Similarly, one end of a third wire (drive transmission member) 97 is connected to the other end of the connecting member 95. The other end of the third wire 97 is connected to the rear portion 83 of the lower wing 81.
When the motor 91 is driven, the first wire 94 is wound up. When the first wire 94 is wound, the connecting member 95 slides and the second wire 96 and the third wire 97 are pulled. When the wires 94 and 97 are pulled, the upper and lower wings 80 and 81 are pulled inward in the vehicle width direction against the elastic force of the respective return springs 89 and rotated to the storage position (see FIG. 5).

FIG. 10 is a cross-sectional view taken along the line XX of FIG. 1 and is a view for explaining the arrangement of the drive mechanism 90.
The motor 91 is disposed between the radiator 20 and the engine 10. The core 21 of the radiator 20 has a cross-sectional arch shape with the front opened, and the left and right tanks 22 </ b> L and 22 </ b> R are positioned in front of the core 21. The tanks 22 </ b> L and 22 </ b> R are further away from the engine 10 than the core 21, and a space S is generated between the radiator 20 and the engine hanger portion 24 of the main frame 15. Using this space S, motors 91 are arranged on the left and right.

The wires 94, 96, and 97 (see FIG. 9) are slidably supported along the guide hoses 94a, 96a, and 97a. The guide hoses 94a, 96a, 97a are fixed to the vehicle body frame F.
As shown in FIG. 10, the guide hose 94a of the first wire 94 is fixed between the radiator 20 and the inner cover 60 at the left and right ends 94a1 on the motor 91 side.
As shown in FIGS. 4 and 5, the guide hose 96 a of the second wire 96 has an end portion 96 a 1 on the wing 80 side fixed to the inner side in the vehicle width direction of the rear end portion of the long hole 70.

The ECU 93 (see FIG. 9) controls the drive mechanism 90 based on conditions set in advance based on vehicle speed, vehicle body inclination, and the like.
When the ECU 93 determines that the down force is unnecessary, the motor 91 is driven. When the motor 91 is driven, the wires 94, 96, and 97 are pulled. When the wires 94, 96, 97 are pulled, the wings 80, 81 move to the storage position against the elastic force of the return spring 89. The wings 80 and 81 are held at the storage position while the motor 91 is driven.

  When the ECU 93 determines that down force is necessary, the driving of the motor 91 is stopped. When the drive of the motor 91 is stopped, the wings 80 and 81 are moved to the operating position while pulling the wires 94, 96, and 97 by the urging force of the return spring 89. The wings 80 and 81 are held in the operating position.

When the motorcycle 1 travels, traveling wind is taken into the air guide path 67.
At this time, it is possible to obtain a down force by moving the wings 80 and 81 to the operating position. Therefore, for example, it is possible to turn with the grip force improved. Further, the air resistance of the traveling wind can be reduced by moving the wings 80 and 81 to the storage position. Therefore, for example, it is possible to travel straight ahead at high speed with reduced air resistance.

  As described above, according to the present embodiment to which the present invention is applied, the head pipe 14, the main frame 15 extending rearward from the head pipe 14, and the side cover 52 covering the main frame 15 from the left and right are provided. In the saddle-ride type vehicle, the side cover 52 includes an inner cover 60 and an outer cover 66 that covers the inner cover 60 from the outside. The inner cover 60 and the outer cover 66 form an air guide path 67, and a movable wing. 80 and 81 are provided between the inner cover 60 and the outer cover 66 inside the air guide path 67. According to this configuration, by providing the movable wings 80 and 81 between the side covers 52, it is possible to increase down force while utilizing existing parts such as the side covers 52. When downforce is not necessary, the air resistance can be reduced by changing the flow path with the movable wings 80 and 81. Further, since the movable wings 80 and 81 are disposed in the air guide path 67 formed by the inner cover 60 and the outer cover 66, the movable wings 80 and 81 do not come into contact with the outside of the vehicle, and the design is good. Can be solved.

  In the present embodiment, the wings 80 and 81 are plate members having a shaft hole 84 that constitutes a rotating shaft in front of the vehicle body, and the inner cover 60 has elongated holes 70 and 71 extending in the front-rear direction. 81 rotates around the shaft hole 84 and passes through the long holes 70 and 71 to be accommodated in the side cover. Therefore, when down force is unnecessary, it can be accommodated by rotating the wings 80 and 81.

  Further, in the present embodiment, there is a recess 69 inside the outer cover 66, and a protrusion 88 constituting the outer ends of the wings 80 and 81 is fitted in the recess 69. Therefore, the wings 80 and 81 can be easily positioned.

  Further, in the present embodiment, the inner cover 60 has a bulging portion 72, a long hole rear portion 72 a through which the wings 80 and 81 pass through the bulging portion 72, and the bulging portion 72 includes the wings 80 and 81. It is a series. Therefore, since the bulging part 72 functions as a part of the wings 80 and 81, the shape freedom degree of the wings 80 and 81 can be raised.

  In the present embodiment, the wings 80 and 81 are driven by a motor 91, and the motor 91 is disposed behind the radiator 20. Therefore, the wings 80 and 81 can be electrically controlled.

  Further, in the present embodiment, at least one of the wings 80 and 81 is disposed at the maximum portion 68 constituting the position where the width of the air guide path 67 is the widest. Therefore, it is easy to obtain downforce.

The above-described embodiment is merely an aspect of the present invention, and can be arbitrarily modified and applied without departing from the gist of the present invention.
Although the left wings 80 and 81 are driven by the left motor 91 and the right wings 80 and 81 are driven by the right motor 91, one motor may be used. In this case, it is possible to transmit the drive to the left and right wings 80 and 81 by pulling a plurality of wires through the connecting member, and one motor is provided on the left side as shown in FIG. You may arrange | position in the space S1 between the radiator fan 23L and the right radiator fan 23R.
Although the configuration in which the wings (air flow path changing devices) 80 and 81 rotate has been described, the configuration may not be such that the wings rotate. For example, the wings (air flow path changing devices) 80 and 81 may be configured to slide between the operating position and the storage position, and the air flow path changing device may be a shutter.

The drive mechanism 90 has been described as being driven by the motor 91, but may not be the motor 91. For example, the drive source may be a solenoid.
Although the wings 80 and 81 have been described as having the shaft hole 84 as the rotation axis, a configuration in which the shaft formed integrally with the wing is used as the rotation shaft instead of the shaft hole 84 may be used. That is, a structure in which the shaft formed integrally with the wings 80 and 81 is rotatably supported by the vehicle body frame F may be employed.
The wings 80 and 81 may be driven separately on the left and right.
Although the wings 80 and 81 have been described as being controlled by the ECU 93, for example, an operation button may be provided on the handle 30 and the motor 91 may be driven by turning the operation button on and off.
