The rear ends of the rear sub-stands 39 are connected to the front-rear direction intermediate portions of the seat stands 38 (see Figure 1 ).

[0069] The main frame 31, seat frame 38, and rear subframe 39, when viewed from the side of the vehicle body, form a closed loop-shaped space (closed loop shape part) S1. When viewed from the side of the vehicle body, the closed loop-shaped space S1 is an inverted triangle shape. Figure 3 As shown, a battery box (battery storage component) 41 is arranged in a closed loop-shaped space S1. The battery box 41 is positioned on the right side (one side in the vehicle width direction) relative to the center of the vehicle body. A battery 42 is housed in the battery box 41. The battery 42 is connected to the main wiring harness 48. An air filter box 43 (see reference) is arranged on the left side of the battery box 41 (the other side in the vehicle width direction). Figure 15 ).

[0070] The closed loop shape space S1 is covered by the side cover 40 from the outside in the vehicle width direction (see reference). Figure 1 , Figure 2 When viewed from the side of the vehicle body, the side cover 40 is larger than the closed loop shape space S1. The closed loop shape space S1 is covered by the side cover 40 from the outside in the vehicle width direction, and therefore is a space that cannot be seen from the outside when viewed from the side of the vehicle body.

[0071] like Figure 1 As shown, an exhaust pipe 25a is connected to the front of the cylinder head 24. The exhaust pipe 25a extends downward in front of the cylinder head 24 and then extends rearward below the power unit 12. An exhaust muffler 25b is connected to the rear end of the exhaust pipe 25a. The exhaust pipe 25a and the exhaust muffler 25b constitute the exhaust system 25. A foot pedal 23p is positioned on the right side of the crankcase 23 and above the pedal 28.

[0072] The saddle-type vehicle 10 includes a front wheel brake 51 for braking the front wheels 13 and a rear wheel brake 52 for braking the rear wheels 15. The front wheel brake 51 is connected to a brake lever 21r via a front wheel brake cable 51a, which functions as a first front wheel braking force transmission component. The brake lever 21r is located on the right side of the handle 21 and functions as a front wheel brake operating component operated by the occupant (driver). When the brake lever 21r is operated by the occupant, the front wheel brake 51 is activated, applying braking force to the front wheels 13.

[0073] The front wheel brake 51 is a disc brake, a type of hydraulic brake. Therefore, in this embodiment, a master cylinder that generates hydraulic pressure corresponding to the braking operation is provided, and a hydraulic hose is used in the front wheel brake cable 51a. The front wheel brake 51 is not limited to a disc brake, and may be a braking device other than a disc brake, such as a drum brake.

[0074] The rear wheel brake 52 is connected to the brake pedal 53 via a brake lever 52a, which functions as a rear wheel braking force transmission component. The brake pedal 53 is located around the right-side pedal 28. The brake pedal 53 functions as a rear wheel brake operating component operated by the occupant's foot. Figure 3 As shown, the rear of the brake pedal 53 is supported by a shaft 53a extending in the vehicle width direction, allowing it to swing. The brake pedal 53 is supported so that it can be in its normal position when not in braking operation (see reference). Figure 3 (The solid line) and the operating position of the braking operation state (refer to) Figure 3 The brake pedal 53 swings between the double-dotted lines. When the brake pedal 53 is operated by the occupant, the rear wheel brake 52 is engaged, applying braking force to the rear wheels 15.

[0075] The rear wheel brake 52 is a drum brake, which is a type of mechanical brake. The rear wheel brake 52 is not limited to a drum brake, and may be a braking device other than a drum brake. In addition, the brake lever 52a may be replaced with a brake cable or the like, which can be used as a rear wheel braking force transmission component.

[0076] The saddle-type vehicle 10 of this structure is equipped with a CBS mechanism 61 (see reference) that activates both the front wheel brake 51 and the rear wheel brake 52 via the operation of the brake pedal 53. Figure 12 ).

