JP7571082B2 - Windscreen device and saddle-type vehicle equipped with same - Google Patents

Description

The present invention relates to a windscreen device that is provided on a saddle-type vehicle and a saddle-type vehicle equipped with the same.

Traditionally, straddle-type vehicles equipped with a windscreen device in front of the handlebars to block wind from the front that occurs while driving are known. Windscreen devices are also known that allow the height and inclination angle of the windscreen to be manually changed according to the rider's preferences. For example, Patent Document 1 discloses such a windscreen device.

The windscreen device disclosed in Patent Document 1 includes a screen bracket that supports a windscreen, a support bracket provided with a rotation shaft that supports the screen bracket so that it can rotate back and forth, and a ratchet mechanism that locks the position of the screen bracket relative to the support bracket. The ratchet mechanism has a claw member rotatably provided on the support bracket, multiple engagement grooves arranged vertically on the screen bracket, and a torsion coil spring that biases the claw member so that it engages with the engagement grooves. The ratchet mechanism is configured to allow the screen bracket to rotate forward but restrict backward rotation. In addition, the ratchet mechanism is configured to allow backward rotation after the screen bracket has rotated forward by a predetermined angle.

In the above windscreen device, when the occupant rotates the windscreen forward, the claw member disengages from the engagement groove. This releases the lock on the screen bracket, allowing it to rotate. When the occupant rotates the windscreen further forward, the claw member engages with the groove below the engagement groove. This changes the height and tilt angle of the windscreen, and the screen bracket is locked in the changed position. Patent Document 1 describes how such a mechanism makes it easy to manually change the tilt angle of the windscreen.

JP 2011-20616 A

In the windscreen device disclosed in Patent Document 1, the windscreen is locked by the engagement of the engagement claws and engagement grooves of the ratchet mechanism. However, there are cases where the engagement of the engagement claws and engagement grooves is not enough to lock the windscreen. Also, in the windscreen device disclosed in Patent Document 1, the ratchet mechanism is located relatively far from the rotation shaft that rotatably supports the screen bracket. The mechanism that allows the height and tilt angle of the windscreen to be changed (i.e., the hinge mechanism including the rotation shaft) and the mechanism that locks the windscreen (i.e., the ratchet mechanism) are located far away from each other. As a result, windscreen devices tend to become larger.

The present invention has been made in light of these points, and its purpose is to provide a windscreen device that allows the height and tilt angle of the windscreen to be easily changed manually, can lock the windscreen well, and is easy to miniaturize.

The windscreen device disclosed herein is a windscreen device provided for a saddle-type vehicle, and includes a windscreen, a screen support member supporting the windscreen, a fixed member fixed to a vehicle body, and a hinge mechanism rotatably connecting the screen support member to the fixed member. The hinge mechanism includes an arm member provided on the screen support member, a support shaft rotatably supporting the arm member with respect to the fixed member, a slide member attached to the arm member and slidable in a first direction approaching the fixed member and a second direction away from the fixed member, and a pin provided on the slide member and protruding in the first direction. The fixed member has a first opposing surface that faces the slide member when the windscreen is in a first position, and a second opposing surface that faces the slide member when the windscreen is in a second position. A first pin hole and a second pin hole into which the pin can be inserted are formed in the first opposing surface and the second opposing surface of the fixed member, respectively. When changing the position of the windscreen between the first position and the second position, the arm member is configured to rotate around the axis of the support shaft. The support shaft of the hinge mechanism extends in the left-right direction. The fixing member has a left side plate that rotatably supports the support shaft, a right side plate that is disposed to the right of the left side plate and rotatably supports the support shaft, and an upper plate that spans the left side plate and the right side plate and has an upper surface that includes the first opposing surface and the second opposing surface. The first pin hole and the second pin hole are formed in the upper plate. The slide member is attached to the arm member so as to be slidable upward and downward. The pin protrudes downward from the slide member.

According to the above windscreen device, the height and inclination angle of the windscreen can be easily changed manually by sliding the slide member in the second direction to pull the pin out of the pin hole and rotating the arm member relative to the fixed member. Also, the hinge mechanism can be locked by sliding the slide member in the first direction to insert the pin into the pin hole. The position of the windscreen can be locked satisfactorily by the engagement of the pin and the pin hole. Also, the support shaft that rotatably supports the arm member relative to the fixed member, and the pin and pin hole that lock the hinge mechanism are both provided in the hinge mechanism, and are therefore located close to each other. Therefore, the windscreen device can be easily miniaturized. Also, the above-mentioned effects can be obtained with a relatively simple configuration. Also, the occupant can easily lock and release the windscreen by sliding the slide member up and down. The occupant can change the position and inclination angle of the windscreen while remaining aboard the saddle-type vehicle.

