Claims

[Scope of Claim for Utility Model Registration] A swivel base 3 is mounted on a swivel base 2 installed between the left and right running parts 1, 1, a driving unit 4 is provided at the front of the swivel base 3, and a driving unit 4 is provided above the swivel base 3. A backhoe is equipped with a canopy 9, a motor section 5 covered by a bonnet 6 behind the driving section 4, and a front attachment such as an excavator 7 attached to the front end of the swivel table 3. In this, the upper surface 6a and the rear surface 6b of the bonnet 6 are each formed into an inclined surface with a backward downward slope, so that the upper outer corner 6c of the bonnet formed by the upper surface 6a and the rear surface 6b is an obtuse angle, The minimum turning radius of the front attachment is the rear visibility radius L1 from the turning center line C of the turning base 3 to the ground surface position that the operator seated in the driving section 4 can see through the upper outer corner 6c of the bonnet 6. The bonnet structure of the backhoe is made smaller than L2.
