PROBLEM TO BE SOLVED: To improve easiness-to-functional use, while having a mechanism for revolving a suction tool by 90 degrees in the respective lateral directions by simple twisting operation. SOLUTION: This suction tool has suction tool bodies 1 and 2 having an opening on the cleaning surface side, and a joint part composed of a main joint part 5 turnably supported in the predetermined direction relative to the suction tool bodies and a sub-joint part 6 turnably supported in the direction orthogonal to the predetermined direction relative to the main joint part. The direction of the center line for connecting an intermediate point of a shaft for turnably supporting any one joint part of main and sub in the vertical direction and an intermediate point of a laterally turnably supporting shaft, and the installing direction of a connecting pipe 7 installed in the sub-joint part, are set in the same direction. A click constitution is arranged in a turning part turning in the lateral direction of the joint part. The suction tool revolves at substantially 90 degrees in the respective lateral directions, and force in the suction tool operation direction is distributed as operation, and acts on a vertically turnable shaft and a laterally turnable shaft of the main joint part, and operation follow-up performance and rectilinear stability of the suction tool are improved, and easiness-to-use is improved.
