[0035] One end of a return spring 56 is connected to the spring engaging portion 55c. The other end of the return spring 56 is connected to the pivot frame 32 via a swing arm 57. The swing arm 57 is swingably supported on the stand engaging pin 32h (see FIG. 4). The swing arm 57 is curved in a sickle shape in a side view of the vehicle body. In a bottom view, the swing arm 57 extends and inclines outward in the vehicle width direction as it moves away from the stand engaging pin 32h. When the main stand 55 moves to the parking position, the swing arm 57 also rotates, allowing the return spring 56 to expand and contract while avoiding the stand pivot shaft 54.

[0036] A brake pedal 53 is supported on the right side of the main stand 55 so as to be able to swing. The brake pedal 53 has an arm portion 53a extending in the front-rear direction, a tubular portion 53b provided at the upper rear portion of the arm portion 53a and extending in the vehicle width direction, and a swing plate portion (brake operating portion) 53c extending upward from the tubular portion 53b. The brake pedal 53 has the tubular portion 53b disposed on the right side of the right side surface portion 32b. The stand pivot shaft 54 ​​is inserted into the tubular portion 53b. This allows the brake pedal 53 to be swingably supported with respect to the body frame 11. The swing plate portion 53c (see FIG. 9) is formed with a stopper portion 53d that curves outward in the vehicle width direction as it extends rearward. The stopper portion 53d enters a pedal entry portion 76 of the reinforcing member 70. The stopper portion 53d overlaps the reinforcing member 70 in a bottom view. When the stopper portion 53d abuts against the pedal entrance portion 76, excessive rotation of the brake pedal 53 is restricted.

[0037] A spring stay 53e is fixed to the arm portion 53a. One end of a return spring 58 is engaged with the spring stay 53e. The other end of the return spring 58 is engaged with the engaging portion 28b of the step rod 28a. This biases the brake pedal 53 toward the normal position (see FIG. 1). When the brake pedal 53 is operated against the tensile force of the return spring 58, the brake pedal 53 moves toward the operating position (see FIG. 12).

[0038] A bent rod-shaped hook portion 53f (see FIG. 7) is formed on the upper surface of the spring stay 53e. One end of a switch spring 59 extending upward is engaged with the hook portion 53f. The other end of the switch spring 59 is engaged with a brake switch 60 (see FIG. 3). The brake switch 60 is supported by a bracket 69 fixed to the right side surface portion 32b of the pivot frame 32. A harness 60a extends from the brake switch 60. When the brake pedal 53 is operated and the brake switch 60 is pulled via the switch spring 59, the stop lamp 30 (see FIG. 1) at the rear end of the vehicle body is turned on.

[0039] Fig. 6 is a right side view showing the periphery of the pivot frame 32. Fig. 7 is a view showing a state in which the exhaust device 25 has been removed from Fig. 6. Fig. 8 is a perspective view of the reinforcing member 70 as seen from the inside in the vehicle width direction. A metallic reinforcing member 70 is supported on the pivot frame 32. The reinforcing member 70 extends parallel to the pivot frame 32. The reinforcing member 70 is disposed along the right side surface portion 32b of the pivot frame 32.

[0040] The reinforcing member 70 has a plate-shaped main body 71 that extends in the vertical direction. An upper support portion 72 and a lower support portion (second pivot support portion) 73, each having a hole shape, are formed above and below the main body 71. The upper support portion 72 and the lower support portion 73 are formed so that their positions in the front-to-rear direction are approximately the same. In other words, the upper support portion 72 and the lower support portion 73 are formed at positions where a predetermined straight line L1 extending in the vertical direction passes through the pivot shaft 22 and bolt 49 that are inserted therethrough, as seen from the side of the vehicle body.

[0041] An upper muffler fixing seat 74 is formed at the rear lower part of the upper support part 72. The upper muffler fixing seat 74 is formed in a cylindrical shape. The upper muffler fixing seat 74 protrudes in the vehicle width direction by a predetermined amount from the plate-shaped outer surface of the reinforcing member 70. A lower muffler fixing seat 75 is formed in front of the lower support part 73. The lower muffler fixing seat 75 is formed in a cylindrical shape. The lower muffler fixing seat 75 protrudes in the vehicle width direction by a predetermined amount from the outer surface of the main body part 71. The lower muffler fixing seat 75 is located slightly below the lower support part 73. Specifically, the center of the hole in the lower muffler fixing seat 75 is located below the center of the hole in the lower support part 73.

