PROBLEM TO BE SOLVED: To provide a blade damper structure which can be substantially manufactured by extrusion molding. SOLUTION: A shock damper 1 is formed of a main body 2 including a space for storing at least one rotatable blade. The space is divided by the blade, and formed out of two partial spaces 6a, 6b varied in size according to the rotation of the blade. The blade is fitted to the main body 2 by a bearing member, and operated in a working medium 16 existing in the space. The working medium 16 is transferred between the variable partial spaces through a throttle function to produce a braking characteristic. The blade integrated with the bearing member is formed by finish cutting the extrusion molded aluminium, and each blade includes a seal member for sealing the associated surface of the space and the bearing member. |
