PROBLEM TO BE SOLVED: To secure a wide range of the safety from in the daily life to in the hobbies by absorbing light load in no need of heat treatment with the metal fatigue reduced and also heavy load quake and vibration after heat treatment because the position of the bearing point differs from the position of the base point. SOLUTION: A plurality of short and long metal plates are combined to constitute the deformation resistance at the bend, and the bearing point 3 is provided on the outside of the upper position of the second bend to absorb the occurring spring function, namely quake and vibration.
