Description

[Technical field]

[0001] The present invention relates to a windshield mounting structure that suppresses wind that a driver of a vehicle experiences while traveling. [Background technology]

[0002] Some vehicles, such as motorcycles, are equipped with a windshield to reduce the wind that the driver is exposed to while traveling (for example, Patent Document 1). Some windshields are provided so that their position can be adjusted relative to the vehicle body. In Patent Document 1, the position of the windshield can be adjusted relative to the vehicle body by loosening fastening members that secure the windshield to the vehicle body and sliding the windshield. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5495909 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the structure of Patent Document 1, the position of the operating element (fastening member) for adjusting the position is also limited, and the degree of freedom in design is low.

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a windshield mounting structure that allows the position of the windshield to be adjusted with a simple structure and simple operation. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objective, the windshield mounting structure of the present invention is a windshield mounting structure that suppresses the wind experienced by the driver of the vehicle, and is equipped with an adjustment support mechanism that supports the windshield so that it can slide freely relative to the vehicle body, an operator that is operated when adjusting the position of the windshield, and a wire that connects the adjustment support mechanism and the operator, and when the operator is operated, the adjustment support mechanism is switched between a position adjustable state and a position unadjustable state via the wire.

[0007] According to this configuration, the windshield position can be switched between an adjustable state and an unadjustable state by operating the operating element. In other words, while operating the operating element with one hand, the windshield can be slid with the other hand. This allows the windshield position to be adjusted with a simple structure and simple operation. In addition, because the operating force is transmitted via a wire, the operating element and the adjustment support mechanism can be arranged separately, improving the degree of freedom in design.

[0008] In the present invention, the adjustment support mechanism may have a first biasing member that biases the adjustment support mechanism in a direction that renders it unable to be adjusted in position, and the adjustment support mechanism may be adjusted in position against the bias of the first biasing member by operating the control in a first direction. With this configuration, the force applied by operating the control is in only one direction (the first direction), and the adjustment support mechanism returns in the direction opposite to the first direction due to the biasing force of the first biasing member. This simplifies the configuration of the adjustment support mechanism.

[0009] In this case, the manipulator may have a second biasing member that biases the manipulator in a direction that makes the manipulator unable to be adjusted in position, and the manipulator may be operated in a first direction against the bias of the second biasing member. With this configuration, the movement of the manipulator can be assisted by the first and second biasing members. This allows a flexible material to be used for the wire, improving the freedom of material selection.

[0010] In the present invention, the adjustment support mechanism may be for changing the position of the windshield in stages, the adjustment support mechanism including a slide member to which the windshield is attached and which is supported slidably on the vehicle body, and a switching member supported on the vehicle body and moved by the operation of the operating element to switch the slide member between a slidable state and a non-slidable state, the slide member has a plurality of positioning parts arranged side by side in the sliding direction, the switching member has locking parts which lock with the positioning parts, the operating element is manually operated to move the locking parts via the wire rod to switch between locking and unlocking of the locking parts with respect to the positioning parts, the locking parts move to the locked position in the position non-adjustable state, and the locking parts move to the unlocked position in the position adjustable state. With this configuration, an electric motor or the like is not required, and the adjustment support mechanism can be made with a simple structure.

[0011] In this case, the operating element and the locking portion may be disposed apart in the front-rear direction and the width direction of the vehicle body, and may be connected to each other by the wire. According to this configuration, by connecting them by the wire, the operating element and the locking portion can be disposed apart from each other. Therefore, interference between the operating element and the locking portion and other components can be prevented. This improves the degree of freedom in component arrangement.

[0012] In this case, the locking portion may be disposed in a vehicle width direction central portion of the vehicle body, and the operating element may be provided at a position offset in the vehicle width direction from the vehicle width direction central portion of the vehicle body. According to this configuration, since the operating element is provided at a position offset in the vehicle width direction from the vehicle width direction central portion of the vehicle body, it is possible to prevent interference with a component disposed in the vehicle width direction central portion.

[0013] When the switching member has the locking portion, the sliding member may have a guide portion that slides relative to the vehicle body. With this configuration, by separating the guide function and the engagement function, the structure of the adjustment support mechanism can be simplified compared to a case where both functions are performed by one. In addition, since the load is received at positions other than the engagement position (for example, the guide position), the load is dispersed and can be prevented from concentrating on the engagement portion.

