JP 2001-171580 A

  However, in the device disclosed in Patent Document 1, the storage capacity of the storage box must be sacrificed in order to secure the battery placement space, and the center cover that also serves as a maintenance lid covers the side surface of the battery. Therefore, in order to perform maintenance of terminals normally arranged on the upper surface of the battery, troubles such as taking out the battery are required. Therefore, in order to increase the capacity of the storage box and to enable maintenance work from above to improve maintenance, it is conceivable to store the battery upright in the floor tunnel, but the center that forms part of the body frame In the case where the frame is disposed at the center upper portion in the floor tunnel portion, the center frame impedes the maintainability of the battery when the battery is disposed below the center frame. In addition, when the battery is disposed above the center frame, there is a problem that the height of the floor tunnel portion becomes high and it becomes difficult for passengers to get on and off.

  The present invention has been made in view of such circumstances, and even if the center frame constituting a part of the vehicle body frame accommodates the battery in the floor tunnel portion disposed at the center upper portion, the floor tunnel portion is high. It is an object of the present invention to provide a scooter type motorcycle having improved battery maintainability while avoiding this.

  In order to achieve the above object, a first aspect of the present invention is a vehicle body frame having a head pipe at a front end for movably supporting a front fork that pivotally supports a front wheel, and a part of a power unit supported by the vehicle body frame. A floor tunnel portion that is disposed between a pair of left and right footrests on which the occupant places his feet and is raised upward, and a single center frame constituting a part of the vehicle body frame, In the scooter type motorcycle disposed in the floor tunnel part above the footrest part, the battery having a rectangular parallelepiped shape has a plane including the shortest side among the planes constituting the outer surface of the front and rear of the vehicle body frame. The floor tunnel that is supported on the center frame in a posture facing the left and right and along a substantially vertical direction and covers the battery Wherein the portion disposed above the battery, characterized in that Menten'nansu hole that is closed to be openable and closable maintenance lid is provided within the.

  According to a second aspect of the present invention, in addition to the configuration of the first aspect of the invention, the pair of terminals included in the battery is the highest in a side view when the battery supported by the center frame is viewed from the side. As described above, the battery is arranged to be inclined.

  According to a third aspect of the present invention, in addition to the configuration of the first or second aspect of the present invention, a control unit that is disposed at substantially the same height as the battery in front of the battery constitutes a part of the body frame. In this way, it is supported by the rear portion of the down tube along the longitudinal direction of the down tube suspended from the head pipe.

  According to a fourth aspect of the invention, in addition to the configuration of the first aspect of the invention, a reserve tank having a water supply port directed to the maintenance hole is disposed around the battery. It is characterized by.

  Furthermore, in the invention according to claim 5, in addition to the configuration of the invention according to any one of claims 1 to 4, a fuel tank is disposed below the battery in the floor tunnel portion, and a fuel filler port of the fuel tank is provided. The floor tunnel portion is disposed toward one of both side surfaces.

  According to the first aspect of the present invention, the battery having a rectangular parallelepiped shape is supported on the center frame in such a posture that the plane including the shortest side faces the front and rear and the left and right of the body frame and is substantially along the vertical direction. Therefore, even if the battery is stored in the floor tunnel portion, it is possible to avoid the height of the floor tunnel portion from being increased, and a maintenance hole is provided in a portion of the floor tunnel portion disposed above the battery. Therefore, the maintainability of the battery can be improved.

  According to the invention described in claim 2, since the battery is inclined so that the terminal of the battery is located at the highest position in a side view, the maintenance work can be facilitated by arranging the terminal at a high position. .

  According to the invention described in claim 3, since the control unit is supported in the rear part of the down tube in front of the battery, the control unit can be arranged close to the battery, and the electric wire connecting the battery and the control unit can be provided. Can be shortened.

  According to the fourth aspect of the present invention, since the reserve tank with the water supply port directed to the maintenance hole is arranged around the battery, the maintenance hole can be shared by the battery and the reserve tank.

  According to the fifth aspect of the present invention, the fuel tank filler port disposed below the battery is disposed toward one of both side surfaces of the floor tunnel portion, so that it is affected by the battery above the fuel tank. The fuel tank can be refueled without any trouble.