[0077] Figure 5 It is the right side of battery box 41. Figure 6 This is a 3D view of the battery box 41 viewed from the right front. Figure 7 This is a 3D view of the battery box 41 viewed from the right rear.

[0078] The battery box 41 is supported on the vehicle frame 11. The battery box 41 has a container-shaped battery housing portion 81 that is recessed from the outer side in the vehicle width direction to the inner side in the vehicle width direction, a wiring harness support portion 82 formed at the rear of the battery housing portion 81, and a lower wall portion 83 formed below the battery housing portion 81.

[0079] The battery housing 81 has an inner wall portion 81a that is generally rectangular when viewed from the side of the vehicle body. A front wall portion 81b, an upper wall portion 81c, a lower wall portion (bottom surface) 81d, and a rear wall portion 81e, all protruding outwards in the vehicle width direction relative to the inner wall portion 81a, are formed on the outer periphery of the inner wall portion 81a. Thus, the battery housing 81 has a shape that is open outwards in the vehicle width direction.

[0080] A bracket engagement hole 81e1 of a shape recessed toward the inner side in the vehicle width direction is formed at the lower end portion of the rear wall portion 81e. The rear end portion of the battery bracket 90 is engaged with the bracket engagement hole 81e1. A bracket fixing portion 81b1 is formed at the upper portion of the front wall portion 81b. The front end portion of the battery bracket 90 is fixed to the bracket fixing portion 81b1 by a fixing member. Thus, the battery 44 is maintained in a state of being housed in the battery housing portion 81 in a state of being restrained by the battery bracket 90.

[0081] A wire harness support portion 82 is formed at the rear portion of the battery housing portion 81. The wire harness support portion 82 has an upper wall portion 82a extending rearward from the upper wall portion 81c of the battery housing portion 81. In addition, the wire harness support portion 82 has a lower wall portion 82c extending rearward and upward from the lower wall portion 81d of the battery housing portion 81. The lower wall portion 82c is inclined along the rear sub frame 39. Further, the wire harness support portion 82 has a rear wall portion 82b connecting between the rear end of the upper wall portion 82a and the rear end of the lower wall portion 82c.

[0082] A case lower wall portion (battery housing member lower wall portion) 83 extending downward is formed at the lower wall portion 81d of the battery housing portion 81.

[0083] The case lower wall portion 83 has an inner side plate 84 formed at the inner surface side, an outer side plate 85 formed so as to oppose the inner side plate 84, and a rear side plate 86 connecting between the rear end of the inner side plate 84 and the rear end of the outer side plate 85.

[0084] The inner side plate 84 is a flat plate shape having a thickness in the vehicle width direction and extending downward. The inner side plate 84 extends downward from the vehicle width direction inner end of the lower wall portion 81d (refer to Figure 13 ). The inner side plate 84 is formed with a front edge 84a, a front side lower edge 84b extending rearward and downward from the lower end of the front edge 84a, a rear side lower edge 84c extending rearward and upward from the rear end of the front side lower edge 84b, and a rear edge extending upward from the rear end of the rear side lower edge 84c.

[0085] The outer side plate 85 is a flat plate shape having a thickness in the vehicle width direction and extending downward. The outer side plate 85 extends downward from the vehicle width direction central portion of the lower wall portion 81d (refer to Figure 13 ). The outer side plate 85 is formed with a front edge 85a extending downward, a front side lower edge 85b extending rearward and downward from the lower end of the front edge 85a, a rear side lower edge 85c extending rearward and upward from the rear end of the front side lower edge 85b, and a rear edge 85d extending upward from the rear end of the rear side lower edge 85c. The outer side plate 85 is formed with a cover fixing portion 85e projecting in a stepped shape toward the outer side in the vehicle width direction.

[0086] The rear side plate 86 is formed with an inner edge 86a connected to the rear edge of the inner side plate 84, an outer edge 86c connected to the rear edge 85d of the outer side plate 85, and a lower edge 86b connecting the lower end of the inner edge 86a and the lower end of the outer edge 86c. The lower edge 86b is inclined linearly upward as it advances outward in the vehicle width direction.

