A cleaning tool which, even if the distance from the center of a cavity to be cleaned to the inner wall surface defining the cavity varies, can clean the inner wall surface, can be pressed to the inner wall surface with a force having a varying magnitude, can clean the inner wall surface with force with the magnitude most appropriate for the degree of dirtiness of the wall surface, and can clean the inner wall surface only by being moved in the advance-recede direction relative to the cavity. The cleaning tool (1) has a core member (10) and a cleaning section (20) attached along the outer periphery of the core member (10). The cleaning section (20) has cleaning members (30) and a holding member (40). The cleaning members (30) are made from an elastic body, have a larger diameter than the diameter of an opening of the cavity (101), and have continuous annular outer surfaces. The holding member (40) has a smaller diameter than the opening of the cavity (101) and holds the cleaning members (30). The cleaning members (30) and the holding member (40) are installed on the core member (10) so as to be interchangeable and rearrangeable relative to each other.
