Accordingly, the bolts 122 are not visually recognized from the outside thus enhancing the external appearance of the motorcycle 1.
On respective side portions of the ridge portion 120, a side recessed portion 123 formed by indenting a side portion of the ridge portion 120 inward in the vehicle width direction is formed at a position between the front lid fixing portion 121a and the intermediate lid fixing portion 121b as well as at a position between the intermediate lid fixing portion 121b and the rear lid fixing portion 121c, respectively.
A plurality of ribs 124 are formed on the upper surface of the upper surface cover 118a in such a manner that the ribs 124 are contiguously with front ends and rear ends of the side recessed portions 123 and extend outwardly in the vehicle width direction toward areas in the vicinity of the stepped portions 118b. 
Due to the formation of each side recessed portion 123 and a pair of ribs 124, 124 which is contiguously formed with the side recessed portion 123, a lower recessed portion 125 which appears to be downwardly indented as viewed in a side view is formed on an upper surface of the upper surface cover portion 118a at four positions. Each lower recessed portion 125 (recessed portion) is arranged so as to be inclined such that the lower recessed portion 125 is directed inward in the vehicle width direction and rearwardly with an outer end of the lower recessed portion 125 in the vehicle width direction set as a proximal end as viewed in a plan view.
FIG. 7 is a plan view of the upper-side box lid 116.
To explain the embodiment with reference to FIG. 2, and FIG. 4 to FIG. 7, the upper-side box lid 116 includes a pair of left and right longitudinally extending portions 130, 130 which extends in the longitudinal direction in a spaced-apart manner in the vehicle width direction; and a center connecting portion 131 (flat portion) which connects the longitudinally extending portions 130, 130 to each other in the vehicle width direction at a center position in the vehicle width direction. The longitudinally extending portions 130, 130 and the center connecting portion 131 are formed into an integral body by resin molding.
The upper-side box lid 116 includes bent portions 132, 132 where the upper-side box lid 116 is bent in the longitudinal direction at an approximately center position thereof in the longitudinal direction. Bent lines of the bent portions 132, 132 extend in the vehicle width direction. The upper-side box lid 116 is formed in an upwardly projecting manner as viewed in a side view by being bent at the bent portions 132, 132 so as to conform with a shape of the upper surface of the lid cover 118.
The longitudinally extending portions 130, 130 are respectively formed into a gutter shape bent in an upwardly projecting manner in cross section as viewed from a rear side in FIG. 5. The longitudinally extending portions 130, 130 respectively include, with each of the left and right bent portions 132, 132 set as a boundary: a front extending portion 133, 133 which extends to the front; and a rear extending portion 134, 134 which extends rearwardly. In the upper-side box lid 116, as viewed in a side view in FIG. 2, the bent portions 132 form apex portions, the front extending portions 133, 133 extend to the front in the frontward and downward direction from the bent portions 132, 132 respectively, and the rear extending portions 134, 134 extend rearwardly in the rearward and downward direction from the bent portions 132, 132 respectively.
The center connecting portion 131 which is formed into an approximately rectangular flat plate shape connects inner edges of the front extending portions 133, 133 to each other in the vehicle width direction. The center connecting portion 131 is arranged approximately horizontally behind the key cylinder 107. Thus, an article, for example, equipment such as a plate-like smart phone P (FIG. 4) can be placed on an upper surface of the center connecting portion 131.
The front extending portions 133, 133 include a pair of left and right arm portions 140, 140 which extends to the front from a front edge 131a of the center connecting portion 131. The arm portions 140, 140 have a tapered shape where a width is gradually decreased toward a front end side.
In the upper-side box lid 116, the longitudinally extending portions 130, 130 are connected to each other by the center connecting portion 131 at center portions thereof in the longitudinal direction, and the arm portions 140, 140 project to the front, and the rear extending portions 134, 134 project rearwardly. Accordingly, the upper-side box lid 116 has an approximately H shape as viewed in a plan view.
