In a configuration in which a ratchet mechanism is provided in which the support is automatically released as the ratchet is being lifted, one side of the link that is pivotally supported with the middle as a fulcrum is connected to a release member that releases the ratchet function of the ratchet mechanism. , the other side of the link is a link mechanism forming an abutting part, and b: a lever to which a presser member is fixed and which is swingable about a shaft is within a predetermined swing range of the swing. c: a lever mechanism in which the pusher material is in contact with the abutting portion; When the lever is swung to the other side by acting on the release member to release the ratchet function, the link is returned to one side about its fulcrum by the biasing force of the attached spring. , an interlocking mechanism of the lever and the link whose return restores the ratchet function; d: a state in which the lever is set at a swing end on the one side and within the predetermined range; , the setting transmits a signal for lowering the cab of the cab lifting device, and when the lever is set at the swing end on the other side beyond the predetermined range, A driver's cab lifting operation device, characterized in that the setting comprises a mechanism for transmitting a signal to raise the driver's cab of the driver's cab lifting device.