The sliding member may have a contact surface that contacts the first opposing surface of the fixed member when the windscreen is in the first position and that contacts the second opposing surface of the fixed member when the windscreen is in the second position.

As a result, when the windscreen is in the first position, the contact surface of the sliding member comes into contact with the first opposing surface of the fixed member, so that the sliding member is stably supported on the fixed member. Since the sliding member can be effectively prevented from shifting out of position, the windscreen can be effectively held in the first position. Similarly, when the windscreen is in the second position, the contact surface of the sliding member comes into contact with the second opposing surface of the fixed member, so that the sliding member is stably supported on the fixed member. Since the sliding member can be effectively prevented from shifting out of position, the windscreen can be effectively held in the second position.

The fixing member may have a groove formed therein that connects the first pin hole and the second pin hole. The depth of the groove may be shallower than the depth of the first pin hole and shallower than the depth of the second pin hole.

As a result, when changing the position of the windscreen, for example, the pin can be moved along the groove from the first pin hole to the second pin hole and inserted into the second pin hole without having to completely remove the pin from the first pin hole. This makes it easy and fast to change the position of the windscreen from the first position to the second position. Similarly, it makes it easy and fast to change the position of the windscreen from the second position to the first position. Furthermore, since the position of the windscreen can be changed while part of the pin remains inserted in the groove, the position of the windscreen can be changed stably.

A corner may be provided between the first and second opposing surfaces of the fixing member.

As a result, the position of the sliding member relative to the fixed member will not change unless the sliding member climbs over a corner of the fixed member. This allows the windscreen to be locked in position even more effectively.

The hinge mechanism may have a biasing member that biases the slide member in the first direction.

As a result, when the pin and pin hole are aligned with each other, the sliding member moves in the first direction due to the biasing force of the biasing member, and the pin is automatically inserted into the pin hole. This makes it easy to lock the windscreen. Also, because the pin is unlikely to come out of the pin hole, the windscreen can be locked well.

The slide member may be made of a convex or concave portion and may have a hook portion on which a person's finger can be hooked.

This allows the pin to be easily removed from the pin hole, for example, by hooking a finger on the hook and sliding the slide member in the second direction. This makes it easier to change the position of the windscreen.

The saddle-type vehicle disclosed herein includes a vehicle body having a body frame with a head pipe, a steering shaft supported on the head pipe so as to be rotatable to the left and right, and a handlebar fixed to the steering shaft and disposed above the head pipe. The saddle-type vehicle includes the windscreen device, at least a portion of which is disposed in front of the handlebar.

The first position of the windscreen may be lower than the second position.The saddle-type vehicle may have a locking member fixed to the vehicle body.The windscreen device may have a first locking portion locked to the locking member and a second locking portion locked to the arm member, and may have a spring that biases the windscreen toward the first position via the arm member and the screen support member.

As a result, in the unlikely event that the pin breaks, the windscreen will be positioned in the first position by the spring. This prevents the windscreen from moving unstably when, for example, the saddle-type vehicle is traveling on an uneven road surface.

The saddle-type vehicle may include a rail member fixed to the vehicle body, in which a slide groove is formed that is curved to be convex toward the front and upward, and a slide bar that is provided on the screen support member and extends to the left and right and slidably engaged with the slide groove.

This makes it easier to change the position of the windscreen, as the rail member and slide bar guide the movement of the windscreen.

The rail member may have a first end portion that divides one end portion of the slide groove and a second end portion that divides the other end portion of the slide groove. The first end portion may be formed to abut against the slide bar when the windscreen is in the first position. The second end portion may be formed to abut against the slide bar when the windscreen is in the second position.

As a result, the windscreen can be easily positioned in a first position by abutting the slide bar against the first end of the rail member. Similarly, the windscreen can be easily positioned in a second position by abutting the slide bar against the second end of the rail member. This makes it easy to change the position of the windscreen.