[0014] In the present invention, the slide member may be formed with an engagement prevention surface that prevents the engagement portion from moving toward the engagement position when the engagement portion is in the unlocked position. With this configuration, it is not necessary to continue to apply a force to the operating element manually, and operability is improved. Effect of the Invention

[0015] According to the windshield mounting structure of the present invention, the position of the windshield can be adjusted with a simple structure and simple operation. [Brief description of the drawings]

[0017] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a side view showing the front of a motorcycle, which is a type of vehicle equipped with a windshield mounting structure according to a first embodiment of the present invention. In this specification, "right" and "left" refer to the right and left as seen by a driver riding in the vehicle. Additionally, "front" and "rear" refer to the front and rear of the vehicle in the traveling direction.

[0018] The body frame FR of the motorcycle of this embodiment has a main frame 1 constituting a front half thereof and a rear frame 2 constituting a rear half thereof. The rear frame 2 is connected to the rear of the main frame 1.

[0019] A front fork 6 is rotatably supported via a steering shaft (not shown) on a head pipe 4 at the front end of the main frame 1. A front wheel 8 is attached to the lower end of the front fork 6. A handlebar 10 is attached to the upper end of the front fork 6.

[0020] A swing arm bracket 12 is provided at the rear end of the main frame 1. A front end of a swing arm 13 is supported by the swing arm bracket 12 so as to be able to swing up and down about a pivot shaft 14. A rear wheel (not shown) is attached to the rear end of the swing arm 13.

[0021] An engine E, which serves as a drive source, is attached below the main frame 1 and in front of the swing arm bracket 12. The engine E drives a rear wheel (not shown) via a power transmission member (not shown) such as a chain. A fuel tank 16 is disposed on top of the main frame 1, and a seat 18 on which a rider sits is attached to the rear frame 2.

[0022] A resin front cowl 20 is attached to the front of the vehicle body, and a headlamp 22 is attached to the front cowl 20. The front cowl 20 is detachably attached to the vehicle body frame FR via a cowl stay 24. The front cowl 20 of this embodiment covers the area in front of the head pipe 4. The shape of the front cowl 20 is not limited to this. The cowl stay 24 is formed by connecting a plurality of steel pipes by welding.

[0023] A windshield 26 made of transparent resin is disposed on the upper end of the front cowl 20. The windshield 26 suppresses the wind that the driver of the vehicle is exposed to while traveling. The windshield 26 is also detachably attached to the body frame FR via the cowl stay 24.

[0024] The windshield 26 is attached to the cowl stay 24 (vehicle body) so as to be freely slidable. In this embodiment, the windshield 26 is freely slidable in the up-down direction with respect to the vehicle body. More specifically, the sliding direction is inclined upward and backward.

[0025] 2, the windshield 26 is slidably supported on the cowl stay 24, which is a part of the vehicle body, via an adjustment support mechanism 28. That is, the adjustment support mechanism 28 supports the windshield 26 so that it can slide in the sliding direction SD relative to the vehicle body. In this embodiment, the adjustment support mechanism 28 is attached to the cowl stay 24.

[0026] An operator 30 is provided on the vehicle body side, and the adjustment support mechanism 28 and the operator 30 are connected by a wire 32. The operator 30 is manually operated when adjusting the position of the windshield 26. In other words, by operating the operator 30, the adjustment support mechanism 28 is switched between a position adjustable state and a position unadjustable state. In detail, when an operating force is applied to the operator 30, the position is adjustable, and when the operating force is released, the position is unadjustable. The operating force applied to the operator 30 is transmitted to the adjustment support mechanism 28 via the wire 32.

[0027] In this embodiment, the operator 30 is a lever rotatably supported on the vehicle body, and the wire 32 is a metal wire. The operator 30 and the wire 32 are not limited to this. The operator 30 and the wire 32 will be described in detail later.

[0028] The adjustment support mechanism 28 of this embodiment changes the position of the windshield 26 in stages. Specifically, the adjustment support mechanism 28 has a slide member 34 and a switching member 36. The windshield 26 is attached to the slide member 34, which is supported slidably relative to the vehicle body (cowl stay 24). The windshield 26 is detachably attached to the slide member 34 by a plurality of fastening members 25.

[0029] The slide member 34 is formed in a substantially U-shape when viewed from the front. Specifically, the slide member 34 is made of a steel plate material, and as shown in Fig. 3, has a plate portion 42 located in the center of the vehicle body in the vehicle width direction, and a pair of left and right branch portions 44, 44 connected to the plate portion 42. The branch portions 44 extend from the plate portion 42 in the vehicle width direction and then extend in the sliding direction.

