In a cleaner, a first end portion of a core member is supported by a first end support portion of a body member such that the core member is movable relative to the body member with the first end portion serving as an operating point. A recessed portion is provided in one of a second end portion of the core member and a second end support portion of the body member, and a protruding portion that fits into the recessed portion is provided on the other portion. The motion of the core member is restricted by protrusion/recess fit between the recessed portion and the protruding portion and is allowed in a state in which the protrusion/recess fit is released. At least one of the core member and the body member includes a converting portion that converts, when the core member is moved against the restriction to release the protrusion/recess fit, at least part of a force that produces the motion into a force that moves at least one of the recessed portion and the protruding portion in such a way that at least the one of the recessed portion and the protruding portion separates from the other to release the protrusion/recess fit. |
