## Claims

### Claim 1

A dust collector, comprising:
a dust collection vessel having,
an openable and closable cap,
a case,
an exhaust cylinder that has a filter and provided in the dust collection vessel, the dust collector filtering, by the filter, dirt and dust that have been sucked together with air from a suction port of the dust collection vessel, exhausting the air from the exhaust cylinder, and recovering the dirt and dust in the dust collection vessel,
a cleaning member that cleans the filter, and provided movably along an axial direction of the exhaust cylinder; and
a cap opening/closing interlocking unit that moves the cleaning member relative to the filter in association with an opening/closing operation of the cap, the cap opening/closing interlocking unit having a movable member which is movable in the axial direction with respect to the exhaust cylinder, a plurality of connecting members arranged at intervals around the filter to connect the movable member and the cleaning member to each other, and an urging member interposed between the exhaust cylinder and the movable member to urge the movable member in an extension direction with respect to the exhaust cylinder,
wherein, the movable member moves in a retracting direction against an urging force of the urging member by making contact with the case as the cap adopts a closed posture.

### Claim 2

A dust collector, comprising:
a dust collection vessel having,
an openable and closable cap,
case,
an exhaust cylinder that has a filter and provided in the dust collection vessel, the dust collector filtering, by the filter, dirt and dust that have been sucked together with air from a suction port of the dust collection vessel, exhausting the air from the exhaust cylinder, and recovering the dirt and dust in the dust collection vessel,
a cleaning member that cleans the filter and provided movably along an axial direction of the exhaust cylinder;
a cap opening/closing interlocking unit that moves the cleaning member relative to the filter in association with an opening/closing operation of the cap, the cap opening/closing interlocking unit having a movable member which is movable in the axial direction with respect to the exhaust cylinder, a connecting member for connecting the movable member and the cleaning member to each other, and an urging member that urges the movable member in an extension direction with respect to the exhaust cylinder; an accommodation portion for accommodating the urging member being provided on one side of the exhaust cylinder; and the moving member being arranged to cover the accommodation portion,
wherein, the movable member moves in a retracting direction against an urging force of the urging member by making contact with the case as the cap adopts a closed posture.
