Provided is a cleaning tool (1), which can switch and set a lock piece (50) disposed at the other of a shank (10) and a body (20), at a locked position and an unlocked position. The lock piece (50) set at the locked position abuts against the stopper face (41D) of an engaging member (41), thereby to hold the engaging member (41) at the engaging position of a recessed face (36). The lock piece (50) set at the unlocked position leaves the stopper face (41D) of the engaging member (41), thereby to set the engaging member (41) free for elastic forward and backward movements. |