Each rear extending portion 134, 134 has upper recessed portions 135 (recessed portions) at positions where the rear extending portions 134, 134 overlap with the lower recessed portions 125 of the lid cover 118 respectively from above as viewed in a plan view. More specifically, the upper recessed portions 135 are formed on four portions corresponding to positions of the respective lower recessed portions 125. When the upper-side box lid 116 is viewed in a side view, the upper recessed portions 135 are formed by cutting out portions of lower edges of the rear extending portions 134, 134 upwardly, and penetrate the rear extending portions 134, 134 in the vehicle width direction respectively. Each upper recessed portion 135 is arranged in an inclined manner such that the upper recessed portion 135 is directed inwardly in the vehicle width direction and rearwardly with an outer end 135a of the upper recessed portion 135 in the vehicle width direction set as a proximal end as viewed in a plan view. More specifically, an inner end 135b of each upper recessed portion 135 in the vehicle width direction is positioned behind the outer end 135a of the upper recessed portion 135.
The upper-side box lid 116 is arranged such that the rear extending portions 134, 134 are positioned on left and right sides of the ridge portion 120 of the lid cover 118 respectively, and the upper-side box lid 116 is fixed by bolts 122 (FIG. 6). The rear extending portions 134, 134 are positioned outside the respective side recessed portions 123 of the lid cover 118 in the vehicle width direction. Accordingly, the respective side recessed portions 123 are exposed upwardly.
When the upper-side box lid 116 is mounted on the lid cover 118, the upper recessed portions 135 and the lower recessed portions 125 are combined with each other so that a plurality of bag mounting holes 136 which penetrate lower portions of the respective rear extending portions 134, 134 in the vehicle width direction are formed. In this embodiment, a pair of bag mounting holes 136 is formed in each rear extending portion 134 in the longitudinal direction of the vehicle. More specifically, the bag mounting hole 136 are formed in four portions in total. The bag mounting hole 136 is formed in an inclined manner such that the bag mounting hole 136 is directed inwardly in the vehicle width direction and rearwardly with an outer end thereof in the vehicle width direction set as a proximal end.
Further, when the upper-side box lid 116 is mounted on the lid cover 118, the front extending portion 119 (FIG. 6) of the lid base 117 is covered by a front portion of the upper-side box lid 116 from above.
As shown in FIG. 4, in a state where the box lid 52 is closed, the front edge 131a of the center connecting portion 131 of the upper-side box lid 116 is contiguously formed with an upper rear edge of the front top cover 110, and the arm portions 140, 140 are positioned on left and right sides of the key cylinder 107 respectively.
To be more specific, the arm portions 140, 140 are arranged at positions substantially equal to the position of the key cylinder 107 in the longitudinal direction of the vehicle, and are positioned outside the key cylinder 107 respectively in the vehicle width direction. More specifically, the arm portions 140, 140 are arranged so as to surround the key cylinder 107 from left and right sides.
In a state where the box lid 52 is closed, the arm portions 140, 140 cover an upper portion of the front top side cover 111 (FIG. 6).
An operator seated on the front seat 41 can easily and quickly open the box lid 52 in such a manner that the rider unlocks the box-side locking mechanism 102 by manually operating the key cylinder 107. Thereafter, the operator directly moves his/her hand sideward so as to grip at least either one of the arm portions 140, 140, and rotates the box lid 52 rearwardly while gripping the arm portion 140. The key cylinder 107 is arranged at the position where the rider can easily extend his hand to the key cylinder 107, and the side of the key cylinder 107 is also arranged at the position where the rider can easily extend his hand to the side in the same manner as the key cylinder 107. Thus, the rider can easily grip the arm portions 140, 140 and can perform opening and closing of the box lid 52.
Further, when the box-side locking mechanism 102 is unlocked, the box lid 52 slightly moves in the opening direction due to a biasing force of a spring (not shown in the drawing) mounted on the box lid 52, the box-side locking mechanism 102 or the like. Accordingly, a rider can easily grip the arm portions 140, 140.
