Abstract
Conventional leaf blowers have a supporting frame to where the different components are attached. In order to reduce the noise from the tool and protect some of the components are they provided with covers. This makes the tool heavy and complicated for the operator to use. The claimed invention is a covering casing (10) that also is the supporting structure for the different components in the tool. The casing reduces the amount of noise spread from the tool and protects the components inside the casing (10).