The present invention provides a windscreen device that allows the height and inclination angle of the windscreen to be easily changed manually, can lock the windscreen well, and is easy to miniaturize.

Hereinafter, an embodiment of a windscreen device and a saddle-type vehicle will be described with reference to the drawings. Figure 1 is a left side view of a motorcycle 1, which is an example of a saddle-type vehicle.

In the following explanation, unless otherwise specified, front, rear, left, right, top, and bottom refer to the front, rear, left, right, top, and bottom as seen by a virtual rider sitting on the seat 17 when the motorcycle 1, with no rider or luggage on board, is stopped in an upright position on a horizontal plane. In the drawings, F, Re, L, R, U, and D represent the front, rear, left, right, top, and bottom, respectively.

The motorcycle 1 includes a body 10, a seat 17 for a rider, a drive source 13 for traveling, a front wheel 6, a rear wheel 8, and a windscreen device 20.

The vehicle body 10 has a body frame 2 (see FIG. 2) having a head pipe 3, a steering shaft 5 supported on the head pipe 3 so as to be rotatable left and right, and a handlebar 11 fixed to the steering shaft 5. The handlebar 11 is disposed above the head pipe 3. A front cover 15 is disposed in front of the head pipe 3. FIG. 2 is a side view of the body frame 2. The body frame 2 has the head pipe 3, a main frame 4 extending rearward from the head pipe 3, and a seat frame 7 extending rearward from the main frame 4. Note that FIG. 1 shows only the head pipe 3 of the body frame 2.

As shown in FIG. 1, the vehicle body 10 has a front fork 12 fixed to the steering shaft 5. The front wheel 6 is supported by the front fork 12. The drive source 13 has an internal combustion engine or an electric motor. The drive source 13 is supported by the vehicle body frame 2. The rear wheel 8 is connected to the drive source 13. The rear wheel 8 is driven by the drive source 13. The seat 17 is supported by the seat frame 7 (see FIG. 2). The seat 17 is positioned above the front wheel 6 and the rear wheel 8.

The windscreen device 20 is a device for blocking wind from the front that occurs when the motorcycle 1 is traveling. At least a portion of the windscreen device 20 is disposed in front of the handlebar 11. Next, the details of the windscreen device 20 will be described.

Figures 3 and 4 are left side views of the windscreen device 20. Figure 5 is a rear view of a portion of the windscreen device 20. Figures 6 and 7 are perspective views of a portion of the windscreen device 20 seen obliquely from the rear. As shown in Figure 7, the windscreen device 20 has a windscreen 21, a screen support member 22 that supports the windscreen 21, left and right fixed members 23 fixed to the vehicle body 10, and a hinge mechanism 24 that rotatably connects the screen support member 22 to the fixed members 23.

The position of the windscreen 21 can be changed by rotating the screen support member 22 relative to the fixed member 23. Note that changing the position of the windscreen 21 means changing the height of the windscreen 21 and/or changing the angle of the windscreen 21 with respect to the horizontal line in a side view of the vehicle (hereinafter simply referred to as the tilt angle). In this embodiment, changing the position of the windscreen 21 means changing both the height and the tilt angle of the windscreen 21. Figures 3 and 6 show the state when the windscreen 21 is in the high position. Figures 4 and 7 show the state when the windscreen 21 is in the low position. The high position is a higher position than the low position. In this embodiment, the tilt angle when the windscreen 21 is in the high position is larger than the tilt angle when it is in the low position. Note that the low position is an example of the first position, and the high position is an example of the second position.

The material of the windscreen 21 is not particularly limited, but may be, for example, a transparent resin material. As shown in FIG. 1, the windscreen 21 extends above the handlebar 11. The screen support member 22 is fixed to the lower part of the windscreen 21.

The fixing member 23 only needs to be fixed to the vehicle body 10, and is fixed to the head pipe 3 of the vehicle frame 2 via a bracket (not shown). The material of the fixing member 23 is not particularly limited, and may be a metal such as iron, or may be a resin material. FIG. 8 is a perspective view of the fixing member 23. The shape of the fixing member 23 is not particularly limited. In this embodiment, the fixing member 23 has a left side plate 23L, a right side plate 23R (see FIG. 6), and an upper plate 23U. The right side plate 23R is disposed to the right of the left side plate 23L. The upper plate 23U is bridged between the left side plate 23L and the right side plate 23R. The upper plate 23U has a first opposing surface 29a and a second opposing surface 29b that face the slide member 27 described later. The second opposing surface 29b is located rearward and above the first opposing surface 29a. The first opposing surface 29a and the second opposing surface 29b are not parallel to each other. A corner portion 29c is provided between the first opposing surface 29a and the second opposing surface 29b.