[0042] A pedal entrance portion 76 having an upwardly recessed outer periphery is formed behind the lower muffler fixing seat 75. The pedal entrance portion 76 has an abutment portion 76a formed by bending the outer periphery of the main body portion 71.

[0043] A hole-shaped pin fitting portion 77 that penetrates the main body portion 71 in the vehicle width direction is formed above the pedal entrance portion 76. The pin fitting portion 77 is located between the upper support portion 72 and the lower support portion 73. The pin fitting portion 77 is located between the upper muffler fixing seat 74 and the lower support portion 73. A support pin 78 that protrudes inward in the vehicle width direction is supported by the pin fitting portion 77. A bent plate-shaped spring engagement stay 79 that extends rearward is fixed above the pin fitting portion 77. The spring engagement stay 79 is fixed to the inner surface of the main body portion 71 by welding, for example. The spring engagement stay 79 extends in the front-rear direction. A folded portion 79a that is bent in the vehicle width direction is formed at the front end of the spring engagement stay 79. A spring engagement portion 79b that has a notch that can be used to hook a spring is formed at the rear end of the spring engagement stay 79.

[0044] The upper support portion 72 of the reinforcing member 70 is fastened together with the swing arm 16 by the pivot shaft 22. That is, the pivot shaft 22 has a bolt-shaped pivot shaft main body portion 22a and a nut portion 22b that is fastened to the pivot shaft main body portion 22a. As shown in FIG. 4, the pivot portions 16d, 16e of the swing arm 16 are disposed on the left and right sides of the upper support portion 72. The pivot shaft main body 22a is inserted into the pivot portion 16d from the left side. The pivot shaft main body 22a passes through the left pivot portion 16d, the pivot shaft support portion 32d, and the right pivot portion 16e in that order, and is then inserted into the upper support portion 72 of the reinforcing member 70. The nut portion 22b is fastened to the pivot shaft main body 22a from the right side. As a result, the reinforcing member 70 is fastened together with the swing arm by the pivot shaft 22. Therefore, the support strength and support rigidity of the reinforcing member 70 can be ensured by utilizing the pivot shaft 22, which extends in the vehicle width direction and is firmly supported.

[0045] A bolt 49 is inserted into the lower support portion 73 from the right side. The bolt 49 is inserted into the reinforcing member support portion 32e of the pivot frame 32. The reinforcing member 70 is fixed at the top and bottom, and is attached with a predetermined space between it and the right side surface portion 32b of the pivot frame 32. The reinforcing member 70 is fixed at two points, top and bottom, and its strength tends to be greatest on the straight line L1 extending in the vertical direction.

[0046] A muffler 82 of the exhaust device 25 is attached to the reinforcing member 70. The exhaust device 25 is connected to an exhaust port on the underside of the cylinder section 24. The exhaust pipe 81 extends downward and then rearward, extending rearward below the power unit 12. A muffler 82 is connected to the rear end of the exhaust pipe 81. The muffler 82 extends upward toward the rear. At the front end, the diameter of the muffler 82 increases as it moves rearward.

[0047] A front end stay (front support portion) 83 is formed at the lower front end portion of muffler 82. Front end stay 83 has a generally U-shaped cross section (see FIG. 5). An intermediate stay (rear support portion) 84 is formed at the upper front end portion of muffler 82, rearward of front end stay 83. Intermediate stay 84 is formed in the shape of a plate that is thick in the vehicle width direction. A rear upper stay 85 that extends upward is formed at the upper rear end of muffler 82. Rear upper stay 85 is formed in the shape of a plate that is thick in the vehicle width direction. The front-end stay 83, the intermediate stay 84, and the upper rear stay 85 are positioned approximately in the same position in the vehicle width direction (see FIG. 5). That is, the fixing points of the front-end stay 83, the intermediate stay 84, and the upper rear stay 85 are positioned on a straight line L2 that extends in the vertical direction. The exhaust pipe 81, the muffler 82, the front end stay 83, the intermediate stay 84, and the rear upper stay 85 constitute the exhaust device 25 of this embodiment.

