PROBLEM TO BE SOLVED: To provide a door stopper which can be operated with reliability as a stopper, and which is excellent in manufacturing performance. SOLUTION: The door stopper is constituted by a cylindrical body 1, an axle material 2, and a spring 3. The axle material 2 is housed in the cylindrical body so that its tip can rise from/set in the upper end opening of the cylindrical body 1 by a predetermined stroke. Then the spring 3 is used for energizing the axle material 2 in the projecting direction at all times. A pin 4 which is projected in the radial direction is provided on the outer peripheral surface of the axle material 2, and a turning operation groove 5 is provided on the upper end surface of the axle material 2. A guide groove 6 is provided on the inner peripheral surface of the cylindrical body 1, and the pin 4 is slidably engaged with the guide groove 6. The guide groove 6 is formed by a vertically extended groove 6a, an engagement groove 6b continuously provided at the lower end of the vertical groove, and the inclined guide surface 6c guiding the pin 4 from the vertical groove 6a to the engagement groove 6b. Furthermore, the cylindrical body 1 is constituted of a united body of the upper body 1a and a lower body 1b which are separately molded by making the lower end of the vertical groove 6a a branch.
