Further, the second rear frames 8 and 8 are configured by pipe frames extending rearward and upward at a gentle angle closer to the horizontal than the first rear frames 7 and 7, and rear portions thereof are rearwardly raised from the first rear frames 7 and 7. And a pipe-like cross frame 8A is provided in a portion on the front side of the vehicle with respect to the connecting portion.
That is, the cross frame 8A of the second rear frames 8, 8 and the cross frame 7C of the first rear frames 7, 7 (intermediate cross frame 7C1, rear cross frame 7C2) are connected between the front portions of the rear frames 6, 6. A cross frame for connecting the middle part and the rear part is formed, and the cross frame layout is advantageous for securing the rigidity of the rear frames 6 and 6 as a whole. Further, the front end portion of the rear fender 18E is hooked on the cross frame 8A, and reference numeral 5A in FIG. 5 indicates a pipe-like cross frame disposed between the pivot brackets 5 and 5.

In this configuration, a pair of left and right storage box support stays 8B and 8B that support the rear portion of the storage box 51 are provided near the cross frame 8A of the second rear frames 8 and 8 of the rear frames 6 and 6, and the main frame 4 A single storage box support stay 4F for supporting the front portion of the storage box 51 is provided in the vicinity of the rear frames 6 and 6 (see, for example, FIG. 4). The storage box 51 has bolts 42 (see FIGS. 2 and 6) on the stays 8B, 8B, and 4F via vibration-proof mounting rubber 40 (see FIG. 6 described later) and washers 41 (see FIGS. 2 and 6). ) And a nut 43 (see FIG. 6). As a result, as shown in FIGS. 2 and 3, the storage box 51 is supported by the vehicle body frame 3 at a substantially intermediate position in the vehicle front-rear direction. , 6 are arranged.
Further, on the left and right (outside the vehicle) in the vicinity of the cross frame 8A, a support stay 8C that supports a regulator that constitutes a part of the engine drive system, and an electronic control unit (ECU) that controls each part of the motorcycle 1 are supported. The ECU support stay 8D is integrally provided, that is, the vehicle component parts are collectively supported at a portion where the frame strength is relatively high.

  Further, a pair of left and right fuel tank support stays for supporting the fuel tank 50 are provided in the rear portions of the second rear frames 8, 8, that is, in the vicinity of the connecting portion between the second rear frames 8, 8 and the first rear frames 7, 7. 8E and 8E are integrally formed, and thereby the fuel tank 50 is also supported at a portion where the frame strength is relatively high. 2 and 3, reference numeral 50 </ b> P is a fuel pump disposed in the front space of the fuel tank 50.

By the way, when the storage box 51 is arranged as described above, generally, the storage box 51 is swelled between the left and right rear frames 6 and 6 to ensure a large storage volume. The helmet which is a large storage component desired to be stored in 51 can be stored.
On the other hand, this type of motorcycle 1 includes a battery 55 that supplies electric power to various electrical components (electronic control device, regulator, etc.) provided in the vehicle. In this configuration, as shown in FIGS. In addition, the battery 55 is disposed in the storage box 51. Generally, when the battery 55 is disposed in the storage box 51, the waterproof structure of the storage box 51 itself can be used as compared with the case where the battery 55 is disposed in a place other than the storage box 51. On the other hand, there is an advantage that the waterproof structure of the battery storage part 71 to be omitted can be omitted or simplified, and the storage capacity is reduced by the amount of the battery 55.
In order to secure a sufficient storage capacity while arranging the battery 55, a method of simply expanding the battery 55 between the rear frames 6 and 6 to secure the storage capacity of the storage box 51 can be considered. In the portion where the battery 55 is present, the cross frame connecting the left and right rear frames 6, 6 is not provided, and the layout of the cross frame is restricted.
Therefore, in this configuration, the storage capacity capable of storing the helmet is ensured while improving the flexibility of layout of the cross frame. Hereinafter, the storage box will be described together with the battery arrangement structure.