Through holes 32 extending left and right are formed in the left and right plates 23L and 23R. The upper plate 23U is formed with a first pin hole 30a and a second pin hole 30b. The first pin hole 30a is formed in the first opposing surface 29a. The first pin hole 30a is recessed from the first opposing surface 29a. The second pin hole 30b is formed in the second opposing surface 29b. The second pin hole 30b is recessed from the second opposing surface 29b. The first pin hole 30a extends in a direction perpendicular to the first opposing surface 29a, and the second pin hole 30b extends in a direction perpendicular to the second opposing surface 29b. In addition, a groove 34 connecting the first pin hole 30a and the second pin hole 30b is formed in the fixing member 23. The groove 34 extends rearward and upward. The groove 34 is formed across the corner 29c. The depth of the groove 34 is shallower than the depth of the first pin 30a and shallower than the depth of the second pin hole 30b.

As shown in FIG. 6, the hinge mechanism 24 has an arm member 25 provided on the screen support member 22, a support shaft 26 that rotatably supports the arm member 25 with respect to the fixed member 23, and a slide member 27 that is slidably attached to the arm member 25. The arm member 25 has a central arm 25a fixed to the screen support member 22, left and right rear arms 25b that extend rearward from the central arm 25a, and a lower arm 25c that extends downward from the rear arm 25b. The support shaft 26 extends in the left-right direction. The support shaft 26 is inserted into a through hole 32 in the fixed member 23.

The slide member 27 is slidably attached to the lower arm 25c. The slide member 27 is slidable in a first direction D1, which is a direction toward the fixed member 23, and in a second direction D2, which is a direction away from the fixed member 23. Here, the first direction D1 is downward, and the second direction D2 is upward. The movement of the slide member 27 in the second direction D2 is performed by the occupant. The slide member 27 has a hook portion 27a on which the occupant's finger is hooked. The hook portion 27a is formed, for example, by a convex portion or a concave portion. The slide member 27 also has a contact surface 27b that contacts the fixed member 23. The contact surface 27b of the slide member 27 contacts the first opposing surface 29a or the second opposing surface 29b of the fixed member 23.

Figure 9 is a cross-sectional view of line IX-IX in Figure 6. As shown in Figure 9, the slide member 27 is provided with a pin 28. The pin 28 protrudes from the slide member 27 in the first direction D1. The pin 28 is configured to be insertable into the first pin hole 30a and the second pin hole 30b. By moving the slide member 27 in the first direction D1, the pin 28 can be inserted into the first pin hole 30a or the second pin hole 30b. When the pin 28 is inserted into the first pin hole 30a or the second pin hole 30b, the rotation of the arm member 25 relative to the fixed member 23 is restricted. This allows the hinge mechanism 24 to be locked. By moving the slide member 27 in the second direction D2, the pin 28 can be pulled out of the first pin hole 30a or the second pin hole 30b. This allows the hinge mechanism 24 to be unlocked. When the pin 28 is removed from the first pin hole 30a and the second pin hole 30b, the arm member 25 can be rotated relative to the fixed member 23.

As described above, the fixing member 23 has a groove 34 that connects the first pin hole 30a and the second pin hole 30b. By moving the pin 28 in the groove 34, the pin 28 can be moved between the first pin hole 30a and the second pin hole 30b. The first pin hole 30a includes a back portion 30aa that is deeper than the groove 34 and a portion 30ab that is shallower than the back portion 30aa. The second pin hole 30b includes a back portion 30ba that is deeper than the groove 34 and a portion 30bb that is shallower than the back portion 30ba. The pin 28 can be moved between the first pin hole 30a and the second pin hole 30b by simply pulling it out from the back portion 30aa of the first pin hole 30a or the back portion 30ba of the second pin hole 30b without pulling it out from the entire first pin hole 30a or the entire second pin hole 30b. Therefore, it is possible to rotate the arm member 25 relative to the fixed member 23 without pulling the pin 28 out entirely from the first pin hole 30a or the second pin hole 30b.

