  A fuel tank stay 252 that supports the fuel tank 31 is provided at a position between the front end portion of the seat rail 25 and the welded portion of the side tube 26. As shown in FIG. 6, air cleaner brackets 253 and 254 for fixing the upper portion of the air cleaner 10 are provided on the left front and right rear of the fuel tank stay 252, respectively. The air cleaner bracket 253 is formed integrally with the fuel tank stay 252.

  The inclination angle of the front portion 21 a of the main tube 21 is gentler than the inclination angle of the front portion 24 a of the down tube 24. A space having a substantially quadrilateral shape in side view is formed so that the main tube 21 and the down tube 24 are sandwiched between the upper and lower sides. In addition, a space having a substantially triangular shape in side view is formed behind the space having a substantially quadrilateral shape in side view so as to be surrounded by the rear portion 21b of the main tube 21, the seat rail 25, and the side tube 26.

  The engine 8 is suspended in a space having a substantially quadrilateral shape when viewed from the side by the main tube 21 and the down tube 24. The engine 8 is supported by the vehicle body frame 2 via engine suspension plates 81 (81L, 81R), 82 (82L, 82R) and the like. The engine suspension plate 81 (81L, 81R) is fixed to the front portion 24a of the down tube 24, and the engine suspension plate 82 (82L, 82R) is a reinforcement provided between the main tube 21 and the down tube 24. 28 is fixed.

  An air cleaner 10 is installed in a space that is surrounded by the rear portion 21 b of the main tube 21, the seat rail 25, and the side tube 26 and has a substantially triangular shape when viewed from the side. That is, the air cleaner 10 is disposed on the rear upper side of the engine 8. As shown in FIGS. 2 and 3 (see also FIGS. 7 to 9, etc.), the front left side of the air cleaner 10 is bulged forward so as to avoid the main tube 21. It overlaps with the main tube 21. The air cleaner 10 is connected to the engine 8 via a fuel supply device 11 and an intake pipe 83 at a part on the left front side. As a result, an air-fuel mixture of air from the air cleaner 10 and fuel from the fuel supply device 11 is supplied to the engine 8.

  As shown in FIG. 2, on the right side of the air cleaner 10, a battery 12 that supplies electric power to electrical components mounted on the motorcycle 1 is installed. The battery 12 has a substantially rectangular parallelepiped outer shape, and is held by a battery holding portion 101 (not shown in FIGS. 2 to 6, see FIG. 8) formed on the right side surface of the air cleaner 10. The battery 12 is held by the battery holding unit 101 so that a part of the front thereof overlaps the main tube 21 in a side view. The battery 12 and the left front portion that bulges out in the air cleaner 10 are arranged so as to sandwich the main tube 21 in the vehicle width direction.

  A CDI (Capacitor Discharge Ignition) unit (electrical component, control unit) 121 that controls combustion of the engine 8 and a starter relay (electrical component) 122 that controls starting of the engine 8 are installed on the right side of the rear portion of the battery 12. Yes. The CDI unit 121 and the starter relay 122 are provided on the right side of the right side surface of the battery 12 in the vehicle width direction. The front of the CDI unit 121 and the starter relay 122 is a space through which the right foot of the driver passes.

  By the way, when a battery holding portion is formed on the side surface of an air cleaner in a backbone type motorcycle to hold the battery, the arrangement position of the battery is restricted due to the shape of the air cleaner. If the battery cannot be brought sufficiently close to the engine due to the restriction of the arrangement position, the moment of inertia around the center of gravity of the motorcycle cannot be kept small, and high exercise performance cannot be secured. Therefore, in the motorcycle 1 of the present embodiment, the air cleaner 10 is configured so that the battery 12 can be positioned near the engine 8.

  Details of the air cleaner 10 will be described with reference to FIGS. 7 and 8. FIG. 7 is a perspective view showing a structure around the air cleaner 10, and FIG. 8 is a perspective view showing a structure of the air cleaner 10. 7 and 8, the front of the vehicle body is indicated by an arrow F, and the left and right sides of the vehicle body are indicated by arrows L and R, respectively.

  As shown in FIG. 8, the air cleaner 10 includes an air cleaner case 10R and an air cleaner cover 10L attached to the left side of the air cleaner case 10R, and has a substantially rectangular parallelepiped outer shape. Inside the air cleaner 10, a filter element (not shown) that collects dust in the atmosphere is disposed so that clean air can be supplied to the engine 8.

