Abstract
The autonomous travel working machine includes a working body unit, a cover unit, and a connecting structure unit connecting the working body unit and the cover unit. The connecting structure unit includes a body connecting section attached to the working body unit and a cover connecting section attached to the cover unit. When the cover unit is lifted, a shaft portion of the cover unit is slid upwardly with respect to a head portion of the working body unit so that the cover unit is moved upwardly or lifted with respect to the working body unit. When the working machine hits against an obstacle, an intermediate portion of the body connecting section is resiliently deformed in a lateral direction so that the cover unit is moved with respect to the working body unit substantially only in the lateral direction.