As shown in FIG. 9, the hinge mechanism 24 has a spring 33 that biases the slide member 27 in the first direction D1. Here, the spring 33 is configured by a coil spring. However, the form of the spring 33 is not particularly limited. Also, the spring 33 is an example of a biasing member, but the biasing member is not limited to the spring 33. When the occupant moves the slide member 27 in the second direction D2 against the biasing force of the spring 33, as shown in FIG. 10, the pin 28 is pulled out from the innermost portion 30ba of the second pin hole 30b or the innermost portion 30aa of the first pin hole 30a. When the occupant releases the slide member 27, the biasing force of the spring 33 moves the slide member 27 in the first direction D1, and the pin 28 is inserted into the innermost portion 30ba of the second pin hole 30b or the innermost portion 30aa of the first pin hole 30a (see FIG. 9).

Figures 11 and 12 are enlarged perspective views of the hinge mechanism 24 when the windscreen 21 is in the low position. Figure 11 is a view of the pin 28 inserted into the first pin hole 30a. Figure 12 is a view of the pin 28 pulled out of the first pin hole 30a. As shown in Figure 11, when the windscreen 21 is in the low position, the contact surface 27b (see Figure 9) of the sliding member 27 contacts the first opposing surface 29a of the fixed member 23. The sliding member 27 is supported by the first opposing surface 29a of the fixed member 23.

Figures 13 and 14 are enlarged perspective views of the hinge mechanism 24 when the windscreen 21 is in the high position. Figure 13 is a view before the pin 28 is inserted into the second pin hole 30b. Figure 14 is a view when the pin 28 is inserted into the second pin hole 30b. As shown in Figure 14, when the windscreen 21 is in the high position, the contact surface 27b of the sliding member 27 contacts the second opposing surface 29b of the fixed member 23. The sliding member 27 is supported by the second opposing surface 29b of the fixed member 23.

When changing the position of the windscreen 21, the arm member 25 rotates around the axis 26c of the support shaft 26 (see Figures 6 and 7). The screen support member 22 is fixed to the arm member 25. Therefore, when changing the position of the windscreen 21, the screen support member 22 rotates around the axis 26c of the support shaft 26. As shown in Figures 6 and 7, the motorcycle 1 according to this embodiment is provided with a rail member 41 that guides the rotation of the screen support member 22.

The rail member 41 is fixed to the vehicle body 10. Here, the rail member 41 is fixed to the head pipe 3 of the vehicle body frame 2 via a bracket (not shown). A slide groove 40 is formed in the rail member 41, which is curved so as to be convex toward the front and upward (see FIG. 3). The screen support member 22 is provided with a slide bar 42 that is slidably engaged with the slide groove 40. The slide bar 42 extends in the left-right direction. As the slide bar 42 moves upward or downward along the slide groove 40, the screen support member 22 is guided upward or downward by the rail member 41.

The rail member 41 has a first end 41a that divides one end of the slide groove 40 and a second end 41b that divides the other end. The slide bar 42 is movable between the first end 41a and the second end 41b in the slide groove 40. As shown in FIG. 7, the first end 41a is formed to abut against the slide bar 42 when the windscreen 21 is in the low position. When the screen support member 22 rotates downward around the axis 26c of the support shaft 26, the slide bar 42 abuts against the first end 41a, thereby restricting the downward movement of the screen support member 22. As a result, the windscreen 21 is positioned in the low position. The second end 41b is formed to abut against the slide bar 42 when the windscreen 21 is in the high position. When the screen support member 22 rotates upward around the axis 26c of the support shaft 26, the slide bar 42 abuts against the second end 41b, restricting the upward movement of the screen support member 22. This positions the windscreen 21 in the high position.

As shown in FIG. 5, the motorcycle 1 is provided with a spring 35 that biases the screen support member 22 downward. A locking member 34 is fixed to the vehicle body 10. The locking member 34 is fixed to the head pipe 3, for example, via a bracket (not shown). Here, the spring 35 is formed of a torsion coil spring. The spring 35 has a first locking portion 35a that is locked to the locking member 34 and a second locking portion 35b that is locked to the central arm 25a of the arm member 25. The spring 35 biases the arm member 25 downward. The arm member 25 is fixed to the screen support member 22, and the windscreen 1 is supported by the screen support member 22. Therefore, the spring 35 biases the windscreen 1 toward the low position via the arm member 25 and the screen support member 22.

