摘要： A shock absorbing device provided with a damping plate damper having a viscosity damper includes: a case body comprising an upper flange, a body portion, and a lower flange; a collared resilient member provided with a body portion and a collar portion, an outer surface of the body portion and an undersurface of the collar portion being connected to the case body; a center shaft connected to the central portion of the collared resilient member; a damping plate fixed to the bottom end portion of the center shaft; and a damper case fixed to the bottom end of the case body and filled with a viscous substance. An operator cabin of a construction machine is resiliently supported to the vehicle body through the shock absorbing device. For this reason, the number of natural vibration of the operator cabin during high speed running of a hydraulic power shovel is increased, whereby resonance thereof with the gear engaging frequencies of a caterpillar track and a sprocket wheel is avoided, so that effective damping effects can be achieved against the number of excited vibrations applied in wide ranges by the construction machines and the like, thus improving riding comfort for an operator and the mechanical strength of the operator cabin.
