Fig. 4 is a left side view of the main stand 50 in the housed state. Fig. 5 is a front view of the main stand 50 in the housed state. Fig. 6 is a bottom view of the main stand 50 in the housed state. Fig. 7 is a plan view of the main stand 50 in the housed state. Fig. 6 corresponds to a view seen in the direction of arrow VI in fig. 5, and fig. 7 corresponds to a view seen in the direction of arrow VII in fig. 5.

In the following description of the main rack 50, unless otherwise specified, the description of the directions of the front, rear, up and down is used for the main rack 50 in the housed state. The fixing of the respective portions of the main frame 50 is performed by, for example, welding, unless otherwise noted.

The main bracket 50 includes a U-shaped body portion 51 that is open rearward. The main body 51 is formed of a pipe material. The main body 51 includes: a connecting portion 51A (see fig. 6 and 7) that extends while being bent in the left-right direction (vehicle width direction); a left leg portion 51B (see fig. 6 and 7) extending rearward from a left end (one end in the vehicle width direction) of the connecting portion 51A; and a right leg portion 51C (see fig. 6 and 7) extending rearward from a right end (the other end in the vehicle width direction) of the connecting portion 51A. The space between the left leg portion 51B and the right leg portion 51C is formed to be wider than the width of the rear wheel 15 (see fig. 2 and 3). The ground plates 80 and 90 are fixed to the ground surfaces 51B1 and 51C1 (see fig. 7) which are the end portions on the open end side of the main body 51.

A tubular rotation shaft portion 52 extending in the vehicle width direction is fixed to the main body portion 51. The length of the rotation shaft portion 52 in the lateral direction is shorter than that of the main body portion 51. The rotation shaft portion 52 is fixed to the main body portion 51 via a pair of left and right first plates 53, 54 and a pair of left and right second plates 55, 56. The main body 51 and the rotation shaft 52 are fixed in a state sandwiched by the first plates 53, 54 and the second plates 55, 56. The main body 51 rotates integrally with the rotation shaft 52.

The first plates 53, 54 are formed in a flat plate shape. The first plates 53, 54 are fixed so that the thickness direction corresponds to the radial direction of the rotation shaft portion 52. The first plates 53, 54 are fixed to the main body 51 and the rotation shaft 52 so as to be in surface contact.

As shown in fig. 6, the first plates 53 and 54 include: rotation fixing portions 53A, 54A fixed to the rotation shaft portion 52; connection portions 53B, 54B extending radially outward (rearward) from the rotation fixing portions 53A, 54A; and main body fixing portions 53C, 54C formed at radially outer ends (rear ends) of the connecting portions 53B, 54B and fixed to the main body portion 51. The left main body fixing portion 53C extends along the left portion of the main body portion 51 in a curved manner. The right main body fixing portion 54C extends along the right portion of the main body 51 in a curved manner. Here, the left main body fixing portion 53C is formed longer than the right main body fixing portion 54C on the outer side in the radial direction. The left main body fixing portion 53C extends to a position further to the rear than the engagement portion 57A (see fig. 6) of the operation portion 57.

The second plates 55, 56 are fixed to the first plates 53, 54 on the opposite side of the rotation shaft portion 52. As shown in fig. 5, the second plates 55, 56 are fixed to the rotation shaft portion 52 and the main body portion 51 so as to be in so-called line contact with respect to the first plates 53, 54 that are in surface contact. That is, the second plates 55, 56 are fixed in the thickness direction corresponding to the vehicle width direction, and the side surfaces of the thickness are fixed to the rotating shaft portion 52 and the main body portion 51. Therefore, the second plates 55, 56 are fixed to the rotation shaft portion 52 and the main body portion 51 in a state where rigidity is easily increased as compared with the first plates 53, 54.

As shown in fig. 7, the left and right second plates 55, 56 extend in the radial direction (front-rear direction) and are fixed so as to overlap the left and right first plates 53, 54, respectively, in a plan view. The second plates 55, 56 include: rotation fixing portions 55A, 56A fixed to the rotation shaft portion 52; connection portions 55B, 56B extending radially outward from the rotation fixing portions 55A, 56A; and main body fixing portions 55C, 56C formed at the radially outer ends of the connecting portions 55B, 56B and fixed to the main body portion 51. The main body fixing portions 55C, 56C of the left and right second plates 55, 56 are bent outward in the vehicle width direction as they are radially apart from the connecting portions 55B, 56B.