6 is a side view of the storage box 51, FIG. 7 is a top view, and FIG. 8 is a rear view. In addition, in each figure, the code | symbol 60 is the several (three) bolt insertion hole at the time of carrying out the bolt fastening of the storage box 51 to the main frame 4 (stays 8B, 8B, 4F).
The storage box 51 has a box shape that opens upward, and a support arm portion 61 that protrudes forward is integrally projected at the front upper center of the front wall 51 </ b> A of the storage box 51. The front end of the occupant seat 52 is rotatably connected via a shaft inserted through the shaft insertion hole 62. Thus, the occupant seat 52 rotates so as to freely open and close the upper opening of the storage box 51, and the occupant seat 52 is configured to be locked in a closed state by a lock mechanism (not shown).
The front wall 51A of the storage box 51 is supported by the body frame 2 and extends to the vicinity of the main frame 4 of the body frame 2, as shown in FIG. As shown in FIG. 6, a front bottom wall 51B1 extending downward and downward along the inclination of the main frame 4 from the lower edge of the front wall 51A, and a vertical wall 51B2 extending vertically upward from the rear end of the front bottom wall 51B1. And a rear bottom wall 51B3 extending rearward and upward substantially along the inclination of the second rear frame 8, 8 from a position near the upper side of the second rear frame 8, 8.

That is, the front portion of the storage box 51 (the storage portion corresponding to the front bottom wall 51B1) extends downward between the second rear frames 8 and 8 and is located in the vicinity of the main frame 4 so as to be the deepest portion of the storage box 51. As shown in FIG. 1, this portion is formed when the half-type helmet 100 is inserted into the storage box 51 with the visor 101 side down. It is formed to have a longitudinal length, depth and width that can accommodate the front side (the portion on the visor 101 side).
Further, a rib (storage component positioning rib) 64 is provided on the bottom (front bottom wall 51B1) of the bulging portion 63 so as to protrude upward with a space in front of the vertical wall 51B2. Drain holes 65 and 66 are provided in the front and rear, and the rib 64 is integrally provided in advance at a position where the visor 101 of the helmet 100 abuts and the storage position of the helmet 100 can be positioned.

A battery storage portion 71 for storing the battery 55 is provided at a rear portion of the storage box 51, and a battery cover 81 that covers the battery 55 stored in the battery storage portion 71 from above is detachably provided. First, the battery storage part 71 will be described in detail.
As shown in FIG. 6, the central portion of the rear bottom wall 51 </ b> B <b> 3 of the storage box 51 includes a first inclined surface 72 extending rearward and downward from the upper end of the vertical wall 51 </ b> B <b> 2 in a side view, and the rear of the first inclined surface 72. A V-shaped bottom cross-sectional shape is formed by the second inclined surface 73 extending rearward and upward from the lower portion, and as shown in the figure, a battery storage recess (battery front portion) for storing the front portion of the battery 55 is formed. A storage part) 75 is formed. A hole 75A used for wiring or draining is formed in the deepest portion of the battery housing recess 75.

The rear wall 51C of the storage box 51 is formed with a battery storage protrusion (battery rear storage) 76 that protrudes rearward of the vehicle and stores the rear portion of the battery 55. The battery storage protrusion 76 forms a third inclined surface 77 that is continuous with the second inclined surface 73 of the battery storage recess 75, and from the rear end of the third inclined surface 77 to the third inclined surface 77. Thus, a fourth inclined surface 78, which is an upwardly inclined surface in the vertical direction (substantially parallel to the first inclined surface 72), is formed.
Here, the battery storage protrusion 76 is configured as a separate component from the storage box 51. That is, as shown in FIG. 8, an opening 67 is provided in the rear wall 51 </ b> C of the storage box 51, and a battery storage protrusion 76 is applied so as to close the opening 67. The battery accommodating protrusions 76 are connected by screws or the like using a plurality of holes 68 formed around the periphery of the battery. FIG. 7 also shows a state in which the battery accommodating protrusion 76 is removed as in FIG.

The battery 55 stored in the battery storage unit 71 has a rectangular parallelepiped shape like a general battery, and the battery storage unit 71 has a longitudinal direction of a horizontal cross section when the battery 55 is horizontally disposed in the vehicle. The battery 55 is accommodated in a layout (vertical layout) that matches the front-rear direction. That is, as shown in FIGS. 6 and 7, when the longitudinal dimension of the horizontal section of the battery 55 is represented by the value BL and the short dimension is represented by the value BH, the separation distance in the vehicle front-rear direction of the battery housing portion 71 is the value BL. The separation distance in the vehicle width direction is slightly larger than the value BH (see FIG. 7).
Thus, since the battery 55 is vertically arranged in the center in the vehicle width direction, a relatively large storage space can be secured on the left and right of the battery 55 in the storage box 51, and the relatively heavy battery 55 is placed in the center in the vehicle width direction. Therefore, the center of gravity of the vehicle can be easily set at the center in the vehicle width direction. Further, by placing the battery 55 vertically, a support portion (bolt insertion hole 60 or the like) can be disposed on the side of the battery 55, and without increasing the width of the storage box 51, in the vicinity of the heavy battery 55. A support can be arranged.

