HINGE SHAFT REINFORCEMENT STRUCTURE, AND A HEIGHT CONTROLLING DEVICE AND A CLEANER WITH THE SAME, CAPABLE OF ABSORBING IMPACT GENERATED IN THE CONTACT BETWEEN A HINGE SHAFT AND A PROJECTION
PURPOSE: A hinge shaft reinforcement structure, and a height controlling device and a cleaner with the same are provided to prevent damage to a hinge shaft due to external shock and improve the durability of the cleaner by forming a reinforcing member on the height controlling device of the cleaner.;CONSTITUTION: A hinge shaft reinforcement structure comprises a hinge shaft, and a reinforcing member(340). The hinge shaft connects two objects to be rotated. The reinforcing member absorbs shock so as to prevent damage to the hinge shaft. The reinforcing member comprises a projection(341), a shock absorbing rib(342). The projection is formed on one among the two objects. The shock absorbing rib contacts the projection in case of the generation of shock so as to absorb the shock. The shock absorbing rib is formed along the hinge shaft. The shock absorbing rib integrally formed with the hinge shaft.;COPYRIGHT KIPO 2010
