[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a side stand structure that can improve the appearance of the side stand, reduce its weight, and increase the strength of the side stand. [Means for solving the problem]

[0006] As a means for solving the above-mentioned problem, a first aspect of the present invention comprises a stand member (21) pivotally supported on one of the left and right sides of a vehicle body and rotatably provided between an upright position and a storage position, the stand member (21) comprises a base (22) rotatably connected to the vehicle body, a ground contact portion (24) that comes into contact with the ground when the stand member (21) is in the upright position, and a plate-shaped connection portion (23) that connects the base (22) and the ground contact portion (24), the plate thickness direction (F3) of the connection portion (23) being arranged in the vehicle width direction when the stand member (21) is in the storage position, and a side edge portion of the connection portion (23) along the extension direction (F1) between the base (22) and the ground contact portion (24) of the stand member (21) being in the storage position. an upper edge portion (23c) located on the upper side in the vertical direction of the vehicle when the stand member (21) is in the stored position is provided with a raised portion (26) that raised inward in the vehicle width direction in the plate thickness direction (F3), and a protruding portion (27) that protrudes outward in the vehicle width direction in the plate thickness direction (F3) and serves as an operating portion when rotating the stand member (21), the raised portion (26) and the protruding portion (27) respectively having a raised upper surface portion (26a) and a protruding upper surface portion (27a) that face upward in the vertical direction of the vehicle when the stand member (21) is in the stored position, and the raised upper surface portion (26a) and the protruding upper surface portion (27a) are formed flat and continuous with each other. According to this configuration, the stand member having a plate-shaped connecting portion (arm portion) can reduce the weight of the stand member, and improve the appearance by using a wide surface on one side of the connecting portion in the plate thickness direction as the external appearance surface. The raised portion (thick portion), which is the reinforcing portion of the connecting portion, and the protruding portion, which is the rotation operation portion of the stand member, are connected in a flush manner, so that the input during stand operation can be effectively received by distributing it in the extension direction (length direction) of the stand member.

[0007] A second aspect of the present invention is characterized in that, in the above-mentioned first aspect, the connection portion (23) has an outer surface portion (23a) facing outward in the vehicle width direction and an inner surface portion (23b) facing inward in the vehicle width direction, and the inner surface portion (23b) is located below the raised portion (26) when the stand member (21) is in the storage position. According to this configuration, when the stand member is in the storage position, the inner surface of the connection portion is positioned below the raised portion, making the inner surface side of the connection portion less visible and improving the appearance.

[0008] A third aspect of the present invention is characterized in that, in the first or second aspect described above, the raised portion (26) is located at the vehicle widthwise outer end of the connection portion (23) when the stand member (21) is in the upright position. According to this configuration, the raised portion formed on one side edge of the plate-shaped connection portion is positioned at the outer end in the widthwise direction of the vehicle when the stand is upright, thereby making the plate-shaped connection portion appear thick when the stand is upright while making the inner side of the connection portion less visible, thereby improving the appearance.

[0009] A fourth aspect of the present invention is characterized in that, in the above-mentioned second aspect, a vehicle body cover member (11eL) is provided which covers the periphery of the stand support portion (31) on the vehicle body, the vehicle body cover member (11eL) is provided with a storage recess (34) for storing the stand member (21) in the storage position, and the inside of the storage recess (34) is provided with a protruding portion (36) which protrudes toward the inner surface portion (23b) of the stand member (21) in the storage position. According to this configuration, by providing a protruding portion that protrudes toward the inner surface of the stand member in the storage recess that stores the stand member in the storage position, the stand member and the vehicle body cover member are closer together in the stand storage state, and the gap between the stand member and the vehicle body cover member can be reduced to improve the appearance. Although the storage recess is concave when viewed from outside the vehicle, even if a structure such as a vehicle frame is present on the rear side of the storage recess, the protruding portion covers the structure, hiding it, improving the appearance in the stand upright state, and ensuring a gap between the structure and the vehicle body cover member to suppress interference between vehicle parts.