  The right side surface of the air cleaner case 10R is formed with a front support portion 102, a rear support portion 103, and a lower support portion 104 that protrude rightward at the front upper side, the rear side, and the lower side, respectively. The unit 101 is configured. The substantially rectangular parallelepiped battery 12 held by the battery holding unit 101 is supported on the front surface, the rear surface, and the bottom surface by the front support portion 102, the rear support portion 103, and the lower support portion 104, respectively. The battery holding unit 101 provides high restraint and can hold the battery 12 in a predetermined position. Battery holder support portions 102 a and 103 a are respectively provided on the right side surface of the front support portion 102 and the lower portion of the right side surface of the rear support portion 103. A battery holder 123 that restricts the movement of the battery 12 is fixed to the battery holder support portions 102a and 103a.

  The battery holder 123 is configured by bending a plate-like member, and the front portion of the right plate portion 123a that extends obliquely up and down with respect to the longitudinal direction of the vehicle body is bent leftward to become the front plate portion 123b. The rear part of the part 123a is bent to the left to form a rear plate part 123c. That is, the plate portion 123b and the rear plate portion 123c are each extended leftward from the right plate portion 123a. Fixing portions 123d and 123e that are fixed to the battery holder support portions 102a and 103a are provided at the front end portions of the front plate portion 123b and the rear plate portion 123c, respectively. In a state where the battery holder 123 is fixed to the air cleaner case 10R, the right side surface, the front surface, and the rear surface of the battery 12 are pressed by the right plate portion 123a, the front plate portion 123b, and the rear plate portion 123c of the battery holder 123, respectively. Thereby, the movement of the battery 12 in the front-rear and left-right directions is restricted.

  In the battery holder 123, the right plate portion 123a has a front-up shape in which the front side (front plate portion 123b side) is positioned higher than the rear side (rear plate portion 123c side). For this reason, the battery 12 is pressed at a high position in the front and pressed at a low position in the rear. In this manner, the battery 12 can be firmly supported by pressing the battery 12 from the front upper side to the rear lower side with the battery holder 123 formed obliquely.

  In the battery holder 123, a CDI installation portion 123f for attaching the CDI unit 121 is provided on the right rear side of the right plate portion 123a. By attaching the CDI unit 121 to the CDI installation portion 123f, the CDI unit 121 is positioned on the right side of the rear portion of the battery 12 as shown in FIG. As described above, since the battery holder 123 has a shape that rises forward, the rear CDI unit 121 is positioned low and contributes to lowering the center of gravity. Above the CDI unit 121 is an empty space, and a starter relay 122 is arranged in this empty space. Thus, since the wiring through which a large current flows can be shortened by bringing the starter relay 122 close to the battery 12, the electric resistance of the wiring can be reduced and the power consumption of the battery 12 can be suppressed. Further, by utilizing the space behind the battery 12 for the arrangement of the CDI unit 121 and the starter relay 122, the CDI unit 121 and the starter relay 122 can be arranged in a compact manner in the vicinity of the battery 12.

  As described above, the CDI unit 121 and the starter relay 122 project rightward from the right side surface of the battery 12 in the vehicle width direction (see FIGS. 4 and 5). For this reason, depending on these arrangements, the CDI unit 121 and the starter relay 122 may interfere with the driver's feet, which may reduce the foot-holding property. Therefore, in the motorcycle 1 of the present embodiment, the CDI unit 121 and the starter relay 122 are arranged on the right rear side of the battery 12 to provide a space for passing a foot forward. Thereby, interference with the driver | operator's foot | leg with the CDI unit 121 and the starter relay 122 can be prevented, and the fall of footing property can be suppressed. Due to the structure of the human body, the protrusion in the vehicle width direction at the upper part of the vehicle body has a greater effect on the footing than the protrusion at the lower part of the vehicle body. In this regard, the configuration in which the electrical component that protrudes outward in the vehicle width direction at the upper part of the vehicle body is disposed at the rear portion of the battery 12 is particularly effective for suppressing a decrease in the footing property.

