PROBLEM TO BE SOLVED: To provide a vacuum cleaner having no fear that a dust collection chamber lid is broken even when a cleaner body falls down on a floor surface.SOLUTION: Linear pattern uneven part 10 is formed on both of front and back surfaces of a dust collection chamber lid 7 covering the upper part of a dust collection part 15 of a cleaner body 1, so that occurrence of stress concentration on a thin part is prevented by making the dust collection chamber lid 7 covering the upper part of the dust collection part 15 have uniform thickness, and the strength to impact is improved. Also, formation of the linear pattern uneven part even on the surface enables improvement in appearance without being formed with transparent or translucent material.SELECTED DRAWING: Figure 1 |
