The door stopper of the present invention is of a construction such that a door contacting member fitted into a guide cylinder sunk vertically into the floor is allowed to be set in two positions, in a door contacting state in which it protrudes from the floor and in a housed state in which the top is substantially level with the floor. According to this construction, the floor is able to be substantially flat when the door stopper is not in use so that it does not become an obstruction to floor polishers and wheelchairs.
