Abstract: PROBLEM TO BE SOLVED: To provide a door opener, by which a door open-close unit is miniaturized and lightened and a door can be opened efficiently by only one of the operation of a touch switch and which is silent. SOLUTION: In the door opener 1 opening the rotary type door 10 in which one end section is supported rotatably by a hinge, the door opener 1 has a motor 2, a screw shaft 4, which is housed in a bottomed cylindrical housing 3 and to which the rotation of the motor 2 is transmitted, a nut 5 screwed to the screw shaft 4 and internally inserted into the housing 3 and a spring 6 housed between the bottom section 3a of the housing 3 and the motor 2. A spiral thread groove 4a is formed to the outer circumference of the screw shaft 4, and slid and contacted with the thread groove 5a formed to the inner circumference of the nut 5 and the rotation of the motor 2 is converted into the linear motion of the nut 5. Since the nut 5 is formed retractively and irrotationally to the housing 3 and the screw shaft 4 is formed integrally with an output shaft of the motor 2 and the motor 2 is abutted against a shoulder section 3c formed to the housing 3, the screw shaft 4 is constituted rotatably but unretractively.