[0010] A fifth aspect of the present invention is characterized in that, in the above-mentioned fourth aspect, at least the end (36c) of the protrusion (36) on the inner surface portion (23b) side is adjacent to a virtual area obtained by circumferentially extending the rotation area (R1) of the stand member (21), and the end (36c) of the protrusion (36) is located lower than the connection portion (23) of the stand member (21) in the storage position in the vertical direction of the vehicle. With this configuration, the end (top) of the protrusion on the inner surface of the stand is close to the extension of the rotation area of ​​the stand member, while the top of the protrusion is positioned lower than the connection portion, making it possible to position the raised portion above the top of the protrusion, and efficiently secure space to avoid the raised portion and store the stand member. Effect of the Invention

[0011] According to the present invention, it is possible to provide a side stand structure that can improve the appearance of the side stand, reduce its weight, and increase the strength of the side stand. [Brief description of the drawings]

[0014] <Entire vehicle> 1 shows a scooter-type motorcycle 1 as an example of a saddle-ride type vehicle of an embodiment. The motorcycle 1 has a front wheel 3 which is a steering wheel, and a rear wheel 4 which is a driving wheel. The front wheel 3 is supported by a pair of left and right front forks 3a, and can be turned (steered) by a bar handle 2. The rear wheel 4 is supported by a swing-type power unit 8, and can be driven by the power unit 8.

[0015] Steering system components including the handlebars 2, the front forks 3a, and the front wheel 3 are supported rotatably (steerably) on a head pipe 16a at the front end of a body frame 16. A front portion of the power unit 8 is supported on a lower portion of the body frame 16 so as to be vertically swingable. The body frame 16 includes a head pipe 16a, a down frame 16b extending downward and rearward from the head pipe 16a, a lower frame 16c extending rearward from a lower portion of the down frame 16b, and a rear frame 16d extending rearward and upward from the rear of the lower frame 16c.

[0016] A floor step 6 on which the driver places his / her feet is provided between the front wheel 3 and the rear wheel 4. A front body 14 is provided in front of the floor step 6. A rear body 15 is provided behind the floor step 6. A space K1 above the floor step 6 between the front body 14 and the rear body 15 is used as a straddling space K1 when the driver straddles the vehicle body. A handlebar 2 is disposed above the front body 14. A seat 5 on which a passenger sits is supported above the rear body 15. A collapsible side stand device 20 capable of supporting the vehicle body in an upright position with the body tilted to the left is provided on the lower left side of the floor step 6.

[0017] The power unit 8 includes, for example, an electric motor M as a drive source, and a transmission mechanism (for example, a gear-type reduction gear) T that transmits the drive force generated by the electric motor M to the rear wheel 4. The electric motor M and the transmission mechanism T are provided on a left arm portion of the power unit 8 configured as a swing arm. The power unit 8 may have various configurations, and may include, for example, an internal combustion engine as a drive source. A driving battery BT that stores electricity for driving is mounted below the seat 5.

[0018] The periphery of the body frame 16 of the motorcycle 1 is covered with a body cover 11. The body cover 11 includes a front body cover 11a that forms the outer surface of the front body 14, a rear body cover 11b that forms the outer surface of the rear body 15, and a floor cover 11c that forms the floor step 6. The floor cover 11c includes a step board 11d that forms a footrest surface (floor upper surface), left and right floor side covers 11e that extend downward from the outer side edges of the step board 11d in the vehicle width direction, and an undercover 11f that covers the lower surface of the floor step 6.