[0030] The sliding member 34 has a guide portion 35 that is slidably guided relative to the vehicle body. In this embodiment, the guide portion 35 is provided at three locations, namely, both sides in the vehicle width direction and a middle portion in the vehicle width direction. In other words, the guide portion 35 is provided on each of the plate portion 42 and the left and right branch portions 44, 44.

[0031] As shown in Fig. 2, the guide portions 35 provided on the left and right branch portions 44 are formed of slit-shaped grooves extending in the sliding direction. As shown in Fig. 3, the guide portion 35 provided on the central plate portion 42 is formed of an insertion hole 35a and a fastening member 46 inserted therethrough. In this embodiment, two insertion holes 35a are provided side by side in the sliding direction. However, the shape, number and arrangement of the guide portions 35 are not limited to this.

[0032] The shield mounting portion 24a is provided at a position corresponding to the guide portion 35 on the cowl stay 24. That is, the shield mounting portion 24a is also provided at three locations, namely, both sides in the vehicle width direction and the middle portion in the vehicle width direction.

[0033] 2, the shield mounting portion 24a corresponding to the guide portion 35 of the branch portion 44 is composed of a screw hole 48 and a fastening member 45 screwed into the screw hole 48. The screw hole 48 is, for example, a welded nut welded to the cowl stay 24. That is, the fastening member 45 is inserted into the guide portion 35 (through groove) of the branch portion 44 and tightened into the screw hole 48 of the shield mounting portion 24a, whereby the slide member 34 of the adjustment support mechanism 28 is slidably supported in a position adjustable state. In this way, the guide portion 35 (groove) is guided by the fastening member 45, whereby the slide member 34 of the adjustment support mechanism 28 slides relative to the cowl stay 24.

[0034] As shown in FIG. 3, the shield mounting portion 24b corresponding to the guide portion 35 of the central plate portion 42 is formed of a slit-shaped groove extending in the sliding direction. That is, the fastening member 46 is inserted through the insertion hole 35a of the plate portion 42 and the shield mounting portion 24b (through groove) of the cowl stay 24, and is fastened by a nut 50 (FIG. 2) to be prevented from coming off. As a result, the slide member 34 of the adjustment support mechanism 28 is slidably supported by the cowl stay 24 in the position adjustable state. In this way, the fastening member 46 (guide portion 35) is guided by the shield mounting portion 24b (groove), so that the slide member 34 of the adjustment support mechanism 28 slides relative to the cowl stay 24. As described above, the operation of the adjustment support mechanism 28 is stabilized by being supported at three points.

[0035] Positioning portions 38 are provided on the plate portion 42 of the slide member 34. The positioning portions 38 are provided side by side on the slide member 34 in the sliding direction. In this embodiment, the positioning portions 38 are made of bent wire. The positioning portions 38 are provided on one surface of the plate portion 42, specifically, on the upper surface.

[0036] The switching member 36 shown in Fig. 2 is rotatably supported by the vehicle body (cowl stay 24). In detail, the switching member 36 is rotatably supported by the cowl stay 24 by a pivot member 52 (Fig. 5) extending in the vehicle width direction. The pivot member 52 is a fastening member such as a bolt. The switching member 36 rotates by operating the operating element 30, thereby switching the sliding member 34 between a slidable state and a non-slidable state.

[0037] 7, the switching member 36 has a locking portion 40 that locks with the positioning portion 38. In this embodiment, the locking portion 40 is made of a locking claw that locks with the wire 38. The locking claw 40 is locked with the wire 38 from the other surface side (lower side) of the plate portion 42. The positioning portion 38 and the locking portion 40 are not limited to this.

[0038] The locking claw 40 of this embodiment has a pair of claw pieces 40a, 40b arranged in the sliding direction (substantially the up-down direction) and a groove portion 40c between the pair of claw pieces 40a, 40b. The wire 38 is fitted into this groove portion 40c. The pair of claw pieces 40a, 40b have different lengths. Specifically, the upper claw piece 40a is shorter than the lower claw piece 40b.

[0039] The locking claw 40 of this embodiment is detachably provided on the main body 36a of the switching member 36. In detail, the locking claw 40 is rotatably supported on the main body 36a of the switching member 36 by a pivot member 54 extending in the vehicle width direction. The pivot member 54 is, for example, a fastening member such as a bolt. In this embodiment, the main body 36a of the switching member 36 is made of a metal material, and the locking claw 40 is made of a resin (for example, nylon 66).

