In the above-described conventional cleaning tools, the cleaning head hits various objects such as a desk or a chair when cleaning a narrow place during repeated cleaning. To do this, the cleaning head turns around and rotates. However, since the handle part rotates around the horizontal axis, it is possible to change the direction of the cleaning head by changing the direction of the hand of the user holding the handle, but there is no change. If the cleaning head attempts to rotate beyond the range, the screws on the handle portion that are screwed loosen. By repeating this, the screw part connecting the handle parts is loosened and it often happens that it is retightened. In addition, when the cleaning head does not rotate well, the direction of the cleaning head must be changed, and it is often difficult to clean every corner when cleaning a narrow portion.

In a conventional mechanism for connecting a handle and a cleaning head, a pair of support portions rising from the cleaning head are formed integrally with the cleaning head body in order to connect the cleaning head and the connecting member. At that time, molding cannot be performed unless a split mold is used as a mold for forming such a support portion. In order to mold using the split shape, a step of closing and removing the split shape is required, which takes a lot of time and effort in the forming operation, and accordingly, there is a problem that productivity is low.
In addition, a complicated split shape is required, which may increase the cost of the mold, thereby increasing the manufacturing cost of the cleaning tool.
