、を設けたことを特徴とする円筒型緩衝装置。 A cylindrical shock absorber comprising an annular outer cylinder, a substantially cylindrical elastic body held on the inner peripheral surface of the outer cylinder, and a shaft member passing through the elastic body in the axial direction,
One of the outer cylinder and the shaft member is connected to an excitation source, and the other is supported by a predetermined support, and the excitation force from the excitation source is absorbed by the elastic deformation of the elastic body, and the other is supported by a predetermined support. In a cylindrical shock absorber that suppresses the transmission of excitation force to a body, first and second volume-changeable shock absorbers are formed inside an elastic body with the shaft member in between.
a communication chamber provided between the outer circumferential surface of the shaft member and the inner circumferential surface of the outer cylinder so as to communicate the first and second chambers; and a communication chamber sealed in the first and second chambers and the communication chamber. and a displacement member that is displaced within the communication chamber following the relative motion between the outer cylinder and the shaft member and generates shear stress in the viscous body in a direction that restricts the relative motion. A cylindrical shock absorber characterized by:
