The notched window 13a does not obstruct the view secured.

On the other hand, reference numeral 16 denotes a headlight provided at a front end portion of the traveling vehicle body 1. The headlight 16 illuminates the front of the vehicle body through an opening 13b formed in a lower left portion of the front panel 13. For this reason, it is mounted on the inner surface of the front panel 13 via a bracket 17 having a rectangular tube shape, and the opening 13b is covered by a light cover 18. The light cover 18 is formed of a flat resin plate. The central portion 18a that covers the opening 13b is transparent, while the peripheral portion 18b that contacts the front panel 13 has a design coloring. Therefore, it is made opaque, and is adhered to the front panel 13 by an adhesive applied to the back side surface of the impermeable peripheral portion 18b.

On the other hand, reference numeral 19 denotes an auxiliary paddy receiving floor provided on the right side portion of the traveling machine body 1. The auxiliary paddy receiving floor 19 has a work posture that projects to the outside of the fuselage and a storage posture that extends along the outside surface of the fuselage. It is configured to freely swing and transform. That is, during work, it is projected to the outside of the machine so that paddy bags can be exchanged on the floor, while it is stored to avoid contact with ridges during non-work. The front side of the auxiliary paddy receiving floor 19 of the present embodiment extends to the front side of the engine room cover 20 (which covers the right side of the engine room, which is provided adjacent to the rear of the operation and operation section 5) and extends forward. In addition to being extended, the front half portion 19a can be compactly stored by folding the front half portion 19a over the upper surface of the rear half portion 19b.

Furthermore, reference numeral 21 denotes a boarding / alighting step provided in the boarding / alighting section 5 a of the driving / manipulating section 5, and the boarding / alighting step 21 is lower than the floor surface 5 b of the driving / manipulating section 5.

[Operation effect]

 In short, since the present invention is constructed as described above, the lighting device incorporated in the outer surface of the machine body is covered with the cover body, but the cover body has a transparent central portion. In addition, the rim is formed of an opaque plate member, and the luminaire is covered by bonding the opaque rim to the outer surface of the machine body. That is, unlike the case where the cover body is mounted using a fixing member such as a screw, it is not necessary to form a screw insertion hole in the cover body itself or to machine a screw screw hole in the mounting portion of the machine body, so that the shape is simple. It is not possible to achieve a significant cost reduction based on the reduction of the number of processes and processes, and it is possible to improve the installation workability by eliminating the need for troublesome work such as fixing screws at multiple points.

Further, since the cover body can secure sufficient airtightness by adhesion, there is no need to interpose a further seal member, and as a result, the mounting work can be further simplified. The number of parts can also be reduced.

Moreover, since the opaque portion of the cover body is adhered, there is no inconvenience that the adhesive penetrates the surface of the cover body and spoils the appearance, or the shape and color of the opaque portion can be freely changed. Therefore, there is an advantage that it can also be used as a member for decoration.
