<P>PROBLEM TO BE SOLVED: To provide an air pump capable of stabilizing a structure and capable of improving usability when in operation. <P>SOLUTION: A head element 20 has an oblique surface 21 formed in outside end and a connecting part 22 arranged along a normal line of the oblique surface 21. The oblique angle of the oblique surface 21 is 45°. A whirling unit 30 has an oblique surface 31 and a connecting part 32 arranged along a normal line of the oblique surface 31. Circular step-like grooves 33, 34 of the connecting part 32 are used for installing the connecting part 22. Accordingly, the whirling unit 30 whirls between a storing position serially lining in a longitudinal direction of the air pump 10 and a developing position sandwiching an angle perpendicular or approximately perpendicular to the longitudinal direction, and the position can be switched. The air pump becomes convenient in operating and the structure can be stabilized when erecting the air pump 10 on the ground upon holding the development. <P>COPYRIGHT: (C)2013,JPO&INPIT |