The above is the configuration of the windscreen device 20. Next, we will explain how to change the position of the windscreen 21.

The position of the windscreen 21 is changed manually. The position of the windscreen 21 is changed, for example, by the occupant. When moving the windscreen 21 from the low position to the high position, the occupant first pushes up the left and right slide members 27 in the second direction D2. At this time, the slide members 27 can be easily moved by hooking their fingers on the hooks 27a. As shown in FIG. 12, when the slide members 27 move in the second direction D2, the contact surface 27b of the slide members 27 moves away from the first opposing surface 29a of the fixed member 23, and the pin 28 is pulled out of the first pin hole 30a. This releases the lock on the hinge mechanism 24. As described above, the fixed member 23 has a groove 34 that connects the first pin hole 30a and the second pin hole 30b. The hinge mechanism 24 can be released by simply pulling out the pin 28 from the innermost portion 30aa of the first pin hole 30a.

Next, the occupant rotates the arm member 25 upward around the axis 26c of the support shaft 26. At this time, the slide bar 42 moves from the first end 41a to the second end 41b along the slide groove 40 of the rail member 41. The rail member 41 guides the movement of the arm member 25, the screen support member 22, and the windscreen 21. Therefore, the windscreen 21 moves smoothly. When the windscreen 21 reaches the high position, the slide bar 42 abuts against the second end 41b, and further rotation of the arm member 25 is restricted. At this time, as shown in FIG. 13, the pin 28 is positioned directly above the second pin hole 30b.

When the occupant releases the slide member 27, the force of the spring 33 (see FIG. 9) causes the slide member 27 to move in the first direction D1. As a result, the pin 28 is inserted into the second pin hole 30b (see FIG. 14). This restricts the rotation of the arm member 25 and locks the hinge mechanism 24. The windscreen 21 is locked in the high position.

In this way, the position of the windscreen 21 can be changed from the low position to the high position without using a tool such as a screwdriver. In addition, the operation can be performed while the occupant remains seated in the seat 17.

The position of the windscreen 21 can be changed from the high position to the low position in the same way. In other words, by performing the reverse operation of moving the windscreen 21 from the low position to the high position, the windscreen 21 can be moved manually from the high position to the low position without using tools.

This embodiment can provide a variety of effects. Next, we will explain the various effects provided by this embodiment.

According to the windscreen device 20 of this embodiment, the height and inclination angle of the windscreen 21 can be easily changed manually by sliding the slide member 27 in the second direction D2 to pull out the pin 28 from the first pin hole 30a or the second pin hole 30b and rotating the arm member 25 relative to the fixed member 23. In addition, the hinge mechanism 24 can be locked by sliding the slide member 27 in the first direction D1 to insert the pin 28 into the first pin hole 30a or the second pin hole 30b. The windscreen 21 can be locked well by the engagement of the pin 28 with the first pin hole 30a or the second pin hole 30b. In addition, the support shaft 26 that rotatably supports the arm member 25 relative to the fixed member 23, and the pin 28, the first pin hole 30a, and the second pin hole 30b that lock the hinge mechanism 24 are all provided in the hinge mechanism 24 and are therefore located close to each other. This makes it easy to reduce the size of the windscreen device 20. As described above, the windscreen device 20 according to this embodiment allows the height and inclination angle of the windscreen 21 to be easily changed manually, the windscreen 21 can be locked well, and it is easy to reduce the size.

According to this embodiment, when the windscreen 21 is in the low position, the contact surface 27b of the slide member 27 comes into contact with the first opposing surface 29a of the fixed member 23, so that the slide member 27 is stably supported on the fixed member 23. Since the positional deviation of the slide member 27 can be effectively prevented, the windscreen 21 can be effectively held in the low position. Similarly, when the windscreen 21 is in the high position, the contact surface 27b of the slide member 27 comes into contact with the second opposing surface 29b of the fixed member 23, so that the slide member 27 is stably supported on the fixed member 23. Since the positional deviation of the slide member 27 can be effectively prevented, the windscreen 21 can be effectively held in the high position.

