Abstract
PURPOSE:To absorb vibrations of a cab at the time of cab set while preventing drop of the cab at the time of tilting the cab by such a construction that the function of the pilot valve to fix the action of the piston in oil pressure cylinder for the purpose of tilting the cab is put aside at the time of cab set. CONSTITUTION:The function of pilot valves 13a, 13b to fix the action of the piston 14 in oil pressure cylinder 9 for the purpose of tilting a cab is set aside by putting the head side chamber 10a of the oil pressure cylinder 9 in communication with the rod side chamber 10b at the time of cab set as well as leading it to detour through a check valve without being influenced by the pilot valve to be in communication with the main flow lines 8a, 8b, whereby drop of the cab can be prevented at the time of tilting the cab and, at the same time, vibrations of the cab at the time of cab set can be absorbed. Thus breakage of the device is prevented.