A left leg portion 51B of the main body 51 is fixed with a bent tubular operation portion 57 extending leftward. The operation portion 57 extends outward in the vehicle width direction when viewed from the front (see fig. 5), and is inclined upward as it advances outward in the vehicle width direction. In a side view of the vehicle (see fig. 4), the operation portion 57 extends upward. A pedal 58 that can be pressed by an occupant's foot is fixed to an upper end (front end) of the operation portion 57. The pedal 58 is formed in a plate shape that is inclined rearward as it advances upward in the stored state.

A plate-like engagement plate 59 is fixed to a front portion of the outer peripheral surface of the operation portion 57. The engagement plate 59 extends along the front of the operation portion 57. The engagement plate 59 is engaged so as to abut against the front portion of the outer peripheral surface of the operation portion 57. A sheet-like spring engaging portion 59A is formed at the vehicle width direction inner end of the engaging plate 59. One end 70A (see fig. 6 and 7) of the coil spring 70 is hooked to the spring engagement portion 59A.

A plate-shaped gusset 60 is fixed to the rear portion of the outer peripheral surface of the operation portion 57. The gusset 60 extends along the rear of the operating portion 57. The gusset 60 is joined so as to abut against the rear portion of the outer peripheral surface of the operation portion 57. The inner end of the gusset 60 in the vehicle width direction is fixed to the left leg portion 51B of the main body portion 51. The operation portion 57 is reinforced by the gusset 60.

The damper portion 61 is provided on the opposite side of the gusset 60 in the vehicle width direction from the main body portion 51. The damper portion 61 includes a plate portion 62 fixed to the main body portion 51 and a rubber (cushioning member) 63 fixed to the plate portion 62. The rubber 63 extends in the front-rear direction, and has a wave shape in the middle-upper portion in a cross section viewed from the front (see fig. 8). The rubber 63 of the damper portion 61 protrudes upward from the ground plate 80 (see fig. 4). When the main bracket 50 is moved from the raised state to the housed state by the damper portion 61, the shock of contact with the transmission case portion 40 of the power unit 12 can be alleviated even if the main bracket 50 is excessively rotated.

A coupling shaft 64 extending in the vehicle width direction penetrates the rotating shaft portion 52. A drop-off prevention plate 65 is fixed to a left end portion (one end portion in the vehicle width direction) of the connecting shaft 64. A spring engagement pin 66 is provided at a position of the retaining plate 65 eccentric to the connecting shaft 64. The spring engagement pin 66 is a shaft member protruding leftward with respect to the release prevention plate 65. An annular fitting groove 66A is formed in the outer peripheral surface of the tip end portion of the spring engagement pin 66 (see fig. 6 and 7). The other end 70B of the coil spring 70 is connected to the fitting groove 66A (see fig. 6 and 7).

Here, the rotation shaft portion 52 of the main bracket 50 is supported by the left and right bracket brackets 23b, 23c via a connecting shaft 64 (see fig. 5). That is, the rotation shaft portion 52 is disposed between the left and right bracket brackets 23b, 23c, and the connecting shaft 64 is inserted from the right end (front end). Thus, the connecting shaft 64 penetrates the left bracket 23b, the rotation shaft 52, and the right bracket 23c in this order. When the drop-off preventing pin 67 is attached to the right end portion (the other end portion in the vehicle width direction) of the connecting shaft 64, the connecting shaft 64 is prevented from dropping off from the left and right bracket brackets 23b, 23c by the drop-off preventing plate 65 and the drop-off preventing pin 67. The drop-off prevention plate 65 is fixed to the crankcase 23 by bolts 68.

Therefore, the rotation shaft portion 52 is rotatably supported by the bracket brackets 23b and 23c about the coupling shaft 64.

When the main stand 50 rotates about the rotation shaft 52, the distance between the spring engagement portion 59A and the eccentric spring engagement pin 66 changes, and the up state and the stored state are set across the farthest positions. Therefore, when moving between the raised state and the stored state, the coil spring 70 moves to either one of the raised state and the stored state after being extended to the maximum extent. The main stand 50 is held in either one of the standing state and the housed state by the elastic restoring force of the coil spring 70.

