摘要： PURPOSE:To obtain desirable friction resistance between the plates without increasing the weight by so designing the device that the sliding members with the comb- shaped cross section are fixed on the plate end parts which are facing to each other and the teeth parts are engaged to each other slidably in the longitudinal direction of the spring plate. CONSTITUTION:The sliding members 5, 6 are fixed on the opposing positions of the plate end parts 1b, 2b of the spring plates 1, 2. The sliding members 5, 6 have the tooth part 7 and the notched part 8 alternatively to form the comb-shaped cross section. The tooth part 7 is engaged with the notched part 8 on the other side, and the teeth 7 are engaged slidably in the longitudinal direction of the spring plates 1, 2. When the plates 1, 2 are bent by the change in the load, the teeth 7 of the sliding members 5, 6 are rubbed against each other. By doing so, the friction resistance between the plates are increased as the number of the sliding surfaces becomes greater than that of the existing spring device.