[0048] The front end stay 83 and the intermediate stay 84 of the muffler 82 are fixed to the reinforcing member 70. Therefore, the muffler 82 is supported on the pivot frame 32 via the reinforcing member 70. Furthermore, the rear upper stay 85 is fixed to the pillion step bracket 52. Therefore, the muffler 82 is fixed to the right rear subframe 34 via the pillion step bracket 52. Because the muffler 82 is attached to the body frame 11 via the reinforcing member 70, assembly of the muffler 82 is facilitated. Furthermore, the front end stay 83 and the intermediate stay 84 of the muffler 82 only need to be sized so that they can be attached to the reinforcing member 70, making it easier to support the muffler 82 while ensuring strength and rigidity and preventing an increase in the size of the support portion for the muffler 82.

[0049] Here, the upper support portion 72 of the reinforcing member 70 is located above the upper surface of the muffler 82. The lower support portion 73 of the reinforcing member 70 is located below the lower surface of the muffler. Therefore, the reinforcing member 70 is supported by the pivot frame 32 at a position that is vertically spaced apart from the muffler 82, and the reinforcing member 70 makes it easier to stably support the muffler 82.

[0050] Furthermore, the front-end stay 83 is located forward of the straight line L1 in a side view of the vehicle body. The middle stay 84 is located rearward of the straight line L1 in a side view of the vehicle body. Therefore, the muffler 82 is supported in such a way that it is distributed between the front and rear of the support portion of the reinforcing member 70. This makes it possible to suppress the concentration of stress acting on the reinforcing member 70 from the muffler 82. Furthermore, by utilizing the flexibility of the front and rear portions of the reinforcing member that are away from the straight line L1, it is possible to make it easier to absorb vibrations of the muffler 82.

[0051] Furthermore, the middle stay 84 is positioned lower than the upper support portion 72 of the reinforcing member 70. The front end stay 83 is positioned lower than the lower support portion 73 of the reinforcing member 70. This allows the reinforcing member 70 to support the muffler 82 over a wider range.

[0052] Furthermore, the front end stay 83 is lower than the intermediate stay 84. Therefore, the muffler 82 can be easily supported by the reinforcing member 70 at a position along the pivot frame 32, and the reinforcing member 70 can be shaped to fit the pivot frame 32.

[0053] FIG. 9 is a perspective view of the CBS mechanism 100 and its surroundings as viewed from the inside in the vehicle width direction. The CBS mechanism 100 is disposed below the pivot shaft 22 in a side view of the vehicle body. The CBS mechanism 100 is disposed between the pivot frame 32 and the reinforcing member 70. The CBS mechanism 100 is disposed on the outer side in the vehicle width direction of the right side surface portion 32b of the pivot frame 32.

[0054] The CBS mechanism 100 has an equalizer 110. The equalizer 110 is disposed on the side of the pivot frame 32, between the pivot shaft 22 and the stand pivot shaft 54. The equalizer 110 has a first equalizer link 111 supported by the swing plate portion 53c of the brake pedal 53, and a second equalizer link 112 swingably supported by the first equalizer link 111.

[0055] The first equalizer link 111 is composed of a pair of left and right plate-like members 113, 114 extending in the vertical direction. The first equalizer link 111 is supported at its vertical middle portion by a connecting pin 121 extending in the vehicle width direction. The connecting pin 121 is supported by the swing plate portion 53c of the brake pedal 53. The first equalizer link 111 is swingably supported by the swing plate portion 53c.

[0056] The first equalizer link 111 has a rear brake rod support portion 111a above the connecting pin 121. The first equalizer link 111 has a second equalizer link support portion 111b below the connecting pin 121. A connecting pin 122 extending in the vehicle width direction is supported on the second equalizer link support portion 111b. The second equalizer link 112 is swingably supported on the second equalizer link support portion 111b via the connecting pin 122.

[0057] The second equalizer link 112 has a block shape with three apexes. In other words, the second equalizer link 112 of this embodiment is generally L-shaped in a side view of the vehicle body. The second equalizer link 112 has a link connection portion (first apex) 112a connected to the first equalizer link 111, a cable connection portion (third apex) 112c that swingably supports the front-wheel interlocking brake cable 67, and a rod connection portion (second apex) 112b provided between the link connection portion 112a and the cable connection portion 112c. The cable connection portion 112c is located below the connecting pin 121 of the brake pedal 53.