As shown in FIG. 5, a bag 145 which can store an article therein may be mounted on the box lid 52. The bag 145 includes a box-shaped bag body 146 and a connecting member 147 which connects the bag body 146 to the box lid 52. In this embodiment, the connecting member 147 is formed of a left-and-right pair of strings disposed on a front portion of a lower portion of the bag body 146; and a left-and-right pair of strings disposed on a rear portion of the lower portion of the bag body 146. These strings are connected to each other by buckles, for example. However, a connection state of the connecting members 147 is not particularly limited.
The bag 145 is arranged on a rear portion of the upper-side box lid 116, and is connected to the rear extending portions 134, 134. To be more specific, the respective connecting members 147 are made to pass through the respective bag mounting holes 136 in the vehicle width direction, and are connected to the rear extending portions 134, 134 in a binding manner.
In this embodiment, the respective connecting members 147 are connected to the pair of left and right rear extending portions 134, 134 which are away from each other in the vehicle width direction. More specifically, it is possible to increase a distance between the positions where the bag 145 is connected so that the bag 145 can be firmly connected to the box lid 52.
Further, a space is formed between the left and right rear extending portions 134, 134. Thus, it is possible to make the upper-side box lid 116 lightweight. Even when the upper-side box lid 116 is made lightweight, the bag 145 can be firmly connected.
The rear extending portions 134, 134 extend rearwardly and downwardly. Thus, the bag 145 that has a large height can be mounted on the box lid 52 without becoming an obstacle to a rider. Thus, the capacity of the bag 145 can be increased. Since the bag 145 minimally becomes an obstacle, even in a state where the bag 145 is mounted on the box lid 52, the rider can grip the arm portions 140, 140 and can easily perform an opening and closing of the box lid 52.
A portion of a flow of air W (FIG. 6) from a front side which flows along the periphery of the box lid 52 enters the inside of the bag mounting holes 136 from outer ends of the respective bag mounting holes 136 in the vehicle width direction, and is discharged toward an upper side of the ridge portion 120 from inner ends of the respective bag mounting holes 136 in the vehicle width direction. More specifically, the respective bag mounting holes 136 are formed so as to allow a flow of air (wind) to flow toward the inside in the vehicle width direction from the outside in the vehicle width direction and rearwardly. Accordingly, even in the configuration where a height of the box lid 52 becomes high due to the provision of the upper-side box lid 116, the flow of air W can be made to efficiently flow rearwardly. Thus, the motorcycle 1 can ensure operational performance.
As has been explained heretofore, according to the embodiment to which the invention is applied, the motorcycle 1 includes the head pipe 14; the main frames 15, 15 which extends rearwardly from the head pipe 14; the storage box 51 which is arranged in the vicinity of the main frames 15, 15 in a state where the storage box 51 opens upwardly; and the box lid 52 which covers the opening portion 51a of the upwardly openable storage box 51 in an openable and closable manner, wherein the key cylinder 107 which operates the box-side locking mechanism 102 for locking the box lid 52 is arranged behind the handle holder 25 and in front of the storage box 51, and the box lid 52 includes the arm portions 140, 140 positioned on sides of the key cylinder 107. Due to such a configuration, a rider can operate the key cylinder 107 which is positioned behind the handle holder 25 and in front of the storage box 51 thus not being positioned excessively close to the occupant. Thus, the occupant can easily operate the key cylinder 107 and, at the same time, can easily perform an opening or closing operation of the box lid 52 by gripping the arm portions 140, 140 of the box lid 52 being arranged on sides of the key cylinder 107 and not being positioned excessively close to the rider. Accordingly, operability of the key cylinder 107 and operability of opening or closing of the box lid 52 can be enhanced with the simple structure.
