As a result, the headlight 30 is also supported using the harness stay 60 while suppressing the lead wires 71, 72, 73 from fluttering due to the rotation of the handle 9 from side to side, so that an increase in the number of parts can be suppressed. .

  The harness stay 60 extends from the pair of left and right frame portions 61 and 61 extending in the vertical direction behind the headlight 30 and the pair of left and right frame portions 61 and 61 to support the headlight 30. Brackets 61b and 61b are provided. The pair of left and right frame parts 61 and 61 have overhanging parts 61c and 61c projecting laterally at intermediate positions, and the brackets 61b and 61b are provided on the overhanging parts 61c and 61c. Accordingly, the headlight 30 having a wider width than the distance between the frame portions 61 and 61 can be stably supported.

  In the motorcycle 1, the wire laid from the handle 9 located above the steering head 21 toward the device located behind the handle 9 (in the above description, the clutch 2 a, the throttle body 14, and the choke). 76, 77, 78. The harness stay 60 holds the switch leads 72 and 73 together with the wires 76, 77 and 78. As a result, the harness stay 60 is used to hold the wires 76, 77, 78 while suppressing the flapping of the switch leads 72, 73 and the wires 76, 77, 78 due to the rotation of the handle 9 from side to side. Increase in the number of parts can be suppressed.

  In addition, the motorcycle 1 includes an oil hose 81 extending downward from the handle 9 located above the steering head 21. The harness stay 60 holds the switch lead 73 together with the oil hose 81. As a result, the oil hose 81 is held by using the harness stay 60 that supports the lead wire 73 while suppressing the switch lead wire 73 from fluttering due to the rotation of the handle 9 from side to side, thereby suppressing an increase in the number of parts. I can do it.

  The present invention is not limited to the motorcycle 1 described above, and various modifications can be made. For example, in the above description, the switch lead wires 72 and 73 and the instrument lead wire 71 are laid so as to extend downward on the left and right sides of the valve 31. However, for example, when the levers 12L and 12R are provided with a switch (for example, a stop switch or a clutch switch) that is turned on / off according to the operation thereof, the lead wires of these switches are connected to the valve 31. It may be laid so as to extend downward on the left and right sides.

  Further, although the battery 49 and the relay units 46 and 48 have been described as examples of the electrical components disposed behind the handle 9, the electrical components disposed behind the handle 9 are not limited thereto. For example, a control circuit that includes a CPU (Central processing unit) and controls the entire vehicle body may be disposed below the seat 11. And the lead wires of various electrical components provided on the handle 9 may be connected to the control circuit.