[0058] A connecting pin 123 extending in the vehicle width direction is supported on the rod connecting portion 112b. A front end (one end in the front-rear direction) of a link rod 115 extending in the front-rear direction is swingably supported on the connecting pin 123. The link rod 115 is one of the members for setting the swing characteristics of the first equalizer link 111 and the second equalizer link 112. The rear end (the other end in the front-rear direction) of the link rod 115 is rotatably connected to the support pin 78 (see FIG. 7) of the reinforcing member 70. Thus, the link rod 115 is supported by the pivot frame 32, which is the vehicle body frame 11, via the reinforcing member 70.

[0059] A delay spring 120 is connected to an upper portion of the second equalizer link 112. The delay spring 120 is a coil-shaped tension spring. In this embodiment, one end of the delay spring 120 is hooked onto a connecting pin 122 to which the second equalizer link 112 is connected. The other end of the delay spring 120 is hooked onto the spring engaging portion 79b of the reinforcing member 70. As a result, the delay spring 120 biases the first equalizer link 111 in a clockwise direction around the connecting pin 121 when viewed from the right side of the vehicle body (see FIG. 7). The delay spring 120 delays the timing at which the equalizer 110 pulls the front-wheel-interlocking brake cable 67 when the brake pedal 53 is operated.

[0060] The rear brake rod 66 is swingably supported on the rear brake rod support portion 111a of the first equalizer link 111 via a connecting pin 124 extending in the vehicle width direction. A swinging member 131 is swingably connected to the cable connecting portion 112c of the second equalizer link 112 via a connecting pin 125. The front-wheel-interlocked brake cable 67 is connected to the swinging member 131. More specifically, the front-wheel-interlocked brake cable 67 is connected from above. An outer cable 67a of the front-wheel-interlocked brake cable 67 is supported by a bracket 69 that supports the brake switch 60. An inner cable 67b of the front-wheel-interlocked brake cable 67 is led downward from the outer cable 67a and is swingably connected to the second equalizer link 112 via the swinging member 131.

[0061] Since the outer cable 67a of the front wheel interlocking brake cable 67 and the brake switch 60 are supported by the bracket 69, it is easy to consolidate and arrange the CBS mechanism 100 and the brake switch 60, which are linked to the operation of the brake pedal 53, and it is easy to arrange the CBS mechanism 100 compactly.

[0062] The reinforcing member support portion 32e is located at the end of the movable range of the second equalizer link 112. Therefore, the reinforcing member support portion 32e, which is tubular and long in the vehicle width direction, can function as a stopper for the equalizer 110.

[0063] In the CBS mechanism 100, the front-wheel interlocking brake cable 67 is operated in the vertical direction, so the CBS mechanism 100 can easily be configured to extend in the vertical direction. Here, the CBS mechanism 100 is located more inward in the vehicle width direction than the pivot portion 16e of the swing arm 16. More specifically, the CBS mechanism 100 is disposed more inward in the vehicle width direction than the left-right width center L3 of the right pivot portion (connection portion) 16e of the swing arm 16. Because the CBS mechanism 100 is disposed more inward in the vehicle width direction, it is easy to dispose the reinforcing member 70 closer to the vehicle width direction, making it easier to prevent the reinforcing member 70 from protruding in the vehicle width direction.

[0064] Figure 10 is a diagram illustrating the operation of the CBS mechanism 100 when the brake pedal 53 is in the normal position. Figure 11 is a diagram illustrating the operation of the CBS mechanism 100 when the brake pedal 53 begins to be operated. Figure 12 is a diagram illustrating the operation of the CBS mechanism 100 when the brake pedal 53 moves to the operating position. The CBS mechanism 100 is configured so that when the brake pedal 53 is operated, the equalizer 110 moves while maintaining various balances.