[0019] <Side stand device 20> Fig. 2 is a left side view of the side stand device 20 in a retracted state, Fig. 3 is a left side view of the side stand device 20 in a raised state, Fig. 4 is a sectional view taken along the line IV-IV in Fig. 2, and Fig. 5 is a sectional view taken along the line VV in Fig. 3. The floor side cover 11e on the left side of the vehicle body is indicated by the reference symbol 11eL. As shown in Figures 2 to 5, the side stand device 20 can be rotated between a stored position (folded position, see Figures 2 and 4) in which the tip side (ground contact part 24 side) of the stand member (stand bar) 21 is flipped up behind the rotating shaft 25, and an upright position (use position, see Figures 3 and 5) in which the tip side of the stand member 21 is extended below the rotating shaft 25. The states in Figures 2 and 4 are called the stand stored state, and the states in Figures 3 and 5 are called the stand upright state. Line C1 in the figures indicates the central axis of the rotating shaft 25.

[0020] 3 and 4, the side stand device 20 is attached to the left side (left lower frame 16cL) of the pair of left and right lower frames 16c. The side stand device 20 includes a stand bracket 31 fixed to the left lower frame 16cL, and a stand member 21 rotatably supported by the stand bracket 31.

[0021] 6 is a side view of the stand member 21 as viewed from the axial direction of the rotation shaft 25, and FIG. 7 is a cross-sectional view taken along line VII-VII in FIG. The stand member 21 will be described below, and unless otherwise specified, the stand member 21 in the stored stand state will be described. 2 to 7, the stand member 21 extends linearly from the base end side (the stand bracket 31 side) to the tip end side (the ground contact part 24 side). The stand member 21 includes a pivot part (base part) 22 rotatably connected to the vehicle body side (the stand bracket 31), a ground contact part 24 spaced from the pivot part 22 toward the tip end side and capable of contacting the ground in the stand upright state, and a plate-shaped connecting part (arm part) 23 extending linearly between the pivot part 22 and the ground contact part 24 and connecting the pivot part 22 and the ground contact part 24. The stand member 21 is integrally formed as a forged part made of, for example, an aluminum alloy.

[0022] The pivot portion 22 is bifurcated so as to sandwich the stand connecting portion 32 of the flat stand bracket 31 in the plate thickness direction. The pivot portion 22 includes a pair of plate portions 22a and 22b. The plate portions 22a and 22b are provided parallel to each other with a gap in the plate thickness direction of the stand connecting portion 32. A groove portion 22c is formed between the plate portions 22a and 22b, into which the stand connecting portion 32 is inserted so as to be rotatable relative to each other. A shaft insertion hole through which the rotation shaft 25 is inserted is formed coaxially in both plate portions 22a and 22b. A stand switch (rotary switch) 25d for detecting that the stand is in an upright state is coaxially arranged on the outer side of the plate portion 22a on the outer side in the vehicle width direction.

[0023] The stand member 21 is rotatably connected (supported) to the stand bracket 31 via the pivot shaft 25 by inserting the stand connecting portion 32 of the stand bracket 31 into the groove portion 22c of the pivot portion 22 and attaching a pivot shaft 25 that passes through the pivot portion 22 and the stand connecting portion 32.

[0024] The pivot shaft 25 is inclined upward so as to be positioned higher toward the outer side in the vehicle width direction. As a result, when the stand member 21 is rotated from the stand stored state to the stand upright state, the stand member 21 extends so as to overhang outward in the vehicle width direction. As a result, the ground contact portion 24 is disposed on the outer side in the vehicle width direction, making it easier to support the vehicle body in an upright state. Also, when the stand member 21 is in the stand stored state, the overhang of the stand member 21 toward the outer side in the vehicle width direction is suppressed. As a result, the stand member 21 is less likely to touch the ground when the vehicle body is banked. The pivot shaft 25 may have an inclination that is positioned forward or rearward toward the outer side in the vehicle width direction.