[0087] Therefore, a CBS protection space S2 is formed by a space surrounded by the lower wall portion 81d, the inner side plate 84, the outer side plate 85, and the rear side plate 86. The CBS protection space S2 communicates with the outside via a reverse U-shaped opening S2a when viewed from the front (see FIG. 6). Figure 11 In addition, the CBS protection space S2 communicates with the outside through a square-shaped cutout-shaped opening S2b when viewed from the back.

[0088] In the battery case 41, a seat bracket fixing piece 87 protruding upward from the upper wall portion 81c is formed at the upper portion of the battery housing portion 81. In addition, a rear sub-frame fixing portion 88 is formed at the front lower portion of the wire harness support portion 82. Further, a protruding piece 89 protruding rearward is formed at the rear end portion of the wire harness support portion 82.

[0089] Figure 8 is a right side view of the rear fender 27. Figure 9 is a perspective view of the rear fender 27 viewed from the right rear.

[0090] The rear fender 27 has a fender front portion 91 extending rearward and upward. A recessed portion 91a recessed upward corresponding to the shape of the upper portion of the rear wheel 15 is formed in the fender front portion 91. A fender rear portion 92 extending rearward is formed rearward of the fender front portion 91.

[0091] The fender rear portion 92 has a columnar rearward extending portion 92a extending rearward and a plate-shaped lower extending portion 92b extending rearward and downward from the rear end of the rearward extending portion 92a. A tail lamp fixing portion 92c (see FIG. 6) is formed at the rear end of the rearward extending portion 92a. Rear turn signal lamp fixing portions 92d are formed on both sides in the vehicle width direction of the tail lamp fixing portion 92c. Figure 9

[0092] Here, a fender lower wall portion (rear fender lower wall portion) 93 extending downward is formed at the front end of the fender front portion 91. The fender lower wall portion 93 is formed on the right side. The fender lower wall portion 93 is formed in a cross-section L shape. That is, the fender lower wall portion 93 has a side wall 93a directed outward in the vehicle width direction and a front wall 93b connected to the rear end of the side wall 93a and directed forward in the vehicle body.

[0093] Figure 10 is a front view showing the vehicle frame 11, the battery case 41, and the CBS mechanism 61. Figure 11 ​is a bottom view showing the vehicle frame 11, the battery case 41, and the CBS mechanism 61.

[0094] As shown in Figure 4 , the battery case 41 is supported by the vehicle frame 11. The battery case 41 is disposed inside the closed loop-shaped space S1. Specifically, a seat frame fixing piece 87 of the battery case 41 is fixed at the vehicle width direction outer side of the right seat frame 38. Further, a rear sub-frame fixing portion 88 is fixed at the vehicle width direction inner side of the strut 39a (see Figure 3 ) of the rear sub-frame 39.

[0095] At this time, the upper wall portion 82a of the wire harness support portion 82 of the battery case 41 is positioned below the right seat frame 38. The battery case 41 overlaps the right seat frame 38 when viewed from the vehicle body floor (see Figure 11 ). Further, the protruding piece 89 is positioned at a position further outward in the vehicle body width direction than the rear frame 20 (see Figure 3 ). The lower wall portion 82c of the wire harness support portion 82 extends along the rear sub-frame 39. Thus, the battery case 41 is positioned inside the closed loop-shaped space S1.

[0096] The rear fender 27 is supported at the rear of the battery case 41. The rear fender 27 is fixed in a manner that straddles the left and right pair of seat frames 38. The rear fender 27 is disposed along the rear sub-frame 39. At this time, the fender lower wall portion 93 of the rear fender 27 protrudes downward further than the rear sub-frame 39 (see Figure 2 , Figure 3 ). Further, the fender lower wall portion 93 is disposed in a manner that covers the case lower wall portion 83 of the battery case 41 (see Figure 11 ). That is, the side wall 93a of the fender lower wall portion 93 covers the inner side plate 84 of the case lower wall portion 83 from the vehicle width direction inner side. Further, the front wall 93b of the fender lower wall portion 93 covers the rear side plate 86 of the case lower wall portion 83 from the rear. Thus, the cutout-shaped opening S2b of the CBS protection space S2 is covered from the rear by the fender lower wall portion 93.

