Abstract

A handheld work apparatus includes a housing and a work tool arranged on the front end. The housing has a back end to which an operator region is assigned. The housing has a first and a second shell separable in a separation direction. The operator region, in the region of the back end, is bounded by a tubular section of an outer housing wall. The outer wall of the first shell is reinforced in the region of the tubular section by a rib structure inside the housing. In a view in the separation direction of the inner side of the first shell, in the region of the tubular section, the first shell has an interconnected rigid rib region and an interconnected elastic expansion region. The expansion region is directly adjacent to the rib region and is at a greater distance from the back end than the rib region.
