Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scooter type motorcycle having a luggage storage box such as a basket in a front portion of a vehicle body.

[0002]

2. Description of the Related Art In a conventional scooter type motorcycle of this type, a basket is arranged in front of a cover for covering a head pipe.

The cover is formed such that the front wall thereof gradually protrudes forward as it goes downward from the lower portion of the handle, and the basket is provided along the inclined front wall. Further, a headlight was arranged on the handle portion.

[0004]

However, the above-mentioned conventional scooter type motorcycle has a problem that the storage capacity in the basket is small. This is because the basket is attached along the front wall of the cover that is inclined downward to the front, so that the opening width becomes gradually narrower as it goes downward from the upper loading / unloading port.

If the size of the basket is simply increased to increase the storage capacity, the center of gravity of the luggage will be separated from the center of gravity of the vehicle.

Further, since the headlight is located above the basket, this also restricts the upper edge of the loaded luggage.

[0007]

In the scooter type motorcycle according to the present invention, a headlight is arranged below a front bottom portion of a luggage storage box, and a rear bottom portion of the luggage storage box is placed behind the headlight. It has been extended.

[0008]

Function: The headlight is positioned lower than the luggage. The space behind the headlights is used as a luggage storage space.