[0040] The plate portion 42 is provided with a through hole 55 through which the locking claw 40 passes. In this embodiment, two through holes 55 are provided side by side in the front-rear direction. The wire 38 is arranged such that a portion of it crosses above the through hole 55 in the vehicle width direction. The positioning portion 38 is formed by fixing a bent wire to the plate portion 42 by welding. The portion of the wire extending in the vehicle width direction constitutes the positioning portion 38.

[0041] In this embodiment, the positioning portions 38 (portions of the wire extending in the vehicle width direction) are provided in four locations: above the two through holes 55, above the front of the plate portion 42, and above the rear of the plate portion 42. That is, the adjustment support mechanism 28 in this embodiment is configured to allow four-stage position adjustment. However, the position adjustment is not limited to four stages.

[0042] An engagement prevention surface 56 is formed on the plate portion 42 in the center of the slide member 34. In this embodiment, the lower surface of the plate portion 42 constitutes the engagement prevention surface 56. The engagement prevention surface 56 is formed along the sliding direction. The engagement prevention surface 56 prevents the locking portion 40 from moving toward the locking position (upward in this embodiment) to the unlocked position. The engagement prevention surface 56 does not have to be the lower surface of the plate portion 42, and may be formed of a separate member from the plate portion 42. However, by having the plate portion 42 also serve as the engagement prevention surface 56, welding, fastening, etc. are not required, and the structure can be simplified compared to when it is formed of a separate member.

[0043] The adjustment support mechanism 28 further has a first biasing member 64 that biases the adjustment support mechanism 28 in a direction that renders the adjustment support mechanism 28 unable to adjust its position. The first biasing member 64 is, for example, a coil spring, and as shown in Fig. 2, one end is engaged with the cowl stay 24 and the other end is engaged with the switching member 36 of the adjustment support mechanism 28. The first biasing member 64 applies a biasing force to the switching member 36 in the direction of arrow A1. Note that the first biasing member 64 is omitted in Figs. 5 and 6.

[0044] The operating element 32 and the locking portion 40 are disposed apart in the front-rear direction (FIG. 4) and in the vehicle width direction (FIG. 5) of the vehicle body, and are connected to each other by the wire 32. In detail, as shown in FIG. 5, the locking portion 40 is disposed in the center of the vehicle body in the vehicle width direction, and the operating element 30 is provided at a position offset in the vehicle width direction (left side in this embodiment) from the center of the vehicle body in the vehicle width direction.

[0045] One end 32a of the wire 32 is connected to the operator 30, and the other end 32b is connected to the switching member 36 of the adjustment support mechanism 28. In detail, one end 32a of the wire 32 shown in Fig. 6 is engaged with a locking groove 30a provided in the operator 30. Meanwhile, the other end 32b of the wire 32 is engaged with a locking groove 36b provided in the switching member 36. As shown in Fig. 5, the wire 32 is protected by a resin covering material 58 except for both ends 30a, 30b.

[0046] The operator 30 has a support portion 60 and an operating portion 62. The support portion 60 is formed by bending a metal plate, and is rotatably supported by the cowl stay 24. The support portion 60 is rotatably supported by the cowl stay 24 by a pivot support member 66 extending in the vehicle width direction. The pivot support member 66 is, for example, a fastening member such as a bolt.

[0047] The operating portion 62 is a portion that is manually operated by the driver and is made of, for example, a resin such as plastic. The operating portion 62 is detachably attached to the support portion 60 by a fastening member 68 such as a bolt.

[0048] The operating element 30 further has a second biasing member 70 that biases the operating element 30 in a direction that makes the position unadjustable. The second biasing member 70 is made of, for example, a coil spring, and as shown in Fig. 7, one end is engaged with the operating portion 62 of the operating element 30, and the other end is engaged with the cowl stay 24. The second biasing member 70 applies a biasing force to the operating portion 62 in the direction of arrow A2.

[0049] The procedure for adjusting the position of the windshield 24 in this embodiment will be described. First, the operating portion 62 of the operating element 30 shown in Fig. 4 is operated in the first direction D1. This causes the operating element 30 to rotate around the pivot member 66 (downward in Fig. 4) against the biasing force of the second biasing member 70.

[0050] When the operating element 30 rotates, the wire 32 is pulled in the direction of arrow A3, and the switching member 36 of the adjustment support mechanism 28 rotates around the pivot member 52 (first direction D1) by the wire 32 against the biasing force of the first biasing member 64. When the switching member 36 rotates, the locking portion (locking claw) 40 disengages from the positioning portion 38 (wire), and the position becomes adjustable.