[0025] In the stand-stored state, the connection part 23 is disposed so that its plate thickness direction (arrow in the figure) faces the vehicle width direction. The plate thickness direction of the connection part 23 is inclined with respect to the vehicle width direction so that the outer side in the vehicle width direction is located higher in the vehicle vertical direction. The arrow F1 in Fig. 5 indicates the extension direction between the pivot part 22 and the ground contact part 24 in the connection part 23. The arrow F2 in Fig. 4 indicates the plate width direction spanning the upper and lower edges in the cross section of the connection part 23, and the arrow F3 indicates the plate thickness direction at the center of the plate width in the cross section of the connection part 23.

[0026] Of the pair of side edges along the extension direction of the connection part 23, the side edge located on the upper side in the vertical direction of the vehicle (and on the outer side in the vehicle width direction) in the stand-stored state is called the upper edge part 23c, and the side edge located on the lower side in the vertical direction of the vehicle (and on the inner side in the vehicle width direction) in the stand-stored state is called the lower edge part 23d. The upper edge part 23c extends substantially horizontally in the stand-stored state except for the base end side (front end side). The base end side (front end side) of the upper edge part 23c is cut out with a gentle incline so that the plate width of the connection part 23 decreases toward the base end side. The base end side (front end side) of the upper edge part 23c is connected to the pivot part 22 after narrowing the plate width. The lower edge part 23d extends substantially horizontally overall in the stand-stored state, and the base end side (front end side) is directly connected to the pivot part 22.

[0027] 4 and 7, in the stand-stored state, a raised portion 26 is formed on the inside of the upper edge 23c of the connection portion 23 in the vehicle width direction, which is raised in the plate thickness direction toward the inside of the vehicle width direction. The raised portion 26 is a tapered triangular shape in a cross-sectional view and protrudes inward in the vehicle width direction, making the upper edge 23c of the connection portion 23 thicker in the plate thickness direction. The raised portion 26 forms a substantially horizontal raised upper surface portion 26a facing upward in the vehicle up-down direction in the stand-stored state. Furthermore, the raised portion 26 forms an apex 26b located at the end on the inside of the vehicle width direction in the stand-stored state, and a raised lower surface portion 26c extending diagonally downward and outward in the vehicle width direction from the apex 26b.

[0028] A locking hook 29 for locking one end (rear end) of a stand spring (tension coil spring) SP is provided at an intermediate portion (not limited to the central portion) in the length direction (extension direction) of the connection portion 23 of the stand member 21. The locking hook 29 is formed integrally with the connection portion 23, for example (it may be welded).

[0029] A protruding portion (footrest) 27 is provided on the tip side of the connecting portion 23, which protrudes outward in the vehicle width direction together with the grounding portion 24 in the stand stored state and enables the user to rotate the stand member 21 with his / her foot. The protruding portion 27 is formed integrally with the connecting portion 23 and the grounding portion 24, for example (it may be welded). The protruding portion 27 will be described in detail later.

[0030] The connecting portion 23 has an outer surface portion 23a facing outward in the vehicle width direction and an inner surface portion 23b facing inward in the vehicle width direction. In a cross section perpendicular to the extension direction, the connecting portion 23 has a curved cross-sectional shape that is convex toward the outside in the vehicle width direction. The concave inner surface portion 23b is located below the raised portion 26 in the stand-stored state. The upper portion of the inner surface portion 23b rises with a larger curvature toward the raised lower surface portion 26c of the raised portion 26 and merges with it. The upper portion of the inner surface portion 23b and the raised lower surface portion 26c are arranged to form an obtuse angle in cross-sectional view. The upper portion of the outer surface portion 23a and the raised upper surface portion 26a are arranged to form an acute angle in cross-sectional view.

[0031] In the stand-stored state, the concave inner surface 23b is hidden from above by the raised portion 26. As a result, even if a user looks down on the stand periphery from above in the stand-stored state, the concave shape (hollowed-out shape) of the connection portion 23 is not visible. In the stand-stored state, the connection portion 23 is curved so as to fit along the cover outer surface 11e1 of the left floor side cover 11eL, and forms an appearance integrated with the left floor side cover 11eL. The connection portion 23 is not necessarily limited to a curved plate shape, and may be a flat plate shape, and may take an appropriate shape depending on the surrounding shape.

