Next, the operation of the upper and lower spoilers 2a and 2b and the posture of each of the upper and lower wing portions 4a and 4b during each operation will be described.
As shown in FIGS. 2 and 3, when the slider 24 of the upper spoiler elevating mechanism 3a is lowered, the upper spoiler 2a is completely stored in the opening 25 and closes the opening 25 provided on the rear body upper surface 7a. The upper wing portion upper surface 32a is substantially at the same level as the rear body upper surface 7a.
When in the stowed position with the opening 25 closed, the upper wing upper surface 32a is designed to form the rear body of the vehicle together with the rear body upper surface 7a. Thus, when the upper wing part 4a of the upper spoiler 2a forms the body of the rear part of the vehicle, the support 40 of the lower spoiler 2b is in the lowest position, and the lower wing part 4b of the lower spoiler 2b is the upper wing part 4a. It is stored in the opening 25 on the lower side and is not visible from the outside of the vehicle (hereinafter, this state is referred to as a storage posture).

As shown in FIGS. 4 and 5, when the ball screw 28 is rotated by the drive motor 30 of the upper spoiler lifting mechanism 3a, the front and rear columns 16F and 16R rise linearly and simultaneously along the longitudinal direction via the slider 24, respectively. As a result, the upper wing portion 4a of the upper spoiler 2a rises while maintaining a predetermined angle (in this case, the angle in the storage posture). The upper wing portion 4a of the upper spoiler 2a rises from the rear body upper surface 7a and has an action posture for rectifying the wind.
As described above, when the upper wing portion 4a is changed from the stowed posture to the working posture by raising the front and rear columns 16F and 16R, the upper spoiler lifting mechanism 3a linearly raises the front and rear columns 16F and 16R in the longitudinal direction. Therefore, the ascending orbits of the front and rear columns 16F and 16R do not protrude into the front and rear space portion A where the front and rear columns 16F and 16R are not installed in the rear body 7.

Therefore, when installing the front and rear columns 16F and 16R of the rear spoiler device 1A in the rear body 7, a moving space for raising (moving) the front and rear columns 16F and 16R is newly provided separately from the front and rear installation spaces of the front and rear columns 16F and 16R. If the installation space for installing the interior of the rear body 7 is secured, the upper wing 4a is supported by the front and rear struts 16F and 16R while supporting the upper wing 4a. Can be moved up and down.
When the drive motor 44 of the lower spoiler elevating mechanism 3b is driven at the same time as or slightly behind the ascending operation of the upper wing portion 4a of the upper spoiler 2a, the cable 43 pushes the column 40 of the lower spoiler 2b and stores it in the opening 25. The lower wing part 4b of the lower spoiler 2b that has been projected is protruded from the opening 25, and the upper surface 32b of the lower wing part 4b of the lower spoiler 2b is exposed from the rear body upper surface 7a in a raised manner.

That is, the lower spoiler 2b is in an action posture in which the front end of the lower wing upper surface 32b is positioned at substantially the same height as the rear body upper surface 7a and the rear end rises from the rear body upper surface 7a. The air flowing in the vehicle can be rectified, and the downforce can be given to the vehicle by the resistance of the air rectification.
When the upper and lower spoilers 2a and 2b are in the working posture, when the drive motor 44 is driven and the support 40 of the lower spoiler 2b is pulled by the cable 43, the lower spoiler 2b is lowered and the lower wing 4b of the lower spoiler 2b is opened. 25 can be stored again. Further, when the drive motor 30 is driven to lower the slider 24, the opening 25 can be closed by the upper wing 4a of the upper spoiler 2a.

When the upper and lower spoilers 2a and 2b are moved up and down, the drive motors 30 and 44 of the upper and lower spoiler lifting mechanisms 3a and 3b may be driven simultaneously or individually. Further, the upper spoiler 2a may be set to the action posture at the midway of the lifting stroke, and at the same time, the lower spoiler 2b can be set to the action posture.
As shown in FIG. 4, when the ball nut 36 is rotated via the drive motor 37 of the angle changing mechanism 35 with the upper and lower wings 4a and 4b of the upper and lower spoilers 2a and 2b in the working posture, the front column 16F is fixed. The rear strut 16R can be raised with the rear strut 16R raised, and the upper spoiler 2a rotates rearward (upward) with the horizontal shaft 18 as a fulcrum as the rear strut 16R rises. The angle can be changed.

The drive motor 37 of the angle changing mechanism 35 can be driven independently of the drive motors 30 and 44 of the up-and-down lift mechanisms 3a and 3b, and the upper spoiler 2a has an upper wing portion 4a with an opening. Even when 25 is closed, it is possible to change the angle of the upper wing portion 4a so that a part of the upper wing portion 4a (the rear portion of the upper wing portion 4a) protrudes from the rear body upper surface 7a. Moreover, the angle of the upper wing part 4a can be changed even while the upper wing part 4a of the upper spoiler 2a is moved up and down.
6 and 7 show a rear spoiler device 1B according to a second embodiment of the present invention. In the second embodiment, the angle changing mechanism 35 and the upper spoiler elevating mechanism 3a that elevates and lowers the upper spoiler 2a are changed.

The lower ends of the front and rear struts 16F and 16R are fixed to the ball nuts 50 and 52, respectively. The front and rear struts 16F and 16R are inserted into the upper base member 11U and supported so as to be movable up and down, and the stroke of the rear strut 16R is set longer than the stroke of the front strut 16F.

The drive motors 30a and 30b of the front and rear lifting means 47 and 48 can be driven individually or simultaneously. When the drive motors 30a and 30b are driven simultaneously, the ball screws 51 and 53 of the front and rear elevating means 47 and 48 rotate at the same time, so that both ball nuts 50 and 53 move up and down at the same speed (the front and rear struts 16F and 16R are at the same rate). Therefore, the upper wing portion 4a moves up and down while keeping the angle unchanged.
When the upper wing portion 4a is raised from the lowered position, when the stopper 54 protruding upward from the ball nut 50 comes into contact with the upper base member 11U, the drive motor 30a and the ball screw 53 that rotate the ball screw 51 are moved. The rotating drive motor 30b stops at the same time and stops rising.

When the ball nut 50 that raises and lowers the front column 16F is in the raised position (when the stopper 54 is in contact with the upper base member 11U), the ball nut 52 that raises and lowers the rear column 16R is not in contact with the upper base member 11U. Instead, it can move upward from the ball nut 50 until it comes into contact with the upper base member 11U by a longer stroke.
Therefore, when the drive motor 30b of the rear elevating means 48 is driven while the drive motor 30a of the front elevating means 47 is stopped and the ball nut 52 is moved above the ball nut 50, the rear strut 16R becomes the front strut 16F. On the other hand, the angle of the acting posture of the upper wing upper surface 32a can be changed.

  In the second embodiment, the upper spoiler lifting mechanism 3a is configured to drive the front and rear lifting means 47 and 48 simultaneously, and the angle changing mechanism 35 is configured to drive only the rear lifting means 48 individually. For example, first, only the drive motor 30b of the rear lifting / lowering means 48 is driven in the state where the drive motor 30a of the front lifting / lowering means 47 is stopped from the stowed position of FIG. The angle is changed, and the upper and lower lifting / lowering means 47 and 48 are operated from the posture to raise the upper wing portion 4a to the required height, and the action posture when the upper wing portion is raised is operated to operate the rear raising / lowering means 48 and the upper wing portion upper surface 32a. You can change the angle.
