PROBLEM TO BE SOLVED: To reduce burdens on a user when lifting a suction port body. SOLUTION: In the vacuum cleaner, a point where the circular arc C11 of a radius 40 mm whose center is the center of a first virtual circle C1 of a diameter of 16 mm which is disposed so as to inscribe a corner part 71 formed of a grip part 8 and a stopper part 9 and be farthest from a first tube body 41 in the direction of a first axis 41a crosses the surface on the opposite side of a communication tube of a handle part 7 is defined as a first point P1. A point where a fourth virtual circle C4 when second-fourth virtual circles C2-C4 of the diameter 18 mm are arranged in the order in contact with the grip part is brought into contact with the grip part is defined as a second point P2. An angleθ(θ<90 degrees) formed by a straight line L1 connecting the first point and the second point with the first axis is not more than 15 degrees. COPYRIGHT: (C)2010,JPO&INPIT
