  The present invention is connected to the main body so that the rotation connecting member having the outward projecting portion can rotate around a predetermined axis line and change the angle with respect to the main body with the outer projecting portion protruding. The present invention relates to a cleaning tool having a rotating connecting mechanism and a rotating connecting mechanism thereof.

  Japanese Patent Application Laid-Open No. 2004-147971 (Patent Document 1) describes a cleaning tool in which a handle fixture 2 is swingably connected to a brush head 1.

  That is, the shaft body 30 is inserted into the holes 31 a and 32 a provided at the lower portions of the swing member 31 and the pair of auxiliary members 32, so that the shaft body 30 is inserted into the pair of auxiliary members 32 at both ends. Is supported, and the swing member 31 is swingably supported around the shaft body 30. Both ends of the concave portion 11 in the longitudinal direction are formed in a shape suitable for fitting and supporting the pair of auxiliary members 32, and the pair of auxiliary members 32 are freely detachable from these portions.

Each auxiliary member 32 is configured to be press-fitted into the concave portion 11 with an appropriate force so that the auxiliary member 32 is not easily detached from the concave portion 11 in the assembled state fitted in the concave portion 11. Therefore, although this cleaning tool can be assembled relatively easily, it cannot be denied that it is not always possible to reliably prevent the cleaning tool from falling off.
