A cleaning tool comprising a first arm portion, a second first arm portion, a rotation portion, and a cleaning body attachment portion which is connected to the second first arm portion, the cleaning tool being capable of taking a stored state, wherein the rotation portion includes a rotation axis line, a rotation direction which includes an opening direction, and a depth direction along the rotation axis line, characterized in that the rotation portion includes a pushing portion, two or more first connection portions which are connected to one of the first arm portion and the second first arm portion, each of the first connection portions including a first shaft hole, and a second connection portion which is connected to the other of the first arm portion and the second first arm portion and includes a second shaft hole, the pushing portion includes a protrusion for rotation control which fixes an arm angle of the first arm portion and the second first arm portion, and penetrates the first shaft holes and the second shaft hole, the protrusion for rotation control includes a side surface portion which protrudes toward a direction orthogonal to the rotation axis line and extends in a direction of the rotation axis line, and a sliding portion which is arranged at an end portion on a deeper side in the depth direction, the second connection portion includes a plurality of hollows for rotation control which are arranged along the rotation direction, each of which including a base portion which is configured so as to receive the sliding portion of the protrusion for rotation control, and a wall portion for rotation control which fixes the arm angle by fitting with the side surface portion of the protrusion for rotation control, the rotation portion is configured so that a fitting of the side surface portion of the protrusion for rotation control and the wall portion for rotation control is released by pushing the pushing portion in the depth direction, and in the stored state, the second connection portion includes an opening direction inclination portion which makes the protrusion for rotation control move from a first hollow for rotation control which fits with the protrusion for rotation control among the plurality of hollows for rotation control to a second hollow for rotation control which is adjacent to the first hollow for rotation control in the opening direction, by making the sliding portion of the protrusion for rotation control slide, without pushing the pushing portion in a first wall portion for rotation control of the first hollow for rotation control. the rotation portion includes a rotation axis line, a rotation direction which includes an opening direction, and a depth direction along the rotation axis line, characterized in that the rotation portion includes a pushing portion, two or more first connection portions which are connected to one of the first arm portion and the second first arm portion, each of the first connection portions including a first shaft hole, and a second connection portion which is connected to the other of the first arm portion and the second first arm portion and includes a second shaft hole, the pushing portion includes a protrusion for rotation control which fixes an arm angle of the first arm portion and the second first arm portion, and penetrates the first shaft holes and the second shaft hole, the protrusion for rotation control includes a side surface portion which protrudes toward a direction orthogonal to the rotation axis line and extends in a direction of the rotation axis line, and a sliding portion which is arranged at an end portion on a deeper side in the depth direction, the second connection portion includes a plurality of hollows for rotation control which are arranged along the rotation direction, each of which including a base portion which is configured so as to receive the sliding portion of the protrusion for rotation control, and a wall portion for rotation control which fixes the arm angle by fitting with the side surface portion of the protrusion for rotation control, the rotation portion is configured so that a fitting of the side surface portion of the protrusion for rotation control and the wall portion for rotation control is released by pushing the pushing portion in the depth direction, and in the stored state, the second connection portion includes an opening direction inclination portion which makes the protrusion for rotation control move from a first hollow for rotation control which fits with the protrusion for rotation control among the plurality of hollows for rotation control to a second hollow for rotation control which is adjacent to the first hollow for rotation control in the opening direction, by making the sliding portion of the protrusion for rotation control slide, without pushing the pushing portion in a first wall portion for rotation control of the first hollow for rotation control.
