2. Description of the Related Art Japanese Unexamined Patent Publication No. Hei 5-254472 discloses a front cover body having a maintenance opening on the front surface,
A front cover composed of a maintenance lid that covers the maintenance opening is shown. The maintenance opening is formed in a window hole shape at the center of the front surface of the front cover body, and the maintenance lid is formed by engaging a locking piece formed at an upper edge thereof with a locking piece formed above the maintenance opening. It is inserted into the hole, and the lower left and right are overlapped with the step formed on the lower right and left inside of the maintenance opening, and attached by screws.

[0003]

As described above, when the periphery of the maintenance lid is fixed so as to be attached to the front cover body, the maintenance opening must be formed in a window hole shape. The opening area of the portion becomes small. It is also desired that the number of mounting locations be as small as possible to improve the maintainability. An object of the present invention is to solve such a problem.

[0004]

According to a first aspect of the present invention, there is provided a scooter-type vehicle having a front cover provided in front of a leg shield and a front opening provided with a maintenance opening. In a scooter-type vehicle that consists of a cover body and a maintenance lid that covers this maintenance opening, the upper and lower parts of the front cover body maintenance part are attached to the leg shield, the lower front part is attached to the body frame, and the upper part of the maintenance lid The left and right sides are attached to the leg shield, and the lower side than this attachment portion is attached to the vehicle body frame.

A second invention is characterized in that, in the first invention, a lower end portion of the maintenance lid is positioned higher than a vehicle-body-side mounting portion of the front cover body.

[0006]

According to the first aspect of the present invention, the upper part of the maintenance lid is mounted on the leg shield, and the lower side of the mounting position is mounted on the vehicle body frame, so that it is not necessary to mount the lid on the front cover body. Therefore, the opening area of the maintenance opening can be made larger than in the conventional example in which the periphery of the maintenance lid is attached to the front cover body.

[0007] When the maintenance lid is mounted, the minimum number of mounting points is three, that is, the upper left and right and one lower part.
Since the number of mounting locations can be reduced, the number of mounting locations can be reduced as much as possible, thereby improving maintainability.

According to the second aspect of the present invention, since the lower end of the maintenance lid is located above the vehicle-body-side mounting portion of the front cover main body, no mounting hole for mounting the front cover main body is formed in the maintenance lid. I'm done. Therefore, when the car is not attached to the front cover, the appearance is improved.

A front portion of the vehicle body is covered with a front cover 20 and a leg shield 21 from the front and rear of the head pipe 4, and
The front cover 20 is separated into a front cover body 22 and a maintenance lid 23.

The front cover body 22 includes the head pipe 4
The front lower portion is attached to a lower stay 24 extending forward from the front, and the maintenance lid 23 is also attached to an upper stay 25 extending forward from the head pipe 4 at the center.

Since the lower stay 24 and the upper stay 25 are integral with the head pipe 4 constituting a part of the body frame, the front cover body 22 and the maintenance lid 23 are respectively attached to the body frame. The head pipe 4, the center frame 7, and the rear frame 8 constitute a body frame.

The front cover body 22 and the lower stay 24
Mounting part and maintenance lid 23 and upper stay 2
5 has a long bolt 2 as shown by a virtual line.
By providing 6, the car 27 can be supported.

Further, a lower stay 2 is provided by utilizing an article storage portion 29 (FIG. 3) which is a space inside the front cover 20.
A battery 28 is supported on the head pipe 4 between the upper stay 4 and the upper stay 25. The symbol F indicates the bottom bridge 3
It is a movable fender integrated with the fender.

Next, the front cover 20 will be described. As is apparent from FIG. 1, the front portion of the front cover main body 22 is cut out at the uppermost portion to form a maintenance opening 30. The maintenance opening 30 allows the head pipe 4 in the article storage unit 29 to be opened. The maintenance of the battery 28 supported by the battery is enabled.

The left and right side edges of the maintenance opening 30 form a stepped portion 31 which is lowered rearward by the thickness of the maintenance lid 23, and an engagement slit 32 is formed vertically separated therefrom.

A cross portion 33 is provided between the upper portions of the left and right step portions 31.
At the same time, a mounting portion 34 is formed on the upper extension of each step portion 31, and is screwed to a boss 35 projecting forward from the left and right upper end portions of the leg shield 21.

The lower edge of the maintenance opening 30 is
A stepped portion 36 is formed which falls to the rear side of the vehicle body, and mounting holes 37 are formed on the left and right sides thereof.
To the lower stay 24.

