PURPOSE: A temporary repairing apparatus of a flat tire for a vehicle is provided to travel normally by keeping internal pressure of the flat tire continuously during traveling by straining the tire with centrifugal force and by contacting with pressure changes. CONSTITUTION: A temporary repairing device of a flat tire is composed of a sealing unit(10) moving out of a tire(T), and shutting off the flat portion of the tire; an expansion unit(20) moving the sealing unit to the outside of the tire and the rim with centrifugal force; and a moving unit(30) combined with the expansion unit, and turning with the rim of the tire. A moving shaft(21) of the expansion unit is expanded out of the tire, and moved with rotating the tire during traveling. The moving unit is turned, and the sealing unit is moved around the tire with difference of centrifugal force in placing the expansion unit outside the tire. The flat portion of the tire is shut off with a housing(11) by suction force from outflow of tire pressure in placing the sealing unit in the flat tire. Lowering of the tire pressure is prevented, and traveling is performed stably with straining by centrifugal force.