The box lid 52 includes the lower-side box lid 115 and the upper-side box lid 116 for covering the lower-side box lid 115 from above, wherein the arm portions 140, 140 are formed on the upper-side box lid 116. Accordingly, the degree of freedom in setting the shape of the upper-side box lid 116 can be increased. Thus, the arm portions 140, 140 can be easily formed.
The upper recessed portions 135 and the lower recessed portions 125 are formed in the upper-side box lid 116 and the lower-side box lid 115 respectively thus forming the bag mounting holes 136. Accordingly, the bag 145 can be easily mounted on the box lid 52 without providing a dedicated part or the like for mounting the bag 145.
The bag mounting holes 136 are formed so as to allow a flow of air to flow toward the inside in the vehicle width direction from the outside in the vehicle width direction and rearwardly. Thus, even in the configuration where a height of the box lid 52 becomes high due to the provision of the upper-side box lid 116, it is possible to make the flow of air W efficiently flow rearwardly whereby the motorcycle 1 can ensure an operational performance.
The upper-side box lid 116 is formed into an approximately H-shape as viewed in a plan view by including a pair of left and right rear extending portions 134,134 which extends rearwardly, and the bag mounting hole 136 is formed on a side of the upper-side box lid 116 where the pair of left and right rear extending portions 134,134 is provided. With such a configuration, the bag 145 can be supported by the pair of left and right rear extending portions 134,134 provided to a rear portion of the upper-side box lid 116 having an approximately H shape at positions close to the outside in a vehicle width direction. Thus, the bag 145 can be supported firmly and, at the same time, the upper-side box lid 116 can be made lightweight.
The bent portions 132,132 where the upper-side box lid 116 is bent in a longitudinal direction of the vehicle 1 is formed on the upper-side box lid 116, the bag mounting holes 136 are formed in the upper-side box lid 116 behind the bent portions 132, 132, and the arm portions 140, 140 are formed on the upper-side box lid 116 in front of the bent portions 132, 132. Accordingly, the external appearance of the upper-side box lid 116 at the time of not mounting the bag 145 can be enhanced by the bent portions 132, 132, and the bag 145 can ensure a large capacity when the bag 145 is mounted. Further, a distance can be ensured between the bag 145 and the arm portions 140, 140. Thus, the bag 145 minimally becomes an obstacle whereby the operability of the arm portions 140, 140 can be enhanced.
Further, the bent portions 132, 132 where the upper-side box lid 116 is bent in a longitudinal direction of the vehicle 1 is formed on the upper-side box lid 116, and the upper-side box lid 116 has the center connecting portion 131 which is formed approximately flat at the center in a vehicle width direction at a position in front of the bent portions 132, 132 and behind the key cylinder 107. Accordingly, the smartphone P or the like can be arranged on the center connecting portion 131 formed approximately flat at the center in the vehicle width direction.
The above-mentioned embodiment merely shows one mode to which the invention is applied, and the invention is not limited to the above-mentioned embodiment.
An explanation has been made with respect to the case where the bag mounting holes 136 are formed by forming the upper recessed portions 135 and the lower recessed portions 125 on the upper-side box lid 116 and the lower-side box lid 115 respectively. However, the invention is not limited to such a configuration. The bag mounting holes may be formed by forming recessed portions on at least one of the upper-side box lid 116 and the lower-side box lid 115.
An explanation has been made with respect to the case where the pair of arm portions 140, 140 is arranged so as to surround the key cylinder 107 from left and right sides. However, the invention is not limited to such a configuration, and the arm portion 140 may be formed only either on a left side or on a right side.
In the above embodiment, the storage part 50 is disposed above the rear portions of the main frames 15, 15. However, the invention is not limited to such a configuration, and the storage part 50 may be disposed between the left and right main frames 15, 15 or above a main frame when the main frame is formed of a single frame.
A motorcycle is used as an example of a saddle-ride-type vehicle. However, the saddle-ride-type vehicle may be a vehicle having three or more wheels, for example.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