[0032] When the stand member 21 rotates from the stored position to the upright position, the upper edge 23c of the connection part 23 moves to the end of the connection part 23 on the outer side in the vehicle width direction. That is, the raised part 26 is located at the end of the connection part 23 on the outer side in the vehicle width direction in the upright state of the stand, and the raised upper surface part 26a faces outward in the vehicle width direction. In the upright state of the stand, the outer surface part 23a of the connection part 23 faces outward and forward in the vehicle width direction in front of the connection part 23. In the upright state of the stand, the concave inner surface part 23b is hidden on the inner side in the vehicle width direction. As a result, in the upright state of the stand, the hollowed-out shape of the connection part 23 is not visible, and the raised upper surface part 26a creates an appearance that the thickness of the plate-shaped connection part 23 is increased.

[0033] 6 and 7, grounding portion 24 forms a grounding surface 24a larger than the cross-sectional shape of connecting portion 23 when viewed from the extension direction of connecting portion 23. Grounding portion 24 extends outward in the vehicle width direction in the plate thickness direction relative to the cross-sectional shape of connecting portion 23 when viewed from the extension direction of connecting portion 23, and also partially protrudes downward in the axial direction of pivot shaft 25 and inward in the vehicle width direction.

[0034] A protrusion 27 is formed at a portion of the upper edge 23c of the connecting portion 23 on the ground contact portion 24 side in the extension direction (a portion adjacent to the ground contact portion 24), which protrudes outward in the vehicle width direction in the plate thickness direction of the ground contact portion 24 and serves as an operating portion when the user rotates the stand member 21. The protrusion 27 has an end portion on the ground contact portion 24 side connected to the extension portion 24b of the ground contact portion 24 and is integrated with the end portion. The ground contact portion 24 extends outward in the vehicle width direction in accordance with the protrusion 27. The ground contact portion 24 and the protrusion 27 have the same protrusion amount (extension amount) from the rear of the connecting portion 23 outward in the vehicle width direction. The extension portion 24b of the ground contact portion 24 extends at a slight incline toward the base end side, and extends the ground contact surface 24a outward in the vehicle width direction.

[0035] 2 to 7, the protruding portion 27 is formed so as to be parallel to the raised upper surface portion 26a and protrudes outward in the vehicle width direction. The protruding portion 27 (and the extended portion 24b of the grounding portion 24) protrudes outward in the vehicle width direction from the cover outer surface (virtual surface) 11e1 of the left floor side cover 11eL, making it easy for a user to place his / her foot on it. The protruding portion 27 is in the shape of a substantially horizontal plate and protrudes outward in the vehicle width direction, so that it is unlikely to disturb the flow of the running wind. A concave curved surface portion 28 is formed between the rear portion of the outer surface portion 23a of the grounding portion 24, the lower surface portion 27b of the protruding portion 27, and the front surface portion 24c of the extended portion 24b of the grounding portion 24, when viewed from the outside in the vehicle width direction, smoothing the change in the cross-sectional shape of the stand member 21. The protruding portion 27 is inclined so that the front edge portion 27c is positioned rearward as it approaches the outside in the vehicle width direction so that the width (front-rear width) in the vehicle front-rear direction narrows as it approaches the outside in the vehicle width direction. The protruding portion 27 is formed in a generally swept-back wing shape when viewed from above. The tip of the protruding portion 27 is formed with a tip bent portion 27d that is bent upward, making it easier for the user to place his / her foot on it.