  An engaging portion 105 having an opening is provided on the upper surface of the air cleaner case 10R. A stay 124 that restricts the vertical movement of the battery 12 is attached to the engaging portion 105. The stay 124 is configured by bending a plate-like member in the same manner as the battery holder 123, and includes a right plate portion 124a extending in the vehicle body vertical direction and an upper plate portion 124b extending leftward from the upper end portion of the right plate portion 124a. With. The stay 124 is fixed to the air cleaner case 10 </ b> R by inserting the upper plate portion 124 b into the opening of the engaging portion 105. The upper plate portion 124b of the stay 124 holds the upper surface of the battery 12 and restricts movement in the vertical direction. The right plate portion 124 a of the stay 124 is fixed to the right plate portion 123 a of the battery holder 123.

  Furthermore, fastening bosses 106a and 106b for fixing the air cleaner 10 to the vehicle body frame 2 are provided on the upper surface of the air cleaner case 10R. Further, a fastening portion 104 a for fixing the air cleaner 10 to the vehicle body frame 2 is provided on the distal end side of the lower support portion 104. The air cleaner 10 is positioned at a predetermined position by fixing the fastening bosses 106a and 106b and the fastening portion 104a to the air cleaner brackets 253 and 254 and the air cleaner bracket 261, respectively.

  A concave portion 107 in which the main tube 21 is positioned is formed on the right front surface of the air cleaner case 10R. The recess 107 is formed from the center to the lower part on the right side of the front surface of the air cleaner case 10R. The concave portion 107 has a shape corresponding to the curved shape of the rear portion 21 b of the main tube 21. Thus, by providing the front surface with the concave portion 107 having a shape corresponding to the main tube 21, the main tube 21 curved downward can be disposed in the concave portion 107.

  As described above, the recess 107 is formed on the right front surface of the air cleaner case 10 </ b> R, and the main tube 21 is disposed in the recess 107. For this reason, the air cleaner 10 is bulged forward so as to avoid the main tube 21 on the left side. Thus, since the capacity of the clean side of the air cleaner 10 can be ensured by having the bulging portion 108 bulging forward on the left side of the front surface of the air cleaner case 10R, the output reduction of the engine 8 due to the occurrence of breathing is suppressed. it can. In addition, the area of the filter element provided inside the air cleaner 10 can be increased.

  A connecting tube 109 connected to the fuel injection device 11 is provided at the center of the bulging portion 108. The connecting tube 109 forms an intake passage that supplies air on the clean side of the air cleaner 10 to the engine 8 side. By providing the connecting tube 109 in the bulging portion 108 that bulges forward, the intake passage can be shortened to increase the throttle response.

  In the motorcycle 1 having such a configuration, the battery 12 is disposed close to the engine 8. FIG. 9 is a right side view showing the structure around the air cleaner 10 and the battery 12. As shown in FIG. 9, a recess 107 is provided on the front surface of the air cleaner 10 so as to overlap the main tube 21 in a side view, and a rear portion 21 b of the main tube 21 is positioned in the recess 107. Thereby, a part of the front left side of the air cleaner 10 is positioned on the left side of the main tube 21 so as to overlap the main tube 21 in a side view. That is, a part of the front left side of the air cleaner case 10 </ b> R and the air cleaner cover 10 </ b> L is positioned on the left side of the main tube 21.

  The front support portion 102 that supports the front surface of the battery 12 is provided above the recess 107 so as to avoid the rear portion 21 b of the main tube 21, and the battery 12 has a front surface that is supported by the front support portion 102. Positioned closer. For this reason, the lower part of the front surface of the battery 12 overlaps the recess 107 and the main tube 21 in a side view. That is, the lower part of the front surface of the battery 12 and the lower part of the front surface of the air cleaner case 10R are arranged so as to sandwich the main tube 21 in the vehicle width direction.

  The battery 12 is disposed relatively forward with respect to the air cleaner 10 because a part of the front surface is positioned on the right side of the main tube 21. Specifically, the center position C2 in the front-rear direction of the battery is positioned in front of the center position C1 in the front-rear direction of the air cleaner 10. As a result, a heavy object is brought close to the engine 8 to suppress the moment of inertia around the center of gravity of the motorcycle 1 and to secure high motion performance.

