Description of the Related Art In FIG. 1 of Japanese Patent Application No. 7-48137 filed earlier, a frame (reference numeral 16) extending substantially to the left and right of a revolving base is erected, and a tank hood and an engine hood are arranged so as to cover the frame. It has been proposed to establish one. And those bonnets were all made of sheet metal.

うにしておくことが必要になってきた。Since it is necessary to install driving unit protection equipment, such as a hood and a roof, above the driving seat of the backhoe to prevent the falling of earth and sand,
The support frame for supporting the support is raised from the swivel base. The appearance as a backhoe is formed by covering the periphery of the driving section with bonnets such as tank bonnets and engine bonnets containing hydraulic oil. Therefore, it has become necessary to be able to freely set the curved surface shape as required.

供することを目的とする。However, the conventional sheet metal bonnet has a limitation in shape setting, and it is difficult to respond to a great degree of freedom in design. In addition, a canopy or a cabin which is structurally larger than those of a hood or a roof is required. It seems that it is time to overhaul the upper structure of the backhoe, that is, the structure of the prime mover. In view of the above-mentioned circumstances, an object of the present invention is to provide a driving unit of a backhoe that is capable of setting robust and highly functional driving unit protection equipment and has excellent design flexibility for hoods. .