[0036] In the stand arrangement portion of the left floor side cover 11eL, the cover outer surface 11e1 is cut out to form a storage recess 34 described later. Therefore, the cover outer surface 11e1 of the stand arrangement portion is a virtual surface, but is formed continuously with the surrounding cover outer surfaces 11e1. For example, the cover outer surface 11e1 of the stand arrangement portion is formed symmetrically with the cover outer surface 11e1 of the right floor side cover 11e.

[0037] The protruding portion 27 forms a protruding upper surface portion 27a that faces upward in the vehicle vertical direction when the stand member 21 is in the storage position. The protruding upper surface portion 27a is formed to be continuous with the raised upper surface portion 26a in a flat shape (in the embodiment, in a flush shape). The protruding upper surface portion 27a and the raised upper surface portion 26a are continuous with each other in a flat shape (in a flush shape) without having a step or the like between them. The protruding upper surface portion 27a and the raised upper surface portion 26a may have a gentle curve to the extent that stress concentration does not occur.

[0038] 3 and 5, the stand bracket 31 is formed of a steel plate having a thickness equal to that of each of the plate portions 22a, 22b of the pivot portion 22 and is fixed to the left lower frame 16cL by welding or bolting. The stand bracket 31 forms a stand connecting portion 32 that is rotatably inserted into the groove portion 22c of the pivot portion 22. The stand connecting portion 32 is formed with a shaft insertion hole through which the shaft portion of the rotating shaft 25 is inserted. The shaft insertion hole is arranged coaxially with the shaft insertion hole provided in the pair of plate portions 22a, 22b of the pivot portion 22 when the stand connecting portion 32 is inserted into the groove portion 22c of the pivot portion 22.

[0039] Stoppers 32a1 and 32a2 that determine the rotational positions of the stand member 21 in the stand stored state and the stand erected state are formed on the outer periphery of the stand connecting portion 32. Stopper abutment surfaces 22d1 and 22d2 that abut against the stoppers 32a1 and 32a2, respectively, are formed on the pivot portion 22 of the stand member 21.

[0040] The rotating shaft 25 has a so-called stepped bolt 25a as a shaft body. The stepped bolt 25a is inserted and removed from the outside in the vehicle width direction into each insertion hole of the pivot part 22 and the stand connecting part 32. The stepped bolt 25a has a head part located on the outside in the vehicle width direction, a shaft part connected to the inside in the vehicle width direction of the head part, and a screw shaft protruding to the inside in the vehicle width direction of the pivot part 22.

[0041] The shaft portion of the stepped bolt 25a is inserted through the shaft insertion hole of the plate portion 22a on the outer side of the pivot portion 22 in the vehicle width direction and the shaft insertion hole of the stand connecting portion 32. The screw shaft of the stepped bolt 25a is inserted through the shaft insertion hole of the plate portion 22b on the inner side of the pivot portion 22 in the vehicle width direction. The nut 25b is screwed and tightened onto the screw shaft protruding inward in the vehicle width direction of the pivot portion 22, thereby fixing the stepped bolt 25a to the plate portion 22b on the inner side in the vehicle width direction. In this state, the pivot portion 22 is rotatably connected (supported) to the stand connecting portion 32 via the stepped bolt 25a.

[0042] The stand bracket 31 has a locking portion that locks the other end (front end) of the stand spring SP. The stand spring SP is stretched between the locking hook 29 of the stand member 21 and the locking portion of the stand bracket 31. The stand spring SP maintains the rotation position of the stand member 21 in the standing position or the stored position by its own tension. The urging direction of the stand member 21 by the stand spring SP switches at the midpoint of the rotation range, so that the stand member 21 is urged toward the standing position when it is closer to the standing position, and is urged toward the stored position when it is closer to the stored position.

[0043] <Stand storage recess 34> 2 to 5, the left floor side cover 11eL that covers the periphery of the stand bracket 31 is formed with a storage recess 34 for storing the stand member 21 in the storage position. Referring to the cross section, the storage recess 34 is formed to be recessed inward in the vehicle width direction with respect to the curved cover outer surface 11e1 of the left floor side cover 11eL that is convex downward and outward in the vehicle width direction. The storage recess 34 includes a substantially horizontal upper wall portion 34a that covers the upper end of the stand storage space, and an inner wall portion 34b that extends obliquely downward and inward in the vehicle width direction from the inner end of the upper wall portion 34a in the vehicle width direction.