A diagonally downward opening 39 is also formed below the stepped portion 36, and the horn of the horn 40 disposed inside the front cover 20 and supported by the lower stay 24 through this opening 39 is directed to the outside. It is audible.

The maintenance lid 23 is a member that opens and closes the maintenance opening 30. When the maintenance lid 23 covers the maintenance opening 30, the left and right ends overlap the left and right steps 31 and are integrally formed. The locking projection 41 is engaged with the corresponding engagement slit 32.

A mounting hole 42 formed at the center is provided with a nut 43 provided at the front end of the upper stay 25 (FIG. 3).
And is attached by the screw 44 here.

Further, bosses 45 projecting rearward are formed on the left and right rear surfaces of the upper end of the maintenance lid 23, and are formed so as to project forward separately from the boss 35 on the left and right upper ends of the leg shield 21. The screw 47 is passed through the boss 46 from the rear and the boss 45
And integrated by fastening to a nut inserted in the nut.

As shown in FIGS. 3 to 5, when the maintenance lid 23 is attached to the front cover body 22, the lower end 48 of the maintenance lid 23 is
In addition, it is located above the mounting hole 37.

As shown in FIG. 5, the maintenance lid 23 and the front cover main body 22 form a continuous curved surface 49. The continuous curved surface 49 has an inclined portion 39a and a stepped portion connected to the opening 39. The parts 36 are respectively retracted to the rear side of the vehicle body.

FIG. 6 shows the leg shield 21 from the rear side. The leg shield 21 is attached to the rear side stay 12b extending rearward from the upper part of the head pipe 4 by a bolt 12c through a mounting hole 21a formed in the upper part of the rear side (FIG. 3). Attachment portions 51 are formed at appropriate intervals on the surrounding flange portion 50, and bosses 52 are formed at corresponding portions of the front cover main body 22 (FIG. 4).
Screws are to be stopped.

A concave portion 53 protruding forward is integrally formed at the center of the rear surface, and an opening opened rearward thereof is opened and closed by a rear lid 54. Reference numeral 55 denotes a hinge. It is.

Next, the operation of this embodiment will be described. First,
In order to attach the front cover body 22 to the vehicle body, the lower stay 24 is provided at two places on the left and right by screws 38 in the mounting hole 37 located below the maintenance opening 30 in the lower front part.
Attach to

Subsequently, the surrounding mounting portion 34 and the boss 52 are combined with the boss 35 and the mounting portion 51 of the leg shield 21 previously mounted on the vehicle body, and integrated with screws from the rear side of the leg shield 21.

Next, the maintenance lid 23 is placed over the maintenance opening 30 and the left and right ends are
1, the engaging protrusion 41 is engaged with the engaging slit 32, and the mounting hole 42 is aligned with the nut 43 of the upper stay 25 and mounted with a screw 44.
Are combined with bosses 46 formed on the upper left and right sides of the leg shield 21 with screws 47 from behind.

Thus, when the maintenance opening 23 is covered with the maintenance lid 23 and the maintenance lid 23 is removed in a reverse procedure, the battery 28 can be maintained through the maintenance opening 30.

As described above, the maintenance lid 23 is not directly attached to the front cover main body 22, so that the opening area of the maintenance opening 30 can be made sufficiently large, and the maintainability can be improved. .

In addition, since the maintenance lid 23 can be fastened to only three places at the upper left and right bosses 45 and the center mounting hole 42, the number of fastenings can be minimized, and the attachment and detachment can be made easier. Therefore, maintainability is also improved in this respect.

In particular, the conventional type, in which the entire front cover is attached and detached, is often fastened to the leg shield and the front fender, but the maintainability is remarkably improved as compared with such a conventional type. I can understand that.

If the long bolt 26 (FIG. 2) is attached instead of the screw 38 and the screw 44, the long bolt 26
Can be used to attach the car 27. However, when attaching the maintenance lid 23, the lower end 48
Is positioned above the car 27, there is no need to form a through hole for the long bolt 26 in the maintenance lid 23 in addition to the mounting hole 42.

Therefore, when the car is not used, the number of mounting holes for the maintenance lid 23 can be minimized, so that the appearance can be improved. At this time, since the mounting hole 37 is formed in the shape of the stepped portion 36 that is recessed from the lower end portion 48, the mounting hole 37 and the screw 38 are more difficult to see, which also contributes to an improvement in appearance.
