a design.

  Although the windshield 10 of the present embodiment is provided in the motorcycle 1, the vehicle provided may be other than the motorcycle 1. For example, the vehicle may be provided in a four-wheeled vehicle such as an all-terrain vehicle (ATV), a three-wheeled vehicle, or the like.