[0044] Here, the left and right lower frames 16c are attached with a plate-shaped frame member 16e at a position overlapping the rear portion of the storage recess 34 in a side view so as to sandwich the pipe-shaped left lower frame member 16cL in the vehicle width direction. In order to avoid the frame member 16e, an overhanging portion (bulging portion) 36 that overhangs downward and toward the outside in the vehicle width direction is formed on the inner wall portion 34b of the storage recess 34. The overhanging portion 36 includes a vertical wall portion 36a that extends downward from the vicinity of the outer end of the upper wall portion 34a, and a horizontal wall portion 36b that extends substantially horizontally toward the inside in the vehicle width direction from the lower end of the vertical wall portion 36a. The corners of the vertical wall portion 36a and the horizontal wall portion 36b are defined as the top portion 36c of the overhanging portion 36. In the drawing, the reference symbol 16f indicates a cross frame that connects the left and right lower frames 16c to each other.

[0045] The overhanging portion 36 overlaps with the connection portion 23 of the stand member 21 in the stored position in a side view. At this time, the connection portion 23 is formed in a plate shape with the plate thickness direction facing the vehicle width direction, so that a sufficient gap between the overhanging portion 36 and the connection portion 23 is secured. The top 36c of the overhanging portion 36 is close to an extension portion of the rotation region R1 of the stand member 21 (a virtual region extending the rotation region R1 in the circumferential direction). However, the top 36c of the overhanging portion 36 is located lower than the upper end of the connection portion 23 of the stand member 21 in the stored position in the vehicle up-down direction. For this reason, the raised portion 26 formed on the upper edge portion 23c of the connection portion 23 is unlikely to approach the top 36c of the overhanging portion 36, and the gap between the overhanging portion 36 and the stand member 21 is prevented from being locally reduced.

[0046] As described above, the side stand structure in the above embodiment includes the stand member 21 that is pivotally supported on one of the left and right sides of the vehicle body and is provided so as to be rotatable between an upright position and a stored position, the stand member 21 includes a pivot portion 22 that is rotatably connected to the vehicle body, a ground contact portion 24 that comes into contact with the ground when the stand member 21 is in the upright position, and a plate-shaped connecting portion 23 that connects the pivot portion 22 and the ground contact portion 24, the connecting portion 23 is disposed such that a plate thickness direction F3 of the connecting portion 23 faces the vehicle width direction when the stand member 21 is in the stored position, and ... the plate thickness direction F3 of the connecting portion 23 faces the vehicle width direction, and the connecting portion 23 faces the stand member 21. The upper edge portion 23c, which is located on the upper side in the vertical direction of the vehicle when the member 21 is in the storage position, is provided with a raised portion 26 that raised inward in the vehicle width direction in the plate thickness direction F3, and the portion of the upper edge portion 23c on the ground contact portion 24 side in the extension direction F1 (the portion adjacent to the ground contact portion 24) is provided with a protrusion 27 that protrudes outward in the vehicle width direction in the plate thickness direction F3 and serves as an operating portion when rotating the stand member 21, and the raised portion 26 and the protrusion 27 respectively have a raised upper surface portion 26a and a protruding upper surface portion 27a that face upward in the vertical direction of the vehicle when the stand member 21 is in the storage position, and the raised upper surface portion 26a and the protruding upper surface portion 27a are formed flush and continuous with each other.

