PROBLEM TO BE SOLVED: To provide an air filter cleaning device capable of accurately adjusting a lap amount of a brush and an air filter, and shortening assembly time.SOLUTION: An air filter cleaning device 10 comprises: an air filter 1; a rotary brush 2 which cleans the air filter 1; a case 3 in which the rotary brush 2 is installed; pinions 4, 4 being propulsion mechanisms installed in the case 3; racks 5, 5 being support parts supporting the pinions 4, 4; and a base material 6, in which a guide spacer 13 which is engaged with guide parts 12, 12 of the base material 6 and slides with respect to the guide parts 12, 12 is installed to the case 3. Then, with the engagement between the guide parts 12, 12 and the guide spacer 13, movement of the case 3 in a direction orthogonal to a direction where the rotary brush 2 makes reciprocating movement is restricted.SELECTED DRAWING: Figure 2 |