  As described above, the CDI installation portion 123 f for fixing the CDI unit 121 is provided at the rear portion of the battery holder 123. The CDI installation portion 123f is configured such that the center position C3 in the front-rear direction of the CDI unit 121 to be attached is positioned behind the center position C1 in the front-rear direction of the air cleaner case 10R. Further, the CDI unit 121 is configured such that the front end surface thereof is positioned behind the center position C1 in the front-rear direction of the air cleaner case 10R in a side view. By disposing the CDI unit 121 in this way, a sufficient space for passing a foot can be provided in the front, so that it is possible to suppress a decrease in footing performance.

  In the motorcycle 1 of the present embodiment, the front support portion 102 is provided above the recess 107, and the front side (fixed portion 123d) of the battery holder 123 is fixed to the air cleaner 10 at a position higher than the rear side (fixed portion 123e). Is done. Since the rear portion 21b of the main tube 21 is curved obliquely downward, the front support portion 102 can be provided above the concave portion 107 if the concave portion 107 is formed from the center on the right side of the front surface to the lower portion in the air cleaner 10. That is, the battery holder 123 can be fixed by disposing the front support portion 102 forward so as to avoid the main tube 21, and therefore the battery 12 can be disposed close to the engine 8.

  For example, consider fixing the front side of the battery holder to the air cleaner at a low position. Since the rear portion of the main tube is curved obliquely downward, in this case, a front support portion must be provided behind the main tube. If it does so, a front side support part will prevent arrangement | positioning a battery ahead, and it will become impossible to make a battery adjoin to an engine. On the other hand, the front support portion 102 of the motorcycle 1 of the present embodiment is provided above the recess 107 so as to avoid the main tube 21, and the battery 12 can be disposed forward. . Thereby, the battery 12 can be appropriately brought close to the engine 8 to ensure high exercise performance.

  FIG. 10 is a schematic diagram showing a state in which the battery 12 is firmly supported by the battery holder 123, and shows a state in which the air cleaner 10 and the battery 12 are viewed from the front. As described above, the right plate portion 123a of the battery holder 123 has a front rising shape in which the front side is higher than the rear side. By such a battery holder 123, the battery 12 is pressed leftward (inward in the vehicle width direction) at a high position in the front (arrow f1) and leftward at a low position in the rear (arrow f2). For this reason, even when a lateral force is applied to the battery 12 during traveling, the battery 12 is firmly supported by the battery holder 123 and held in a predetermined position.

  As described above, in the motorcycle 1 of the present embodiment, the battery 12 is supported at different heights in the front and rear directions by the battery holder 123 extending obliquely up and down with respect to the front and rear direction. Even if the battery holding part is not formed so as to surround the battery, the battery can be firmly supported by the battery holder. That is, the battery can be reliably supported without increasing the size of the air cleaner.

  In addition, since a sufficient space for passing a foot can be provided in front of the CDI unit (electrical component) 121 and the starter relay (electrical component) 122, it is possible to suppress a decrease in the footing property. Further, since the CDI unit 121 and the starter relay 122 can be arranged at a low position, the motorcycle 1 can have a low center of gravity. Further, the space behind the battery 12 can be effectively used, and the CDI unit 121 and the starter relay 122 can be compactly assembled in the vicinity of the battery 12.

  Further, since the heavy battery 12 can be positioned near the engine 8 suspended on the main tube 21, the high momentum performance can be ensured by suppressing the moment of inertia around the center of gravity of the motorcycle 1.

  In addition, this invention is not limited to the said embodiment, A various change can be implemented. For example, in the motorcycle of the above embodiment, the starter relay is disposed above the CDI unit, but the position of the starter relay is not limited to this. The starter relay may be disposed below the seat. Further, the arrangement position of the CDI unit is not particularly limited, and the CDI unit may be arranged further rearward. For example, the CDI unit may be arranged at a position overlapping the side tube in the vehicle side view. In this case, it is possible to secure a wider space for passing the feet in front of the CDI unit, so that it is possible to further improve the footing performance.

  Moreover, in the said embodiment, about the magnitude | size, shape, etc. of each structure illustrated by an accompanying drawing, it is not limited to this, It can change suitably within the range which exhibits the effect of this invention. In addition, the present invention can be appropriately modified and implemented without departing from the scope of the object.

  INDUSTRIAL APPLICABILITY The present invention is useful for a backbone type motorcycle having a battery holding part on the side of an air cleaner.