The ground plates 80 and 90 fixed to the main body 51 are formed by bending a metal plate material. The ground plates 80, 90 are press-molded products.

The left (vehicle width direction side) ground panel 80 includes an inclined surface 81 below the left leg portion 51B. The inclined surface 81 is formed in a plate shape inclined downward as it goes rearward (see fig. 4). An outer peripheral edge 81A recessed rearward (on a side radially away from the rotation shaft portion 52) is formed at a front portion (rotation shaft portion 52 side) of the inclined surface 81. The outer peripheral surface of the left leg portion 51B of the main body portion 51 is disposed along the outer peripheral edge 81A. A plate-shaped ground plane 82 bent upward is formed at the rear end of the inclined surface 81.

The ground plane 82 is formed in a trapezoid (refer to fig. 9). The ground plane 82 is formed so as to have a larger width in the left-right direction as it goes upward. The outer edge (outer end) of the ground plane 82 in the vehicle width direction is inclined more outward in the vehicle width direction as it goes upward than the inner edge (inner end) in the vehicle width direction.

The ground plane 82 is curved in an arc shape (see fig. 10) and protrudes rearward in cross section. A ground plane 51B1 of the left leg 51B is fixed to the inner surface of the ground plane 82. Thereby, the ground plate 80 is fixed to the main body 51 of the main bracket 50.

A plate-shaped inner end surface 83 that is bent upward is formed at the vehicle width direction inner end of the inclined surface 81. The inner end surface 83 is disposed further inward in the vehicle width direction than the left leg portion 51B of the main body portion 51. The rear end of the inner end surface 83 is welded to the inner edge of the ground plane 82 in the vehicle width direction. The inner end face 83 is connected to the ground plane 82. A relief hole 80A (see fig. 6) is formed in the inner end surface 83 and the inclined surface 81 side of the ground plane 82 during bending.

A plate-shaped outer end surface 84 that is bent upward is formed at the vehicle width direction outer end of the inclined surface 81. The outer end surface 84 is plate-shaped and curved upward as it proceeds outward in the vehicle width direction. As shown in fig. 8 and 9, the outer end surface 84 extends from a position overlapping the left leg portion 51B of the main body portion 51 to a position outside the left leg portion 51 in the vehicle width direction. The outer end surface 84 is curved outward in the vehicle width direction along the vehicle width direction outer edge of the ground plane 82. The outer end surface 84 is not soldered to the ground plane 82. A relief hole 80B (see fig. 6) is formed in the outer end surface 84 and the inclined surface 81 side of the ground plane 82 during bending.

The inclined surface 81 has a convex portion 85 recessed on the inner surface side and protruding toward the outer surface side. The convex portion 85 protrudes downward with respect to the inclined surface 81. In the present embodiment, the convex portion 85 has a cylindrical shape, which is a side surface shape of a cylinder having an axis extending in the left-right direction. The top 85A (see fig. 10) of the protrusion 85 having the largest protruding height (protruding amount) with respect to the inclined surface 81 is directed forward and downward. The top 85A extends in the left-right direction along the axis of the cylindrical shape. The convex portion 85 is a cylindrical surface shape having a small curvature, and the protruding height gradually decreases toward the inclined surface 81 in the front-rear direction, and is connected to the inclined surface 81 at a gentle inclination. The top 85A is formed at the front-rear direction center portion of the convex portion 85.

The protruding height of the protruding portion 85 decreases outward in the vehicle width direction toward the inclined surface 81. In the present embodiment, inclined portions 85B (see fig. 9) that incline upward as advancing outward in the vehicle width direction are formed at the outer ends of the protruding portions 85 in both vehicle width directions. The protruding portion 85 protrudes substantially uniformly in the vehicle width direction except for the inclined portion 85B. The inclined portion 85B allows the convex portion 85 to be easily connected to the inclined surface 81 with a gentle inclination in the vehicle width direction.

The convex portion 85 is connected to the inclined surface 81 at an inclination angle of less than 45 ° in the front-rear direction (see fig. 10.) the convex portion 85 is connected to the inclined surface 81 at an inclination angle of less than 90 ° in the vehicle width direction by the inclined portion 85B (see fig. 9). The convex portion 85 is connected to the inclined surface 81 at a smaller inclination angle in the front-rear direction than in the vehicle width direction.