[0051] When the position is adjustable, the operation of the operating portion 62 of the operator 30 is released, and the slide member 34 of the adjustment support mechanism 28 is slid. In the position adjustable state shown in Fig. 8A, a force is applied to the switching member 36 around the pivot member 52 in the second direction D2 due to the biasing force of the first biasing member 64 (Fig. 4).

[0052] In this state, the slide member 34 is slid in the direction of the arrow A4 to the position indicated by the two-dot chain line. At this time, the slide member 34 moves while its engagement prevention surface 56 slides on the claw piece 40b of the locking claw 40. In this embodiment, the locking claw 40 is made of resin, so that sliding between metals is avoided. Note that Figs. 8A and 8B illustrate an example in which the slide member 34 is adjusted from the first position P1 to the second position P2.

[0053] When the claw piece 40b of the locking claw 40 reaches a position from the engagement prevention surface 56 to the through hole 55 of the plate portion 42 of the slide member 34, the locking claw 40 enters the through hole 55 and rotates to the position shown by the dotted line due to the biasing force (force in the second direction D2) of the first biasing member 64 (Figure 4).

[0054] 8B shows a state in which the position adjustment to the second position P2 has been completed. That is, the claw pieces 40a, 40b of the locking claw 40 pass through the through-hole 55 of the plate portion 42 and are locked to the positioning portion 38 (wire). Even in this state, a force is acting on the switching member 36 (locking claw 40) in the second direction D2 around the pivot member 52 due to the biasing force of the first biasing member 64 (FIG. 4). That is, the locking claw 40 is prevented from being released from the wire 38, and the position adjustment is disabled.

[0055] Also, since a force is applied to the operating element 30 shown in FIG. 4 in the second direction D2 around the pivot support 66 by the biasing force of the second biasing member 70, the operating element 30 returns to the position before operation (position unadjustable state).

[0056] In this embodiment, the wire 32 has a portion that is bent and guided in the cowl stay 24. The wire 32 is flexible and passes through the bent passage by bending and deforming. By using such a wire 32, interference between the power transmission mechanism and other components can be prevented and the power transmission direction can be easily changed, compared to a power transmission mechanism in which multiple link members are combined.

[0057] The operator 30 is disposed below the lower end of the meter or below the meter cover, thereby preventing the wire 32 and the support portion 60 from being exposed to the outside, thereby improving the aesthetic appearance of the vehicle.

[0058] According to the above configuration, the windshield 26 (FIG. 1) can be switched between a position adjustable state and a position unadjustable state by operating the operating element 30. In other words, while operating the operating element 30 with one hand, the windshield 24 can be slid with the other hand. This allows the position of the windshield 24 to be adjusted with a simple structure and simple operation.

[0059] The adjustment support mechanism 28 has a first biasing member 64 that biases the adjustment support mechanism 28 in a direction A1 that makes the adjustment mechanism 28 unable to adjust its position, and when the operating element 30 is operated in the first direction D1, the adjustment support mechanism 28 becomes able to adjust its position against the biasing force of the first biasing member 64. Therefore, the force exerted by the operation of the operating element 30 is only in one direction (first direction D1), and the force in the other direction (first direction D2) is returned by the biasing force of the first biasing member 64. This simplifies the configuration of the adjustment support mechanism 28.

[0060] Furthermore, the operating element 30 has a second biasing member 70 that biases the operating element 30 in a direction A2 that puts the operating element 30 in a position unadjustable state, and the operating element 30 is operated in the first direction D1 against the biasing force of the second biasing member 70. Therefore, the movement of the operating element 30 can be assisted by the first and second biasing members 64, 70. This eliminates the need for high rigidity in the wire material 32, improving the freedom of material selection.

[0061] Furthermore, by manually operating the operating element 30, the locking portion 40 moves via the wire 32, switching between locking and unlocking of the locking portion 40 with respect to the positioning portion 38, so that in the position unadjustable state of Fig. 8B the locking portion 40 moves to the locking position, and in the position adjustable state of Fig. 8A the locking portion 40 moves to the unlocked position. This eliminates the need for an electric motor or the like, allowing the adjustment support mechanism 28 to have a simple structure.

[0062] The operating element 30 and the locking portion 40 are disposed apart in the front-rear direction and width direction of the vehicle body (FIG. 5), and the two 30, 40 are connected by a wire 32. As a result, even if the operating element 30 and the locking portion 40 are disposed at positions spatially separated from each other, interference with other components can be prevented by connecting them by the wire 32. This improves the degree of freedom in component arrangement.

