Abstract:
To provide a cab supporting structure capable of supplying a protection function with a simple configuration by using an attenuation mechanism (25) commonly used for a controlled vehicle for protecting the cab (2) or an operator from high impact force acting on the cab (2) while absorbing vibration and shock on the cab in a normal condition when a construction machine falls down. The cab supporting structure is provided with an attenuation mechanism (25) elastically supporting a cab against a vehicle frame (1). A regulation member (26), only when certain displacement is generated in the cab in the extension direction of the attenuation mechanism, regulating this displacement is provided separately from this attenuation mechanism. The regulation member (26) regulates the displacement of the cab (2) before a stroke end of the attenuation mechanism. Upon arranging an operation machine on the vehicle frame (1), the regulation member (26) is provided at least at the opposite side of the operation machine.
