The sub-carrier 26 is a member used as a rear carrier when the cabin is formed. The surface of the sub-carrier 26 is a substantially horizontal flat surface having an area capable of supporting articles of a size which can be usually transported. I have.

At the protruding end of the support projection 25, one end of a base 30 also serving as a rear carrier is swingably supported.

The base portion 30 is a member having a sufficient thickness and rigidity of a substantially rectangular shape in plan view having a flat portion having the same shape as the sub-carrier 26 so that it can be used as a rear carrier when the cabin is stored.

The base portion 30 is swingable between an upright position (FIG. 4) used for forming the cabin and a falling position (FIG. 1) used as a rear carrier for housing the cabin.

A base end portion 33 of a pillar body 32 having a substantially rectangular ring shape is swingably attached to the swing end 31 of the base portion 30, and the base end portion 33 is a swing end 31. The rotation is restricted by a screw 34.

The other end of the pillar body 32 is connected to a roof support 35.
When the cabin is housed in the cabin as shown by the solid line, the length of the cabin is such that it rotates around the base end 33 supported by the swing end 31 and reaches below the seat 22.

The roof support portion 35 is fixed at one end of a soft-top type roof 36 formed of a flexible and waterproof plastic material or the like, and serves as a roof storage portion when the cabin is stored.

At the other end 37 of the roof 36, a suitable fitting 38 such as a hook is provided (FIG. 4), and a mating member 11c such as a hook formed on the upper end 11b of the wind screen 11 is provided.
(Fig. 3).

Next, the operation of the present embodiment will be described. FIG.
The windscreen 1
As shown in FIG. 5, 1 is stored on the back side of the front cover / lid 10.

At this time, the windscreen 11 is fixed to the storage position by the elasticity of the reversing spring 15 and is kept in this state.

When the front cover / lid 10 is fully opened (FIGS. 2 and 5) and the hand control lever 16 is pulled down, the parallel link 12 pivots upward against the reversing spring 15 so that the wind screen 11 is rotated. Moves upward (FIG. 3).

When the wind screen 11 moves by a predetermined amount,
When the reversing spring 15 reaches the use position above the dead center, the windscreen 11 moves to the reversing spring 15.
The movement is stopped by the resilience of, and is fixed at the use position, and this state is maintained.

Subsequently, the front cover / lid 10 is also used.
Is closed to a position substantially continuous with the windscreen 11 (FIG. 4), and the sliding lid 17 is moved upward to form between the lower end 11a of the windscreen 11 and the upper end 10a of the front cover / lid 10. Cover the gap (Figure 6).

The sliding lid 17 is moved in a state where it is smoothly and positioned by the guide 18, whereby the window screen 11 shown in FIGS. 4 and 6 is used.

Thereafter, as shown in FIG. 4, the roof 36, which has been folded in advance by erecting the base portion 30 and the pillar main body portion 32, is opened, and the other end 37 is attached to the upper end 11 b of the windscreen 11 with a fixture 38. When mounted on the mating member 11c (FIG. 3), a covered cabin is easily formed above the vehicle body. Note that the storage from this state may be performed in a reverse procedure.

As described above, since the wind screen 11 is moved up and down via the parallel link 12 consisting of the pair of upper and lower links 13 and 14, the vertical movement distance can be made sufficiently long, and members for forming the cabin can be provided. Can be projected upward sufficiently long.

Moreover, during this vertical movement, the windscreen 11 moves in parallel, and its inclination does not change irregularly. Therefore, if the front cover / lid 10 is opened by a predetermined angle in advance (FIGS. 2, 3 and 5), the windscreen 11 can be easily and quickly moved up and down with one touch without interfering with other parts, thereby improving operability.

In addition, since the hand control lever 16 is provided, by operating the hand control lever 16, the wind screen 11 can be moved up and down more easily and quickly by one-touch operation, and the operability is further improved.

Further, since the reversing spring 15 is provided on the parallel link 12, the wind screen 11 can be held in a fixed state at the storage position or the use position without using a special fixing means such as a lock. It is possible to prevent rattling and to reduce labor and cost for fixing.

Further, a part of the front cover 7 is formed as a front cover / lid 10 which can be freely opened and closed, and the windscreen 11 is accommodated on the back side thereof, so that the entire front cover 7 can be made relatively thin.

The present invention can be variously modified without being limited to the above embodiment. For example, the link mechanism may have at least one pair of link members in the vertical direction, and it is not always necessary to use only one pair of link members. It does not need to be formed by using, and may be only one of the right and left sides.

Further, if necessary, the link member may be made unequal in length, instead of the parallel link, so that the wind screen 11 has a special movement trajectory.

The present invention can be applied not only to motorcycles but also to motorcycles having a retractable cabin, and can be used for storing a windscreen alone, irrespective of the retractable cabin.