According to this embodiment, a groove 34 that connects the first pin hole 30a and the second pin hole 30b is formed in the fixing member 23. For example, when changing the position of the windscreen 21 from the low position to the high position, the pin 28 does not need to be completely pulled out from the first pin hole 30a, but can be moved from the first pin hole 30a to the second pin hole 30b along the groove 34 by simply pulling it out from the inner part 30aa of the first pin hole 30a, and can be inserted into the second pin hole 30b. Therefore, the position of the windscreen 21 can be easily and quickly changed from the low position to the high position. Similarly, the position of the windscreen 21 can be easily and quickly changed from the high position to the low position. In addition, when changing the position of the windscreen 21, a part of the pin 28 is inserted into the groove 34, so that the pin 28 prevents the arm member 25 from shaking left and right. Since the arm member 25 is not easily shaken left and right, the windscreen 21 can be moved stably.

According to this embodiment, a corner 29c is provided between the first opposing surface 29a and the second opposing surface 29b of the fixed member 23. Even if the pin 28 is damaged, the position of the slide member 27 relative to the fixed member 23 will not change unless the slide member 27 climbs over the corner 29c of the fixed member 23. Therefore, the position of the windscreen 21 can be maintained satisfactorily.

According to this embodiment, the hinge mechanism 24 has a spring 33 that biases the slide member 27 in the first direction D1. When the pin 28 and the first pin hole 30a are in position with respect to each other, and when the pin 28 and the second pin hole 30b are in position with respect to each other, the slide member 27 moves in the first direction D1 due to the biasing force of the spring 33. Therefore, the pin 28 is automatically inserted into the first pin hole 30a or the second pin hole 30b. Therefore, the operation of locking the hinge mechanism 24 is easy, and the operation of locking the windscreen 21 in the low position or the high position is easy. In addition, since the pin 28 is unlikely to come out of the first pin hole 30a or the second pin hole 30b, the windscreen 21 can be locked well.

According to this embodiment, the slide member 27 has a hook portion 27a on which a person's finger can be hooked. By hooking a finger on the hook portion 27a and sliding the slide member 27 in the second direction D2, the pin 28 can be easily pulled out of the first pin hole 30a or the second pin hole 30b. This makes it easy to change the position of the windscreen 21.

According to this embodiment, the windscreen device 20 has a spring 35 that biases the windscreen 21 toward the low position via the arm member 25 and the screen support member 22. Therefore, if the hinge mechanism 24 cannot be locked due to damage to the pin 28, the spring 35 positions the windscreen 21 in the low position. This makes it possible to prevent the windscreen 21 from moving unstably when the motorcycle 1 is traveling on an uneven road surface, for example.

According to this embodiment, the motorcycle 1 includes a rail member 41 fixed to the vehicle body 10 and a slide bar 42 provided on the screen support member 2. The slide bar 42 slidably engages with the slide groove 40 of the rail member 41. The rail member 41 and the slide bar 42 guide the movement of the windscreen 21, making it easy to change the position of the windscreen 21.

The rail member 41 has a first end 41a that divides one end of the slide groove 40, and a second end 41b that divides the other end of the slide groove 40. By abutting the slide bar 42 against the first end 41a, the windscreen 21 can be easily positioned in the low position. Similarly, by abutting the slide bar 42 against the second end 41b, the windscreen 21 can be easily positioned in the high position. This makes it easy to change the position of the windscreen 21.

One embodiment has been described above. However, the above embodiment is merely an example, and various other embodiments are possible.

The shape of the fixing member 23 is not particularly limited. There may be no corner 29c between the first opposing surface 29a and the second opposing surface 29b of the fixing member 23. The first opposing surface 29a and the second opposing surface 29b may be flush with each other.

The groove 12 connecting the first pin hole 30a and the second pin hole 30b may not be required.

The spring 33 that biases the slide member 27 in the first direction D1 may be omitted. The spring 33 may be omitted, and a locking mechanism may be provided that locks the slide member 27 when the pin 28 is inserted into the first pin hole 30a or the second pin hole 30b.

The slide member 27 does not have to have a hook portion 27a.

The spring 35 that biases the windscreen 21 toward the low position may not be required.

The rail member 41 and the slide bar 42 may be omitted. The first end 40a or the second end 40b of the rail member 41 may be omitted.

A saddle-type vehicle is a vehicle on which a rider sits astride. The saddle-type vehicle is not limited to the motorcycle 1. The saddle-type vehicle may be, for example, a three-wheeled motor vehicle, an ATV (All Terrain vehicle), or a snowmobile.