[0097] Figure 12 is a perspective view showing the CBS mechanism 61 as viewed from the right rear. Figure 12 is a perspective view showing the main portion of the CBS mechanism 61 as viewed from the right upper. Figure 12 shows a state in which the region corresponding to the brake pedal 53 is cut off.

[0098] At least a portion of the CBS mechanism 61 is disposed in the CBS protection space S2 of the case lower wall portion 83. In the present embodiment, the swing arm 16 widens outward in the vehicle width direction as it goes toward the rear of the vehicle (see Figure 12 ). Thus, at least a portion of the balancer 63 is substantially disposed above the swing arm 16 (corresponding to a position overlapping in the vertical direction when viewed in the vehicle front-rear direction).

[0099] The CBS mechanism 61 has an equalizer 63 arranged in the up-and-down direction, a CBS cable 64 extending forward from an upper end portion of the equalizer 63, and a force applying member 66 connected to the equalizer 63 and applying a force to the equalizer 63 to a side where the front wheel brake 51 and the rear wheel brake 52 are not operated.

[0100] The equalizer 63 has a first link plate 71 on the lower side linked to the rear upper end portion of the brake pedal 53 and a second link plate 72 on the upper side linked to the first link plate 71.

[0101] The first link plate 71 is formed of one plate-shaped member extending in the up-and-down direction. The first link plate 71 integrally has an extension portion 71a extending in the up-and-down direction, an intermediate portion 71c extending upward from an upper end of the extension portion 71a to the inner side in the vehicle width direction, and a deviation portion 71b extending upward from an upper end of the intermediate portion 71c. The intermediate portion 71c is inclined to the inner side in the vehicle width direction as it advances upward.

[0102] The deviation portion 71b is deviated to the inner side in the vehicle width direction with respect to the extension portion 71a. The deviation portion 71b is parallel to the extension portion 71a. The deviation portion 71b extends in the vertical direction. In addition, the deviation portion 71b can not be parallel to the extension portion 71a, and can be appropriately changed in shape.

[0103] The second link plate 72 is formed of one plate-shaped member extending in the up-and-down direction. The second link plate 72 is rotatably linked to the first link plate 71 via a link pin 62b extending in the vehicle width direction.

[0104] A link rod 65 extending in the front-and-rear direction is linked to the upper-and-lower intermediate portion of the second link plate 72. A rear end (one end in the front-and-rear direction) of the link rod 65 is linked via a link pin 62c extending in the vehicle width direction. The link rod 65 is one of members for setting the swing characteristics of the first link plate 71 and the second link plate 72. A front end (the other end in the front-and-rear direction) of the link rod 65 is rotatably linked to a strut 47. The strut 47 is a member of metal or the like having rigidity extending rearward from the upper side cross member 35.

[0105] The first link plate 71, the second link plate 72, and the link rod 65 are made of one plate member of metal or the like having rigidity. For example, the first link plate 71, the second link plate 72, and the link rod 65 are made by bending a plate-shaped plate member, or are made by mold forming, and are processed for hole processing for mounting the link pins 62a to 62c. However, the configuration, shape, and manufacturing method, and the like related to the first link plate 71, the second link plate 72, and the link rod 65 can be appropriately changed.

[0106] A force applying member 66 is connected to the upper portion of the second link plate 72. In the present embodiment, the force applying member 66 is a coil-shaped extension spring. One end of the force applying member 66 is attached to the upper portion of the second link plate 72. The other end of the force applying member 66 is hooked to the hooking portion 47a of the strut 47 and is connected thereto. Thus, the force applying member 66 exerts a force to the second link plate 72 in the clockwise direction when viewed from the right side surface of the vehicle body (see FIG. 6). Figure 3 The force applying member 66 of the present embodiment is an extension spring, but it can be a force applying member other than an extension spring.