[0047] According to this configuration, the stand member 21 having the plate-shaped connecting portion (arm portion) 23 can reduce the weight of the stand member 21 and improve the appearance by making the wide surface on one side in the plate thickness direction F3 of the connecting portion 23 the external appearance surface. The raised portion (thick portion) 26, which is the reinforcing portion of the connecting portion 23, and the protruding portion 27, which is the rotation operation portion 27 of the stand member 21, are connected in a flush manner, so that the input during stand operation can be distributed in the extension direction (length direction) F1 of the stand member 21 and effectively received.

[0048] In the above-mentioned side stand structure, the connection portion 23 has an outer surface portion 23a facing outward in the vehicle width direction and an inner surface portion 23b facing inward in the vehicle width direction, and the inner surface portion 23b is located below the raised portion 26 when the stand member 21 is in the stored position. According to this configuration, when the stand member 21 is in the storage position, the inner surface of the connection portion 23 is positioned below the raised portion 26, making the inner surface side of the connection portion 23 less visible and improving the appearance.

[0049] In the above-described side stand structure, the raised portion 26 is located at the outer end of the connecting portion 23 in the vehicle width direction when the stand member 21 is in the upright position. According to this configuration, the raised portion 26 formed on one side edge of the plate-shaped connecting portion 23 is positioned at the outer end in the width direction of the vehicle when the stand is upright, thereby making the plate-shaped connecting portion 23 appear thick when the stand is upright while making the inner side of the connecting portion 23 less visible, thereby improving the appearance.

[0050] In the above-mentioned side stand structure, a vehicle body cover member (left floor side cover 11eL) is provided which covers the periphery of the stand support portion (stand bracket 31) on the vehicle body, and the left floor side cover 11eL is provided with a storage recess 34 for storing the stand member 21 in the storage position, and on the inside of the storage recess 34 is provided with a protruding portion 36 which protrudes toward the inner surface portion 23b of the stand member 21 in the storage position. According to this configuration, by providing the storage recess 34 that stores the stand member 21 in the storage position with the overhanging portion 36 that overhangs toward the inner surface of the stand member 21, the stand member 21 and the left floor side cover 11eL are closer to each other in the stand storage state, and the gap between the stand member 21 and the left floor side cover 11eL can be reduced to improve the appearance. The storage recess 34 is concave when viewed from outside the vehicle, but even if a structure such as the body frame 16 is present on the rear side of the storage recess 34, the overhanging portion 36 covers the structure, hiding it and improving the appearance in the stand upright state, while ensuring a gap between the structure and the left floor side cover 11eL to suppress interference between vehicle parts.

[0051] In the above-mentioned side stand structure, at least the end (top 36c) of the protrusion 36 on the inner surface 23b side is close to a virtual area obtained by extending the rotation area R1 of the stand member 21 in the circumferential direction, and the end (top 36c) of the protrusion 36 is located lower than the connection portion 23 of the stand member 21 in the storage position in the vertical direction of the vehicle. With this configuration, the end portion (top 36c) of the protrusion 36 on the inner surface of the stand is close to the extension portion 24b of the rotation area R1 of the stand member 21, while the top 36c of the protrusion 36 is positioned lower than the connection portion 23, making it possible to position the raised portion 26 above the top 36c of the protrusion 36, and efficiently securing space to avoid the raised portion 26 and storing the stand member 21.

[0052] The present invention is not limited to the above-described embodiment. For example, the side stand structure of the present embodiment may be applied to a saddle-type vehicle other than a motorcycle, as long as the vehicle is equipped with a side stand. The saddle-type vehicle includes all vehicles on which the driver straddles the body, and includes not only motorcycles (including motorized bicycles and scooter-type vehicles), but also three-wheeled vehicles (including vehicles with one wheel in front and two wheels in the rear, as well as vehicles with two wheels in front and one wheel in the rear) or four-wheeled vehicles (such as four-wheeled buggies). The configurations in the above-described embodiments are merely examples of the present invention, and various modifications are possible without departing from the gist of the present invention, such as replacing the components of the embodiments with well-known components.
