As shown in FIG. 6, the knob 43h is in contact with or very close to the inner wall 44a of the frame cover 44 when the frame cover 44 is attached to the vehicle body frame 2. Projected.
[0027]
As shown in FIG. 7, an electric component holder 43j formed separately is attached to the left side wall portion of the battery holder 43a by a rivet.
In addition, a locking portion 43k is formed at the lower center of the battery holder 43a so as to protrude outward, and is positioned and held by a mounting bracket 30 welded to the vehicle body frame 2.
[0028]
The accessory storage chamber 43 is attached to the vehicle body by being fastened to the vehicle body frame by two attachment bolts (not shown) using two attachment holes 43c formed in the upper part of the battery holder 43a. Positioning and fixing are performed by the portion 43k.
[0029]
Next, storage of articles in the accessory storage chamber 43 of this embodiment will be described.
First, as shown in FIG. 5, the battery 42 is stored in a state of being horizontally placed in the battery holder 43 a above the accessory storage chamber 43 from above the accessory storage chamber 43 with the seat 16 removed. Place it in the height direction lower. The upper part of the battery 42 is pressed by the battery cover 43d and held in the battery holder 43a.
[0030]
Storage of tools, accessories, etc. is performed with the side stand 29 upright and the vehicle body tilted to the left side of the vehicle. At this time, the vehicle right side of the vehicle body faces obliquely upward. In this state, the frame cover 44 is removed, and the storage portion 43b of the accessory storage chamber 43 is exposed.
[0031]
Next, the inner lid 43g attached to the storage portion 43b is removed, and the opening 43f is opened to store tools and small items. When the storage operation is completed, the inner lid 43g is attached to the opening 43f, and the frame cover 44 is attached from the outer side to complete the storage operation.
[0032]
Since it comprised as mentioned above, according to this embodiment, the structure of the accessory storage chamber 43 has the battery holder 43a and the accommodating part 43b, the said battery holder 43a is made into a box shape, and the bottom of the said battery holder 43a. Since the storage portion 43b is tapered toward the lower side, the accessory storage chamber 43 can be stored in an inverted triangular space at the rear of the vehicle body central space, saving space without being exposed to the outside. Storage of goods is possible.
[0033]
In addition, according to the present embodiment, the inner lid 43g is configured separately from the storage portion 43b, so that the accessory storage chamber 43 can be formed without making it complicated.
Further, according to the present embodiment, the knob 43 h is formed on the inner lid 43 g, the knob 43 h is covered with the frame cover 44, and the knob 43 h is pressed by the inner wall 44 a of the frame cover 44. In addition to preventing rattling of the inner lid 43g, it is possible to prevent the inner lid 43g from coming off unexpectedly, and to prevent the articles in the storage portion 43b from falling off.
[0034]
Further, according to the present embodiment, the locking portion 43k is formed on the lower side of the storage portion 43b, and the locking portion 43k is fitted and fixed to the bracket 30 welded to the vehicle body frame 2, and the battery holder 43a. Since the battery holder 43a, the storage portion 43b, the battery cover 43d and the electric component holder 43j can be unitized and attached as a unit, the attachment of the accessory storage chamber 43 is simplified. Workability can be improved.
Further, by providing the side stand 29 so that the vehicle body tilts to the left in the vehicle body width direction, the vehicle body width direction right side of the vehicle body is inclined upward, and an opening 43f is formed on the side surface of the accessory storage chamber 43 on the right side in the vehicle body width direction. Thus, the storing operation can be performed easily and reliably, and the frame cover 44 for covering the opening 43f is detachably disposed on the vehicle body frame 2, so that the articles are dropped from the opening 43f. The crime prevention effect can be enhanced by covering the accessory storage chamber 43 from the outside.
[0035]
In the present embodiment, the inner lid 43g is configured separately from the storage portion 43b. However, the present invention is not limited to this, and for example, the storage portion and the inner lid are partially connected. It may be configured as described above. According to this configuration, there is an advantage that when the inner lid is removed when the article is stored, the inner lid is not forgotten to be closed or lost.
[0036]
The vehicle body structure of the motorcycle according to the present invention is not limited to the above-described illustrated examples, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
[0037]
【The invention's effect】

[0038]
Specifically, according to the present invention, a rear cushion unit, an air cleaner constituting the intake device of the engine, and one end side connected to the exhaust port of the engine are provided in the vehicle body central space surrounded by the engine, the seat, and the rear fender. An exhaust pipe connected to an exhaust silencer disposed at the rear of the vehicle body with the other end extending rearward, and a power source battery having a rectangular parallelepiped shape. The air cleaner extends in the up-down direction in a state of being inclined forward, and the air cleaner is disposed in a substantially L shape in plan view in a space in front of the rear cushion unit and one side in the vehicle body width direction. A vehicle body structure of a motorcycle in which a pipe extends and is arranged in the front-rear direction at a lower portion on the other side in the vehicle body width direction opposite to the air cleaner, and above the exhaust pipe, and By arranging the long side of the rectangular parallelepiped in a substantially horizontal direction in a space formed between the other side in the vehicle width direction of the rear cushion unit and the rear fender below the seating seat, It can be stored in a small space in the vertical direction, and by placing a small article storage room in the space below the battery obtained by space saving, it can be stored inside the car body without adding a luggage box etc. outside the car body. Items such as tools and manuals can be stored.
[0040]
Further, according to the present invention, the accessory storage chamber includes an inner lid that closes the opening to prevent the article from falling off, and the inner lid has a knob that protrudes outward in the lateral direction of the vehicle body. By providing, the opening / closing operation | work of an inner lid can be made easy and the efficiency of workability | operativity can be aimed at. In addition, by forming the knob portion so as to contact the inner side surface of the frame cover when the frame cover is mounted, the knob portion can be pressed, and the ratchet of the inner lid is prevented and the knob is removed unexpectedly. It is possible to prevent this, and to prevent the articles in the storage unit from falling off.
There are excellent effects as described above.
