Moreover, since the front part of the rear top cover 36 covers the fastening location to both main frame side covers 31L, 31R of the rear part of the front top cover 35, and is engaged with the rear part of the front top cover 35, By covering the fastening points to both main frame side covers 31L and 31R of the rear part of the front upper cover 35 with the rear upper cover 36, the appearance is improved and the detachable operation of the rear upper cover 36 is easy. In this way, maintenance work can be further facilitated.

By the way, the outer surface of a pair of left and right rear side covers 38L and 38R is divided into the coating area Z3 and the first and second non-coating areas Zl and Z2. For this reason, even if the rear side covers 38L and 38R are not constituted by a plurality of cover parts, by using a part of the rear side covers 38L and 38R as an unpainted cover, an increase in the number of parts is suppressed and the cost is reduced. By the way, a superior color effect can be obtained by design, and a wound and a dirt can be prevented from seeing. In addition, the division of the coating area Z3 and the non-painting areas Zl and Z2 can be freely changed.

In addition, the 1st non-painting area | region Zl is set as the part located in the lower part of the front part of the tandem seat 26 in both rear side covers 38L and 38R, and of both rear side covers 38L and 38R. As the lower part of the front part, the upper part rather than the foot step 18 is set to the 2nd non-painting area | region Z2, and the fine wrinkles 86 are attached to those non-painting areas Zl and Z2.

That is, in both rear side covers 38L and 38R, the first and second non-painted areas Zl and Z2 are disposed at portions where the driver's feet are easy to reach during lifting and lowering, and the driver's feet are placed in the first position. And the color of the rear side covers 38L and 38R is prevented from changing even when the second unpainted areas Zl and Z2 are touched and the unpainted areas Zl and Z2 are damaged or dirty. It can make it hard to see a wound or dirt.

In addition, the driver's foot is easily in contact with the outer surface of the front upper cover 35 in the upper cover 34 at the time of getting on and off the tandem seat 26, but the outer surface of the front upper cover 35 is fine-lined pattern 86. It remains unpainted with). For this reason, even if a foot touches the outer surface of the front upper cover 35, the outer surface of the front upper cover 35 may be damaged or dirty, and the color of the front upper cover 35 is prevented from changing. It may be hard to notice a wound and a dirt. In addition, when scratches or dirt on the outer surface of the front top cover 35 become conspicuous, the front top cover 35 can be easily removed from both main frame side covers 31L and 31R, and the front top cover ( 35) can be exchanged simply.

As mentioned above, although the Example of this invention was described, this invention is not limited to the said Example, It is possible to perform various design changes, without deviating from this invention described in the claim.

For example, in the above embodiment, two unpainted areas Zl and Z2 are set in the rear side covers 38L and 38R, but three or more unpainted areas are provided in the rear side covers 38L and 38R. It may be set. In the above embodiment, the rear side covers 38L and 38R are made of synthetic resin, but the rear side covers may be formed of other materials such as metal plates.