[0107] In the first link plate 71, the brake pedal 53 is connected to the upper end portion of the extension portion 71a via a connecting pin 62a extending in the vehicle width direction. In addition, the front end of the brake lever 52a extending from the rear wheel brake 52 is connected to the lower end portion of the extension portion 71a on the lower side than the connecting pin 62a.

[0108] In the second link plate 72, one end of the CBS cable 64 functioning as a second front wheel brake force transmission member is connected to the upper portion on the upper side than the connecting pin 62c. Specifically, the outer cable 64b of the CBS cable 64 is supported to the cable support portion 47b provided to the strut 47. Further, the inner cable 64a led to the rearward direction from the outer cable 64b is connected to the second link plate 72. The other end of the CBS cable 64 is connected to the front wheel brake 51. More specifically, the other end of the CBS cable 64 is connected to the master cylinder generating hydraulic pressure for the front wheel brake 51.

[0109] The CBS mechanism 61 is configured such that the equalizer 63 moves while achieving various balances in the case where the brake pedal 53 is operated.

[0110] That is, when the brake pedal 53 is operated, the connecting pin 62a supported by the brake pedal 53 moves to the front. Thus, when viewed from the right side surface of the vehicle body, the first link plate 71 of the equalizer 63 moves to the front as a whole together with the connecting pin 62a. In addition, the first link plate 71 rotates in the counterclockwise direction with the connecting pin 62a as a reference. Thus, the lower end portion of the first link plate 71 moves to the front, and the brake lever 52a connected to the lower end portion is pulled to the front. Thus, the rear wheel brake 52 is operated via the brake lever 52a.

[0111] At this time, the entire first link plate 71 moves forward, and the first link plate 71 is intended to move forward with respect to the link pin 62c of the second link plate 72. Therefore, the lower end portion of the second link plate 72 of the equalizer 63 also moves forward with respect to the link pin 62c, and the second link plate 72 rotates counterclockwise with the link pin 62c as a reference. Therefore, the upper end portion of the second link plate 72 moves backward, and the CBS cable 64 linked to the upper end portion of the second link plate 72 is pulled backward. Therefore, the master cylinder is operated via the CBS cable 64, and the front wheel brake 51 operates.

[0112] When the operation of the brake pedal 53 is released, the brake pedal 53 returns to the normal position (solid line) by the action of the urging member 66 or the like. Figure 2

[0113] Further, the ratio of the brake force of the front wheel brake 51 to the brake force of the rear wheel brake 52 or the like is set to an appropriate ratio or the like by the equalizer 63. In addition, the shape and configuration of each portion of the CBS mechanism 61, and the positions of each link pin 62a to 62c or the like can also be appropriately changed.

Figure 14 is a view that shows a main portion of the cross section of the XIV-XIV line of Figure 3 . Figure 15 is a view that shows a main portion of the cross section of the XV-XV line of Figure 3 . Figure 16 is a view that shows a main portion of the cross section of the XVI-XVI line of Figure 3 .

[0115] When viewed from the side of the vehicle body (refer to Figure 2 , Figure 3 ), the brace 47 enters the inside of the CBS protection space S2 (refer to Figure 3 ). In addition, the second link plate 72 of the equalizer 63 enters the inside of the CBS protection space S2 (refer to Figure 3 ). The urging member 66 that is a part of the CBS mechanism 61 is always disposed in the inside of the CBS protection space S2. They are covered by the side cover 40.

[0116] When viewed from the front of the vehicle body (refer to Figure 10 ), the second link plate 72 of the equalizer 63, the CBS cable 64, and the urging member 66 overlap the upper side beam portion 35. In addition, when viewed from the front of the vehicle body (refer to Figure 13 ), the first link plate 71 of the equalizer 63 overlaps the pivot 22.
