A telescopic prop-up pole device of the present invention is configured to comprise a first pole; a second pole which is drawably inserted into this first pole, while being protruded; and a telescoping adjustment body for adjusting the protruding length of the second pole, the telescoping adjustment body being constituted by an upper cylindrical body; a lower cylindrical body; a pole pressure-contacting/releasing part including a pressure-contacting annular body having a protrusion and a coil spring; and an operation lever which, with a turning operation thereof, pushes up this pole pressure-contacting/releasing part, and the turning operation of the operation lever pushes up the protrusion on one side of the pressure-contacting annular body against the resilience of the coil spring for bringing the pressure-contacting annular body into the horizontal state to eliminate the bulging of one side and the other side thereof toward the circumference side of the second pole and thereby to bring the pole pressure-contacting/releasing part into the second pole releasing state, while, with the turning operation thereof being canceled, the pressure-contacting annular body is brought into an inclined state under the resilience of the coil spring with one side and the other side thereof being bulged toward the circumference side of the second pole and thereby the pole pressure-contacting/releasing part being brought into the second pole pressure-contacted state.
