Mower

Abstract

A mower carried on shoulders or back to be used. A bowl-shaped contact member is disposed under a rotating body driven to rotate around a vertical axis as to be freely rotate around the axis. And, a bottom wall face portion of the bowl-shaped contact member has a flat face at right angles with the axis on a lower face. And, the bowl-shaped contact member has a curved face portion connecting a cylindrical peripheral wall face portion, of which center is the axis, and the bottom wall face portion.