For this reason, as shown in FIG. 1, the part which protrudes in the storage box 51 of the battery 55 is accommodated in the inner space (space where a head enters) of the helmet 100, and the parts on both sides of the helmet 100 are left and right of the battery 55. In other words, the helmet 100 can be efficiently stored in the storage box 51.
Note that the opening edge 51X of the storage box 51 is inclined forward and downward as viewed from the side of the vehicle, thereby exposing a part of the helmet 100 in the storage box 51 to the outside of the opening edge 51X. Is covered with an occupant seat 52 (see FIG. 1). According to this, when the passenger seat 52 is opened, a part of the helmet 100 is exposed, and the helmet 100 can be easily taken out and stored by holding the exposed part by hand. Further, when the battery 55 is attached to or detached from the storage box 51, if the battery 55 is attached or detached from the front side of the storage box 51, the vertical movement amount of the storage box 51 can be reduced, and the battery 55 can be easily attached or detached. Can do.

Further, as shown in FIG. 6, in the vehicle side view, the inclination angle θ of the battery 55 is set to an angle of 90 degrees or more (that is, an obtuse angle) with respect to the rear wall 51C (vertical wall) of the storage box 51, As a result, the rear lower portion of the battery 55 protrudes outside the storage box 51. In the case of this layout, as shown in FIG. 3, a substantially triangular space surrounded by the rear wall 51 </ b> C of the storage box 51, the front part 50 </ b> A inclined obliquely downward and rearward of the fuel tank 50, and the rear frames 6 and 6. Can be efficiently used as a layout space for the battery 55, and when the battery 55 is taken out from the storage box 51, the battery 55 is removed in a direction away from the rear wall 51C. .
In addition, as shown in FIG. 6, an outer shape projection surface 55X obtained by projecting the outer shape of the battery 55 in a direction orthogonal to the upper surface or the bottom surface of the battery 55 passes through the opening edge 51X of the storage box 51. When attaching / detaching, the opening edge 51X does not get in the way, and the attaching / detaching work of the battery 55 can be made easier.

Next, the battery cover 81 will be described. FIG. 9 is a perspective view of the battery cover 81. The battery cover 81 is a cover that covers the protruding portion of the battery 55 that is stored in the battery storage portion 71 and protrudes into the storage box 51, and includes a first cover portion 81A that is connected to the rear wall 51C of the storage box 51; The second cover portion 81B has a shape that bulges from the first cover portion 81A and substantially follows the outer shape of the protruding portion of the battery 55.
At the upper part of the first cover portion 81A, an engaging claw 82 engaged with an opening (engagement hole) 69A (see FIG. 6) formed in the rear wall 51C of the storage box 51, and the first cover portion 81A. Is integrally formed with a screwing portion 83 for screwing it into a screw hole 69B (see FIG. 6) formed in the rear wall 51C of the storage box 51, and the engaging claw 82 of the second cover portion 81B. A pair of left and right engagement claws inserted into a pair of left and right openings (engagement holes) 69C and 69C (see FIG. 7) formed in the rear bottom wall 51B3 of the storage box 51 are located at the front lowermost portion farthest from the front. 84 and 84 are integrally formed.

Therefore, when mounting the battery cover 81, the pair of left and right engaging claws 84, 84 of the battery cover 81 are inserted into the pair of left and right openings 69C, 69C formed in the rear bottom wall 51B3 of the storage box 51. If the battery cover 81 is rotated toward the rear wall 51C side of the storage box 51 with reference to this insertion portion, the engagement claw 82 of the battery cover 81 is an opening formed in the rear wall 51C of the storage box 51. The battery cover 81 can be easily temporarily fixed to the storage box 51 by engaging with 69A. If the screwing portion 83 of the battery cover 81 is screwed into the screw hole 69B of the storage box 51, the battery cover 81 is securely fixed to the storage box 51, so that the battery cover 81 can be easily attached and detached. Can do.
Thus, since the battery 55 is covered with the battery cover 81 from above, exposure of the electrode part and wiring exposed on the upper surface of the battery 55 can be avoided.
In addition, since the concave portions 86 and 87 formed on the upper surface and the front surface of the second cover portion 81B of the battery cover 81 respectively contact the upper surface and the front surface of the battery 55 and press the battery 55 toward the battery storage portion 71, Thereby, the battery 55 can be reliably supported by the battery storage part 71, and the position shift of the battery 55 can be prevented.