[0065] That is, when the brake pedal 53 is operated, the connecting pin 121 supported by the brake pedal 53 moves forward. Therefore, the first equalizer link 111 of the equalizer 110 tends to move forward together with the connecting pin 121 as a whole, as seen from the right side of the vehicle body. At this time, the second equalizer link support portion 111b on the lower side of the first equalizer link 111 is urged rearward by the delay spring 120, so the first equalizer link 111 rotates counterclockwise around the connecting pin 121, as shown in FIG. 11 . Therefore, in the first equalizer link 111, the rear brake rod support portion 111a above the connecting pin 121 moves forward. That is, the rear brake rod 66 moves forward, and the rear wheel brake 64 is actuated.

[0066] When the brake pedal 53 is further operated, the swing plate portion 53c moves forward, and the entire first equalizer link 111 moves forward. That is, the first equalizer link 111 moves forward against the elastic force of the delay spring 120. At this time, the second equalizer link 112 attempts to move forward while being connected to the link rod 115, and therefore, the second equalizer link 112 rotates clockwise with respect to the connecting pin 123 in FIG. 12 .

[0067] Therefore, the cable connecting portion 112c of the second equalizer link 112 moves downward, and the inner cable 67b of the front wheel interlocking brake cable 67 is pulled downward. As the inner cable 67b is pulled, the brake arm 61b (see FIG. 1) of the front wheel brake 61 rotates, and the front wheel brake 61 is also actuated. When the brake pedal 53 is released, the brake pedal 53 returns to its normal position (see FIGS. 1 and 10) due to the biasing force of the return spring 58 or the like.

[0068] The ratio between the braking force of the front wheel brake 61 and the braking force of the rear wheel brake 64 is set to an appropriate ratio by the equalizer 110. The shape and structure of each part of the CBS mechanism 100 and the positions of each connecting pin 121 to 125 may be changed as appropriate.

[0069] In this embodiment, by disposing the CBS mechanism 100 below the pivot shaft 22, the CBS mechanism 100 can be retracted from the swing arm 16. Therefore, it is possible to provide a saddle-ride type vehicle 10 in which the CBS mechanism 100 is compactly disposed so that the cross portion 16c of the swing arm 16 can be easily brought close to the pivot shaft 22. Therefore, even in a saddle-ride type vehicle 10 in which the CBS mechanism 100 cannot be disposed between the pair of left and right swing arms 16, the CBS mechanism 100 can be disposed compactly.

[0070] In particular, in this embodiment, the equalizer 110 is composed of a first equalizer link 111 and a second equalizer link 112, which makes it easier to optimize the movable range of the equalizer 110 to the space below the pivot shaft 22, making it easier to make the installation space for the CBS mechanism 100 compact.

[0071] As described above, according to this embodiment to which the present invention is applied, in the saddle-ride type vehicle 10 that includes the pivot frame 32 that supports the swing arm 16 so that it can swing, and the muffler 82 that extends rearward past the side of the pivot frame 32, the pivot frame 32 is provided with a reinforcing member 70 that extends parallel to the pivot frame 32, and the muffler 82 is supported by the pivot frame 32 via the reinforcing member 70. According to this configuration, by attaching the muffler 82 via the reinforcing member 70, the muffler 82 can be easily attached and detached. Furthermore, the support portion of the muffler 82 only needs to be of a size that allows it to be attached to the reinforcing member 70, which makes it easier to ensure the support strength and support rigidity of the muffler 82 while preventing the support portion of the muffler 82 from becoming too large. Therefore, it is possible to provide a saddle-ride type vehicle 10 in which the muffler 82 is easily attached and detached, and in which the support strength and support rigidity of the muffler 82 can be easily ensured while preventing the support portion of the muffler 82 from becoming too large.

[0072] In this embodiment, the reinforcing member 70 is supported by the pivot frame 32 at at least two locations, an upper support portion 72 and a lower support portion 73, with the upper support portion 72 being located above the upper surface of the muffler 82 and the lower support portion 73 being located below the lower surface of the muffler 82. According to this configuration, the reinforcing member 70 is supported by the pivot frame 32 at a position that is vertically spaced apart from the muffler 82, making it easier to stably support the muffler 82 with the reinforcing member 70, and making it easier to ensure the support strength and support rigidity of the muffler 82.

[0073] In this embodiment, the upper support portion 72 is supported by the pivot shaft 22 . According to this configuration, the pivot shaft 22, which is firmly supported and extends in the vehicle width direction, can be used to ensure the support strength and support rigidity of the reinforcing member 70. This also makes it easier to ensure the support strength and support rigidity of the muffler attached to the reinforcing member.