The outer end surface 84 has a second convex portion 86 recessed on the inner surface side and protruding toward the outer surface side. The second convex portion 86 protrudes with respect to the outer end surface 84 and is directed downward and outward in the vehicle width direction. In the present embodiment, the second protruding portion 86 has a cylindrical side surface shape having an axis extending in the up-down direction (see fig. 4). The top 86A (see fig. 6) of the second protruding portion 86 extends along the cylindrical axis of the second protruding portion 86. The second convex portion 86 has a cylindrical surface shape with a small curvature, and extends so that the protruding height thereof becomes gradually higher from the front side with respect to the outer end surface 84, and is connected with a gentle inclination. The top 86A is formed at the front-rear direction center portion of the second protruding portion 86. The second convex portion 86 is connected to the outer end surface 84 at an angle smaller than 45 ° on the front side (see fig. 9).

A right (other side in the vehicle width direction) ground panel 90 is fixed to a ground plane 51C1 (see fig. 3 and 7) of the right leg portion 51C of the main body 51. The right ground plate 90 is formed to be substantially laterally symmetrical to the left ground plate 80 except that the outer end surface 84 of the left ground plate 80 is omitted. That is, the right ground plate 90 includes an inclined surface 91, a ground surface 92, an inner end surface 93, a convex portion 95, a top 95A, an inclined portion 95B, and a relief hole 90A corresponding to the inclined surface 81, the ground surface 82, the inner end surface 83, the convex portion 85, the top 85A, the inclined portion 85B, and the relief hole 80A of the left ground plate 80.

As shown in fig. 5, the right protruding portion 95 is formed wider than the left protruding portion 85 in the vehicle width direction. In the right protruding portion 95, the inclined portion 95B at the outer end in the vehicle width direction is omitted. As a result, the main support 50 can change the structures of the left and right ground plates 80 and 90, and can balance the influence of the traveling wind in consideration of the weight of the muffler 25A (see fig. 3) of the exhaust device 25 provided on the right side, for example.

A guide plate 96 is fixed to the right foot 51C in front of the ground plate 90. As shown in fig. 5, the guide plate 96 is a curved plate-like plate that is convexly curved outward in the vehicle width direction. The guide plate 96 is formed to widen in width as it advances rearward. The guide plate 96 overlaps the ground plane 92 of the ground plate 90 when viewed from the front. The guide plate 96 easily guides the traveling wind and water blown from the front to the outside in the vehicle width direction, and suppresses the traveling wind and water from blowing to the inner surface (front surface) of the ground plane 92 of the right ground panel 90.

Next, the operation of the present embodiment will be described.

When the saddle type vehicle 10 is parked, for example, the main stand 50 is in an upright state and the ground contact panels 80 and 90 of the main stand 50 are grounded. When the saddle-type vehicle 10 travels, the main frame 50 is rotated from the raised state to the stored state.

The saddle-type vehicle 10 receives traveling wind from the front during traveling. At this time, in the main stand 50, as shown by arrows A1 to A3 in fig. 2 and 3, the traveling wind flows along the inclined surfaces 81 and 91. In the present embodiment, since the inclined surfaces 81 and 91 are provided with the projections 85 and 95, the traveling wind is guided by the projections 85 and 95. That is, the traveling wind is guided by the convex portions 85 and 95 in the backward and downward direction away from the main stand 50, and is guided by the convex portions 85 and 95 upward along the ground contact panels 80 and 90. Therefore, the traveling wind guided downward by the convex portions 85, 95 is reduced, and the lift generated by the traveling wind is suppressed, so that the ground contact load of the rear wheel 15 is easily increased, as compared with the case where the convex portions 85, 95 are not provided on the inclined surfaces 81, 91.

The protruding portions 85, 95 are also connected so that the protruding height becomes lower toward the inclined surfaces 81, 91 and also becomes lower toward the outer side in the vehicle width direction. Therefore, even when the saddle type vehicle 10 turns or leans and the saddle type vehicle 10 turns in the roll direction, the flow of the traveling wind is easily guided.

