DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motorcycle provided with a windscreen capable of moving up and down (hereinafter referred to as a windscreen). The windscreen is provided with a wiper, and the wiper is moved up and down in conjunction with the windscreen. The present invention also relates to a front windscreen device for a motorcycle capable of securing a large vertical stroke of the windscreen while having a wiper.

A motorcycle of a scooter type having a detachable roof has been proposed in Japanese Patent Publication No. 3-52396. In this type of motorcycle, the front end of the detachable roof is supported by the windscreen, so it must be held at a height that does not interfere with the occupant's head when running on a roof with a roof. The windscreen must be set at a height that does not interfere with the occupant's head in relation to the roof. Therefore, the position of the upper end of the windscreen is set higher than the head of the occupant. In such a motorcycle with a roof, the upper end of the windscreen is located in front of the occupant and higher than the head of the occupant, even when the motorcycle runs with the roof removed.

For this reason, even when the roof screen is removed and the vehicle travels without a canopy, the windscreen is located higher than the occupant's head.
If the height of the windscreen can be kept low, for example, if the windscreen can be lowered below the line of sight of the occupant, light traveling can be enjoyed. Therefore, in a motorcycle equipped with a windscreen,
A motorcycle in which a windscreen is moved up and down to adjust its height is disclosed in Japanese Patent Publication No. 3-52391. This technology is a non-topped motorcycle with no roof, in which a windscreen is moved up and down to adjust its height so as to be able to meet the occupant's preference.

[0004]

SUMMARY OF THE INVENTION Folding type (removable type)
In a motorcycle equipped with a roof, if the height of the windscreen is moved up and down according to the traveling conditions, such as canopy traveling in a covered state during rainy weather traveling, canopy traveling with the roof removed, The preferred height of the windscreen according to the driving conditions is obtained. Therefore, it is desirable to adjust the height of the windscreen by moving it up and down in accordance with canopy travel and canopy-free travel. On the other hand, since the canopy travel is performed at the time of rainfall, it is desirable to attach a wiper device for the purpose of sweeping out the adhesion of water droplets to the windscreen due to the rainy weather travel. By the way, when the windscreen is moved up and down in a state where the wiper device is provided, the wiper device may restrict the vertical movement of the windscreen.

[0005] When the windscreen is configured to be movable up and down and a wiper device is provided, there are the following problems. When the wiper device is fixed to the vehicle body and only the windscreen is configured to be movable up and down, it is necessary to install the wiper device at a position that does not affect the vertical movement of the windscreen. Therefore, it is necessary to arrange the wiper device at a lower limit position of the windscreen where the wiper blade does not protrude upward from the upper end of the windscreen. According to this, at the upper limit position of the windscreen, the wiper blade is at a lower position,
It may be difficult to sweep out the high area of the windscreen, resulting in a small sweeping area of the wiper blade and a reduced sweeping function.

Therefore, it is conceivable that the windscreen and the wiper device are integrated, and the windscreen device is moved down together with the windscreen. However, according to this, the amount of downward movement (downward stroke) of the windscreen cannot be large because the wiper device is in the way. In addition, it is necessary to provide a wind screen vertical movement mechanism on the wind screen and to integrally incorporate the wiper device into the wind screen, which complicates the structure of the wind screen. Furthermore, the weight of the windscreen device is always applied to the windscreen, and the windscreen moves up and down including the weight of the windscreen device, so that the output of the motor for moving the windscreen up and down becomes large, and the motor becomes large. Sometimes.

In a motorcycle, the front of the motorcycle is narrow,
It is not preferable to consider installing a large-capacity motor in a limited space. In addition to the above, a drive mechanism including a motor of a wiper device is provided between a windshield and a front cover, which is a front external member of a motorcycle, because the appearance of the wiper is poor when the wiper is exposed outside the front cover. There is also a problem that it is desirable to store it, and these problems have problems such as restrictions on space as described above.

Incidentally, the aforementioned Japanese Patent Publication No. 3-52391.
No. is a technology of moving the windscreen of a motorcycle without a canopy up and down, but the technology disclosed herein is to provide a motor on the vehicle body side and a pair of left and right screw rods driven by the motor.

When the windscreen vertical drive mechanism having the above-described structure is used and the wiper device is installed as described above, the windscreen drive motor is located at the upper position. There is a risk of interference with the motor of the wiper device which needs to be arranged above the motor. On the other hand, if the windscreen driving motor is disposed, for example, below, the driving motor may interfere with the lowering of the windscreen, the amount of downward movement of the windscreen is reduced, and the vertical stroke of the windscreen is increased. There is a defect that you can not.
