The storage box 15 and the fuel tank 16 are covered with a tandem type riding seat 17 that is rotatably supported at the front portion of the storage box 15.

  The vehicle body frame 5 is covered with a vehicle body cover 18 made of synthetic resin. The vehicle body cover 18 is connected to the front cover 19 that covers the head pipe 8 from the front, and the front cover 19 is connected to the driver's feet. A leg shield 20 that covers the front, a step floor 21 that continues to the lower part of the leg shield 20 so as to place the rider's feet, and a side cover 22 that continues to the step floor 21 and covers the rear of the vehicle body from both sides are provided.

  In FIG. 2, the gear ratio of the electronically controlled transmission included in the power unit P is determined by the shift operation member 24 </ b> A and the shift operation for upshifting by the left hand holding the grip 23 provided at the end of the steering handle 7, for example, the left end. It can be changed by manual operation of the member 25.

  The shift operation member 24A includes a first shift down operation portion 24a that can be manually operated to the downshift side during non-brake operation, and a second downshift that can be manually operated to the downshift side during brake operation. And an operation unit 24b.

  By the way, in front of the left end portion of the steering handle 7, a brake lever 29 is rotatably supported by a bracket 27 provided on a holder 26 attached to the steering handle 7 via a first support shaft 28. The rear wheel brake can be braked by operating the brake lever 29. The brake lever 29 is an interlocking brake that operates the front wheel brake by operating the brake lever 29. It may constitute a part of the apparatus.

  The shift operation member 24A is rotatably supported by the holder 26 via a second support shaft 30 having an axis parallel to the first support shaft 28 and disposed at a position offset from the first support shaft 28. The In addition, the first downshift operation portion 24a of the shift operation member 24A can be operated with the index finger F2 while holding the grip 23 with the thumb F1, the middle finger F3, the ring finger F4, and the little finger F5 when the brake lever 29 is not operated. However, it is disposed between the grip 23 and the brake lever 29 in the vehicle longitudinal direction. Further, the second downshift operation unit 24b can be operated with the index finger F2 while operating the brake lever 29 with the middle finger F3, the ring finger F4, and the little finger F5 with the thumb F1 applied to the grip 23. Arranged forward.

  The shift operation member 24A has a recess 24c between the first shift-down operation unit 24a and the second shift-down operation unit 24b. The recess 24c allows the index finger F2 for operating the first shift-down operation unit 24a to be inserted. Formed as described above.

  The shift operation member 24A includes a neutral position shown in FIG. 2, a shift-down position rotated from the neutral position around the axis of the second support shaft 30 by a predetermined angle counterclockwise in FIG. 2, and the neutral position. It is supported by the holder 26 via the second support shaft 30 so as to be able to rotate between a shift-up position rotated by a predetermined angle clockwise around the axis of the second support shaft 30 in FIG. And is biased toward the neutral position by a spring (not shown).

  By the way, the brake lever 29 rotates around the axis of the first support shaft 28 in the counterclockwise direction of FIG. 2 during the brake operation, and the operating direction of the shift operation member 24A toward the shift down side is the brake The direction of rotation of the brake lever 29 during operation is set in substantially the same direction.

  The shift operation member 25 for up-shifting allows the index finger F2, the middle finger F3, the ring finger F4, and the little finger F5 to be operated forward by the thumb F1 in a state where the index finger F2, the ring finger F4, and the little finger F5 are put on the grip 23. It is arrange | positioned back and is rotatably supported by the holder 26 via the 3rd spindle 31 parallel to the 1st and 2nd spindle 28,30.