In particular, in the present embodiment, the main bracket 50 is supported by the crankcase 23 and overlaps the rear wheels 15 in a side view of the vehicle. Therefore, the main bracket 50 is provided at a position away from the center of gravity of the saddle-type vehicle 10 and close to the rear wheel 15, and thus is provided at a position that easily affects the rear of the vehicle body. In the present embodiment, since the main bracket 50 is provided with the ground contact panels 80 and 90 having the protruding portions 85 and 95, the ground contact load of the rear wheel 15 can be easily and appropriately increased. Further, by changing the shape of the left and right ground plates 80, 90 of the main bracket 50, the left and right posture change can be adjusted.

Further, an outer end surface 84 is formed on the left ground plate 80. The running wind is guided outward in the vehicle width direction by the outer end surface 84. At this time, for example, although water on the road splashes and faces the ground plane 80 together with the traveling wind, the traveling wind and water are easily guided downward in the vehicle width direction outside by the outer end surface 84, and the water is suppressed from entering the ground plane 82. Therefore, water is prevented from entering the inner surface of the ground plane 82 and splashing toward the air inlet 45a of the air cleaner box 45.

As described above, according to the embodiment to which the present utility model is applied, the saddle-type vehicle 10 includes: a main body 51 of the main stand 50; ground plates 80, 90 attached to the ground surfaces 51B1, 51C1 of the main body 51; and inclined surfaces 81, 91 provided at portions of the ground contact panels 80, 90 that are on the front side in a stored state when the main stand 50 is traveling, wherein the inclined surfaces 81, 91 include protrusions 85, 95 protruding forward and downward from the inclined surfaces 81, 91 in a stored state when the main stand 50 is traveling. Therefore, in the saddle type vehicle 10 in which the main stand 50 includes the inclined surfaces 81, 91, the ground contact load of the rear wheels 15 can be increased while suppressing air resistance caused by the traveling wind.

In the present embodiment, a pair of ground panels 80, 90 are provided in the vehicle width direction in the main body portion 51 of the main stand 50. Therefore, the vehicle can receive the running wind in the vehicle width direction, and the influence of the running wind can be balanced in the vehicle width direction.

In the present embodiment, the connecting portions of the protruding portions 85, 95 to the inclined surfaces 81, 91 in the vehicle width direction are formed so that the protruding heights thereof are lower toward the outer sides of the inclined surfaces 81, 91 in the vehicle width direction. Accordingly, the convex portions 85 and 95 have shapes that gradually protrude from the inclined surfaces 81 and 91 in the vehicle width direction, and therefore, air resistance when the vehicle body is inclined due to roll or the like can be reduced.

In the present embodiment, in the storage state of the main stand 50 during traveling, the inclination angle of the protruding portions 85, 95 with respect to the inclined surfaces 81, 91 is smaller in the front-rear direction than in the vehicle width direction. Accordingly, since the convex portions 85 and 95 have a front-rear shape having gentle inclination with respect to the inclined surfaces 81 and 91, the ground contact load of the rear wheel 15 can be further increased.

In the present embodiment, in the storage state of the main stand 50 during traveling, the top portions 85A and 95A of the protruding portions 85 and 95 are positioned at the front-rear center portions of the protruding portions 85 and 95. Therefore, since the top portions 85A and 95A are positioned at the front-rear center portions, the traveling wind is easily guided in a balanced manner, and the ground contact load of the rear wheels 15 can be further increased.

The above-described embodiment merely shows one embodiment of the present utility model, and can be arbitrarily modified and applied within a range not departing from the gist of the present utility model.

In the above embodiment, the main stand 50 is preferably provided to the unit swing type power unit 12, and the main stand 50 is separated rearward from the center of gravity of the vehicle and is close to the rear wheel 15, but is not limited thereto. For example, the structure of the present application may be applied to a saddle-type vehicle 10 having a main bracket provided to a vehicle body frame 11.

In the above-described embodiment, the main bracket 50 having the pair of contact surfaces 51B1, 51C1 in the vehicle width direction has been described as a bracket, but the bracket may be a side bracket having only one contact surface in the vehicle width direction, for example, the side bracket 39 of the above-described embodiment may be provided on a contact panel having a convex portion on an inclined surface.

In the above-described embodiment, the motor bicycle having the front wheels 13 and the rear wheels 15 has been described as an example of the saddle-type vehicle 10, but the present utility model is not limited to this, and the present utility model is applicable to a three-wheeled saddle-type vehicle having two front wheels or rear wheels or a saddle-type vehicle having four or more wheels.