[0063] 5, the locking portion 40 is disposed in the center of the vehicle body in the vehicle width direction, and the operating element 30 is provided at a position offset in the vehicle width direction from the center of the vehicle body in the vehicle width direction. In this way, since the operating element 30 is provided at a position offset in the vehicle width direction from the center of the vehicle body in the vehicle width direction, the operating element 30 can be easily operated with one hand.

[0064] The slide member 34 has a guide portion 35 that slides relative to the vehicle body, and a positioning portion 38. By separating the guide function and the engagement function in this way, the structure of the adjustment support mechanism 28 can be simplified compared to a case in which both functions are performed by a single portion. In addition, since the load is received at positions other than the engagement position (for example, the guide position), the load can be prevented from concentrating on the engagement portion 40 or the positioning portion 38.

[0065] An engagement prevention surface 56 that prevents the locking portion 40 from moving toward the locking position when the slide member 34 is in the unlocked position shown in Fig. 8A is formed. This eliminates the need to continuously apply force manually to the operating element 30 (Fig. 4), improving operability.

[0066] 9 to 11 show a windshield mounting structure according to a second embodiment of the present invention. In the second embodiment, the same structures as those in the first embodiment are given the same reference numerals, and detailed description thereof will be omitted.

[0067] In the second embodiment, similarly to the first embodiment, when an operating force is applied to the operating element 30 in Fig. 9, the position can be adjusted, and when the operating force is released, the position cannot be adjusted. The operating force applied to the operating element 30 is transmitted to the adjustment support mechanism 28A via the wire 32. However, the structure of the adjustment support mechanism 28A is different from that of the adjustment support mechanism 28 in the first embodiment.

[0068] In the second embodiment, as shown in Fig. 11, the position is adjusted by locking a locking portion 40A consisting of a protrusion with a positioning portion (locking hole) 38A consisting of a through hole formed in a line in the sliding direction SD. The locking portion 40A is connected to the operation element 30 (Fig. 10) via a wire 32. In this embodiment, the locking hole 38A is formed in the sliding member 34, and four locking holes are provided in this embodiment. That is, the position of the windshield 26 can be adjusted in four stages. The number of locking holes 38A is not limited to four.

[0069] A spring force is applied to the locking portion (protrusion) 40A in the direction of the arrow AA1 by a first biasing member 64. Therefore, in a normal state in which no operating force is applied, the protrusion 40A penetrates any of the locking holes 38A and further passes through a through hole 80 formed in the cowl stay 24. As a result, the protrusion 40A is inserted into the through hole 80 of the cowl stay 24, preventing the protrusion 40A from moving in the sliding direction SD. Therefore, in the normal state in which the operating element 30 shown in FIG. 10 is not operated, the position of the windshield 26 cannot be adjusted.

[0070] When an operating force is applied to the operating element 30, that is, when the operating element 30 is operated in the direction of arrow AA2, the second biasing member 70 rotates in the direction of arrow AA3. As a result, the protrusion 40A is pulled in the direction of arrow AA4 against the spring force of the first biasing member 64 via the wire 32. When the wire 32 is pulled in the direction of arrow AA4, the protrusion 40A shown in FIG. 11 comes out of the through hole 80 of the cowl stay 24 and the locking hole 38A of the slide member 34. As a result, the slide member 34 becomes movable in the sliding direction SD relative to the cowl stay 24.

[0071] The slide member 34 is moved in the sliding direction SD, and when the desired locking hole 38A is positioned so as to match the protrusion 40A, the operating force of the operating element 30 is released (the operating element 30 is released). Then, the spring force of the first biasing member 64 pulls the protrusion 40A in the direction of arrow AA1, and the protrusion 40A is inserted into the desired locking hole 38A and the through-hole 80 of the cowl stay 24. This completes the position adjustment of the windshield 26.

[0072] The second embodiment in FIGS. 9 to 11 also provides the same effects as the first embodiment in FIGS. 1 to 8B.

[0073] The present invention is not limited to the above-described embodiment, and various additions, modifications, and deletions are possible without departing from the scope of the present invention. For example, in the above-described embodiment, an example in which the windshield mounting structure of the present invention is applied to a motorcycle is described, but the windshield of the present invention can also be applied to vehicles other than motorcycles, such as three-wheeled or four-wheeled vehicles for running on rough terrain. Therefore, such vehicles are also included in the scope of the present invention. [Explanation of symbols]