[0074] Furthermore, in this embodiment, the muffler 82 is supported by the reinforcing member 70 at least at two points, the front end stay 83 and the intermediate stay 84, and the front end stay 83 is located forward of the straight line L1 connecting the upper support portion 72 and the lower support portion 73 of the reinforcing member 70 when viewed from the side of the vehicle body, and the intermediate stay 84 is located rearward of the straight line L1 when viewed from the side of the vehicle body. According to this configuration, by distributing the muffler 82 to the front and rear of the support portion of the reinforcing member 70 and supporting it on the reinforcing member 70, it is possible to suppress the concentration of stress acting on the reinforcing member 70 from the muffler 82, and also to make it easier to absorb vibrations of the muffler 82 by utilizing the flexibility of the front and rear portions of the reinforcing member 70 that are away from the support portion.

[0075] In addition, in this embodiment, the front end stay 83 and the middle stay 84 are arranged with a difference in height, and the higher of the front end stay 83 and the middle stay 84 is located below the upper support portion 72 of the reinforcing member 70, and the lower of the front end stay 83 and the middle stay 84 is located below the lower support portion 73 of the reinforcing member 70. According to this configuration, the muffler 82 can be supported by the reinforcing member 70 over a wider area, making it easier to ensure the support strength and support rigidity of the muffler 82 while preventing the support portion of the muffler 82 from becoming larger.

[0076] In this embodiment, the front end stay 83 is lower than the intermediate stay 84 . According to this configuration, the front portion of the muffler 82 can be easily supported from below, and the support strength and support rigidity of the rear-rising muffler 82 can be easily ensured.

[0077] In this embodiment, a CBS mechanism 100 is housed between the pivot frame 32 and the reinforcing member 70. According to this configuration, the space between the pivot frame 32 and the reinforcing member 70 can be effectively utilized, and the CBS mechanism 100 can be protected by the reinforcing member 70.

[0078] [Other embodiments] The above-described embodiment merely shows one aspect of the present invention, and any modifications and applications are possible without departing from the spirit of the present invention.

[0079] In the above embodiment, the saddle-ride type vehicle 10 is exemplified as a saddle-ride type vehicle 10 having a power unit 12 as an internal combustion engine, but is not limited to this. For example, the saddle-ride type vehicle 10 may be a vehicle that does not have a power unit 12 as an internal combustion engine, i.e., an electric vehicle. Therefore, in the above embodiment, the power unit 12 is exemplified as a power unit that drives the vehicle body, but the power unit may also be a power unit that has an electric motor for driving. In this case, the saddle-ride type vehicle as an electric vehicle is provided with a battery for driving the power unit instead of the fuel tank 29.

[0080] In the above embodiment, the pivot frame 32 is formed in a bent plate shape and fixed to the rear end of the main frame 31, but the shape of the pivot frame 32 is not limited to this. For example, the pivot frame 32 may be formed so as to extend continuously from the main frame 31 and be integral with the main frame 31 in appearance.

[0081] In the above embodiment, the second equalizer link 112 has been described as being substantially L-shaped, but any shape having three peaks may be used. Therefore, the second equalizer link 112 may be triangular, rectangular, or the like.

[0082] In the above embodiment, it is preferable that the equalizer 110 has the first equalizer link 111 and the second equalizer link 112, as this makes it easier to move the equalizer 110 according to the installation space, but the equalizer 110 may also be composed of a single link component.

[0083] In the above embodiment, it is preferable that the equalizer 110 has the first equalizer link 111 and the second equalizer link 112, as this makes it easier to move the equalizer 110 according to the installation space, but the equalizer 110 may also be composed of a single link component.

[0084] In the above embodiment, the configuration in which the front end stay 83 is located below the intermediate stay 84 has been described, but the front end stay 83 may be located above the intermediate stay 84 .

[0085] In the above embodiment, a motorcycle having a front wheel 13 and a rear wheel 15 has been used as an example of the saddle-ride vehicle 10, but the present invention is not limited to this, and can be applied to a three-wheel saddle-ride vehicle having two front or two rear wheels, or a saddle-ride vehicle having four or more wheels.
