Description

Description: TECHNICAL FIELD The present invention relates to a scooter type vehicle having an article storage space formed below a seat.

[Conventional technology]

A scooter is widely used as a foot for the masses such as commuting to work and shopping in recent years because a scooter can be seated on a chair and can be easily boarded by women and young people.

In this type of scooter, a footrest portion is formed between a handle and a seat, and a unit swing type engine having rear wheels supported at a rear portion is disposed behind the footrest portion and below the seat.

As a conventional scooter, there is a scooter in which the lower side of the seat is covered with a vehicle body cover and an article storage space opened and closed by the seat is formed in the vehicle body cover. In this scooter, the seat is generally rotatable about the front end of the seat as a fulcrum.

[Problems to be Solved by the Invention]

However, if the seat is opened and closed by using the front end as a fulcrum in this way, the large hinge and the seat itself become an obstacle when the seat is opened and put in and out of articles, inspection, refueling, etc. Will end up.

Below the rear part of the vehicle body cover, there is a large-diameter rear wheel that is located in the area where the vertical swing range of the unit swing engine is the largest, and the lower end of the vehicle body cover tends to rise toward the rear. Therefore, in the vehicle body cover, a space in which the front side portion thereof is most vertically concentrated is obtained.

That is, in the conventional scooter, this space cannot be effectively used due to the hinge and the seat itself as described above.

In order to eliminate such a problem, it is conceivable to raise the hinge position or position it in front so that the seat and the hinge position are far away from the space with the seat open. However, in such a case, the seat height becomes high, the seat cushion thickness is reduced, and the seat largely projects into the footrest space, which adversely affects the riding condition of the occupant.

[Means for Solving the Problems]

The present invention has been made in view of the above circumstances, and provides a scooter type vehicle that can be utilized as an article storage space without lowering the riding condition of an occupant, where the seat lower part where a large gathered space can be obtained is obtained. is there. In a scooter type vehicle according to the present invention, a rear end portion of a seat is pivotally attached to a rear portion of a vehicle body frame, and a front portion of the seat extends upward from a vehicle body frame to an upper edge of a vehicle body cover. A seat lock is provided in the seat portion, and a support member is provided behind the seat lock, and seat load receivers are arranged on the left and right sides of the seat lock, and an article storage space is formed in the vehicle body cover below the seat front portion. It was done.

[Action]

The seat pivot portion is positioned behind the article storage space, and when the seat is open, the seat itself is positioned rearward from the article storage space.

The 18 and the oil tank 19 can be supported by using both support frames 11 and 12 provided in front of and behind them to support the seat 3. Therefore, the number of members accommodated under the seat can be reduced. Moreover, both tanks 18,19
Since it is not necessary to project a member for supporting the tank to the side of the tank, the side surface of the tank can be directly exposed to the inner surface of the side cover 21 and can be brought close to each other.

Furthermore, in the embodiment, since the fuel tank 18 and the oil tank 19 are engaged with each other on the inner side, the oil tank 19
Is elastically held by the fuel tank 18 with respect to its downward and inward movement. Fuel tank 18
The oil tank for its upward and inward movement
19 It is elastically held by utilizing its own elasticity. As a result, both tanks 18 and 19 can be integrally supported to reduce the number of tank mounting points, so that the number of parts can be reduced and the mounting work can be simplified.

In addition, the heavy fuel tank 18 is not fixed, but is elastically held through a cushioning material that is in pressure contact with the tank, so that vibration resistance and impact resistance can be improved.

〔The invention's effect〕

As described above, in the scooter type vehicle according to the present invention, the seat rear end portion is pivotally attached to the rear portion of the vehicle body frame,
Since the article storage space is formed in the vehicle body cover below the seat front portion, the lower portion of the seat front portion where a large and cohesive space can be obtained can be utilized as the article storage space.

Further, since the seat pivot portion is positioned behind the article storage space, and the seat itself is positioned rearward of the article storage space when the seat is open, the upper part of the space is largely opened and the work is performed. It is highly likely. Moreover,
When the seat in the open state is separated from the space, the seat pivot portion is positioned rearward of the space, so that the seating surface of the seat becomes high, the seat cushion thickness becomes thin, and the seat largely projects into the footrest space. Nor.

Further, since the seat lock is provided at the front end of the support member, the front end of the seat can be formed as narrow as possible, and even if the occupant rides with both feet aligned on the low floor, he / she can get on the vehicle. There is no loss of posture. Moreover, since the seat load receivers are arranged on the left and right sides behind the seat lock, the seat front portion can be reliably supported even if the front end portion of the seat is formed narrow as described above. Further, since the seat lock and the load receiver are provided on the same support member, there is an effect that the relative positions of the two are unlikely to shift and the engagement by the seat lock can be reliably performed.