In this embodiment, as shown in FIGS. 1 and 3, the battery 55 and the battery storage portion 71 that stores the battery 55 are located above the rear frame 6 (when the rear frame 6 is used as a reference) in a vehicle side view. The battery 55 and the battery storage part 71 are removed from between the rear frames 6 and 6 even when at least a part of the battery 55 is protruded and stored in the storage box 51. When the cross frame 8A for connecting the rear frames 6 and 6 is provided, the layout flexibility of the cross frame 8A can be improved. For example, the position of the cross frame 8A shown in FIG. 3 can be changed in the front-rear direction. Moreover, it can also be arrange | positioned under the battery 55 like an Example. Thereby, the freedom degree of adjustment of the rigidity balance of the vehicle body frame 2 can also be raised.
Moreover, since the battery 55 and the battery storage portion 71 are arranged at positions different from the bulging portion 63 that bulges between the pair of left and right rear frames 6 and 6 of the storage box 51, the bulging portion 63 can be made small and the rear A space without the battery 55, the battery storage portion 71, and the storage box 51 can be reliably secured between the frames 6 and 6, and the layout space of the cross frame 8A connecting the rear frames 6 and 6 can be reliably secured.

Since it is configured to be stored, it is possible to secure a relatively large storage space on the left and right sides of the battery 55 in the storage box 51, and to prevent the storage box 51 from being enlarged in the vehicle width direction while allowing the helmet 100 to be stored. Can do.

Further, the battery 55 is disposed in an inclined manner in the storage box 51 in a side view of the vehicle, and an external projection surface 55X obtained by projecting the external shape of the battery 55 in a direction orthogonal to the upper surface or the bottom surface of the battery 55 is stored. Since it passes through the opening edge 51X of the box 51, the opening edge 51X does not get in the way when the battery 55 is attached / detached, and the attachment / detachment work of the battery 55 can be facilitated.
Further, a cross frame 8A is provided between the front portions of the pair of left and right rear frames 6, 6, and the rear frames 6, 6 support the storage box 51 in the vicinity of the cross frame 8A. It can be arranged near the front of the vehicle, and accordingly, a layout space for vehicle components can be secured between the rear frames 6 and 6, or an empty space between the rear frames 6 and 6 can be widened.
In this configuration, as shown in FIG. 3, by providing the cross frame 8A in the front part of the rear frames 6 and 6, the space vacated behind the cross frame 8A is used as the layout space for the rear fender 18E. The rear fender 18E can be disposed close to the front of the vehicle, and accordingly, the rear wheel 15 can be disposed closer to the front than before, that is, the distance between the front wheel shaft and the rear wheel shaft (wheel base) can be shortened, For example, the longitudinal length of the vehicle can be shortened. Further, since the rear frames 6 and 6 support the storage box 51 in the vicinity of the cross frame 8A, the storage box 51 can be firmly supported.

As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this, A various design deformation | transformation can be performed. For example, in the above-described embodiment, the pair of left and right rear frames 6, 6 includes a first rear frame (seat rail) 7, 7 and a second rear frame (above the front part of the first rear frame 7, 7). The sub-frames 8 and 8 have been described. However, the present invention is not limited to this, and the frames 7 and 8 and the layout may be changed as appropriate. There may be one frame. Further, the present invention may be applied not only to the single body frame 2 as the main frame 4 but also to a body frame including a pair of left and right main frames. Moreover, although the case where the storage box 51 is disposed on the main frame 4 and the pair of left and right rear frames 6 and 6 has been described in the above embodiment, the present invention is not limited to this, and the storage box 51 may be mounted on the main frame 4 depending on the frame configuration. The present invention can also be applied to a case where it is arranged on the rear frames 6 and 6 without being arranged on the top.
